I am trying to migrate from Mailspring to Thunderbird, yet have problems with adding my Google/Gmail accounts.
When I try to add a new account with my email and password, Thunderbird detects the IMAP details as follows:
INCOMING SERVER
Protocol: IMAP
Hostname: imap.gmail.com
Port: 993
Connection security: SSL/TLS
Authentication method: OAuth2
Username: <my email>
OUTGOING SERVER
Hostname: smtp.gmail.com
Port: 465
Connection security: SSL/TLS
Authentication method: OAuth2
Username: <my email>
When I then try to connect, I get the Google sign in popup, where I re-enter my password and grant the access via 2FA.
Then, the screen to give Thunderbird read/write permissions for mail, calendar, etc. appears, I click "Allow", the popup closes and Thunderbird tells me: "Unable to log in at server. Probably wrong configuration, username or password."
I have checked other help articles; cookies are allowed, Thunderbird has no stored passwords for Google/Gmail, I have no overly protective antivirus software installed (only Windows Defender), I tried it with/without my VPN off.
I saw older articles mention allowing unsecure apps, yet this has been deprecated by Google in 2022 (I also tried "Password only" instead of "OAuth2", didn't work).
I also never got an email from Google that a sign-in request was blocked (only the typical "Did you just sign in?").
Other (non-Google) accounts work fine in Thunderbird, and I only installed it today (so there should be no updates), while another Gmail account of mine doesn't work, either.
I am out of ideas what I could try to get my accounts to work... Can anyone help me?
