Single user keeps losing contacts

I have a single user on Outlook 2010 that keeps losing his contacts. We're on exchange 2013 latest patches. I've verified that the user isn't accidentally deleting them. I will restore his contacts from a backup file and within a day they're gone. Sometimes I'll find them in his deleted items folder. I've got his retention policy set for 90 days (don't think this has anything to do with problem).

I'm at a lose.

Thanks.
Richard

Can you check the mailbox type, is it is an user mailbox or room? If it is set to room change it to user mailbox.

This started about a week ago. We recently (about 3 weeks) were in a coexistance with exchange 2010 but that server has been decommissioned.

Does Powershell have you tied up in knots?

Is this user configured to run Outlook with Cache mode? If yes, move old OST to other location and recreate profile again. Sometime OST corruption also causes this issue.

No, all users do not use cache (GP).

I am asking for this specific user. Doesn't this user had any handheld device like iphone or ipad, might be handheld sync is causing this issue.

This user isn't using cache and we've removed his mobile device from the network (exchange).

then enable mailbox level auditing for this user. If issue reoccurs again you can track it down.

Hasn't happened in a while so not sure if it fixed itself or if the user just deleted all contacts and created new. Most of his were out of date anyway.
