If you have multiple M365 tenants you may encounter an issue when logging into Microsoft Entra. You may get errors such as “You do not have access.” or “Insufficient privileges to complete the option.” or “No subscriptions, You do not have any Azure subscriptions in the (tenant name) directory. Click here to switch to another directory” or “Error Code: 403. “You may see this occurs even when you log into M365 in a new browser or in incognito/private mode. Common sense would dictate this was a cookie or session issue, but the issue persists across browsers and sessions.
To resolve, you’ll want to click the “Bell/Alert” icon in the upper left corner of the screen and “Click here” to switch. Or click the Account icon (usually your initials in the upper right corner of the screen) and choose “Switch Directory.”
Now we will see a Portal Settings page with Directories and Subscriptions. Here we can switch to the tenant we want to manage. Do this by clicking the “Switch” button on the tenant we want to manage with Entra.
That should do it, let me know if you find a cause or reason for this issue occurring in the first place.
