I sync email, contacts and calendar to my company's Exchange server. This morning all of my contacts are gone from my iPhone (iPhone 4, iOS 4.2.1). Facts that further explain:

  • My contacts were good last night
  • I haven't synched to my computer, updated any apps or changed any settings since then
  • I'm getting email and my calendar entries are all good.
  • I see all my contacts when I log into the web mail interface to the Exchange server

Is there a way to tell the iPhone to wise up and realize that it has screwed up its contacts?

Maybe you've already tried this but I'll suggest it anyway.

Open Contacts and tap the arrow in the upper-left corner labelled 'Groups' if it exists. Ensure you have selected the right group of contacts.

If you need to re-synch because the above did not work you could try this:

  1. Open the Settings app
  2. Open Mail, Contacts, Calendars
  3. Select the account causing problems
  4. Turn Contacts off and tap Delete From My iPhone if prompted
  5. Turn Contacts back on and tap Sync when prompted
