Folder corruption on 94.0b1 (64-bit) Windows 10
In the last week folder corruption has become common which is very worrying. Emails appear to become duplicated but on folder repair emails get lost totally.
This has happened on the inbox repeatedly, even after compacting, rebuilding, and emptying.
It has also happened on the Sent folder plus local folders.
Is this a known new problem? (I could not see it listed here.)
If this persists I will have to migrate elsewhere. I looked at Mailbird but that can’t import the Thunderbird local folders tree. I have thousands of folders and hundreds of thousands of emails stored which appear to be at risk.
Any suggestions please? Best would be a Thunderbird fix, but in the absence of that what alternative can best preserve my history?
