I'm running in our office Microsoft Exchange 2003 email server. The clients are running Outlook 2003 with all the latest updates, junk mail filter turned on and outlook in cached mode. all clients have NOD32 installed with Emon enabled, Imon off. Here is the problem, not sure if it is NOD32 related. We are getting a lot items in the Sync Issues/Conflicts folder. I have noticed that when new emails come into the inbox, some say at the top "You made changes to another copy of this item. This is not the most recent version. Click here to see the other versions." If i check the conflicts folder, the same message is there. If i delete the new message from the inbox, i can check the deleted items folder and the message shows up as two items. My guess is, one is from the inbox, the other from the conflicts folder. Here is what i have tried to narrow down the problem? Turned off Cache mode. This fixes it but it is not an option for everyone. Turned off Outlook Junk e-mail filter on the client side. This reduced the amount of conflicts by a lot, but i still got some duplicates. I turned off Emon, and re-enabled junk mail filter again, so far no duplicates. Has anyone else experience this scenerio and has found a good fix. Seems strange that turning off Emon fixes the issue in cached mode. Sounds like there might be a problem with Emon.
