Hi

What do you mean by "Migration to Office 365"? Did you enroll the device into Intune?

Are the contacts still present in Outlook on the desktop or in mobile?

The user was on exchange and was migrated to Office 365.

Users' device was registered to Intune and the user lost all personal contacts on the Phone.

Contacts are not present on either phone or iCloud.

Now the user is able to add new contacts but unable to edit the contacts on the Phone.

There isn't anything in Intune that should cause this.
Maybe there is just another contact list open on the phone?

We are having the same issue with mutiple users.  When they install InTune after O365 upgrade on Verizon iPhones - all their personal contact cards are missing.  It wipes them out and creates all the contacts in their O365 email.  We cannot figure out a way to get them restored.  

The only way we know how to stop it is to have them select to not sync Contacts when installing but that doesn't help us when the users have already done that - on getting them back.
