Thunderbird has stopped downloading mail from the outlook account for my prime account, but my secondary account also outlook is OK. It kept asking to sign into my account then directed me to a web page to sign in for outlook, but it would only let sign into the 2nd account. I have tried uninstalling Thunderbird and re-installed it but still have the same problem.

TBird captive/internal browser not giving DUO local access

Hello,

Tbird 153.0 (64-bit) on Windows using the Owl extension for microsoft authentication.

Everything was working fine till about 1 week ago. Apparently Cisco changed something and now I'm getting a TBird browser prompt that our Multi-factor authentication(MFA) DUO needs 'local access'. This is coming up in the 'captive browser' (I believe that is the terminology). This is the message:

Duo Desktop needs permission to access your local network.

Duo uses local network access to communicate with Duo Desktop. When prompted by your browser, please allow this permission.

I never really get a prompt to respond to this in Firefox or any other browser.

If I continue I'm dead in my tracks with this (also in the internal captive browser):

Allow local network access

Duo uses local network access to communicate with Duo Desktop

   Click the site information icon left of the web address in your browser.
   Click the toggle next to Local network access to allow access.
   The page should refresh automatically and allow you to continue.

This link is provided which isn't really helping:

https://help.duo.com/s/article/9470

Does this sound familiar? Can TBird use firefox instead of it's captive browser or allow the captive browser local access?

Thanks in advance!

This just happened today. I'm using Windows 7 and Thunderbird version 115.18.0 (32-bit) . No settings have been changed and, there have been no problems signing in to my accounts until today. (I have a few accounts handled by Tbird.) The Microsoft sign in window comes up for me to sign in but there is no longer an option to sign in with your password so, I can't sign in and use my accounts in Tbird. I did click on "other ways to sign in" but no "sign in with password" there either.

Thanks for your help,

P.S. Wow. Crazy stuff. I closed Tbird and reopened it and, the previous Microsoft sign in window came up with the option to: "sign in with password". I am assuming it was fixed by restarting Tbird. Anyhow, "back i business" again.
