Current version is broken. It claims to find duplicates, then hangs TB. Running latest Mac Ventura, TB 102.12.0, POP from gmail.

One of the most useful extensions you can get for Thunderbird. Excellent, thank you!

The May 6, 2023 update has absolutely broken the Remove Duplicate Messages add-on. It runs forever on a folder with just one or two dozen messages, none of them duplicate, and no longer reports "no duplicates found". So sad. It used to be a valuable tool.

It worked very well for me. After recovering my emails from a backup file, I had a lot of duplicate emails, this module saved me a lot of time and drastically reduced the number of emails. It is very easy to use.

It worked perfectly for me. I believe the people that it isn't working for haven't set the search properties correctly on the add-on. If the message has ever been moved on the source end, then the message ID will be different and not seen as a duplicate. Just uncheck message ID and check date& time, sender, receiver, subject, and body are the same, and check save the first message.

THANK YOU. just saved me more days of manual deleting.
Wish I found it earlier, before deleting half of 97000 duplicates.
Couldn't work out why hard drive was full.

Nachdem ich den Größenvergleich abgeschaltet habe, hat das Add-on doppelte Dateien in verschiedenen Ordnern von zwei IMAP Accounts gefunden, sehr schön. Allerdings wird in der Tabelle nicht angezeigt in welchem Account die doppelten Mails gelöscht werden. Die Ordner heißen gleich "Posteingang".

I had about 39,000 email with thousands of duplicates it seemed. At first this addon removed a few then didn't find any although I could find them. I changed the settings which are found in the Tools, Add-ons page, click on the wrench icon to access settings. I removed the size comparison (I think the developer recommended this) and added the recipients comparison. It found 18,000 duplicates. I think it's still moving them to trash! After tweaking settings I am pleased and recommend the developer look into whether not enabling the the size comparison as a default will yield better results.
This review is for a previous version of the add-on (0.5.2b4).Remember I must err on the side of caution when it comes to duplicates; it's better that I fail to find them than I find messages which I'm not certain the user would want deleted. So - I don't believe I can't safely relax the criteria.

It hangs Thunberbird when applied to a folder with 150.000+ messages

Worked like a charm on one of my email Inboxes but not the other (I have Inboxes for 2 different email addresses). The other one is causing all kinds of problems because it is so overloaded with dupes.
UPDATE A FEW DAYS LATER ... Started working on the other folder too! Not sure why, but everything is good now so I'm changing my rating to 5 stars.

It would be useful to add a temporal shedulator that in the background (with policies created) acts every time interval on the selected folder

I have thousands of duplicate mails that are identical except for being one line different in length. I don't know how they got that way. I can remove the number of lines from the comparison rules but that would be dangerous since there are too many to manually inspect. It would be great if it was possible to specify a tolerance so that I could ask for "at most X lines different in length". Using 102.2.2 and latest plug-in.

I have mail that was migrated from GSuite into privately hosted IMAP server. Due to how mail is structured in gmail (labels etc) there is a fair amount of duplication. This addon did remove a lot, but a lot of seemingly obvious duplicates are completely ignored. These duplicates tend to have large attachments (10+Mb), if that is perhaps a factor. Otherwise they have identical subject lines, timestamps etc.
But credit due - the plugin DID help me eliminate maybe 10Gb worth of duplicates in that account, so it does kinda work.

Very handy, especially when filters you've created don't work quite as you expected. This will set things right, easily.

Hello,
I try to use your extension to manage an archive mailbox, and it works fine manually by clicking on the button.
Have you any hook to make it possible to automate the process, because I intend to launch Thunderbird from the command line at regular intervals of time automatically.
It would be quite nice a agreat added value for my usage.
Thank you for your response at flr(at)free.fr

Going from a mailbox with 110000 emails, to 45000. Thank you! I had mistakenly imported my emails twice. Saved by this plugin. I changed the criteria to compare to email body, and when i saw the review before deleting duplicates, some emails were even in there 3 times. but no more. Thank you!
