After creating an account in O365, the user cannot access Outlook Online, cannot configure local Outlook, mobile Outlook. And also can't connect to his mailbox via the IMAP protocol.
I also observe a problem with deleting users. After revoking the user's license and deleting it via admin.microsoft.com, the user disappears in Azure AD but remains visible in admin.exchange.microsoft.com . Even after forcibly deleting a user in Azure AD.
If I try to delete a user through Exchange Online PowerShell, I get the following error
PS /Users/redhat> Remove-Mailbox -Identity Removed for privacy

Are you sure you want to perform this action?

Also when the command "PS /Users/redhat> Get-Recipient Removed for privacy | fl"
In the output I see "OrganizationalUnitRoot: Removed for privacy ", although we previously added a new domain Removed for privacy , and the previous domain was deleted. Removed for privacy

this happens to all newly created users.
