Thunderbird lost 6000 emails possibly during Compacting. 4GB mbox limit for 32bit ?
Hello.
We are using Thunderbird ESR v128 32bit. Windows 10 64bit.
Had some 14000 emails since 2012, all working good, incl. recent compacting 2m ago. Today there was another folder compacting running, possibly it didn't end as usual (no message, no error).
Since then we can see for about 6000 most recent emails only header, not the body nor attachments. Tried to repair the folder, it made 6000 headers disappeared completely.
When we checked Inbox and Sent mbox files in profile via text editor, last bottom entry/email there is from 2018 and the files are exactly 4 GB in size.
Is it possible that some 4 GB 32 bit Thunderbird limit was hit and that truncated the large mbox files?
Is there any way to find somewhere on local disk (some temp folder or files) the most recent missing 6000 emails?
Account is using POP and the files are not stored on mail server.
Thank you for any advice.
