A user account was removed from Azure in the past 24 hours so in turn their mailbox was removed automatically. I have not been asked to see if it was to late to recover the mailbox and make it a shared mailbox?

    Hi @ rr-4098 ,

    If you do not permanently delete this user and mailbox, you can recover them within 30 days by following these steps:

    1.  Open Azure Active Directory

    2.  On the Users - Deleted users page, select the user who was deleted by mistake.

    3.  Select Restore user.


    Then wait a while to check whether the users in M365 Central - Users - Active Users and the corresponding mailboxes in Exchange Admin center have been automatically recovered.

    If not, you can also refer to the following steps to restore the user in the M365 admin center:

    1.    In the admin center, go to the Users > Deleted users page.

    2.    On the Deleted users page, select the names of the users who you want to restore, and then select Restore.

    3.    Follow the prompts to set their password, and then select Restore.

    4.    If the user is successfully restored, select Send email and close.
