I am using Windows 10 and FireFox as a browser. I am hard wired into my router. I checked to make sure I had internet.

Thunderbird works great for a while then refuses to connect to the Gmail Server. I keep getting the following message. I was able to save the message.

I can't figure out why it is so random. Thanks Jan

Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp.gmail.com failed. The server may be unavailable or is refusing Outgoing server (SMTP) connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.

Your server settings look good.

Try to start *Windows* in safe mode with networking enabled. - Win10 http://windows.microsoft.com/en-us/windows-10/change-startup-settings-in-windows-10#v1h=tab01

Still in Windows safe mode, start Thunderbird in safe mode. - https://support.mozilla.org/en-US/kb/safe-mode

Does the problem go away?

I went into TB safe mode (not Windows) and that seemed to fix the problem. Will I have to do that every time I restart Thunderbird?

Does it 'seemed to fix the problem', or does it fix the problem? Please also try Windows in safe mode.

What is your anti-virus software?

No, this is for troubleshooting only.
