I've set up access to another mail account for some users, however, I'd like to know who sent mail from/as that account. Is this possible?
user1@myorg is granted full access to the mailbox user2@myorg.
Using OWA, the user can access his mail account at
and "user2"s at
However, if the user is sending mail from that account, I can not find any entry in the log indicating that "user1" sent the mail, and not someone logged directly in as "user2"
Is it possible to set up Exchange so that this information is stored/logged?
