Hi everyone,

I'm having trouble with my Thunderbird app (version 115.11.1) on macOS. I'm trying to add my Google accounts, but after I attempt to connect them, I receive the following warning message: "Unable to log in at server. Probably wrong configuration, username or password."

I've checked the configuration multiple times to ensure it's correct. Here are the settings I'm using for Gmail:

Incoming Server (IMAP): Server Name: imap.gmail.com Port: 993 Connection Security: SSL/TLS Authentication Method: OAuth2 Username: [my email address]

Outgoing Server (SMTP): Server Name: smtp.gmail.com Port: 465 Connection Security: SSL/TLS Authentication Method: OAuth2 Username: [my email address]

I've also emptied all saved passwords and allowed cookies from sites without any exceptions. Is the version of Thunderbird I have still incompatible with Gmail? Or is there another issue that I might be missing?

Thanks for your help!

Everything looks correct, but it's possible you have an antivirus or some other app such as VPN interfering. Try running OS X in safe mode to bypass startup apps and see if that helps.
