Hello, since recently I am no longer able to use my Google Calendars in Thunderbird. Environment: - Thunderbird 153.4.0esr, 64-bit - Windows11 - Google Calendar / CalDAV - No “Provider for Google Calendar” add-on installed Problem: My Google calendars previously worked normally in Thunderbird. Recently Thunderbird started showing that the calendar was temporarily unavailable, and attempts to modify events resulted in: MODIFICATION_FAILED I therefore removed all Google calendars from Thunderbird and tried to add them again. When adding the calendar using: https://calendar.google.com Thunderbird opens the Google OAuth login. I can log in successfully with the correct Google account and complete the authentication process. However, afterwards Thunderbird reports: “The entered credentials were rejected. Please check the settings above.” I have already tried the following several times: - removed all stored Google / OAuth credentials from Thunderbird - restarted Thunderbird - verified that cookies are enabled - verified that no VPN is active - tested the Google Calendar successfully in the browser - tried the direct CalDAV endpoint at apidata.googleusercontent.com - confirmed that the “Provider for Google Calendar” extension is not installed The Google account and Calendar itself work normally in the browser. The issue therefore appears to be related to Thunderbird’s Google Calendar OAuth / CalDAV authentication. Could you please confirm whether this is a known issue in Thunderbird 153.4.0esr and whether there is a workaround or fix planned? Thank you.

Hello, i use Thunderbird on two desktop-pc and one mobile phone for my e-mail account. Since two days it is not possible anymore to place attachments on one of the desktop pc. The other devices work correctly. What can I do? Best regards, Andreas

Email being stopped by avast (inbound. att.net ) mailshield. Certificate revoked not expired and can not be updated. Location: other people directory. Thank you David. [redacted] @hotmail.com

Yesterday, Oct 6, at 3:20 pm, tbird was unable to download messages from my att server. The error message is "The certificate for inbound.att.net does not come from a trusted source". Nothing that I know of has changed when I look at the account settings.

Do I need to contact Att/Yahoo? If so, how can I describe what to tell them, as I have no knowledge of certificates and how they work (or don't work).

Greetings,

I've lost the ability to receive e-mail, Suddenly Thunderbird just quits on me with no warning. Apparently I can still send mail but cannot receive. This is the second time this has happened to me in as many months. How do I fix it? How do I prevent it?

Thanx

Windows 11, Dell laptop, Thunderbird Meadow 153.4.0, yahoo mail configured as pop3 (i like to keep messages on my laptop). I was having trouble with mail getting "stuck" on downloading the past week or two, sporadically. It would load maybe 13 of 90, or 4 of 64, or whatever, then I'd get a "Connection to server timed out" message. I went online to the yahoo mail site to look for some offensive email that was trying to load and delete it; deleted about 50 of the messages that would've been sent to Thunderbird, then tried again. Did this a few times. Today it started where it wouldn't even load 1 of 34, or 1 of 60, or 1 of 96 as the day went on, would just time out on trying to load the first one.

Tried changing to IMAP temporarily, didn't help. Switched back. Didn't help. (Restarting each time I'd change this). Finally resorted to deleting the account (and all of my folders and filters! argghhh!) and re-adding it. Let Thunderbird automatically configure it for pop3. I did change the setting to not have it delete the messages on the yahoo mail server once loaded into Thunderbird.

Seemed to help, and it immediately tried to download the 3800+ messages that I've saved on the yahoo mail server. Only got to 1900, then stopped and timed out.

When I ask it to download new messages, it's back to the same thing - tries loading 1 of now 2007 or something, and can't get past 1. Times out.

Notice the version number above; it was much older, and I've since updated it 4 times to bring it up to where it is now where no additional updates are available at the moment. So as much as I'd like to blame it on an update, I hadn't had any automatic updates for a long time, so it wasn't that, and getting the updates now hasn't helped either.

Any suggestions?

I've read that I can create several Thunderbird profiles and load my desired Profile to startup and use the Profile Manager to switch profiles. I'm guessing that I can only load one profile into Thunderbird at a time (?).

And if I wanted to check emails from another profile I'd have to close or switch or somehow unload the current profile(?).

It would seem to me if it were possible to load more than one profile at a time, then if two profiles had the exact same mailbox account, it would cause problems(?).

Appreciate any input from those with experience in this.

How can I get rid of that horrible bug of Thunderbird prompting me for my login credentials. Already tried the following: re-adding my Email account, reinstalling Thunderbird from scratch. Nothing has worked.

I'm trying to add an email account to Thunderbird that (seems to) require Oauth2 authentication, but it keeps opening the wrong provider in the Firefox window that it launches. The email account is a professional G-Suite address, but it always opens login.microsoft.com instead.

I've checked the MX record for the domain and it correctly lists Google servers, and my laptop was able to authenticate to the correct destination just fine. I have used my desktop for work before, which is all handled through Microsoft accounts, so I suspect that there's some kind of locally cached data which is identifying O365 as the provider, but I can't find any relevant settings or documentation from Firefox. I also cannot find any settings or controls for the Oauth provider in Thunderbird in order to force a Google workflow.

ever since last update... can't send emails

I changed POP3 email password to an app password and Thunderbird would not recognize it even though I updated in Security. I was told to delete the Thunderbird account then set it back up which I did--I did not check the box to delete files. Finally the new account was able to bring in new emails (POP3) but the old folders/emails are not there.

I read that I should go to %appdata%, roaming, Thunderbird but the dates are from years ago--do I go further to find my data or is there another path or something else I should do?

Unless they were backed up somewhere within Thunderbird, I don't think I have any backup.

Can you please help? Thank you.
