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.

You're getting the error because the reply address is set to another address.

When sending a message on the behalf of someone, you use their default reply email address.  You can't send 'from' an alias address.

One way to get this to work would be to create a Distribution Group or user mailbox for the alias and give send as permissions on the alias for your user account.  (You would make your user account a member of the group so that you can continue to receive incoming mail or put a forward on the mailbox).
