Thunderbird-Hilfeforum

Now and then, when I press the Enter key, Thunderbird moves the current email message from Inbox to Trash instead of opening the message in a new tab.

I am using Version 115.11.1 (32-bit) on Windows 11.

The folder "popstate-1.dat" appeared under my email account below Inbox, Drafts, Sent, Archives, Junk and Trash. I have attached an image showing the folder located below Trash and above Local Folders.

Can it be deleted? Is it serving a purpose?

I recently deleted old messages from the various Local Folders folders.

Thank you.

I inadvertantly copied a chunk of received Inbox messages from my MS Office365 Outlook account into the trash. Unfortunately, they didn't show up in deleted items nor in trash. I went into Outlook on the WebApp and discovered that all of the inadvertantly deleted emails were found under recover deleted emails. So within Outlook I recovered all mails. So far, so good.

Now I have all the mails listed in the Inbox on Outlook. But when I open Thunderbird again, the recovered mails do not show up. It seems that Thunderbird does not fully synchronize the folder and the recovered emails are not downloaded. Instead, all mails are once again removed from the Outlook Inbox. The previously recovered mails disappear again from the inbox of OWA and I have to recover them all again.

I have already tried several things. I created a new folder and moved the recovered mails to that folder. All in the hope that this folder will then sync properly. Unfortunately no. The folder does not sync and as soon as Thunderbird is closed again, all mails are also deleted again from the new folder on OWA.

I even reset Thunderbird and linked Thunderbird to the account again. Unfortunately, the same thing happens again. The recovered mails are not displayed in Thunderbird and after closing the program, the mails are deleted again in OWA and I have to recover them again.

Any suggestions?

Best regards

Hi, I have just created a new folder within Local Folders, and want to move emails into it. When I click "move to" the new folder is not there. All the old folders are there - 10 of them. Is this a limit? Can it be enlarged?

With the moving of Cox emails to Yahoo would it be feasible for Thunderbird to put an instruction list(with screenshots) of how to get all our TB email accounts from Cox to TB? Do we have to delete all our TB email accounts and re-enter them into TB under the new Yahoo or can we just change the server settings on the existing Cox settings? If just changing server settings what are the settings for the new yahoo? All my accounts are IMAP so if instructions could be made, maybe one for IMAP and one for POP for those who use either. Thank you

My service provider is QX.net which uses Magic Mail web email. I have Firefox 115.ll, 64 bit. I have Thunderbird 115.11.1, 32 bit.

The Magic Mail on my Server shows 253 unread messages. I have identified some of those 253 messages in my Thunderbird folder and they have been read, and are shown as read in Thunderbird. There seem to be 3 different dates involved. This is a concern as it is unacceptable not to receive all of my messages.

Please advise what I can do to address this so that I receive all my messages and so that when I have read them they are shown as "read" in Thunderbird and in Magic Mail.

Thank you so very much for any help.

I'm a keyboard only / screen reader user. I have been using thunderbird for a week and love it. I use the portable version. Anyway, is there a way to rearrange my email accounts without dragging? when I add an account I want it to not appear at the bottom of the list. could there be a way to rearrange said accounts either with a keyboard, or via a setting to move up and down the account via buttons and have it take effect in the tree view? I've been looking for such a solution for a while now. If not, might there be an add on I can use which can aid in doing this? thanks.

This just started. 115.11.1 (64-bit)

I cannot select multiple messages in any folder and move them to any other folder/ Filters will not work either.

As an example, I select 3 messages if my inbox and try to drag them to trash

I get an error popup that says "The messages could not be moved or copied to folder 'Trash on Local Folders' because writing to folder failed. To gain disk space, from the File menu, first choose Empty Trash, and then choose Compact Folders, and then try again."

Trash folder had been compacted and emptied.

Thanks for any help.

Company uses office 365, I have my Thunderbird. Since a couple of weeks sync issues appear (i.e.: TB has no right to delete folders in office 365). Finding a solution took several hours in various forums - nothing helps. - the only suggestion I didn'T try so far is asking the office365 helpdesk.

Problem description: When I delete folders they reappear at the old position. empting the trash yields also reappearance in trash. Same for moving folders - a copy is made, but at the old position and empty folder remains. They are gray - so hidden folders. Overwriting obviously does not work, as the folder already exist, but is not accessible. subscribing/unsubscribing does not work. In office365 the folders do not occur. If I create a folder in office 365 (web, outlook) it appears in TB. When I delete it in office 365 (web, outlook) it disappears in office 365 (web, outlook) but reamains - in gray - in TB. By now, the number of gray empty undeleteable folders has grown significantly. Only solution I got sofar is to switch from TB to outlook. :/

I'm a freelance writer, and often when querying an agent or publisher, they ask me to send the first "x" pages of in the body of the email (NOT as an attachment), and they want it double-spaced. It's double-spaced in Word, but when I paste it into T'bird, it's single-spaced. I've tried everything I can think of, to no avail. Is there a solution or work-around?

Recently the email display has been changed and not by me. At present I cannot receive emails as previously. Also I wish to revert to the previous display of my emails if possible. I can access email via the email.telstra,com site but I wish to stay with Thunderbird. I also do not get emails to my mobile as before

One of my email accounts (the main one) has stopped downloading to my asus Vivobook 15 laptop. My other two accounts are downloading okay and the account that is not downloading to my laptop is downloading to my Samsung mobile phone okay. Please can you help.

I have a SOGo server that holds my address book. The SOGo web interface allows setting of custom properties, something I have used for a long time without problems. I have accessed the address book with Thunderbird both on Windows and Linux (today Windows 11 and Debian 12).

Lately I have problems with synchronization and now I have tried to understand why. I believe that the problem is connected with the transition to vCard Storage in Thunderbird. (See https://developer.thunderbird.net/thunderbird-development/codebase-overview/address-book)

In the Thunderbird error console (on Debian 12 using Thunderbird 115.11.0(64-bit)) I get for a simple VCARD with one custom property (which I created in SOGo):

09:24:18,136 carddav.sync: Error parsing: BEGIN:VCARD UID:56377-6667FA00-1F-59090880.vcf VERSION:3.0 CLASS:PUBLIC PROFILE:VCARD N:With Custom 1;AAAAAAA FN:AAAAAAA CUSTOM1:My custom value END:VCARD CardDAVDirectory.jsm:595:15

09:24:18,136 NS_ERROR_UNEXPECTED: Unable to set Custom1 as a property, use vCardProperties

   setProperty resource:///modules/AddrBookCard.jsm:394
   vCardToAbCard chrome://sogo-connector/content/messenger/startup-overlay.js:551
   fetchAllFromServer resource:///modules/CardDAVDirectory.jsm:590

CardDAVDirectory.jsm:596:19

It does not matter if the SOGo Connector plugin is activated or not.

Hi,

I'm trying to automate / batch set the "When getting messages for this account, always check this folder"-setting for a large number of folders so I'm trying to figure how Thunderbird stores the setting(s) of which folders to always check for new mail.

Checking the `global-messages-db.sqlite` it seems like all folders that have the "always check folder"-setting have a `indexingPriority` value of 30 in the `folderLocations` table, but simply setting it to 30 for other folders does not enable the "always check folder"-setting so I guess that is set elsewhere. Where?

Also what other settings are set for the folder when enabling "When getting messages for this account, always check this folder" ?

Thanks in advance /frax

Dear Support,

we want to intergrade Thunderbird to our Microsoft 365 (Exchange Online), but we have massive problems with the authentication of our users.

I have allready configured an the Enterprise Application for Thunderbird in Entra ID and the Clients, excactly as documented in you article: https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202

We have conditional access policies in out Entra ID, which allow only comliant devices to acess out Exchange Online.

The Thunderbird clients are running on these compliant devices (Windows ans macOS), but it seems that the client is not passing this information through the Oauth authentication (see screenshots 01 to 04 - I uploaded the configuration and all the steps of authentication).

I searched the internet for more then 3 days, but the only thing that I have found about this problem is this: https://bugzilla.mozilla.org/show_bug.cgi?id=1697805

In our Entra ID, we see in the sign-in logs, what excactly is happening with the conditional access (screenshots 05 to 07)

We use the newest client versions of thunderbird.

Can you please help me on this? We realy want to continue to use Thunderbird!

Kind Regards Ioannis Kyriakidis
