The extension does a good job of finding duplicate emails. There are many comparison criteria. The main drawback for me is the search results field is too narrow (680 pixels). I have 3440 pixels wide, and I can afford to examine the search results table in detail without having to guess the values ​​of cropped cells or using horizontal scrolling. Especially when the number of found groups is several thousand.

It works great except on "special folders", like sent mail. In migrating email to another host some duplicates happened and this add-on would have been perfect to clean this up, if not for this one limitation.

Edit: the author notified me of a setting to toggle this behaviour, so no complaints now!

The extension _does_ work on special folders - if you ask it to, in the options dialog. By default, it skips them, because usually people don't want to check for duplicates with folders like Drafts or Archive where one often has copies of the same messages.

Seams to work quite well. Would be nice to be able to preview the email before deleting

This has the potential to be a great tool, but unfortunately, it does not work with TBird 115. Will this addon be upgraded?

Very useful for pruning my mailbox, and also I'd really appreciate an option (or another add-on) to "show me what's in this folder BUT NOT in that folder" (a variant of what Remove Duplicate Messages does at present). I can do this (slowly) by copying all messages in A to A2 and B to B2, running RDM between A2 and B2, then what remains in A2 and B2 is the result I'm after (can be used for consistency checks or to identify missing messages). A variant of the add-on to do this without copying would be great.

I used to sometimes check and delete duplicate messages across different folders. But recent Thunderbird updates have removed the "select multiple folders" option, which has broken/limited the functionality of this useful tool. I hope the extension developers will raise this with Thunderbird developers.

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｡
