We are using Exchange 2003 SP2 with Outlook 2007 clients.
Let's say I have to users - Manager and PA.
PA has 'Send on Behalf' rights to Manager's mailbox.
So, if PA sends an email, and in the From: field enters Manager, the email is received to me as:
(Displayed in Outlook Inbox) From: Manager@domain.com
(Displayed in actual message) From: PA@domain.com On behalf of Manager@domain.com
So, I assume the following:
MAIL FROM: PA@domain.com
However, if I send this to an external recipient (e.g. my Hotmail address), then there is no 'Send on Behalf' shown, it just appears to come from Manager@domain.com
Any ideas why this is? Does 'Send on Behalf' not work to external recipients?
