Duplicate emails in sent folder
How do I eliminate duplicate emails in my Mail sent Folder? I am using Apple Mail 16 on iMac Monterey 12.6.7 with a hotmail (Outlook) account. There are lots of suggestions on line but none of them work (though they might have with older software versions on Mac or Outlook).
I have no Rules set up in Mail > Preferences > Rules for my account and i tried remove my hotmail account from the Mail app on my Mac, as suggested by MichaelB2019 (Community Specialist) in a pass conversation with the same title, but after reconnected my hotmail account i didn't trigger it to fix itself and the same problem reappeared.
This problem does not occur when I use Mail on my iPhone or Outlook app and Outlook online on my mac, so I presume the source of the problem is Mail on my mac.
Any ideas on a fix ?
iMac 27″, macOS 12.6
