I opened Thunderbird to find that the folders I had created under the Inbox had all disappeared (I had simply added folders for the year in question...2021, 2020, 2019 etc and I place emails I wish to save in the year they were created). I am still receiving emails as normal.
The suggestion is that Kaspersky may be involved in some way.
Any suggestions would be most appreciated as to how I get my folders back.
