We have a user who has e-mails belonging to another user in his
mailbox. (From or To doesn't contain the first users name!)
The e-mails are in the Work In Progress folder.
When you open an e-mail the From field contains the other persons name
and e-mail address. The two don't know each other or have ever
e-mailed each other.
Both are in different post offices under different domains and
different FiD's.
We are in the middle of the GW8 -> GW2012 transition,
so back end is GW2012SP1, clients are (mostly)GW8 and GW2012.
Weird, isn't it?
