0365 Shared mailbox delegation doesn't dissapear in user's mailbox after removing 0365 accounts RRS feed

  • Question

  • Dear,

    The next issue is about a 0365 environment.

    I have a user who have delegated access to 2 e-mail accounts.
    The 2 e-mail accounts are removed from 0365 but the shared mailboxes are still in the user's mailbox.

    We have checked the Account Settings but in the Advanced settings there are no mailboxes configured.

    Is there anybody who knows what to do?

  • Hi,

    Maybe you can try to remove the delegate access/full access permissions for the user from the mailbox using Windows PowerShell. You can do this with following command:

    Remove-MailboxPermission -Identity <Mailbox ID1> -User <Mailbox ID2> -AccessRights FullAccess

    Note, in this command, <Mailbox ID1> represents the mailbox to which the user is granted permissions, and <Mailbox ID 2> is the mailbox of the user from whom you want to remove full access permissions.

    For how to Connect to Exchange Online Using Remote PowerShell, please refer to this article.
