You are seeing this with version 115?

I am having this same exact issue with the latest software update.

I am having the same issue with 115 update. What are the server settings for incoming email now? Thank you.

Thunderbird brought down my email from AT&T for a few hours correctly and for about a week for about 1-2 times a day. However, several days, ver 113.3.2 (64-bit) stopped downloading and giving me the same "email is being processed" error message. Is someone trying to figure this problem out? AT&T says it is not their problem but also say they know about it.

as of 12/11/23 I am having same/NEW problem: Account is being processed... Please wait... Meanwhile NO MESSAGES are being downloaded. Is there a FIX?? Release 115.5.1 (32-bit)

Does this also reproduce with Windows started in safe mode?
