How can I force iPhone to resync contacts from server?
Solution 1:
Maybe you've already tried this but I'll suggest it anyway.
Check Groups
- Open Contacts
- Tap the arrow in the upper-left corner labelled Groups if it exists.
- Ensure you have selected the right group of contacts.
Try Re-Sync
If you need to re-sync because the above did not work you could try this:
- Open the Settings app
- Open Accounts & Passwords (or the Mail section on older iOS).
- Select the account causing problems. (Usually called Exchange.)
- Turn Contacts off and tap ‘Delete From My iPhone’ when prompted.
- Turn Contacts back on and tap ‘Sync’ when prompted.
