How to delete duplicate mail messages using Mail Script

Great post/tip Bradley, thanks! 🙂

Thanks for the info.

Somehow this morning I managed to "mark as junk" an entire Folder and when I pulled it all back from the Junk Folder to the originating Folder - it created duplicates.

You would think APPLE would have something like this built into their Mail Software by now. iTunes has had this function for a long time to weed out duplicate Songs.

I guess it keeps 3rd party developers in business though.

Brilliant - worked flawlessly 🙂

mac.com is no longer available. anyone have a pointer to the script that works?

works for MOUNTAIN LION (10.8)?

I have found this at Download.com but hasn't tried it yet.

Need to get a new USB drive for TimeMachine first.

Doesn't work with Mountain Lion.

This is such a basic issue with mail *arrrgh*

I'd buy an add on to do this. In fact, I would buy a lot of mail add ons to do various mail-related stuff.

I've used TBird in the past but that app is now EOL. I'm reluctant to switch to a 3rd party app like Postbox because of fear that it too will stop being supported and I will be left holding the bag.

This seems like a business opportunity. Surely someone can point me to either a plugin for mail or a freestanding app that does this.

*sigh*

in Mountain Lion you can use this script: http://jollyroger.kicks-***.org/software/RemoveDuplicateMessages-Mail.zip

where *** = "a s s"

works like a charm! tested personally

cheers

Thank you. The http://www.andreasamann.com/MacOSX/Mail_Scripts link is good as of today, 9/24/12.

The "remove duplicates" script worked perfectly for me, removing hundreds of duplicates. It does it in a way that lets mail sync back the changes to icloud's imap server, which then allows you to clean up the rest of your macs mail with a simple Mail menu "Mailbox>Synchronize" command on your other machines. Lists OS 10.4-10.6, PPC or Intel, system requirements. Apparently 10.7 breaks "some" of the scripts. You could always fire up an older machine, sync mail so that it is current, run scripts, sync, and you'd be done. The changes would then sync back to your 10.7 or 10.8 Macs.

I had tried Tidy Up v2 & 3 for deleting duplicate mail messages, which it did, but in a way such that with the next mail sync the duplicates were all replenished again.

I'm getting an error http://d.pr/i/VANb

This doesn't work in Lion nor Mountain Lion.

I've tried that one too. Thanks though

I ran the script on OS 10.6 / Snow Leopard. Worked as advertised. If you had access to an account on another machine running 10.6 or earlier then you should be able to clean up your Mobile Me/iCloud mail and then sync back the changes to your later generation OS mail account.

Works perfect on Mac OSx 10.7.5. Thanks a lot!
