That is bizarre and we have not had anything reported like that. I looked at the ticket you started at 1:30am and we will need much more than the handful of log lines you sent. Can you please update your ticket with:
1) What was the previous version of SM you were running prior to 8797?
2) Have you done other updates to your server?
3) Did you restore or delete any files on the server?
4) Did you use other tools or clients recently?
5) Did you update or change Outlooks?
6) Please provide a list of users with the issue.
If you want to speed things along, you can also submit an RSA so we can take a look once we have the information above and have an idea what to look for.
I'm guessing the account on the server itself doesn't show duplicates and Outlook it is the only thing showing duplicates. If sync issues are going into deleted, that means Outlook lost its conifugarton information.
