    This should be straightforward, but I can't seem to get it right.

    I want to remove ExternalAccount permissions on a specific mailbox. Here's the command I use to confirm that the permission is present:

    Get-MailboxPermission user1 -domaincontroller dc1.contoso.com | ? {$_.accessrights -like " *ExternalAccount*" }

    Identity User AccessRights IsInherited Deny

    -------- ---- ------------ ----------- --
    contoso.com/Use... Contoso\User1 {FullAccess, ExternalAccount, ReadPermission} False False

    All good so far. Now I just want to remove the ExternalAccount permission assigned to Contoso\User1. Here's the command:

    Remove-MailboxPermission -Identity User1 -User " Contoso\User1" -AccessRights ExternalAccount -domaincontroller dc1.contoso.com

    The above command generates the following error:

    Remove-MailboxPermission : Can't remove the access control entry on the object " CN=User1,OU=User Objects,DC=contoso,DC=com" f

    or account " Contoso\User1" because the ACE doesn't exist on the object.

    At line:1 char:25

    + Remove-MailboxPermission <<<< -Identity User1 -User " User1" -AccessRights ExternalAccount -domaincontroller dc1.contoso.com

    + CategoryInfo : InvalidOperation: (0:Int32) [Remove-MailboxPermission], InvalidOperationException

    + FullyQualifiedErrorId : 78249DD3,Microsoft.Exchange.Management.RecipientTasks.RemoveMailboxPermission

    Any thoughts on this?

    Hi Michel

    Thanks very much - you were right on the money!

    The ACE entries were pointing at the sIDHistory value, but were being displayed via get-mailboxpermission as the target domain account. Confusing!

    Anyway, I now have a script that runs Remove-Mailboxpermission using the sIDHistory value for the -user parameter. Works like a charm.
