I am running an sbs 2011 system. It has the following version of exchange:
Microsoft Exchange Server 2010 SP2
I have a particular account that needs access to another users mailbox.
I have set the full access permission (so they can view the mailbox and check the emails) and also the send as permission, so they can send email as the other user.
However, send as is not working, when I try to send as the second mailbox, from the first user, I get the following error message:
"You do not have permission to send on behalf of the specified user."
I understand that send on behalf of, takes precedence over send as, but I have not deliberately set send on behalf of permission, so I don't know why in this case, send as is not being recognized.
Any help would be appreciated.
