Thunderbird-Hilfeforum

Hello,

since Saturday, 9th Sept. 2023, ca. 14:00 GMT my Thunderbirds are producing error messages.

I have added four different outlook.com email-accounts, each with IMAP+TLS+OAuth2 as incoming server and SMTP+STARTTLS+OAuth2 as outgoing server configuration. The error messages are only regarding these outlook.com-accounts. A gmail.com-account with the same settings is not affected.

I encounter constantly popups with the following error messages: - "...user ist authenticated but not connected" - "the server is offline" - something like "authentification error while connecting to server outlook.office365.com"

Also the Page where i should enter the password to create the OAuth-Token keeps opening and closing before it could load completely.

The most astounding thing is, the synchroniziation seems to work nonetheless. It's just the messages that annoy me.

Here is an entry from the Thunderbird error-log: "mailnews.oauth: Error response from the authorization server: invalid_grant; AADSTS50196: The server terminated an operation because it encountered a client request loop. Please contact your app vendor. (...) https://login.microsoftonline.com/error?code=50196"

The problem occured more or less suddenly on 3 different PCs: - Two Windows 10 Pro 22H2 machines with the Thunderbird versions 115.2.0 and 115.2.1 - A Fedora Linux machine where Thunderbird 115.2.0 is installed via Flatpak

What I already tried with no success: - De- and reinstalling Thunderbird with deleting _all_ user Data - Upgrading Thunderbird from 115.2.0 to 115.2.1 - Revoking the access for the Thunderbird-app in the Microsoft.com account OAuth-Settings and granting it again when creating a new token by logging in with Thunderbird

What my inquiry has delivered yet: - Thunderbird seems to have problems to remember the OAuth-Tokens. When I look in the privacy settings at the saved passwords I can see that the passwort seems to change constantly. In contrast, the Google-gmail.com-account keeps the same passwort. - It seems to be especially triggered by closing thunderbird and opening it again shortly afterwards, though it does happen without doing so too. - The error messages pop up and the password-page opens mostly when I click on a folder (presumably because Thunderbird is trying to sync it then)

My accounts seem to be fine. I have no problems accessing them with OAuth2 via K-9 Mail on my Android 13 phone. I can also log in via the Web Interface.

Thank You for your Time!

After update thunderbird sending errors in all accounts. Removng all data (profile and cache folders) and reconfigure not help. Use:

• Xubuntu 22.04
• snap install
• version 102.9.0 (64-bit)

Error concole: Exception { name: "NS_ERROR_FAILURE", message: "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIFile.createUnique]", result: 2147500037, filename: "resource:///modules/MimeMessage.jsm", lineNumber: 72, columnNumber: 0, data: null, stack: "createMessageFile@resource:///modules/MimeMessage.jsm:72:10\ncreateAndSendMessage@resource:///modules/MessageSend.jsm:128:41\nCompleteGenericSendMessage@chrome://messenger/content/messengercompose/MsgComposeCommands.js:5987:23\nGenericSendMessage@chrome://messenger/content/messengercompose/MsgComposeCommands.js:5903:11\n", location: XPCWrappedNative_NoHelper }

I just noticed that if I check the SENT folder, some of the emails I sent have this text in the body part.

"This is a multi-part message in MIME format.

Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: 8bit

[HERE THE CONTENT OF THE EMAIL I SENT]"

I'm wondering if they are sent like that, what the receiver will see and if there is a way to prevent it.

The email account is using IMAP and as far as I know it happen just to that specific email account. The emails are sent using Thunderbird. I'm using the latest version of Windows on a laptop. I'm using the following Thunderbird extensions (latest versions): - Compact Headers - Send Later - Mailmindr - Quicktext

Hello, I'm new to Thunderbird. This is the first time using.

I'm trying to Archive emails, to clear up space on a near full email server. I've set Account Settings/Copies and Folders according to various posts on this forum. The first few Inbox test emails worked, using the Archive button, and archiving emails from the Sent folder seems to be working ok. But now whenever I try to archive emails from the Inbox, I get this error:

The current operation on 'Inbox' did not succeed. The mail server for account xxxxx@serviceprovider.ca responded: UID COPY failed.

I haven't been able to archive any more Inbox emails. I've also tried just drag/drop, but I'm getting the same error and the emails return back to the Inbox. I'm only selecting 20 emails at a time.

I reinstalled Thunderbird overtop. But no change.

I've tried Compacting, and Repair Folder. But no change.

My system is Windows 10. I originally installed version 68 and the auto updates has upgraded it to the current version. Message Archives is set to Yearly archived folders and I've checked "Keep existing folder structure of archived messages". My Archive folder is structured: "2021" with subfolders "In" and "Sent".

Not sure what to try next. Should I revert to a previous version?

Any assistance is appreciated! Thank you.

I have been using Thunderbird as my email client for many years with Spectrum. I recently hit a problem with sending mail and Spectrum support has not been helpful ("We don't support 3rd party clients").

I can no longer send outgoing email using Thunderbird on any of my Spectrum email accounts.

I have no problem receiving incoming email on any of these accounts. I also don't have a problem sending email from my iPhone or iPad.

Any assistance would be very much appreciated.

Hi, I've been having trouble with Thunderbird for a few days now.

I recently turned on and updated my laptop, which shares the same thunderbird accounts as my desktop. I had to update Thunderbird and log back into my google accounts because it had been some time since I last used that device. I noticed that I wasn't receiving emails on my desktop anymore. I did some research and tried applying fixes that I read online.

So far I've tried: Deleting my saved passwords > didn't work Removing the account entirely and re-adding it > Thunderbird failed to find the settings for your email account. Uninstalling Thunderbird and deleting any saved profile data > Same as above.

I did install a new router, a Netgear Nighthawk but I'm not sure if this is the cause of my trouble as both my mother's PC and my Laptop use Thunderbird. Both continue to work.

I use Kaspersky for my AV / security but all three machines also use Kaspersky and I've no issues on two of the three.

I'm currently running TB ver 102.11.0 (64 bit).

Any assistance and clear instructions would be greatly appreciated.

Cheers

How do I correct my serious error (when tired) in allowing a Thunderbird 'Upgrade' 115.2.2 (32 Bit) Supernova to install on my Laptop (Windows 10 Home, 64 Bit). I failed to read the Release Notes by trusting Mozilla wouldn't issue such a drastic change without Warnings as it was not just an 'Upgrade'! It has screwed up my Set up, Folders etc., completely changed layout, can't find 'Write Message' tab etc. etc . etc.

The previous Thunderbird Version had many problems further introduced by 'Upgrades' but was at least still had continuity with earlier Versions with a functional MMI (man machine interface) instead of all the changes introduced with the 115.2.2, which in my opinion should be withdrawn completely. N.B My experience in Systems Control, as an Air Traffic Control Engineer, we would throw this out as not fit for purpose.

Help Please and explain how can I revert back to an Earlier Version?

In the past two days I've not been able to insert a hyperlink into an email via either the link icon nor the insert navigation.

When I hit either I am no longer able to do anything with the message I am working on it freezes. I am still able to go back to the rest of my mailboxes/folders without an issue.

Anyone know if this is a known issue or what the fix might be?

Thanks in advance.

v91.7.0 on OS X 10.14.6 Used TB for many many years. Have a Charter IMAP email account set up. All of a sudden a good number of months ago, all my emails in my Inbox have a banner that says "This is a draft message" when just clicking on them in the email list.

> https://i.imgur.com/joLqACp.png

Opening any of those mail (which for some reason always opens as Write: mode, whatever that is, not view or reply; not sure what's going on there either) will show a yellow banner at the bottom of the email with the following: "A unique identity matching the From address was not found. The message will be sent using the current From field and settings from identity <IDENTITY> <MY EMAIL>."

Any other folders, like Sent or Saved folders don't show or have this issue. I am not and don't use Unified View. I also have two GMail accounts and neither of them are doing that with their Inboxes.

EDIT: It displays some similarities as the bug here, but not all of them (https://bugzilla.mozilla.org/show_bug.cgi?id=1508153). For example I don't get a double window.

I have two Gmail IMAP accounts configured in Thunderbird (91.12.0). I have subscribed to Gmail's Trash folder on both IMAP servers. One of the accounts shows the trashcan icon for the folder and shows an option to 'Empty Trash' when right-clicked, but the other one shows as a regular folder and doesn't have the option to empty trash.

I've deleted the folder, deleted the folder files, unsubscribed/resubscribed and nothing seems to fix this issue. I've Googled for others having the same issue but couldn't find anything on it.

Any ideas on how to fix this?

For some time I have had the problem of the above error when double clicking to open an email from the Inbox in a new window. No other folder was affected. The problem did not appear when running in Safe Mode, but still appear when running the base install with no add-ons. This problem persisted after completely reinstalling Thunderbird and upgrading to a newer version of my OS.

For a while I was using the right click to open work around. Recently I found mention on another forum of this problem being solved by installing the FolderFlags add on. I used that add on and discovered that the Inbox folder had both Inbox and Template flags set.

Removing the flag solves the original problem for the duration of the session. But closing and reopening Thunderbird somehow sets the Template flag again, recreating the issue.

How can I prevent Thunderbird from changing the Template flag setting?

Recently it doesn't seem as though Thunderbird Filters are working. I thought that "Run Now" on the Filters Dialogue used to work on the one filter which one had just finished editing. Filters that I modified yesterday have not updated my in-box. I did have a Thunderbird crash yesterday while loading a particularly large filter.

Where do I find the filter log? How do I test it? Is this snafu from a recent Tbird update?

TIA.

For some reason after running a Windows 8.1 System Restore, Thunderbird no longer worked. It kept producing the following message: "Thunderbird is already running, but not responding. To open a new window, you must close the existing Thunderbird process or restart your system."

The problem was that Thunderbird was actually NOT running. Nor did it appear in Task Manager so I could end the Task. Restarting the system did not eliminate the problem. Nevertheless, I decided to save the Thunderbird Profile for the email messages that it contained.

I then downloaded and reinstalled Thunderbird and replaced the Profile with a version I had saved several weeks ago. This solved the problem as far as Thunderbird working is concerned. However, I lost all of the pop emails after date of the weeks old profile I had saved. The missing emails were from two pop email accounts.

In the Profile that was causing the initial problem and that I saved, the missing emails appear to be present. However, if I copy the Mail folder from that Profile and replace the Mail folder in the Profile that now works, the emails do not appear. Rather, only the names of the two pop email accounts appear with none of the account folders, i.e. no Inbox, Drafts, Sent or Trash folders and their contents.

Is it possible to copy certain files/folders from the problem Profile and replace those in the Profile that works in order to recover the "lost" emails. Copying all of the content from the Problem Profile simply causes the same issue with the "Thunderbird is already running" message.

I am running Windows 8.1 Pro (64bit). The current version of Thunderbird that is now working is 91.10.0 (64 bit). Assistance to recover the missing emails would be greatly appreciated as some of them are rather important. Thank you in advance for considering my issues.

Somewhen before or with 91.2.1, the default action when opening an existing email became "Edit draft message." (W10 19043, synching to GMail) That setting is nonintuitive and just wrong. A default should NEVER be an action that commits to an irreversable behavior path. Please fix.

This extremely bad design "feature" has apparently been around quite a while and generates exactly the problems returned by a search here on "delete attachments Thunderbird." I first noticed the behavior just about the time GMail introduced two-factor authentication. Maybe no connection there, but ...

Hello, I've been using Thunderbird since it first came out may years ago and have been a satisfied user. Sometime in the past year, after one of the Thunderbird updates, Thunderbird became EXTERMELY slow to open. It takes over a minute. I have looked for solutions here for the past year...no luck (I've read through most all of them here, that have to do with slowness of Thunderbird opening, as well as on Reddit). I've tried basic troubleshooting e.g. clearing Thunderbird cache, increasing cache to huge size. I've seen references to the slowness being related to "multiple calendars". I don't use calendars on Thunnderbird and went as far as to delete/disable the default one that was there. Still no improvement. I know its a Thunderbird specific problem since:

a. I don't have this slowness opening any other program on my Mac (opening it or using it) b. I don't have a problem with performance of Thunderbird once it finally opens c. It all started in 2022 immediately after one of the Thunderbird updates.

I am on: Mac Air M1, Ventura 13.2, 16 GB Ram Thunderbird 102.14.0 (64-bit)

I hate to ditch Thunderbird after using it all these years and being a very early user since it came out, but I am at wits end. Any help is appreciated. Thanks for any help in advance!

I found a few similar problems on the internet but none of the answers can actually fixed my problems. I can only add 1 Gmail account for personal and the Work account cannot be added due error 400. I also have a custom domain account selfhosting so I don't think it is Thunderbird fault.

1. I have no VPN 2. I use no firewall 3. I use the latest Thunderbird 115 4. I made sure to clear caches 5. I do not accept cookies from anysite 6. I always use Mozilla recommend config for Gmail which is SSL/TLS and OAuth2 7. IMAP is turned on 8. This is the link has 400 error (I got this after enter the correct login email), see [1] 9. I have apache2 server for web deverlopment, and there was an answer in here suggested that it might block Thunderbird from receive Google Token. So I disable the apache2 but still nothing change.

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.
