Guten Tag, seit dem Wechsel vom Hosting wird bei den Mails der Übermittlungsstatus (DSN) anfordern nicht mehr angezeigt. Woran liegt dies? Danke fürs Feedback. Grüsse TS

For months I was experiencing the problem of "Thunderbird not responding" occasionally. It was a short duration issue (a few seconds to a minute). I reinstalled Thunderbird several times without success. I read almost every comment available online about this problem and I tried many ideas and recommendations I found without success. Most recently the problem became so serious that it was not a nuisance any longer. It was nearly impossble to work waiting for minutes to open an email or to continue typing while preparing a message and being interrupted by the problem I am describing. I ran Thunderbird in safe mode and determined that none of the add-ons is causing the problem. I turned the firewall OFF and determined that firewall was not causing the problem. I then decided to run Thunderbird in Offline mode and found that the program works normally. Then while in Offline mode I decided to download more messages and the program asked me if I wanted to switch to the Online mode. I said yes. New emails were downloaded and without going back to the Offline mode I was able to work normally without any occurrence of the "Thunderbird not responding" problem. I have been using this workaround for several days now. I download a number of eamails. I try working in Online mode and I cannot do it. I switch to Offline and work fine. I switch back to Online mode and I don't see the problem any longer for the whole day. Do you have any idea as to the origin of my proble? I am running Thunderbird 115.10.2 64 bit on Windows 11. I had the problem originally using Lenovo T490s and more recenlt Lenovo X1 Yoga

There are many answers to the question of how to disable message threading. All are from earlier versions than mine, which is 115.7.0 -- as witnessed: Sorry! 0 results found for ‘disable threading in version 115.7.0’ for ‘Thunderbird'

Thunderbird seems to have so many minor changes and alterations in the recent past, that basic usability is affected. Not a good thing.

Once before, a few years ago, Thunderbird got so out of control that I had to go to a different mail client. Are we back to that?

Can I upgrade my Thunderbird 115.3.1 from 32 bit to 64 bit?

My Thunderbird has recently automatically updated to V115.3.1 but remains 32 bit. When I go to the Thunderbird download page there doesn't appear to be a choice of version.

I opened Thunderbird this morning and there were no issues. Closed it and just now reopened and I'm getting this message: Thunderbird detected a potential security threat and did not continue to live.thunderbird.net. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

It downloaded 28 emails but will not let me see/access them.

Can anyone help? Thanks, Linda

My friend has been using Thunderbird for a long time. Recently I installed her new PC and restored her account profile using the profile folder on her old PC. So far so good. The problem is that her mails are not organized in folders on the mail server but she has a whole collection of folders in her Thunderbird mail client and is concerned about loosing her mails if the new PC (or the disk) would crash at some point. Of course she could just re-install Thunderbird after fixing the crash problem and sync with the mail server, but then the folder structure would be lost. First I considered using a back-up program to keep a back-up of her Thunderbird profile using cloud storage. My second thought (should have been my first thought...) is that she already has a back-up, namely the mail server. The ISP does a better job than any local back-up program to keep her mails safe. Only the missing folder structure remains a concern. So here is the question: if I change the setting to sync all folders with the mail server, what will happen: 1 - the folders in Thunderbird will disappear (only the folders, not the mails) because there are no folders on the mail server 2 - the folder structure from Thunderbird will be mirrorred on the ISP's mail server. Which one is it?

I get a message like this every time I start Thunderbird. The topic came up last year but the conclusion was along the lines of "...this problem will be fixed in version 128" but it was never clear whether or not the User followed Mozilla's support replies or what they had to do to clear the email message from Thunderbird. .....Well I'm running version 128.1.1esr and the problem still exists.

My questions:

1. What is Thunderbird trying to do? Compact individual email files? Compae from ct the whole Thunderbird Profiles folder?

2. Is the problem the size of the Profiles folder or the overall size of the hard drive the Profiles folder resides on? What is the Hard/solidstate drive is the maximum?

3. Is the problem related to the amount of Free Space left on the Hard/solidstate drive or is the issue the number of individual files?

4. Is the issue related to the number of Thunderbird files and/or folders OR is it related to the total number of files and/or folders on the hard drive?

5. Is there a limit to the number of sub-folder levels that Thunderbird can navigate?

Thank you.

Tom

My thunderbird works okay, but when I select emails from imbox folder to delete it takes too long. I researched to find the problem and the only option I found was to add an exclusion to the profile folder on my windows security antivirus. Now I can select emails from the imbox and delete them without a problem, but my concern is if I will be vulnerable to virus.

Outlook says that it will no longer let third party mail apps like Thunderbird to access Outlook email as of September 16, 2024? What do you recommend?

"Action Needed – You may lose access to some of your third-party mail and calendar apps

Update your sign-in technology before September 16th, 2024 to maintain email access.

The safety and security of your information is top priority for Microsoft. To help keep your account secure, Microsoft will no longer support the use of third-party email and calendar apps which ask you to sign in with only your Microsoft Account username and password. To keep you safe you will need to use a mail or calendar app which supports Microsoft’s modern authentication methods. If you do not act, your third-party email apps will no longer be able to access your Outlook.com, Hotmail or Live.com email address on September 16th.

What do you need to do?

If you are receiving this email, you are currently using an email or calendar app that uses a less secure authentication method to connect to your Outlook.com email account. You will need to upgrade your third-party mail and calendar app to a version which supports modern authentication methods.

Microsoft provides free versions of Outlook for your PC, Mac, iOS, and Android devices which can be easily downloaded and connect to your email account. Using an updated version of an Outlook application will ensure you are connecting in the most secure way.

How can you set up your Gmail, Apple Mail, or other third-party mail application?

Various non-Microsoft applications will have their own steps for connecting to your Outlook.com email account using modern authentication methods. See our help article - Modern Authentication Methods now needed to continue syncing Outlook Email in non-Microsoft email apps. However, you may need to contact the creators of those applications to provide you with instructions. In many cases, simply removing and re-adding your account with the latest version of that application will configure it to use modern authentication methods.

I have made many attempts to move Thunderbird from my old Windows machine to my new one. The old machine was running Windows 8.1, the new one is Windows 11. I've exported, then imported using all the different ways listed but can't get all the data. I've had some success doing it one account at a time including my address book and accounts setup information and they are working properly but can't get the folder data for my accounts or any Local Folders for some reason. I don't want to mess up what I've been able to successfully migrate so I'm reluctant to doing a mass migration again. Is there a way I can migrate doing it one folder at a time without messing up the other ones?

In the past, I had followed this post and created the userChrome.css file so that when I have my emails shown in Table View, if one email within a thread is unread, the whole thread is collapsed, but the subject line remains in bold.

With this latest Thunderbird update to version 115.13.1 I have lost the functionality; now the subject line of the collapsed thread shows as underlined. How can I go back to my preferred bold view?

Thanks

Yesterday I tried the 115 (Supernova) and I was disappointed because of the toolbar on top of the TB window: I think that you should let the user choose where put any toolbar, and I didn't find the way to move in its "classical" place (not at top but below the menu). There is a way to do it? And if not, please consider to give it as soon as possible.

I'm on tb 128 and use roadrunner. I see my emails on spectrum server but can't download them? I was using pop, they said imap is needed.

   Username: Your full Spectrum email address

   Password: Your Spectrum email password

   SSL: On

   Protocol: IMAP

   Incoming Server Port: 993

   Outgoing Server Port: 587

   Requires Authentication: Yes, or checked

Thunderbird’s connection to one of my gmail accounts failed today.

I removed the account and then tried to add it again to Thunderbird.

When logging in using a Google generated App password, I receive the following 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."

OAuth2 is in place, and I’ve carried out all other recommended checks I can find on your website. My other Gmail accounts are working fine.

Please can you help? Many thanks.

I currently have Thunderbird set up using POP but would like to change to IMAP to sync with my other devices. If I change from POP to IMAP, a. will that affect the emails that are currently showing in Thunderbird and b. will the emails that are in Thunderbird then appear with my other points of access?

For years I have used the extension 'Calendar Tweaks' because it colorizes the entire event in the calendar. This extension is no longer compatible with versions of Thunderbird after 74 so I have stop updation after Version 69. However in resolving problems with authorization I needed to update to the current Version of Thunderbird so my events in the calendar now just show the category color at the edge of the box instead of the entire box. Is there a way in Thunderbird to colorize the entire event box or another extension that does this.
