This morning, the issue has suddenly resolved itself across all Win 7 machines in the house.  Can someone from Avast tell me what's going on so I know what to fix when it happens again?  I hate disabling the mail shield making the machines more vulnerable.

This is so frustrating!!!  It is happening again across all systems, Windows 10 and Windows 7.  Newest Thunderbird (68.12), newest Avast.  For all IMAP accounts (hotmail, gmail) across all machines I get "Connecting to..." then "Connected to..." but it can never get to the "Sending login information..." part so once again Thunderbird has IMAP access blocked by Avast.  The only solution is to disable Avast and I can get mail again.  Can someone from Avast please, please explain what is happening and what is the solution rather than just waiting for it to randomly work and not work?

Unfortunately, I've already tried that the last few times.  The only way is to disable the Mail Shield in Avast.  I'm so tired of it I think I will disable the Mail Shield permanently, but does that leave my PC vulnerable or will the File Shield pretty much cover it?  Is anyone from Avast monitoring the forums anymore?

Not sure if it helps, but you could try updating TB to the latest version (78.3.1).

I just tried sending myself a msg and it failed after making the change suggested by Asyn - the result

"Sending of the message failed.
The message could not be sent because the connection to Outgoing server (SMTP) smtp.gmail.com timed out. Try again."

This occurred after setting Mail Shield enabled and scan inbound... & scan outbound... enabled.

If I turn off scan inbound and scan outbound - the msg is sent.

I'll admit I'm a bit frustrated and annoyed.
