Recent migration from Ex2003 to Ex2010. Users created on Ex2010 seem to work. Older users can turn on OOF but even when they turn it off again the Autoreply still goes out! OWA show it is off, Outlook shows it is off - Autoreply still gets sent.
Interesting note: Using Outlook 2010 (me as sender, user with problem recipient) the Mail Tips shows only when OWA shows it is turned on. If turned off in OWA, Mail Tips in Outlook2010 does not display message. Message gets sent to user and Automatic reply comes back to me.
We have found a tool called MFCMAPI where we can force it off but it keeps cropping up from time to time. I'd like to find why.
Anybody have any ideas?
