@vasileios Thanks for the advice. I am able to fill in the account setup “form” in Thunderbird but I am unsure what to put in for authentication method, my choices are: Normal Password, Encrypted Password, Kerberos/GSSAPI, NTLM, TLS Certificate, OAuth2. No matter which option I choose I get
BTW when I clicked “Fix Now”, I got a banner that said it was fixed but the pink banner saying it is not configured properly is still there. I feel I am so close to getting this up and running. Cheers and Happy New Year!
