Thunderbird and Windows 11 both updated yesterday or today. In several archive folders, messages since about a year ago are now missing. Is there a way to restore to the folder contents as of about 24-48 hours ago? Inbox, Deleted, etc do not seem to be affected.

On Friday 24/09/06, I deleted my thunderbird-profile-file without immediately realizing it. I realized it on Monday 24/09/07, by opening the program and getting an error message. A new profile-file was immediately initialized by the program and also a program-update was made to version 128.2.0esr (32-Bit)). Unfortunately, I do not know the version, I used before the update Using your instructions from the Mozilla knowledge-base, I was able to restore the file-situation, as it was before my mistake killing my profile. Although trying now for three days getting the old data (inbox, sent mails, address book) in the new profile by importing or over writing I didn't have any success. Trying to import old profile-data by the program-tool results in an error message. When overwriting the existing files with the old ones, I get new folders, but they were all empty. After long time of research in your knowledge-base, trying mentioned solutions without success, I suppose that it is no more a question of recreating a knew profile but a question of the program-update made on Monday and a data conflict between the two program versions. I Think the new version cannot handle with the old data. I would like to install the version I used before the update, but do not know whether which version it was nor where I could find an old program-version? Or is there a possibility to manage old data with the new version, and I do not know it? Perhaps you can reconstruct the old program-version by seeing the content in the folders of my old profile-file appended below (explorer screen shot) I would be grateful if You could help me retrieving my old data (Inbox, sent etc.).

Your instructions for changing outgoing server settings for Microsoft SMTP server require changing authentication method to OAuth2. Unfortunately this doesn't appear in the drop down menu. I only have No authentication, Norman password, encrypted password, Kerberos/GSSAPI, NTLM. Which of these should I chose instead or how can I get the correct setting to show? Security settings for incoming server settings are fine (ie. OAuth2 can be selected).

Since yesterday, I suddenly cannot receive mail from the office365 server with thunderbird. Authentication passes, but timeout occurs when receiving mail. There is no problem with sending mails. I did not change anything in thunderbird settings yesterday.

[setting] Server Type: POP Server name: outlook.office365.com Port: 995 Connection Protection: SSL/TLS Authentication method: OAuth2

I tried changing the authentication method to OAUTH2 for my Outlook live mail account (POP). For that, I had to change the server name to office365.com. After restarting Thunderbird, I was able to download new messages but all the old messages already stored in Thunderbird disappeared, even though Thunderbird still shows the same old Local Directory as being used.

How do I change the authentication to OAUTH2 & get my old messages back?

If I delete & again create the Outlook live account, would it effect my old mails/filters ?

Hi there,

So, I have a professional account with outlook.office365.com for my professional email (which is aleclercq@sobemab.fr). But I use my personal email to contact you right now. We have Black in Mail operating for all new email and then I can't get email from you unless you authenticate yourself.

Anyway, my configuration is : HP computer, windows 11 Professional (build 22631.4112) Thunderbird version 128.2.0esr (64-bit). Add-on Owl for exchange.

Now, when I launch Thunderbird, it connect properly and I do receive emails. All good.

But the problem comes when I want to SEND an email. It doesn' t work. I have attached some screenshots for you to see. It will be easier that way, I guess. I'll appreciate your help on that matter ASAP. Outlook is ok, but I can't stand it and I really want to use Thunderbird. :)

Thank you Best Regards Alexandre

I have used MailStore Home to archive then export an Outlook PST file into Thunderbird. The Export appears to have worked, but I notice that the resulting file structure in Thunderbird Local Folders has "MailStore Export / Outlook Outlook Data File / Inbox", with all my folders residing under the inbox folder (which they should). Is there a way I can change the Local Folder structure to remove the top level "MailStore Export / Outlook Outlook Data File" and leave the top level as "Inbox"? See image.

How can I restore Thunderbird settings and/or emails that were lost in the upgrade to version 128.2 (for Ubuntu)? Files for the previous version are still in the hidden .thunderbird folder on my hard disc, but the new version won't recognise them (even if I move them into the snap/thunderbird folder. I have an email backup, but version 128.2 doesn't seem to have a way to restore backed-up emails.

Please advise how I can get get the correct IMAP server address. I need it for Google Data Migration .

I am migrating .mbox file to my new google workspace

I have tried entering server name under server settings(imap.gmail.com) but unfortunately that does not seem to work.

In the Thunderbird calendar, I'm trying to create a repeating event that occurs on the fourth Wednesday from Sep 25, 2024 through Jan 22, 2025.

But each time I try to set it up, using Jan 22 as the end date, Thunderbird changes the end date to Jan 21 and so the last event does not get created. I've tried several times and this keeps happening.

What's going on?

Hello,

I am still having problems with Thunderbird crashing on startup

I first asked about this issue on the 2nd September, here: https://support.mozilla.org/en-US/questions/1461731

I have been submitting Crash reports per business day except for the last couple.

Here are the Submitted Crash ID's, I have been submitting reports as the crashes happen. :

Crash ID: ⁨bp-3b69ccf2-e3c1-431c-bada-e4f2e0240902⁩ Crash ID: ⁨bp-4c4852b8-6599-40b5-97b1-943930240902⁩ Crash ID: ⁨bp-09a86b67-a698-4c2e-a98f-e89f70240903⁩ Crash ID: ⁨bp-526167eb-c915-47fc-8065-f0b140240902⁩ Crash ID: ⁨bp-8965165b-c579-415d-9cb3-cdd010240903⁩ Crash ID: ⁨bp-a8aaf596-7dfc-43b5-8526-e204d0240902⁩ Crash ID: ⁨bp-b45149f4-8bb8-44df-84e4-b78fe0240902⁩ Crash ID: ⁨bp-c284df19-7d63-469a-af6c-9ff6c0240903⁩

More available if needed

Notably, I have 2 computers each with Thunderbird, each accessing the same account. I have no problem on the other computer. I am using no addons on the crashing computer. I have uninstalled and reinstalled the latest version, computer restarts - still crashing. I have checked my RAM. 16GB on board - Basic Graphics Processing - Intel Iris XE.

Any assistance would be appreciated.

Best

9-4-2024--For months the filters for my messages have not ALL worked right. Some of the older ones may work. The new filters disappear. I'm thinking it is because the Create Filter page does not display all the way to the bottom of the page so I can see and click ok to save it. Please fix this so the Create Filter page will RESIZE so I can save the filters I create. Mozilla Thunderbird programmers--Can't you write a program better than this?? Why can't you fix a problem that has been there for months maybe a year? Whatever is causing the problem please fix it.

My Thunderbird just upgraded to v128.2esr Nebula

I was using Cards view and it was nice, but it seems the Cards just got wider vertically. They used to be 2 lines of height, and now they are 3 lines.

As I understand, the 3rd lines is only used to display "X replies", but I use the "Unthreaded" sort option, so the 3rd line is always empty for me, and takes more space for nothing.

As you know, vertical screen estate is limited with our 16:9 screen, so please give us an option to reduce the cards view vertical size (or have it automatically remove that 3rd line in Unthreaded view)

thanks

My email provider Frontier was taken over by YAHOO. Yahoo wants to delete make changes and reload to Thunderbird. Can I do this without loosing all my email history and data accumulated it that email group. I have 2 email groups affected by this change. Thank you for your help. Del

HI! For the message "newer version of Thunderbird may have made changes to your profile", I was able to click on new profile & got all my email back (I think) but my folders under Local Folders are gone. Can I get them back?

The very informative page for this topic says that "You will not lose any personal data or customizations. Any previous profile data is saved and associated with the first Thunderbird installation that was opened after this change." Does that include Local Folders set up on the old version?

Thanks

Using TB 115.15. When I move a large number of messages (200 or so) to a sub folder the move goes fast until it gets toward the end, then it locks up until it finishes a few minutes later. When I tried to move over one thousand messages at one time, I let it run overnight, some messages moved, some only moved a date header of some earlier time (all the same time) and all messages were left intact in the original directory. After moving the messages a few at a time, I had to manually delete the duplicate messages in the sub folder. What is the maximum number of messages Thunderbird will move at one time.

I just updated to V128 (from 78) and I had a bunch of custom named in added to mu dictionary.

I still have the old version on mu computer, how can I either export from the old version and import to the new version, or, can I simply copy over my custom dictionary to my new profile somehow?

Thanks, Mark.

I can't seem to update my Thunderbird mailing lists. I know how to do it, and I go through all the steps to add an address, click "OK" but the mailing list remains unchanged. And when I try to create a whole new mailing list, it lets me do it--that is, create the mailing list--but there are no addresses in it. I attach a couple of screen shots:

First, before I hit OK. Second, after I hit OK.

This has been going on for at least a few months. I thought an update would help but it didn't. Please advise how to fix this problem.

Thank you.
