Hello 

I am using Thunderbird for a long time. Great app.

I have a problem with 128.2.2 esr. After upgrading to this version i am unable to send emails with an Office 365 account from my work. Same settings with outlook are working great no problem

when i am sending an email it does nothing... just says sending....if i press cancel i get ..sending of message failed. unable to authenticate to outgoing server smtp. Please check the password and verify the Authentication method in Accounts Settings smtp. (all settings are good)

if i just let the window after a couple of minutes ...i get Sending of the message failed. the message could not be sent because the connection to Outgoing server smtp timed out . try again

windows 10 22 h2 - 128.2.2

thank you in advance
