User's contacts missing data
I have one user whose mailbox is on O365. For many of his contacts, the phone and/or email address is missing. He made no changes to the contacts that he is aware of. The contact name is still there,...
I have seen instances where Android Devices synced with the account will cause this. I would look into what o/s his mobile devices have and what version and then look into known issues or bugs. Likely it will end up being a sync issue from a mobile device. If you have access to eDiscovery - you can likely recover the contact data if it wasn't too long ago.
