I am trying to setup someone's account in so they can download multiple mailboxes in outlook on different domains hosted on the same exchange server. Here is the setup:
There are three different domains hosted on the same exchange server, he has three seperate user accounts, one under each domain. In outlook, he has setup his login under domain1 as the exchange login, and then added his mailboxes on domain2 and domain3 under "More Setting/Advanced" when configuring the Exchange Mailbox.
On the exchange server, his user account under domain 1 has been given full mailbox rights and delegate permissions on the account under domain2 and domain3.
He's able to see the exchange folders for his accounts on domain2 and 3 in outlook (actually just domain2, I think the privileges haven't moved through the system yet for 3), but he cannot send mail as those accounts on domain2 or 3. He is able to send mail under his account on domain1, which is the user account associated with the exchange mailbox in outlook.
Is there a setting I should need to configure other than giving him full mailbox rights to enable him to send as his account under domain2 or 3?
He gets this error when attempting to send:
"You do not have permission to send to this recipient. For assistance, contact your system administrator."
