I have a user with a mailbox.
He was given full access to the mailbox with this cmd: Add-MailboxPermission -Identity "mailbox" -User "username" -AccessRights "FullAccess"
And also gave him send as persmission: Add-RecipientPermission "mailbox" -AccessRights SendAs -Trustee "username"
I've done this with another user also. But the problem is it's only working on the one mailbox - the other user get a error message:
Delivery has failed to these recipients or groups:
user You can't send a message on behalf of this user unless you have permission to do so. Please make sure you're sending on behalf of the correct sender, or request the necessary permission. If the problem continues, please contact your helpdesk.

Why does it work on the one PC but not on the other PC?
Any ideas?
