If you turn on "Show Timezones" in the New Event window, then close it, and open a New Event window again, the time zones will be shown, but the option will not be checked in the settings, checking it now will hide it instead

Hello,

I have been using Thunderbird only occasionally for backing up Google emails after which I delete the emails from Google. I am thinking of using Thunderbird permanently but there are things I'm not sure about.

1). Does Thunderbird automatically integrate Google Take Out mbox files automatically into one email list? When I start Thunderbird, I see files that I have uploaded to Thunderbird (on two occasions in the past and these were mbox files from Google Take Out) but these files are empty. (screenshot attached). When I select the "all mail" folder all of the mails saved since 2005 appear to be there.

2). Does Thunderbird save attachments or only the emails themselves?

I would be grateful for some help so that I can optimise my working with Thunderbird.

Best wishes

DanZ

When I go to set a custom time for when an event's reminder will happen, it doesn't matter what date or time I put, when I click OK, it sets the date to be today, and the time to the next hour, if I use the date and time picker dropdown thing (clicking the arrow instead of typing it in), the date does set correctly, but the time is impossible to set even like that

Hi, I’m having a recurring UI issue in Thunderbird with the toolbar above the message preview pane.

After some time of using Thunderbird, the area between the message list and the message preview becomes visually corrupted. The toolbar where the Reply / Reply All / Forward buttons should appear either disappears completely or turns into a broken/glitched gray bar.

I attached a screenshot showing the problem.

What I already tried:

Restarting Thunderbird Starting in Troubleshoot Mode Disabling all add-ons Resetting UI/customization settings

These actions help only temporarily. After some time, the issue comes back again.

Additional info:

Windows 11 64-bit Latest Thunderbird version The problem seems random, but happens multiple times per day It affects usability because I lose quick access to reply buttons and message actions

Has anyone experienced something similar or knows what may cause this? Humanity invented email clients 50 years ago and somehow we’re still fighting disappearing buttons like it’s experimental Soviet software. Beautiful continuity of civilization.

Thanks.

Hi, I use my Thunderbird installation as a feed reader for RSS. Unfortunately, there are two feeds which aren't updated any more. I can't find an error. The feed is OK, I checked the XML file - the new entries are in the feed. The same feed works with a different feed reader. I already deleted the feed and added it again to Thunderbird. That didn't help. I don't know how to find the error. One of the not working RSS feeds is this one: https://mastodon.social/@islieb.rss

When I execute "right click -> Get Messages" on the feed, nothing happens. No error message... What can I do to find the error?

I'm running Fedora Linux 43, Workstation Edition; Thunderbird 140.10.2esr from Flathub. Everything's up to date.

Thanks, Simon

For two days I'm having intermittent "hanging" when I'm typing a document or letter in Thunderbird. It has just dont that for the 2nd time in less than 10 minutes. Don't know what's happening but it's very frustrating. Am not having any other computer problems. Am running Windows 11 which is automatically updated by Windows. I think Thunderbird is the most current version too. Help please anyone! It does say "(Not Responding) at the very top of the page.

I have tried multiple times to setup a new Outlook email to Thunderbird. I already have one setup and that's fine, but when trying to connect my new email account I keep getting the error

exchange auth error

I've tried everything to fix it.

The setup configuration all goes well, but then connection just won't happen. I've checked in Outlook and I have given Thunderbird permission but still it won't work.

I have the latest Thunderbird on my laptop. I have turned off the hub, but it still appears when I add an account. Sigh!

Please help!

In Firefox, to send an email, you click on the NEW EMAIL button in the tool bar and the email app appears. When you click on the TO button to add email addresses, the ADD RECIPIENT page appears and a list of people and their email addresses normally appear.

THERE IS NO LIST OF PEOPLE AND EMAIL ADDRESSES. They have been moved to the PEOPLE folder on the left side tool bar below the top MAIL icon. The email list in the PEOPLE folder is still in tact

My question is how do I correct this error which appears to have happened during an update.

One would think if you highlight/select the PEOPLE email list it could be moved back to the ADD RECIPIENT list/folder but that does not appear to be possible.

What is the solution????????

I'm using TB 150.0.2 on a Mac with the latest update of MacOS.

I just deleted all of my archived emails, thinking it was stuff that I had sent to trash. I.e. I deleted all archives, then emptied trash. Only after I did that did I realize that I had deleted things I want to save.

I'm pretty sure there's no way to undo emptying the trash, but I use Time Machine to back up. If I open time machine and go to the most recent back-up, I should be able to get everything back, right?

What folder (or folders) should I restore from a Time Machine back-up?

I keep my mail (both sent and received) in local mail folders. My server is gmail, and sent mail is put in gmail's sent folder by default. Every few months, I copy those messages to a local folder, and after I back them up, I delete the server copy.

What to my dismay, I discovered today that only the message headers, and not the messages were present in the local folder, though they had been when downloaded. Looking at the file sizes, I found the sent file to be 0 Kb, and sent.msf 255 Kb, when sent should have been around 60 Kb long.

I have been able to restore the messages from backup (whew!), but I have no idea how then sent file was wiped out. I know I did not do it.

Has anyone else had this happen? Is there a preventive measure I should take?

I use Thunderbird and received a message about an update which I allowed. I went to another app and when I checked Thunderbird all of my data is gone. The only folder Mozilla Thunderbird folder reads: tobedeleted. It is empty. All of the data is gone. Is there a way to retrieve it? PD - [edited from public] @gmail.com. My desktop runs Windows 10 only.

Mail filters for custom headers like List-Unsubscribe, Authentication-Results or Received-SPF copying messages from IMAP accounts to Local Folders do not work on the Yahoo! IMAP account. For example:

filter1.jpg: name="_Inbox2: List-Unsubscribe <https" enabled="yes" type="17" action="Copy to folder" actionValue="mailbox://nobody@Local%20Folders/Inbox/_Inbox2" action="Stop execution" condition="OR (\"list-unsubscribe\",contains,<https)" (should copy messages from IMAP folders to _Inbox 2 on Local Folders)

filter2.jpg: name="Spam: Authentication-Results dkim=unknown | Received-SPF fail | X-Antivirus-Status Infected" enabled="yes" type="17" action="Copy to folder" actionValue="mailbox://nobody@Local%20Folders/Junk" action="Stop execution" condition="OR (\"authentication-results\",contains,dkim=unknown) OR (\"authentication-results\",contains,dkim=perm_fail) OR (\"authentication-results\",contains,dkim=none) OR (\"received-spf\",begins with,fail) OR (\"received-spf\",begins with,softfail) OR (\"received-spf\",begins with,none) OR (\"x-antivirus-status\",is,Infected)" (should copy messages from IMAP folders to _Inbox 2 on Local Folders)

But filter3.jpg works well: name="Inbox" enabled="yes" type="17" action="Copy to folder" actionValue="mailbox://nobody@Local%20Folders/Inbox" condition="OR (subject,doesn't contain,t[k\6iq69pd+}'cr)" (copies all remaining messages from IMAP folders to Inbox on Local Folders)

(the snippets above are fragments of the msgFilterRules.dat file)

Filters1 and 2 work well on other IMAP accouns, like for example wp.pl. So this is about Yahoo or something is corrupted. My question is, what wrong is here ? And by the way - how to create filter copying all messages from IMAP to Local Folders ? Is better way then filter3 looking for random string in the subject or somewhere else ? Thank you.

How do I import *.ICS file in a reasonable amount of time. I have appointments in an ics file of less than 1 K in size, typically 700 - 800 bytes in size and they take HOURS to import and do not connect properly then to allow editing the appointment. This is from Baylor Scott and White, a major hospital system in Texas. If there is a problem with the imported file structure, please point me to the correct file structure. I like Thunderbird, but this part of the calendar is very frustrating. Clarence

Hi,

I have been using Thunderbird as my preferred email client since around 2004 on Linux, macOS and Windows.

I am current running Thunderbird 150.0.2 64-bit on macOS Tahoe 26.5 ( Intel ).

When I attempt to create a new 'Folder' or 'Sub Folder' on either an iMAP account or, more importantly, my 'Local Folder' the displayed dialogue box is sized incorrectly and I am unable to complete the action.

Specifically I can type into the 'Name' text box and see the 'Create as a subfolder of" drop down dialogue but the two buttons below are barely visible and I cannot select either with my mouse. Nor can I resize the dialogue box itself [ make larger ] to enable to be select either button.

I can use the <TAB> key to cycle thorough the various items and the <RETURN> key to select an option.

I have attached a sample image of the issue.

Thanks.

I have everything I need from my old machine except my e-mail filters. If I copy the whole profile I will lose all of the sent messages and saved messages I have generated since I got Thunderbird up and running on my new machine.
