I thought there might be a problem with Thunderbird 133.0, so I attempted to install version 130 over it. I was told it was incompatible with version 133.0, so I uninstalled version 133.0 and installed version 130.

Since then, Lightning Calendar has been missing, even when I reinstalled version 133.0. The Events and Tasks tab is missing. Calendar does not appear in Add-ons and Themes. There is no trace of it anywhere. I uninstalled Tbird, deleted all of the folders for it and reinstalled Tbird, again. No luck.

Recently forced to update MAC OS to Big Sur, then Thunderbird stopped connecting. Thunderbird asks for a password that i enter correctly (works when directly logging into Gandi) but will not accept. No option on entering user name, just password. Contact@kencorm.org

Also, I payed for years and I'm getting pay or account will close 25 Jan 2025...

Thank you, Ken Cormier

Thunderbird won't remember where it was last time (windows 10 and 11). Every time I open it, it has shifted and resized a bit from the last time. It's not one monitor to another or even the other side of one screen, but it's always slightly higher or lower, slightly smaller or larger... It's just driving me nuts because everything else is perfectly positioned. Note that I am using fancy zones to do this placement, but everything else works fine.

Using thunderbird to connect to the mail server outlook.office365.com with imap gives the message "user is authenticated but not connected" . I have 2 accounts on this server and one works fine and the other gives this message. This occurs on both Windows 10 and Windows 11. Latest version of Thunderbird is being used. Any help would be appreciated.

I had Thunderbird and switched to Outlook when I purchased Office. I liked Thunderbird better so I switched back. I exported my Outlook calendar and imported it to Thunderbird. The calendar works, no problem.

The problem is that when I open Thunderbird and select the calendar for the first time Thunderbird hangs. If I check the message indicates that Thunderbird is busy. After a period of time everything works. The only time this occurs is when I start Thunderbird and select the calendar for the first time. Can you tell me why?

If it makes any difference when I imported the calendar I did not realize how Thunderbird worked and I imported it creating a new calendar with the name of the imported file. I had a Home calendar with nothing in it and my imported calendar. I decided to export the calendar that was created during the import. I then imported that file to the Home calendar and deleted the original imported calendar.

My wife decided to add our son to our You Tube TV. She is not the greatest with computer. I have been unable to access my Thunderbird emails since Saturday. When I sign in I am asked to enter my email address and I get a 404 error message. I'll attach the messages I have received. Have to talk on phone if that is OK.
