"Follow Up Suggestions" in Mail App causes deleting a bcc message to delete the sent copy as well.
I recently got a new iphone (IOS 16.5). I discovered that if I bbc myself on a message or simply send myself message that if I delete the message from my inbox, the copy in sent messages is deleted as well.
Looking through the community discussions I saw other people having a similar problem:
- Deleting emails where I am BCC'd from the inbox
- Mail, iOS 16: Deleting the Bcc also deletes the Sent message
No solution was given.
I did some testing and discovered that if I turn off the "Follow Up Suggestion" feature in mail under settings that the problem for me goes away. I.e. if I delete the message from my inbox, the copy in sent messages is no longer deleted as well.
I could not add to those discussions, but I'm posting my solution to help anyone else who may have this issue. I suspect it is a bug in Ventura and not just on the iphone.
