I have TB 68.5.0. One of my gmail accounts refuses to send out emails. I checked settings, which seem to be ok just as other gmail accounts that are working .

Also, as I noted, none of gmail accounts receive or send out emails now.

Strange. Suddenly my gmail accounts started working fine in TB. (Is this because Avast removal? TB asked about allowing TB to access gmail, or something for some accounts, not all accounts. ) except: at japaneselinguist1@gmail.com, incoming emails go to Important folder, rather than Inbox. How to prevent this from happening? I want to see all incoming emails in Inbox first. (Maybe this is the account TB did not ask to access gmail. Not sure) any comment?

Is Windows enough to protect?

Windows Defender is all you need.

How to create an exception in Windows Defender?

Look through the Defender options. There aren't that many. Then add the Thunderbird profile folder as an exception as adviced earlier. https://support.mozilla.org/en-US/questions/1280399#answer-1292475

Most likely yes.

TB asked about allowing TB to access gmail, or something for some accounts, not all accounts. )

That's for those were you changed the Authentication method to OAuth2.

at ...@gmail.com, incoming emails go to Important folder, rather than Inbox.

I suppose it's something you can turn off in your Google settings (not Thunderbird).

The same problem started again with Japaneselinguist2@gmail.com. It does not receive or send out emails at TB. I did nto change any setting.

On webmail side it works fine.

See attached screenshots of the message and settings.

Please post again your Troubleshooting Information. At the top right of the Thunderbird window, click the menu button , then select Help > Troubleshooting Information. Press the "Copy text to clipboard button" and paste the information into your reply.

Also, indicate which account is the troubled one.

Did you create an exception for the Thunderbird profile folder in your anti-virus software?

You do, and this has been explained to you before. As per your Troubleshooting Information:

Security Software Type: Name Antivirus: Windows Defender Antivirus

You haven't answered the question whether you created an exception in Windows Defender for the Thunderbird profile folder, so I'll take that as a 'no'. You'll have to fix that.

If you're unsure what to do, please ask in a Microsoft forum.

In Defender, I could add TB as an "Allowed App". Also, I enabled TB at Inbound. See screenshots.

Are these what you meant? I could not find a location in Defender to specify TB Profile. The profile is a folder and not an app.

By my count, you have 6 gmail accounts: 3,11,12,13,14,15. You will have to figure out which one is for japaneselinguist2. Set the authentication for all incoming gmail servers to OAuth2, and the same for all 6 smtp servers. You must have one smtp server for each account, with the same User Name. Select an account in the left pane of Tools/Account Settings, then click Edit SMTP server in the right pane to check that the User Name is the same as for the incoming account.

This is the Windows firewall, and no one suggested to you to mess with that. I'd strongly suggest you reverse any Firewall changes you made wrt Thunderbird. What we're talking about is Windows Defender anti-virus. https://answers.microsoft.com/en-us/protect/forum/protect_defender-protect_scanning/how-to-exclude-a-filefolder-from-windows-defender/f32ee18f-a012-4f02-8611-0737570e8eee

This article was written for Win8. I don't think anything fundamentally changed since. In case you need more specific instructions for your version of Windows, I suppose you know how to use Google, or check with Microsoft.

1. I have found a Gmail account not using 0Auth2 and have corrected it. 2. I have reset Defender settings back. 3. Also, I set Defender Virus Exclusion for TB profile folder. See attached.

The problem still persisted.

I found multiple PWs are stored in TB for the same Gmail accounts. I deleted them, and re-input them when asked. This seemed to have solved the problem.

There does appear to be some issues with changing passwords with gmail at the moment, there is an active bug report. But deleting passwords stored in Thunderbird appears to be an effective work around.

Largely resolved, but I notice sometimes emails do not go out and struggle, and I close TB and restart, it goes out. Why does this happen? Anyway to solve this? Or it is a nature of TB?
