I recently had an issue where my email password changed on another client, but Thunderbird did not prompt me for a new password. After two days, my account was still frozen with no new emails on Thunderbird, although they were updating on other clients. The Mozilla help on the issue said to go to "Options." There is no "Options" option in my Thunderbird, not in the top menu, not under server settings, not under Account settings, not under Tools. My version of Thunderbird is 115.11.0 (64-bit), running on Ubuntu Linux 22.04 LTS. Maybe the issue of no "Options" option is specific to this particular incantation. Here's what I did to force Thunderbird to prompt me for a new password. I selected "Server Settings" below the email address in the left pane. I changed the Server Name to one that is incorrect. When I migrated away from that textbox, Thunderbird raised a popup window that it had to restart. I let it restart, and when it came back up, it prompted me for a new password. I now input my correct password for the email address. It came back a few moments later that the password was incorrect, asking me to enter a new password. Well, it's the server URL that's incorrect, not the password. I cancelled the popup window, then changed the the server name back to the correct one. When I migrated away from that textbox, Thunderbird again raised a popup window that said it had to restart. I let it restart, and when it came back up, everything was fine, and my two days of undelivered emails came through immediately. I hope this can help others who are bewildered by the lack of an "Options" option on their version of Thunderbird.
