Massive number of duplicates on contacts.

I'm getting thousands and thousands of duplicates on contacts. (30,000 and counting, but only have 250 genuine approx).Same on my imac, iphone and ipad. Have done all obvious things including merge duplicates and deleting and reloading contacts. I have 2 accounts on contacts, outlook and iCloud. iCloud list is the problem. Outlook list OK.



iMac 24″, macOS 14.6

Hopefully what you are seeing is some type of local corruption and not real. Try this:


  1. Back up your Mac with Time Machine - Apple Support
  2. Remove the iCloud account from the Mac: Remove or temporarily turn off email accounts in Mail on Mac - Apple Support
  3. Restart the Mac: Shut down or restart your Mac - Apple Support
  4. Login to iCloud.com using a web browser and inspect the contacts as they are listed on the server. Troubleshoot the issue, merge, delete, etc. there if necessary.
  5. Add the iCloud account back to the Mac: Add email accounts in Mail on Mac - Apple Support
  6. Check your contacts
