I occasionally get a Authentication Failed to Server (Outlook.com) and when it occurs it continues for 1-5 minutes then goes away again.

Is there any error logging proceedure that I can set up to see what the exact issue is?

I've tried running a parallel alternative email client (eM Client) and that doesn't seem to suffer in the same way, but I much prefer Thunderbird so would like to find out what the problem is.

With about 60G of accumulated e-mail in several Microsoft accounts, I moved all accounts into T-bird and put most in local folders. This somehow became over 600G in size. Everything works and compacting seems to be getting done since it's been working some weeks now. Yet this ten-fold increase in size is unwieldy and very difficult to backup. Perhaps related, I notice that M'soft's "new" free Outlook app is present and perhaps running on this computer. And all the e-mails I send from my main Hotmail account are listed twice in the T-bird sent folder. About half of the times I start T-bird, I get a message saying that login to server outlook.office365.com with username xxxxxxxx@hotmail.com failed; the other accounts never do this. T-bird offers to retry, but that usually ends with a repeat of the same message. I've learned that if I let it open, with time, the e-mails do appear, though I don't know how or why. I've also been using Libreoffice successfully for months now though I doubt that anything to do with this. T-bird nicely solved the original e-mail oversize problem I had with Microsoft's size limitations and I'd appreciate advice on how to deal with what's happening.

Hello,

I am new to Thunderbird and need help with configuring the 'Copies & Folders' tab in Thunderbird 115.12.2 (32 bit) running on Windows 10.

Background: I have just set up a pop3 account to download and locally store all incoming messages to my inbox and also to keep a copy of those messages on the server.

I want to store all sent messages for that pop3 account locally too, in a 'sent' folder.

Questions: 1. If I have more than one pop3 account set up like this, do I: (a) set up a separate 'sent' folder for each of those accounts; or (b) set up one 'sent' folder containing sent messages for all pop3 accounts, or (c) is it personal choice?

2. How do I set up: (a) a separate 'sent' folder for every pop3 account? (b) a single 'sent' folder for all pop3 accounts?

3. Can I keep a copy of all sent messages on the folder in addition to storing the locally; and if so how do I configure this?

4. How do I set up the Drafts & Templates section for the above scenario? My preference here would be to have one drafts folder for all pop3 accounts. I don't use templates.

5. If I uncheck the 'keep message archives in' check box, will that turn off automatic archiving and keep all incoming pop3 messages in the inbox?

6. Is there an up to date manual for Thunderbird? I can't find one.

Many thanks for your help with this.

I'm running Windows 10 Pro (64-bit). I have two different versions of Thunderbird installed on my system; one is installed in Program Files (64-bit version 125.0.0.0 dated 04/23/2024—old version) and the other is installed in Program Files (x86) (64-bit version 115.12.2.0 dated 06/25/2024—the current version). The shortcut icon on my desktop (which I never use) runs the older version located in the Program Files folder while the shortcut icon on my taskbar (and also the one in my Start menu) runs the updated version located in the Program Files (x86) folder.

As an aside, there are 21 .dll files in the Program Files (x86) folder (all starting with api-ms-win and dated 09/27/2023) while none of those files are in the Program Files folder.

FYI, I have been using Thunderbird on this PC for almost five years.

How do I fix this problem so that I have only the current version of Thunderbird run from the proper folder, Program Files?

I have a <something> that creates a daily sunrise and sunset entry time in my diary. It isn't an addon as far as I can see. It's not a prewritten list, but seems to create its entries dynamically when I first look ahead to a date- filling all the days with the correct sunrise and sunset times. The normal reoccurring event options don't appear when I delete one. i.e. doesn't offer me the option to delete all the events. I have no idea what I did to set this up ( it must have seemed a good idea at a time). I can not see any subscription that would account for it. I've checked all my accounts on my devices. Thunderbird/Betterbird on my main PCs and Outlook.com on my iPhone just in case I brought it in to TB that way ( which seems unlikely). Nothing. Clearly something is working away generating new sunrise and sunset times to display in TB. But I can't find any way to kill it off. I must have found a sunrise/sunset app that does this, but I have no idea how or where. Any suggestions. Either where it might be hiding in TB or where I can track it down and look for instructions.

I have accounts for my husband, sister and daughter as well as myself. Lately when I try to access my emails I keep getting messages to enter the passwords for these accounts. I have never had to do this before. I don't have passwords for them and don't even really know how to do this.

Also my emails are very slow. I was waiting for a link to a podcast and the email with the code took a little over five hours after the podcast before I received it. This has never happened before.

Help. Gail

Trying to all threads to come up when I click on a new email as a default. Already did this:- settings>general - scroll down to config editor - enter mailnews.default_view_flags and change value to 0. Does not work!

I have various multi-members set up on TB. Most of the time, I use them just as they are, but on occasion, I would like see the members of the list displayed in the "TO" field of the email, so I can delete one or two of them from a specific email. Is there a way to do this?

In Windows Live Mail, for example, clicking on the name of the list would display the members. This doesn't work in TB. Is there a similar function?

We have recently moved to a new mail server. We currently have about 20 Thunderbird email clients on Windows in an office location and a macOS home machine. On all machines email is configured to use IMAP on hostname.com port 993 SSL/TLS with Normal Password and SMTP on hostname.com port 465 SSL/TLS with Normal Password.

The home machine is working 100% with no issues, it does have a much faster and lower latency internet connection than the office machines.

Many of the office machines are experiencing intermitent SMTP error messages when sending, intermitent, "unable to save mail in the Sent folder of the Inbox", messages and intermitent unable to move messages between folders.

I have checked and double checked the settings on affected machines - however, I believe a settings issue would result in nothing working, not intermitent functionality. Plus all is working fine on the home machine with the same settings (different OS, but ports and security settings all dictated by server).

With one client behaving properly, the server likwise behaving properly when addressed by the working client and the intermitent nature of the problems we are finding, I suspect we have some sort of network issue. Somthing timing out or a firewall/AV software causing a delay.

I have increased mailnews.tcptimeout on affected machines to 250 based on a forum article but this has had no effect (No idea of units here but if it is seconde then I am not supprised - the SMTP errors, when they happen are almost instantanious).

Any ideas on how to trobleshoot this problem further - The problem seems to get worse through the day, although that may just be peoples tollerance of an intermitent issue going down.

When I receive junk email, Thunderbird shows mail received (for example 10 emails) there are ...again for example 3 in my inbox and the other 7 are nowhere to be found. Not in junk and not in trash. I am concerned that there might be some emails that are not junk that I am not able to get. I would like to be able to review the junk folder prior to deletion. What setting options do I need to change to make this happen? I am using pop email... Thanks!!

Hello,

When the primary password window opens and I click Cancel, can that window close AND can it prevent Thunderbird from opening?

Example: what if I bring my pc to a repair shop and they open thunderbird and click Cancel on the primary password window. They can See my previously viewed email. I do not want them to see those. Clicking Cancel AND closing Thunderbird would prevent them from seeing emails.

Could this be a future enhancement?

Thanks

Jim

I am running version 115.12.2 (64-bit). I have deleted all stored passwords using Settings -> Privacy and Security -> Show Passwords. As expected, when I try to retrieve emails a pop-up appears asking for the password - which I save. However, when I try to send an email there is no pop-up and the remote server rejects the email. How do I set a new outgoing password?

i get a pop up when a new email come in on my main monitor. i have many. sometimes i would like to just delete it there rather than open up the inbox to delete once it arrives in my in box. a delete trash can icon would be nice to have on that pop up

I would like to delete a mail without opening the mail or without a right-click.

Please refer the images to understand what I am saying.

The attached pic is from Windows default Mail app. I was talking about the red delete icon. Is it available in thunderbird too?

Thank you.

Short background: Critically low on disc space. Windows pointed out a potentially extraneous 8.5gb NS3TMP Thunderbird file. Extensive Googling convinced me it would be safe to delete this file. To be safe (HA!) I first copied it to an external drive just in case things went south. They did.

After the copy, I went back and deleted the NS3TMP file. However, much to my horror, instead of deleting 8.5gb as expected, 30.5gb got deleted. After that, Thunderbird would not start claiming my profile was missing.

I copied the 8.5gb backup file back to its original place. No joy. Same message from Thunderbird.

At this point, I recreated my profile pointing Thunderbird to my Outlook email account.

I could now sign into Thunderbird and T'bird started populating the inbox and sent folders, but only partially. Worse (MUCH worse) my critical Thunderbird local folders were nowhere to be found. I attempted several folder recovery procedures to no avail.

I confess, I do not know how Thunderbird works its magic behind the scenes. Were my local folders part of the surprise 30gb file deletion and thus gone for good? Would the original emails that had been dragged into the various folders still be sitting on Outlook's servers?

As I said, totally self-inflicted but hopeful there's a road to recovery.

Any assistance or consoling words would be much appreciated.

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?

I keep getting the attached error msg when trying to send an email. I've changed it to "Normal Password" as advised, but it's still the same. Any help would be appreciated. Regards norman

Hi!

I realised that Thunderbird keeps deleting my messages in every account from the trash folder. I didn't change any of the settings and I checked them again - as you can see in the screenshot, the settings say to not delete messages in the trash. It's a catastrophe, because I've lost messages that I had to check again.

-> Is there any way to restore messages that Thunderbird deleted without my permission? -> Is there any way to make sure that Thunderbird does not delete messages any more?

Thank you!
