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

Turn up diags for Send As in ESM or Powershell depending on your
version of Exch.
