happens on Windows 11 also

Every birthday or holiday reminder (I haven't entered these) generates an error when i select snooze or snooze all. The reminders I have entered snooze fine. Using gmail calendar.

On Saturday morning 27 June 2026 I tried to login my Orcon email account via Thunderbird (which I have been using for a long time). But my login didn't work, I got a message saying "login to POP3.orcon.net.nz with username habitation failed." On 30th June 2026 I reported the problem to Orcon.

Orcon gave me the following settings for Thunderbird. I have done that and even made a new account: Incoming Server Type: IMAP Mail Server: imap.orcon.net.nz Port: 143 SSL: Off Authentication: On (username and password required)

Outgoing SMTP Server: Mail Server: smtp.orcon.net.nz Port: 25 SSL: Off Authentication: Off

Since then I have spent many hours and going around in circles with Orcon's Technical Support to resolve this, but no luck. They blame Thunderbird. I used Thunderbird Troubleshoot Mode. The message that comes up reads: login to server mail orcon.net.nz with username habitation failed. Please can you check that your server settings above are correct? And if there is a bug? Irma

I have been using Thunderbird for 20+ years, maybe as many as 30. Forever. I have moved my profile across several versions of Windows and multiple computers. There are files in the root of the profile with a modified date of 2009. There may be older ones in sub-directories. There are 18 folders and 125 files. I suspect a lot of this is clutter left over from earlier versions of Thunderbird. In the Mail folder alone there are several hundred files and folders excluding the WDSEML files and actual emails.

I'm toying with the idea of starting fresh with a clean install of Thunderbird and getting on the correct release channel but I don't want to bring along what appear to be hundreds or thousands of unused files and folders.

I there anyone that can identify what profile files and folders to keep and what can be deleted?

Thanks for your consideration.

I ran TB in troubleshooting mode and the problem was still there. I deleted the account and created it again but it did not help. I killed TB and restarted, no joy. I rebooted Windows (build 26200.8875), no help. I have a working hotmail account so I compared the Account Settings and Server Settings, they are identical. Both accounts can contact the Mail Server and I get the Certificate ok. I could add the hotmail email account to my Mail app on iPhone and iPad and that worked fine, so seems like a Windows Thunderbird issue. I tried changing the password of the account to the real password but then restarting TB I got an error message: "login.microsoftonline.com needs you to confirm access again to keep syncing with your account. Username: <foo>@hotmail.com". I do not know how to handle that.

In recent update several duplicate folders were installed in three different email accounts. Point to them there was a 'delete' button enabling elimination of duplicates. However, on two accounts, 'Drafts' duplicates didn't have the delete button enabling elimination. How to clean up?

Does resetting your primary password in Thunderbird only delete the usernames and passwords in Thunderbird or does it also delete the usernames and passwords in Firefox?

Thunderbird: 153.0 (64-bit), Windows 11

Have noticed that my TRASH Folder is missing in the folder view. The actual folder exists, it just will not display.

Also creating new folder under are created (I checked the mail folder) but will also fail to display. Creating subfolders into an existing folder works. And moving it under INBOX, making it a subfolder also works and displays

Any ideas how to recover/display the TRASH folder and new folders ? As the TRASH folder is missing it means I have no way to look at deleted email or recover them. Nor any way to search delete emails.

Emptying the TRASH works - no errors.

TB suddenly moves messages from inbox to trash automatically without any interaction. Search through the forrum shows that it has been asked for already, see [https://support.mozilla.org/en-US/que.../1588804|1588804], similar postings can also be found with you search engine.

As described in other postings, the messages are moved from Inbox to trash. When moving them back manually from trash to inbox, they are moved to trash again immediately.

• it happens for the default account only,
• there're no filters at all in TB,
• junk detection is disabled,
• Settings->General Storage is all disabled,
• (account)->Settings->Server Settings has checked "move deleted messages to trash",
• (account)->Settings->Storage is all disabled,
• Inbox->Properties "Repair folder" does not help,
• Inbox->Properties "rules is set to "use account settings" (and greyd out "do not delete messages"),
• exactly same behaviour when starting TB in save mode,
• manually deleting all *.msf files (for inbox) does not help,
• manually deleting xulstore.json does not help,

Additional notes, which are not related to the problem, IMHO:

• IMAP on port 993,
• no other clients anywhere are connected to that account,
• TB configured for more than 10 accounts, more than 500 folders and sub-folders,
• host with > 16GB RAM, TB uses 3GB virt,
• problem observerd in older TB also, at least 13x.x

I'd be happy to debug/trace the problem if someone can give me detailled insructions how to start TB with debugging. Please feel free to ask for about:config settings as they are non-ambiguous and language independent ;-)

Thanks.

clicking on 'get messages' produces no response. zero. Nothing happens. two email accounts are affected.

Consistently Reproducible.

The Windows 10 PC crashed after an update, but I have command line access. I copied the profile folder from the Thunderbird installation to a USB drive, but can't find a way to move the subfolders (like 'name' and 'name.msf') to an existing installation on the new PC.

Is there a way to import these into the new installation?

I haven't used Thunderbird on an office computer in several months. When I opened it, the most recent emails were from October of last year. Nothing seems to be updating or refreshing. How can I reactivate the account?

On my PC - Initial problem was T-bird took forever to load and virtually all new msgs went to TRASH and I had to move to IN-Box. Per help from David - Saved off profile, and reinstalled thunderbird from thunderbird.net. No change. Then UNINSTALLED T-Bird (profile still intact). Now just attempts to open "Looking up imap.comcast.net", but won't open/connect and to close the app I must use WIN Task Master. Can't get to any msgs, etc. Also, in the past when I was able to open, the banner or bar at the top of the page had hundreds of email icons. I sometime have over 1000 emails in my in-box!! I have years worth of emails in folders on T-Bird which I don't want to loose. Help. Thank you. I have a "working" version (with the "trash" and slow loading issue per above) on my laptop, so I can access suggestions on that version of T-Bird. You could also send any suggestions to x@gmail.com

No matter what I try, reinstalling thunderbird, enabling IMAP and cookies, ensuring server settings are correct - oauth2 etc, using Mozilla Firefox AI help for most of one day until all avenues were exhausted, a Microsoft support worker taking over my computer and reinstalling Thunderbird then saying the fault lies with thunderbird..... I cannot connect to the Microsoft smtp server. message says connection failed and on retry or new password options message says check outgoing sever settings and authentication

I have followed your instructions at https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer and gotten nowhere all day. on it. You have "Profile Folders", a folder called "Profiles", a bunch of profiles (folders) inside the Profiles folder and profiles in Roaming and in Local paths. When I get the old profile 'k41******' copied to the new computer in both the Roaming folder and the Local folder the Thunderbird program still will not show me the old files. I don't need any of the thousands of emails in the old computer, just the Templates in one account. This should be easy. I should just copy the profile k41***** ect. and paste it into the "Profiles" (notice the pleural there) and then Thunderbird should work. But it does not.
