Thunderbird Community Forum

My Thunderbird installation (159.0/Windows11) has evidently just updated, and my Calendar tab is suddenly a complete blank space. There's a support article here that appears to discuss exactly this situation, and gives precise steps for getting into "Config Editor" in Advanced Settings, entering a long search string, and issuing a Reset command. (Mail and contacts are just fine.)

Which I tried...

But there is no "Config Editor" button in the dialog I get when clicking Advanced Settings at the bottom of the Settings tab, only a mostly blank screen with no list of settings and a dialog box in which one can enter text (with options for "Boolean", "Number" and "String"). And entering the search string given in the support article produces, with a bit of finagling, a toggle that will change its setting from True to False and back again (and a trash-bin icon that offers to delete it), but neither "True" nor "False" produces any instance of a "Lightning" extension in my list of extensions (which is short and uncomplicated), so (a) I can't delete the extension as instructed, because it's not there, and (b) restarting Thunderbird only continues to give me the unhelpfully blank Calendar tab. (And I do mean "blank" here - there isn't even an empty calendar grid on that tab at this point.)

I *think* the article is probably right that my data is still there (I can see .ics files with current dates in File Explorer), but at this point I can't get at it and can't seem to get the interface unstuck.

This just started yesterday: When I open thunderbird my inbox does not show up unless there is a new unread email in it. Also my previously set display columns and tool bar all have to be reset each time I open Thunderbird.

Lately I have noticed that when I delete an email it Is not going into my trash folder. I am using version 159.0 (64-bit). Any assistance would be greatly appreciated also I am using an IMAP server

My profile contains 30 years of work emails which I sort as received into organized folders, stored on my computer. This archive is used frequently to search re projects, correspondence.

My email provider is shutting down. I have already set up my own POP3 server, with new email address.

I'm using webmail until I'm confident I can make the transition w/o screwing up! [Had one storage melt-down which required weeks of work to recover folders from a backup. Once burned, twice shy.]

>> How do I set up/alter Thunderbird profile and/or folders so that emails coming in to NEW address go into the existing inbox/profile folder(s)?

I want to be able to search both NEW and archival emails w/o having to switch between folders/accounts/profiles.

Bonus Q: The old provider is shutting down 12/15/26. While my correspondents adjust to my new email address, being able to see/process emails sent to the old address w/o changing profiles, etc., would be great.

Thanks!!

My Thunderbird calendar is frozen. When I click on November arrow the calendar does not move to December. SAme for year. I have the calendar set as weekly however the screen does not show the days. The odd time that I get the current week to show I can not enter a task/reminder. Please help

My two Optimum email accounts (POP3) stopped sending messages. See attached error message. They are still working on a different computer with the exact same settings and Thunderbird version (Windows 10 on both too). I also have Outlook and Gmail accounts all still sending fine. Sending from troubleshooting mode and clearing the startup cache didn't help. Any clues what I can try?

I followed the instructions in the aritcle on the search page and it still didn't work. I worked with Geek Squad. They completely did all kinds of different settings and they all failed. When I click the test button, it says it connects successfully.

It tells me to retry or update the password.

I am absolutley typing in the correct password.

Mt T/B was working ok, then for no apparent reason I can not get my emails nor sent them. It tells me to go to configuration settings. When I get to settings and look for passwords. and view passwords, my main email address is not there; others are, along with their passwords

Love Thunderbird - thanks!

Can't seem to find what folder an email is in doing a search. The list of results doesn't show it and can't see it in the email. Maybe missing something. I sort emails by folders so not knowing the folder makes it hard to find what folder it is in (such as I may want to move that email).

I have 5 accounts. Since the update when I start Thunderbird, some accounts appear in name only with no folders. Then, if I exit then enter again the tabs may appear and the Thunderbird sets about resyncing them all. Help please.

I keep getting a pop-up message from https://s1021.use1.mysecurecloudhost.com requesting my username and password for one of my accounts. I enter both, I still have access to my accounts, and still the pop-up recurs. How do I resolve this??

Latest update (I reinstalled rather than update) left several aspects of TB operating poorly, esp calendar and address autofill. Calendar either doesn't display or displays empty; I tried posted fix of changing config and rebooting, didn't help. Address autofill simply stopped working, though all my address book directories are intact. Thanks in advance for any advice.

I am trying to get my Address Book(s) off an old PC that barely has any resolution. I cannot locate any MAB files, only SQLITE files (abook, etc.). What is the file that the address book is found in?

When I open thunderbird, the inbox say "No Messages". I then go to "File" and then "Get new messages for" account. Some times it takes several tries before all my messages (New and Old) appear in my inbox. Also, each time I open Thunderbird, I have to reset my columns.
