I have a user who has multiple aliases for multiple domains which are handled by the single Exchange server. For instance, this Exchange 2010 server receives email for domain.com and domain.us. This user had a primary email address of User@domain.com and an addiitonal email address of User@domain.us.
User is running Outlook 2013. He would like to be able to use the "From" field to switch to User@domain.us when needed.
In my experience, I was able to do this by creating a separate mailbox, and then furnishing "Send As" rights for the primary user. From what I am aware, a user cannot use "From" to toggle to send as an alias. Am I wrong?
During tests, the user received the following error when trying to use the alias to send:
Delivery has failed to these recipients or groups:
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.
Thoughts? Thanks in advance.
