I wasn’t very clear I think - the issue is running outlook 2003 in cached mode with the avast Outlook/Exchange provider on the client.

The main issue we were seeing is that every message that was sent to a mailbox was being copied into the Synch Issues - Conflicts folder. The messages would have the click bar on top that read “you made changes to another version of this item” even though we hadn’t. Looking into the message innards, there was mention of Avast somehow tagging the message, maybe as safe? Dunno. I turned on logging on the Outlook side and viewed the server smtp logs, but nothing jumped out at me.

I prolly should have started new post, eh?
