Recently a client complained that an Office 365 account had sent out spam messages to a number of clients. Later, the suspect account which had been sending spam could no longer send or receive email. However upon first glance at the mailbox, sent messages were sitting in the sent items folder, and messages sent to the account in question were not receiving bounce-back failures, but the messages sent to the affected account were not in the inbox. After we changed the password to the account, and enabled 2FA on the account we could still not send and receive mail. Below are the steps used to resolve this particular issue. In short, a malicious inbox rule had been created and outbound messages had been blocked by Microsoft.
Log into the tenant’s Admin console with an Administrative account, and change the password of the affected account.
Log into the affected account as the user using the new password.
Click on the Gear icon and then under Your app settings, click Mail.
4. One in the Mail app Settings, go to Mail > Automatic Processing > Inbox and Sweep rules.
Here we can see a malicious rule had been created to mark all inbound mail as Read and move the message to the “RSS Subscriptions” folder:
5. Uncheck and turn off any malicious or invalid rules.
Also check for any new forwarding rules in Mail > Accounts > Forwarding:
6. When we look in our “RSS Subscriptions” folder we find some messages from Microsoft indicating the account has been blocked from sending mail because the account was flagged as sending spam:
Your message couldn't be delivered because you weren't recognized as a valid sender. The most common reason for this is that your email address is suspected of sending spam and it's no longer allowed to send messages outside of your organization. Contact your email admin for assistance.
Remote Server returned '550 5.1.8 Access denied, bad outbound sender. For more information please go to http://go.microsoft.com/fwlink/?LinkId=875724. S(9333) [DM5PR10MB1914.namprd10.prod.outlook.com]'
7. To resolve this issue, we’ll need to go into the Action Center. Log into the Admin console > Admin Centers > Exchange > Protection > Action Center
8. In the Action center, we’ll find an issue flagged regarding our hacked user account. Take action on the issue and after a while due to permission propagation, it may take up to 2 hours for the account to be re-enabled for sending mail again.
9. It might be a good idea to contact Microsoft Support if you continue to experience problems with a user account sending spam. Changing the password should prevent malicious access. Most like the account had been phished or the computer the user has was compromised by a virus/malware or spyware. It’s recommended that the account have two-factor authentication or multi-factor authentication enabled to prevent the account from being hacked again.

When trying to setup and authenticate to an AWS Instance running OpenVPN, a user could not complete a new connection to OpenVPN after entering the initial un/pwd. They receive the error: Permission denied. This is after successfully setting up the OpenVPN client on Windows 10 and scanning an Authenticator code using Google Authenticator App on a Samsung S8 Active Android mobile phone running Android 8.0.0 ‘lollipop’. Ultimately the reason the user could not authenticate was their mobile phone’s time was off by about 3 minutes. Continue below to find additional information on how to troubleshoot this and other authentication issues with OpenVPN.
When troubleshooting OpenVPN login errors it’s a good idea to first try some of the following:
Unlock a Disabled or Locked account on OpenVPN Admin console
To check for the events related to a user lockout, first log into the Admin web console > Status > Log Reports. Here you will find the errors related to bad authentication and eventually an account lockout.
The errors you may find could be the following:
Google Authenticator Code is incorrect.
LOCKOUT: user temporarily locked out due to multiple authentication failures.
To unlock a user account (if using local authentication), Login to the Admin Web Console, Go to “General” under Authentication and change Authentication to “PAM”, Save Settings > Update Running Server > “Local” > Save Settings> Update Running Server.
This procedure should unlock disabled or locked user accounts on OpenVPN.
Reset A User Account on OpenVPN
To reset a user’s OpenVPN account:
Log in to the admin web console, click on User Permissions.
Find the username, place a checkmark in the Delete column, then Apply > Save. Next, re-create the account. Scroll to the bottom of the list, type the new user name: Eg. jcoltrin Save > update server
Go back find the username again in the list and hit Show:
In the admin web console, under the Configuration menu, click License. Check to ensure that your concurrent users have not reached or exceeded the limits of your licenses (under At a glance,) or that your licenses have not expired.
Use SSH to check the logs of the OpenVPN server and get the specific errors for an individual’s login problems.
After logging into the server using Putty/SSH, you can change directory to the scripts directory:
cd
/usr/local/openvpn_as/scripts/
and then issue the command ./authcli –user <username> –pass [email protected]
This will produce something similar to the following information:
Result:
API METHOD: authenticate
AUTH_RETURN
status : COM_FAULT
reason : An error occurred while connecting: 13: Permission denied. (twisted.internet.error.ConnectError)
user : jcoltrin
Addtionally you can find more messages related to authentication failures in /var/log. You’ll find these messages in the latest log files:
openvpnas.log
openvpnas.log.1
Use your favorite editor (vi) to search through the logs
vi openvpnas.log
use the command / and then the username to search for that term and hit “n” to go to the next instance of your term, for example:
/jcoltrin > n > n
and then :q to quit.
Here are some typical error messages for my authentication errors:
2019-02-26
14:20:08-0800 [-] WEB OUT: '2019-02-26 14:20:08-0800
[UDSProxyQueryProtocol,client] Web login failed
(twisted.cred.error.UnauthorizedLogin)'
2019-02-26 14:21:30-0800 [-] WEB OUT: "2019-02-26 14:21:30-0800 [UDSProxyQueryProtocol,client] Web login authentication failed: {'status': 1, 'client_reason': 'LOCKOUT: user temporarily locked out due to multiple authentication failures', 'reason': 'LOCKOUT: user temporarily locked out due to multiple authentication failures', 'user': 'jcoltrin'}"
Make sure the phone with Google Authenticator has the correct time and set the phone to sync it’s clock with the network/carrier
As mentioned at the beginning of this article, what the original login issue came down to was the Android phone, on which the Google Authenticator was running, had it’s time off by about 3 minutes. To set and change the correct time on an Android Galaxy S8 Active, first, go to Settings > General Management > Date and Time > Set/Turn on Automatic Date and Time.
I’m not sure why the value for this phone had it’s time set to not have automatic sync with the network/carrier. This may have been due to a recent android update because I found this setting off on a couple phones in the office. Ensure the time on your server is accurate as well by issuing the bash/ssh command:
After having created a Resource Room in the Office365 Admin console (with an Enterprise E1 license,) you may find that meetings which are created in Outlook and which are sent, are not automatically processing and sending verification confirmations back to the person that created the event. Nor will new events populate the event in the new room’s Outlook calendar. In this case, there are a few things we can check to ensure the room behaves as intended.
First, after creating the room, ensure that you, as an admin, are set as an owner of the room. Under O365 > Admin Center > Rooms and Resources > place a checkmark next to the room in question. Ensure that Allow repeating meetings and Automatic Processing is On. Then, click on Edit Exchange Settings:
2. In this example, we don’t use booking delegates. In the Exchange Settings for the new resource room, make sure Booking requests are accepted automatically.
3. Edit the booking options, contact information, email address, and mailtip settings to your preferences and then click on Mailbox Delegation. Here, add yourself under Full Access so that we can go on to our next step.
4. Next, log into your own OWA admin Outlook online inbox. In Outlook, click your profile photo in the upper right corner and click “Open another mailbox.” Type the address of the room and open the webmail for the room.
5. Here you may see some emails of previous attempts to book events like the following with the error “Your calendar couldn’t be checked to see whether this event conflicts with other events.“:
6. This error lets us know that automatic processing is not working even though we have it set to “On” in our first step. Had the processing worked correctly, we wouldn’t even see this event email in the mailbox of the room in question.
7. In the upper right corner, click the Gear icon, then under Your app settings, click Calendar.
8. In the calendar resource scheduling settings, ensure that under the scheduling options, “Automatically process event invitations and cancellations” is checked, and then click Save.
9. In theory, these settings should be enough to get the calendar to auto process and verify, however, your results may vary. Test by creating a meeting event in outlook with the new room. When you send the meeting, you should receive a verification email in your inbox in less than a minute. If you don’t receive the verification, check the inbox of the calendar again. You’ll probably find more emails with the “Your calendar couldn’t be checked…” errors.
10. Time to open PowerShell and connect to your O365 Exchange. If you’ve enabled MFA (two-factor authentication) use the guide on how to connect to Exchange with Hybrid/Modern Authentication here. If you don’t use Modern 2FA authentication, use the following commands:
12. It’s helpful to first get a list of all calendar processing objects of a room that already works correctly to refer to when editing your new room’s permissions. If you don’t already have a room that you can reference, below is a list of my room that is not behaving normally:
13. Notice that ProcessExternalMeetingMessages is set to False. Let’s change this to True with the following command:
14. After making this and a few other changes displayed in the following screenshot, go ahead and try creating another test meeting and see if the autoprocessing behaves as it should. If you’re still having trouble, try referring to the screenshot below as an example, and use the “Set-CalendarProcessing” command to edit the values.
15. Once you successfully receive verifications and the calendar populates with events as it should, you may want to set the calendar to display the owner of the event and details of the event (rather than the event is listed in the calendar as only “Busy”.) To do so, follow the instructions I wrote in my article here.
Occasionally we’ll be required to set a user account on Office365 to never expire. It’s not advisable to perform this action, as a compromised account who’s passwords never expires can be a liability. However, in some cases a utility account such as a scanner/copier or kiosk account may require a password that does not change. The following tutorial will show you how to set an Office365 password to never expire using PowerShell.
First, we’ll want to ensure that the account password is not already set to expire and we want to confirm it’s status. Using PowerShell we can get information about an Office365 user account password expiration status.
1. Connect to Microsoft Online Services with PowerShell by running the following commands:
Import-Module MSOnline
Connect-MsolService
2. Next, replace <UserID> with the user account (email address) of the user’s properties we want to get with the following command:
3. Because we get the message returned that the property PasswordNeverExpires = False, we want set it to $True and set the account password to never expire with the following command:
Because our PasswordNeverExpires property is now set to True, our task is complete. Disconnect from Office365 and close powershell by entering the command: exit.
When attempting to move files in SharePoint Online Office365 from one folder to another you may find that you get errors or the moving process times out or fails with the error:
Error: We couldn't move the file because it's locked for editing or has been modified or deleted.
What has happened is some of the files in these folders have been marked as “checked out” or “locked”. This may have been done erroneously by a user or the status was corrupted when the files were originally uploaded into SharePoint.
Once the files are checked in, you can move them. As an alternative to moving the files, you may also be able to “Copy To…”, and then delete the original files. Again, you may not be able to delete the files you copied because the files you want to delete in SharePoint may also be locked or checked-out.
This is what worked for me:
Use your favorite web browser and log into your SharePoint site (e.g. https://companyname.sharepoint.com/sites/sitename.
Browse to the problem folders that contain files that you cannot move to another folder.
In the folders, you should find files that are “checked out”. The files will have a green arrow icon next to the file icon.
Place a checkmark next to the file that is checked out.
In the menu at the top-right choose “…”
In the “…” menu, click “Discard check out”
Now try moving the file with the following sequence:
If the problem files are Word/Excel files, you may need to Open the files in Word or Excel first, in order to check them back in.
At some point, a user’s mailbox will reach the default quota for Enterprise E1 default of 50 GB, and they will have to either move mail into an archive or delete mail to continue to receive email. The user may receive the warning:
Your mailbox is near the maximum storage limit. Archive or delete items to create additional free space.
Our options at this point is to do one of three things: Upgrade the user’s license from E1 to E3 to double the mailbox size, permanently delete mail out of the mailbox, or archive the mail. Microsoft provides 50 additional GB of archive space for an E1 license (this number is subject to change.)
In many instances, the user may not want to delete any mail and would prefer to archive the mail. In my opinion, the ideal way to handle archiving is to create an online archive, rather than create .pst files on the local machine which could end up getting lost or deleted. Also managing local .pst archive files can be a pain. And lastly, if the archive is only available as a .pst file in the user’s PC, the archived mail will not be available from webmail or a different device.
If we want to create an online archive for the user on Office 365, there are a few simple steps to take in the Office 365 Admin console.
Log into the Office365 Admin console, then click on Admin centers > Security and Compliance:
Next, on the navigation bar, expand Data Governance, and click Archive
Now on the right-hand pane, we will see all of our mailboxes and find out if the Archive Mailbox for Office 365 is enabled or disabled.
To enable the archive on a disabled user’s mailbox, first select the user. If we have a lot of users, do a search for the user’s name and then highlight the correct mailbox we want to change.
We can see in the screenshot above, my account already has Archive mailbox: enabled. If the account’s archive had been disabled, we would simply click the Enable link. When we click enable, we will get the following Warning:
If you enable this person's archive mailbox, items in their mailbox that are older than two years will be moved to the new archive. Are you sure you want to enable this archive mailbox? Yes No
9. Click Yes.
10. What happens next is, as the warning states, mail that is over 2 years old will begin to be archived. We will also get some new features in both Outlook online, as well as in Outlook 2016/Outlook 2013. We can wait for the auto-archiving to take place, but we can also take some immediate action to archive old mail online.
11. Pretty much immediately in Outlook online, we will get new Archive buttons, and an archive folder here:
We won’t see the archive buttons until we click on an individual message. If we do click on a message and select it, we will see the Archive button available.
12. We can also select multiple emails and then right-click on the highlighted messages. A wizard will appear on the screen. Click the Archive button to move these emails to the archive folder.
13. If reducing the size of the mailbox immediately is our goal, we can start by archiving our largest emails first. At the top of the mail folder, whether it be the inbox, Sent Items, or Deleted Items folder, we’d click the Filter button > Sort by > Size.
14. Select the “Enormous” items first by clicking on the top email, hold down the Shift button, then select the bottom email and it will highlight all of the messages in between. Next, right-click and choose Archive.
15. In the desktop version of Outlook 2013/2016, only after a few hours will we have our new Archive folder available. This may take up to 24 hours depending on the speed of replication of settings from Office 365 down to the client. Once the folder is available, however, I find the process of moving mail out of the inbox, sent items or cut/paste of subfolders into the archive much easier.
I don’t have mail over 2 years old in my mailbox, so I’m not sure if it will automatically create subfolders dependent on where they originally lived so let me know in the comments if you notice automatic folder creation.
In order for someone to find an old message, they will only need to search their mailbox in Outlook online or Search Archive in Outlook 2013/2016.
On Office365 SharePoint, when trying to open a file in the Windows File Explorer, you might get something similar to the following error:
An error occurred while reconnecting Z: to (sharepoint location) - Web Client Network: Access Denied. Before opening files in this location you must first add the web site to your trusted sites list, browse to the web site, and select the option to login automatically. The connection has not been restored.
….or clicking the Open With Explorer button does nothing, or the button is greyed out.
If the button is greyed out using Windows 10 Edge, Edge does not support Active X controls, so go the Start button, type in Internet Explorer, open IE 11, and try again.
To get to the Open in Explorer button.
Log into https://portal.office.com
Click on your apps menu and choose SharePoint
Browse to a document library > Documents
In the bottom left corner of the browser click the “Return to classic SharePoint”
Place a check mark next to a folder, click on the “Library” tab at the top of the screen, and then click “Open in Explorer”
To resolve, make sure you have the following:
Windows 10 is up to date (v1803) as of this article
The Webclient service is Started and set to Automatic (Start > services.msc )
Make sure the following sites are added to your Trusted Sites in Internet Explorer settings:
https://yourdomain-files.sharepoint.com
https://*.sharepoint.com
https://login.microsoft.com
https://portal.office.com
https://yourdomain-myfiles.sharepoint.com
Next, restart your IE web browser, open IE, log into Office 365, and try again.
It may be beneficial to reset IE to its default settings:
IE > Gear Menu > Internet Options > Advanced Tab > Reset (delete personal settings) – use caution, try the following first, then if still having issues, try resetting your browser.

Let’s go baby, squads up!
BR’s different from multiplayer. Different vehicles and stuff.
I’m waiting for tomorrow – I’m so excited! (COD Blackout on PC)
Mike Told story about how he broke his arm/elbow. “I don’t remember how much it hurt. It hurt a lot. I do remember when I took the cast off. Yeah my mom said move it. So I whipped my arm straight and it hurt so bad. She said yeah you can move your arm but she didn’t say slowly so I whipped it straight and you gotta tell me very specific instructions or else I’ll F it up.”
I could probably be alone the rest of my life, because I got you guys I’m not really alone am I?
I could probably survive on my own. Hopefully, I’ve never had a lonely feeling because I was always online.
Where’s Troy now? He’s downstairs, he’s sleeping. We put him in doggy day-care.
We are social animals and we need social interaction. I agree but I always have social interaction since I stream.
I think I’m supposed to announce something. Luckily everyone in the gaming community is pretty chill.
12:45 AFK PUBG – (Africa by Toto)
New Shroud Skins! (Hype!)
You ready for some more Shroud Skins?!
Look at those gloves!
It’s 4 skins, M16, Gloves, Bandana, and the Jacket.
It’ll be $14.99 crate tomorrow.
Think about it like you’re sending a 15 dono to me.
Wow, thumb grip is not very good on this gun (UMP).
I don’t know how long the new shroud skins will be available for.
Troy, no. Why are you chewing on the chair?
This gun is so weird. Lightweight feels kind of good actually.
AFK to take Troy outside 1:10PM PST
I didn’t see the final draft (skins). I wanted to see how it was finished, but I like the way they turned out. The gloves are sick. I really like the gloves.
I like the M16, I think it looks the best as a weapon to skin. I hate SKS I hate minis, QBZ is ass, M24 is boring. I think the M16 pulls it off the best. I could have picked any gun. It fit the skin I was going for. Also look how the 4x blends in with the skin. This has been in the works for a long time.
You can use all kinds of gift cards to subscribe, subway, best buy, Walmart gift cards. Twitch has over 300 ways to subscribe to a channel.
I think the new gun ADS speed is lower.
You know what they should do? Hear me out. They should come out with a Shroud Weapon Skin Package. Every single weapon. But it’s a gamble. It scrolls through 5 different weapons and you have to hope it lands on your weapon.
