Thunderbird Support Forum

I use Mozilla Thunderbird 115.9.0 (64-bit). I was able to send messages until just recently. Now when I send a message, it just hangs - no error message or anything (these are very short messages). I am able to receive messages just fine and send a message through webmail at cox.net

Please find attached a screenshot of my account settings. Any help would be greatly appreciated.

Thank you very much in advance.

Hi everyone,

I am trying to setup Thunderbird to work with my company Exchange account (have installed TBsync and provider for exchange tbsync). It works well but Thunderbird has created on the server sent/trash/archive/drafts folders instead of using the ones that exists, and thus I can't access my history when I am in Thunderbird.

Is there anyway to parameter this? I couldn't find any, there are only options to store in local or on the folder created by Thunderbird (see picture). Thanks in advance for your answers!

Hi, I have a nextcloud setup at home on my internal network. Whenever I am away from that network, Thunderbird bombards me with error messages because it cannot sync a specific calendar (An error occurred when writing to the calendar Contact birthdays! Please see below for more information.) This is the first calendar on the list of calendars so I think it just happens to be that one that causes the error. What I would like to do is have Thunderbird detect that it isn't on my home wifi and not sync the calendars. Is this possible? Thanks!

Hello. I receive messages, read them and then they disappear. I've been using TB for a long time, but there's a transition from IMAP to POP3, and it's been a mess since then. I DON'T WANT "pop3" :( I want IMAP :( I read opinions where people suggested deleting the .msf folder. I deleted + uninstalled TB. I installed it again, provided data for incoming and outgoing mail. They still disappear :( But I have messages from February in the SENT folder. Messages sent now also disappear. Why?

Using the latest updated version on Windows 11. For some reason, selecting Read Receipt does not currently have any effect! P I don’t often need to use it but when I do, it’s frustrating to learn that it no longer functions. I know I can opt to make it ‘global’ but don’t really want to. All/any help gratefully received. Regards Peter

Thunderbird continues to lose my password for incoming and outgoing mail. Occasionally it works, but I keep getting messages that my password doesn't work / enter new password. When I go to passwords, it does not show the incoming or outgoing servers so I can make sure my password is there. I use Xfinity for my email. It was suggested earlier that it is an Xfinity problem. My Thunderbird email is essentially unuseable. I need it to work!

Trying to delete an email account that is no longer used. System continues to attempt to read from the provider because I cannot remove the account and is delivering error messages every few minutes which is very annoying.

I've gone through Account settings>Remove account>Confirm remove BUT the only active option is Cancel. The Remove and More Info buttons are greyed out.

In the received message pane, unread messages are in a bold font, but, after reading a message, the font does not change back to a normal un bolded font. I have looked at every setting I can think of and I cannot get this to work the way it did in version 102. I am currently on 115.9 ,but, I may revert back to version 102 which worked without any problems. Can you help me resolve this problem?

I have been a TB user for years. Recently, many problems. Today (for the first time) I can't even launch the program. One I got the error "Cannot open XXCOM" where I used XX for letters which I can't remember. Then I tried again and got a breakpoint error: "(0x0000003) occurred in the application at location 0x000000006D809898"

I am a long-time TB user with gmails. No problems in the past. I inadvertently hit send for my reply to a message delivered to me on a no-reply account (Wordpress). A big overlay screen popped up with the heading "sign in with Google" and then "sign in to continue to Thunderbird email"; then "enter email or phone"; and then "next". Clicking next takes you to a new screen that reads "Google 400, the server cannot process the request because it is malformed. It should not be retried. That's all we know."

Meanwhile, TB tries to log on until it times out, ending with small box in lower corner of the screen, "Authentification error" (see third screen shot).

I logged onto my Google account and as far as I can tell that is okay. I've turned off my computer and tried sending emails, but always get the above screens. Seems like I'm caught in a loop and can't cancel out the error message. Is this a TB problem or a Google problem. Help!

Anyone answering this thread should email me at wetteraubruce1@gmail.com. I can read that email address on my laptop.

Hey,

I'm asking my question here because I am not sure whether that is a bug with Thunderbird (as suggested by similar topics found with a quick online search) or with my system.

I am currently using Thunderbird 115.9.0 on an Arch Linux system with kernel Linux 6.8.4-arch1-1 and GNOME 46 with Wayland.

The problem is: The compose message window immediately loses focus when I click at it. Closing the main window doesn't help (or any other open window for that matter). I can still type and some of the buttons still work (tested Save and Send) but I can't edit recipients and I can't close the window (attempting to closes other open windows instead).

Things that were recommended elsewhere and that I tried to no avail: - clearing the cache - updating thunderbird and my system (already up to date) - moving the window to another workspace/closing all other open windows - restarting (duh)

I think this problem is with Thunderbird because I don't experience focusing issues with other programs.

I am also happy to provide additional info if someone wants to write an actual bug report. I was just scared off by the requirements of Bugzilla.

Hope someone can help me, Best,

Maria

Hello, In Thunderbird (Vers. 115.9, OS Linux Zorin OS 17) I can integrate a calendar from a Mailbox.org account as described here(https://kb.mailbox.org/de/privat/adressbuch-und-kalender/caldav-clients-outlook-thunderbird-macos-evolution-kontact/). Everything works fine. If I now want to import a 2nd calendar from another mailbox.org account, this does not work. I can go through the process normally, but the 2nd calendar is not displayed. Does anyone have the same problem? It can't be that Thunderbird is not able to integrate 2 calendars ? Many thanks for your help

I cannot get K9 to accept that I do not have a password verification for my e mail account.When K9 automatically configures my account IMAP and outgoing server it asks for password which I don't have

Clocks went back one hour in Santiago, Chile last week and Thunderbird does not recognise the new time, although Windows (10) does.

The calendar line show the current time to be one hour ahead of the time on Windows; i.e., the Windows time has updated correctly, but the calendar time has not. Adding non-local events to the calendar causes them to be displayed one hour ahead of the correct time.

Changing the calendar setting to use the system timezone, or use America/Santiago has no effect that I can see.

Typing Date() in the error console of Thunderbird gives the correct time, as per Windows.

This also happened in the last time change here in Chile.

How can I fix the Calendar to see the same time as Thunderbird and Windows?

Good afternoon to all.

I use Message Filters to automatically send certain emails to two specific folders upon receipt, based on some defined rules (mainly who the sender is). Yesterday, I accidentally clicked "Run Filters on Folder", and the actions for my filter rules ran on every folder in my account, including my Archive folder. I could not find a way to stop the action once it started, so hundreds of archived emails were pulled out of the Archive folder and repopulated into my two specified folders. In each of these specified folders, I had a handful of emails stored in order to be able to come back to them as reference or to deal with later; I remember what some of these emails were, but I don't necessarily remember all of them, and now they're mixed in with the hundreds of emails that were brought back from the archive.

So, I have two main questions:

1. How can I prevent this from ever happening again? Is there a way that I can tell the message filters that a filter should never be run on archived messages?

2. Is there a way I can "undo"/reverse what happened, so that the previously-archived emails are sent back to the Archive? Or is there at least a way to identify which emails were in the two specified folders before they were inundated with all the messages from the Archive?

Thank you.

'Vanishing Menu BarBar' Mac OS system is set to NEVER hide menu Bar, yet both Thunderbird and Firefox hide the menu bar, they are the only applications I have that do this. the posted solutions DO NOT EXIST in Mac OS 14.4.1. The posted solution says to customize and then go to a menubar drop down, but in both apps there is NO such menu item. There is a menu item for the tool bar, which I have ON, but not for the menubar. So what gives?
