Can IMAP Thunderbird use POP folders?

I just upgraded (reluctantly) to Win11 on my desktop, and my POP Thunderbird account did not survive the upgrade. I had to switch over to a new IMAP Thunderbird, losing all of my POP folders (which are still on my disk). Just not, apparently, accessible.

Anyone have info on how to re-access or somehow get them into my IMAP install?

In that case, the old profile is likely intact, and you may be able use "Import" in the updated Thunderbird to bring the messages in from the old profile.

First, thunderbird does not disallow POP. if you upgraded, your POP account was not dismissed; more likely, thunderbird created a new profile. Your old profile is still there and can be reactivated. If you want to continue as IMAP, let us know and maybe someone here will assist in the transition. On the other hand, you can reactivate your POP account instead. Let us know. thank you
