Review for Remove Duplicate Messages by helkav
Rated 5 out of 5 stars
I've tried both this and "remove duplicate messages (alternate)" .This addon works best because it allows more fields to be checked. It finds many more dupes than alternate, and because you can check the message body too, you can be positive that the results are correct and just hit the delete dupes button when the results window appears.
FYI Thorsten: I am currently using TB daily (24.x) , TB EarlyBird and TB 17.x and it works on all of these
