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!

Literally saved me hours of work when my son accidentally downloaded over 5K dupes!

I would like to give this more stars. On some folders this generates an error message 'Not searching special folders.' What are 'special folders'? How do we fix this? Any help? What is the criteria?
Otherwise it seems to do what it says on the tin, and works on some folders.

I am so annoyed. This well reviewed add-on seemed promising. It doesn't work correctly though and seems to have deleted most of messages in multiple folders even though I triggered it just for on folder. If Eyal checks these I would appreciate his help because messages are supposed to be sent to trash but are nowhere to be found!!!

Addon broke a couple of months ago. Couldn;t find Trash folder and would not delete duplicates. Just saw updates and installed them. Still does not work. I even gave the guy a $50 donation when I saw the updates because I thought he had fixed it and I like the addon so much... how humiliating.

Love the add-on. However, most recent update seems to work only on top directory (hidden choking with the search subfolders option). Running fedora 33 w/ latest t-bird ( Thunderbird 78.11.0)

Quando funzionava, era molto utile...ora sulla 78.xx fa i capricci, almeno su ubu64...quando avrò tempo, cercherò di debuggarlo...

This add-on works great with Thunderbird 78.9.0 on a Mac running Catalina.

Like others, I got zero results at first. Fixes:
- Restart Thunderbird
- Tools > Add-on Options > Remove Duplicate Messages and change filter settings.
Under "General Settings" I left all defaults on. Everything checked. Default action "Move to Trash"
Under "Message Comparison" I kept *everything* checked except Size (important!) and Folder and set "Time Comparison Resolution" to Seconds.

Found 7K duplicates. Created a duplicates local folder and dumped them there. Yay!

Hello Patrick, or whoever else is reading this review. Please open an issue on the repository's GitHub page about this, and perhaps we can get to the bottom of why this restart is necessary.

Finds exactly zero duplicates :(

This review is for a previous version of the add-on (0.5.1b2). 

This is likely because your messages are nearly-duplicate, but not quite dupes. Consider relaxing your comparison criteria.

in th 78.6.0 ha funzionato benissimo.
La libertà di scegliere quali criteri usare per considerare due email uguali e pericolosa ma utlilissima!!!
;-)
Io l'ho usato per sfoltire alcune cartelle, usando solo il "subject" come ciretrio di uguaglianza.
Che per altro è la ragione per cui mi ero messo alla ricerca di addon.

This worked very well for me, Thunderbird 78.8.0 on Windows 10. I did have to tweak the settings a bit following the advice in the other reviews. I found it surprisingly fast finding the dupes.
