Not finding duplicates in big folders coming from other program.

[vieira-temes]

Hi.

Using TB 128 (ESR) with ver. 0.6.0 of the addon.

I have two local folders, Inbox (86576 messages/20GB) and Sent (7439 messages/8.3GB). I knew for a fact that there would be lots of duplicates in there.

The addon can't find a single duplicate. emClient found 18386 in Inbox and 1564 in Sent.

I created a duplicate message in one of the folders and the addon could find it.

Both folders were uploaded to Thunderbird from Mailstore Home (using that software, not using Thunderbolt to import them).

Don't hesitate to ask me anything that might help you find the cause of this.

Same or similar problem. Using TB 128 (tried every 128 Version I can get) portable Version with 0.6.0 of the addon.
In local and in IMAP in every folder the addon can't find any duplicate. The Folders are imported from an older TB version but only the local folders. All IMAP folders are "downloads" from outlook.com.
OS: Win 11.
I tried also 115 vers of TB portable and old beta and new 0.6.0 vers of addon. nothing worked.

And I found a solution finally (works now with TB 128.4.1esr (64-Bit) portable version. I changed the settings like in this link https://support.mozilla.org/en-US/questions/1453832
then it worked. Maybe try to uncheck: Size (header and body) when I had it checked sometimes it works sometimes not. It is frustrating to try but maybe it is a problem of having Size and send time both checked (made problems one checked worked most time best worked for me only send time checked size unchecked).
And another problem I got was: Accidentally clicked on: Original. After that I could do what I want never found duplicates (even with "skip special folders" unchecked...
Hope this will help someone.
