Exchange 2013 sp1 cu7
A user sent a message to everyone in the GAL.
From Outlook 2013, if you hit ‘reply’ on this message, the recipient that appears in the To: field is not the original sender, but is someone else in the GAL.
From OWA, if you hit ‘reply’, the To: field shows the original sender. The original message was not sent from OWA as our users do not have access to it.
In the header of the message in Outlook, the Reply-To & Return-Path fields are different
How did/could this happen?
Thanks!
