Exchange contacts and GAL updates

[jeffmoss26]

Hey guys - trying to figure this one out.
We use Exchange on premise. The owner of the company has his contacts shared out so his assistant can make changes to them.
Each employee exists as both a contact in his Outlook, and an entry in the GAL. She periodically makes changes like extension numbers or phone numbers, and all appears to be fine. Then a day or so later it will revert to whatever is in the GAL.
I found a setting in for updating contacts and told it not to update, on both clients (Outlook 2013 and 2010)
Is there anything else I am missing here? I told her I could make these changes via AD but that does not fix anything.

Check to see if this helps you. I had the same issue with a client recently and I found they had the Outlook Social Connector. It was keeping a log of the changes in the Notes fields. Once I removed the Social Connector, it stopped.
