Gmail Account

Hi Folks,
I get this when trying to send an email using my Gmail account in Thunderbird portable (I use POP3).
Firefox Forums are unable to explain it.

Did you check your settings? Are you sure that you have the correct name and password on Thunderbird?

Hi richc46,
I have been using TB for a while, this is its latest problem just started today.

I use GMail, too, but not Thunderbird. What I would do, if I had the problem.
Boot the computer, you would be surprised how many problems that can solve.
If that does not work, remove the GMail account from Thunderbird, boot and then supply the necessary information for GMail. Keep us posted.

Hi:

Hmm, that's odd.

I'm on my Win10 box at the moment, but I cannot reproduce your issue with Gmail in Thunderbird 45.3.0 (full, installed version, not portable), POP3.

Outgoing messages working fine.

FWIW, there is no official Thunderbird "portable".
I assume you are using this?

Mozilla Thunderbird, Portable Edition | PortableApps.com - Portable software for USB, portable and cloud drives

Having said that, what happens when you try it from Mozilla Safe Mode (not the same thing as Windows Safe Mode)?
