neomutt gets stuck at sending message

[Chakkramacharya]

I have followed steps twice..and they work perfectly. I got my outlook account configured on it.. But when i send message neomutt gets stuck at "sending message.. "

it gave a gssapi is not a valid authenticator" error in my first attempt and mail gets stuck here..

I searched for gssapi error and got a link saying this issue is closed and to use sasl.. Pl clarify how to use it.. and maybe this should be a part of the installation instructions ?

I am using wsl2 on windows .. ubuntu Thanks

The error snapshot is attached
