Hi All:
If a user has send As permission to a mailbox xyz and he sends a message to
someone using xyz in the FROM field (so its coming from user xyz), is there a
way to find out who actually sent this email?
For example charles has sendAs permissions to a user mailbox called xyz.
Charles changes the From field of the message from charles to xyz. Other
users have sendAs permissions to xyz as well. Looking for a way to find out
which user actually sent the message out of all users that have SendAs
permissions.
Well, we have a long list of users that have SendAs permission to the
mailbox in question so cant figure it out that way (just see who has SendAs
permissions).
Thanks in advance!
Charles
