Thunderbird-Hilfeforum

Hi folks, I am wondering if there is a way to change the behavior of the pop-up reminder window in Calendar. When I have missed reminders (e.g. a task set for today at 8am and it is now 9am), the task is visible in the reminder window that pops up every time a reminder is active. This is fine. But if there is a past reminder (not resolved), every time I add a new task (or edit a past task) to the calendar, the pop-up reminder window opens and comes to the front. Let me describe the example: I missed (knowingly) a reminder at 8AM. Now, at 9 AM I need to add 3 new tasks to the Calendar. After setting (or copying, editing) each new task, the pop-up reminder window is focused on the front. Can I change this behavior so that the reminder window only pop up when the reminder is due and not in the case a new task is set up or old one edited?

I upgraded to Thunderbird 115.10.0 (x64) earlier today and now the program is no longer closing completely (I've tried using the X at the top right of the window, and I've also tried File menu -> Exit). I first discovered this when I was using CCleaner to clean my temporary items and it asked me if I wanted to close Thunderbird after I had already closed it. I then checked my running processes and there are three Thunderbird processes that remain after the program has supposedy closed (Task Manager screenshot attached).

Any help with this seemingly new bug is greatly appreciated!

Much thanks, -Snipe

I can't use Thunderbird any more. I open an email and I get 7 copies up across the top of the screen. Delete does not get rid of them, and I am up to over 50 at this point. Please contact me directly at [removed phone# from public support forum] when you have fixed this. For reasons I have just outlined, email is not a good way to communicate.

I assume that everyone else is experiencing this disaster.

How do I go about fixing error message regarding Incoming Mail: UID Fetching Failed

I tried support page, but all threads archived. Not sure how to proceed? Be kind too as I'm also pretty old!

I see that there are 9 messages...Tried tools, checked account settings and couldn't find anything.

Your help would be greatly appreciated. Bad day. My sink is stopped up too!

Hello! I am facing the issue with time zone translations. Here is what I do. First, I create event on web-interface of the google calendar. That account is linked to TB's calendar. This calendar has settings for my timezone as in the first screenshot, that is GMT+3 for Kyiv, Ukraine. It is actually GMT+2 + daylight saving hour in effect. Country is also set to Ukraine. Next, my Windows 11 system is set to set time and timezone automatically, region - Ukraine. It displays UTC+2 Helsinki, Kyiv,... I guess it's Windows settings display quirk, because time is correct and WSL console shows

~$ date -R Thu, 18 Apr 2024 18:59:25 +0300

My TB's calendar is set to have system's timezone as in 3rd screenshot.

Now if I see my event in TB calendar, it is placed one hour later, say 9 am event starts at 10. So reminders also come hour later. Also strange thing is that event properties in TB show correct time like 9:00 till 10:40, but for some strange timezone Europe/Zaporozhye, as in 4th picture.

However, if I set TB's calendar manually to Europe/Kiev (which should be Kyiv, but that's another story), then events are shifted hour up to their right place, 9 am. So this is my issue: when I set calendar forcibly to Kyiv timezone, it does translate it right. When I ask calendar to rely on system's timezone, which indeed is also Kyiv, then I get one hour behind.

Old computer: Windows 10 Pro, 64 bit Thunderbird 115.10.0 32-bit (Don't know why it's 32-bit version on a 64-bit computer or whether that's relevant)

The Profiles folder is here (with 5 profiles): C:\Users\<User>\AppData\Roaming\Thunderbird\Profiles

The new computer is Windows 11 Pro, 64-bit I just installed Thunderbird (V115.10.0 (64-bit) on the new computer.

On the new computer, the Profiles folder is here: C:\Users\<User>\AppData\Roaming\Thunderbird\Profiles

I followed the directions here https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer

I basically took the Profiles folder that came with the Thunderbird installation, renamed it (Profiles.orig) and copied in the Profiles folder from the old computer in its place. When I start up Thunderbird, I get this error message:

           Your Thunderbird profile cannon be loaded.  It may be missing or inaccessible

What am I doing wrong? I've updated Thunderbird on the old computer and copied the Profiles folder over to the new computer again. Same result.

Could it be 1. an issue with the user name on the old computer is different than the one I'm using on the new computer? 2. All files on the new computer are set up as local (the user on the old computer started out as a Microsoft user but I made it local so as not to have to use OneDrive).

I'm stumped. Any help will be very much appreciated. If you need any more details I'm happy to provide them.

I used to read my MSN email via Thunderbird. Then one day it told me I had to provide the MSN password to connect. I discovered that I couldn't connect to MSN at all. Had to create a new password for Microsoft, and I know what that is but then they have you do a second thing for the MSN email, and I connect to that but can't see what the password is. How do I find my MSN email password so I can give it to Thunderbird? I've tried various methods, but no luck. Thanks for any help you can provide.

Why is it impossible for Thunderbird to have an option to display the real senders email address instead of just the "fake" display and return address?

I use an addon to add the true address column in version 102, but as usual Mozilla upates disable useful security related updates.

When is Thunderbird going to show this essential true address instead of spending so much time changing the look and feel?

I am stuck with version 102 or another email client until this changes.

Hi. I love Thunderbird! But I cannot use a Gmail account.

It all started when I changed the underlying password for my Gmail account (for routine security). I changed the password too on my Thunderbird client for SMTP and IMAP.

But then it popped up with: https://accounts.google.com/v3/signin/identifier?app_domain=http://localhost& [etc]

it keeps giving me this message:

"400. That’s an error. The server cannot process the request because it is malformed. It should not be retried. That’s all we know."

I've tried to read online what's going on. I've deleted the account and tried to set up again, and closed Thunderbird. It keeps doing this. I've checked Google settings ... nothing untoward. It doesn't have a link to Thunderbird still.

What can I do?

Thanks, Dan

Messages I sent from my iphone are showing up in my inbox marked with a gold star and looking like they came from the recipient, but they werent. Almost like a reminder of an email I sent? - I mistake them for new incoming messages. Why is this happening and how do I make it stop???

See the first two messages in the screen shot.

Hello all

as per subject is there a way to reply directly in the preview window like outlook and not in a new window? I tried to search in options but I can't see if there is a way. The pop up new window is a little annoying.

Thank you :)

Reaching my end with defects in thunderbird. I select items in the inbox/index of the UI and it isn't updating the email view pane.

Sometimes I select in the index, it highlights the message, doesn't update and then 10-15 seconds later, the UI does a big update like it had hung on something, and it just ignores my selection completely and selects whatever it wants. This is crazy.

I'll add I have a "unified folder" and despite the 3 accounts inboxes included from accounts configured to never auto update, IT ALWAYS does updates whenever it wishes. Again, this is crazy. Like it can't be supposed to work like this ?

So: Is this thing single threaded ? Is the "unified" folder functionality mature and does it work properly ? Suggestions or pointers to fix or research/test what I see is just flat out poor performance when clicking stuff in the UI ?

I really can't believe I'm questioning the basics of thunderbird.

Version is Win 10, 115.8.1 (64-bit), udpating now but I'd say I have found the basic performance to have tanked since the bug UI change to "modernize" it. Seems to me, without exact data to support that I have been degrading ever since. No updates I've made in last few months have improved anything.

Really don't want to leave but I'm about to try using it on Mac and Linux to compare and at same time I just configured all this in apple mail for the first time in maybe 10 years. This is something I never ever thought I'd do.

Last thought, I use same accounts, on iPhone (Boxer) and many iPads. I don't see any performance problems there so I'm pretty confident this isn't the mail servers.

I'm unable to send any emails from account on Thunderbird. This just started this week. All send attempts generate this Send Message Error:

Sending of the message failed. An error occurred while sending mail. The mail server responded: Please turn on SMTP Authentication in your mail client. syn-076-088-235-065.res.spectrum.com ([192.168.1.25]) [76.88.235.65]:51343 is not permitted to relay through this server without authentication.. Please check the message recipient

This error for every recipient I typically correspond with. I have my same email account loaded into Outlook on another pc and I can send emails to all recipients without error from Outlook.

Help please.

Using Thunderbird Linux for years on my laptop, it sometimes happens that an error message from Thunderbird pops up (mostly because connection problem when I'm in a train or outside, maybe draft can not be saved or whatever).

I just so happens, that when I'm writing an email exactly at this moment and press space, the error message is gone before I had a chance to read it. I could even accidentally answer (y)es or (n)o to a specific question if I happen to press y or n at that moment when the message pops up.

So, not an everyday problem. For me it's happening like a 2 or 3 times during one year. Not quite sure how it could be solved.

using a Mac Laptop, Email account is Optus, can receive emails ok but cannot send, getting a failure massage.. Any suggestions please?

I send .doc and .pdf files to my customers. When creating the outgoing email message and attach a file, I used to be able to see the file in the preview pane. I can no longer see the preview. Please help. This feature does work for jpg, tiff, and other image files.

I just asked this question a few minutes ago. This is a correction. It's only the font size in my signature that has shrunk since the latest Thunderbird update. The image in the signature is still the same size as it was before the update. I would like to know HOW to make the signature font size the same as the message font size.
