Thunderbird quitting and duplicating messages in Trash

more options

I have recently started using Thunderbird 115.4.3 on a new laptop running Windows 11. I transferred my profile from my old laptop and set up my two email accounts as POP accounts. The problem is that Tbird is regularly crashing, mostly (maybe only?) when I delete messages from my Inbox. When I restart the program, it works fine except that all or most of the messages in Trash are now duplicated multiple times. Any ideas how to stop this behavior?

The increased inbox volume of your pop account will be full?

It is usually expected that storing a lot of email increases the risk that too many inbox files could also be damaged. (popstate.dat file)

These could respond with the answer that the entire inbox is downloaded again from the pop server. It may spit them back into your trash can, which is remarkable. Would you mind emptying it?

do you leave the messages on the pop server? is this checked? why not just choose imap?

Hello there

To solve the situation. If trash and trash.msf e files are still present on your computer in the Thunderbird software, you could delete them both so that they can be reindexed.


Thunderbird crashing caused by what? Does it give error messages? That you can forward?
