Potentially great when re-creating/re-importing emails, but not working reliably on Thunderbird 115.4.3 on Windows 10. Intermittently crashes Thunderbird resulting in lost emails and corrupted mbox files. Would otherwise give 5 stars.

I just migrated from eM Client. All of my messages were duplicated upon import to Thunderbird. I downloaded this add-on for this reason. I had to work with the parameters, and make less demands on it, but it finally worked. All duplicates gone. Thanks!

確かに重複メッセージを削除できました。 しかし、 不具合も存在しました。 不具合がなければ満点でした。

初期設定のままだと ほとんどの重複メールを削除しません。 重複メッセージだらけの場合でも検知しません。 [重複メッセージはありません] と表示されるだけです。 設定を以下の通りに修正しなければいけません。

----------------------------------------------------------------------
■Message ID → □

■サイズ → □

□本文 → ■
----------------------------------------------------------------------

[右クリック → 重複メッセージ検索用の設定] は無反応です。

[重複メッセージの削除] を押下しても無反応の時が有ります。 再起動すれば なおります。

表示順番が Thunderbird と ことなります。 具体例として、 Thunderbird の日付順表示だと [じょうだん が未読、 下段が既読] で表示されています。 この時、 検索結果画面で [下段のメッセージのみ保持] をせんたくすると、 下段の既読メッセージのみ保持されなければいけません。 しかし、 実際には じょうだんの未読メッセージが保持されてしまいます。

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

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.

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.
