Thunderbird and OAuth2

Currently I have 2 email accounts:

Account A: IMAP/SSL, normal password, I do not set "save password" for this account Account B: Office 365 account with 2FA configuration. IMAP/SSL with OAuth2

I have got both Account A and Account B set under Thunderbird 78.5.1 (I have got ~/Library/Thunderbird removed, for a clean setup).

Initially, both accounts work very well. But after standing for a while (maybe after half an hour), when I click some random folders under Account A (the non-oauth2 one), Thunderbird asks for password. At the same time, no issues are found for Account B (oauth2 account). Removing Account B will solve the "ask for password after standing for some time".

This puzzles me: why would the OAuth2 account (Account B) setup would affect the behaviour of non-OAuth2 (Account A) account behaviour? Thanks.

i think, in your TB = Thunderbird, you need to enable specific cookies for OAuth2. so, either, you have to specify+allow specific URLs into Cookie-"Exceptions" (more secure), or, enable cookie for all sites . ( then, ALL type of wanted & unwanted cookies will be stored in TB, so its not a good/safe choice). please find my answer here (and goto 7th-bullet-point to see what you need to do with Cookies), & please also check this webpage (it may have LIST of specific URLs for mail-server that you're using now), & use those instructions/portions that is useful for your case. (please upvote my Q+A there if its helpful)
