Azure AD: Main User Corrupted

Question

I was working well with my Azure credential before the Azure AD outage on Monday 15, 2021. Today I can access well to the Azure Portal but when I connect via PowerShell I found that it's not connecting to the correct Tenantid. When I look for the user in Azure AD I see the user has been altered showing a username with a weir structure and #EXT# in the middle.

The issue is that the user can access well to the AZ portal, can't access to my corresponding Tenantid via PowerShell and the user see changed.

Any idea?
Thanks,

Hi @Alberto Leonor · The text #EXT# in the UPN refers to external (guest) user. All guest users' UPNs are in this format. It doesn't mean that user is corrupted. It is sometimes confusing when we see User type as member for these users, which happens when we convert guest user to member user.

A user can be added as guest user to multiple tenants and when we connect via Connect-AzureAD PowerShell cmdlet, it gets connected to one of those tenants. In order to connect to a specific tenant, we need specify tenant name by using -TenantId switch, when connecting to Azure AD, as shown below:

Connect-AzureAD -TenantId tenant_name.onmicrosoft.com  

You can also specify the TenantID as GUID as well in the cmdlet.
