When I opened Thunderbird to get and read my new email I received this error message after I could see that Thunderbird had found new messages.

"Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox."

I checked the hard drive space on all of my hard drives and I have GBytes of space and in PREFERENCES for the hard drive, WRITE is allowed. In fact all items listed in Preferences is set to allow.

I've rebooted the computer and even had Windows check my hard drive for errors and it found no problems. What do I now need to do? Thank you. Fred Berney

Sehr geehrte Damen und Herren, als langjähriger Nutzer Ihres Email-Programms erbitte ich Ihre Unterstützung bei der Lösung fol-genden Problems: Seit Jahren verwende ich Norton 360 PREMIUM als Sicherheits-Software; Domain und Emailadresse sind von strato. Das funktionierte immer ohne Probleme, auch nachdem ich vor einigen Monaten entsprechend Ihrer Empfehlung die Authentifizierung der SSL-Einstellungen vornahm. Doch bei der jetzt von Norton empfohlenen Installation von Norton Safe Email erschien nach Eingabe meiner Emailadresse <rb@roland-buchwald.de> der Sperrhinweis „Dieser E-Mail-Anbieter wird nicht unterstützt“, so dass der abschließende Download der neuen Programm-Komponente nicht möglich war. Ich wandte mich deshalb an Symantec Norton und erhielt die Antwort: „Es tut mir wirklich leid, Ihnen mitteilen zu müssen, dass Ihre E-Mail-Adresse unser Norton Safe Email nicht unterstützt, da Ihr E-Mail-Anbieter nicht mit unserem Norton Safe Email-Programm kompatibel ist.“ Kann ich das Problem in den Konteneinstellungen beheben oder was empfehlen Sie mir? Ich bitte Sie, mir per Email, online oder telefonisch unter 0309712945 bei der Lösung des Prob-lems zu helfen. Zunächst vielen Dank und freundliche Grüße! Roland Buchwald

In Thunderbird I see two methods of accessing/editing SMTP settings for email accounts.

1. Using the "Outgoing Server (SMTP)" which displays all the email accounts in a list. You then select one and click "Edit" to view or edit it.

2. On each email account page there is an "Edit SMTP server" button. Click that to view or edit the SMTP settings for that account.

I'm seeing two problems:

1 - The settings made using #1 above don't carry over into what I see using #2 above.

2 - Using method #2 above, changing the SMTP settings for my newest email account also changes the settings (seen using #2 above) on one other email account. And vice-versa.

What could be causing this?

Hi How can I Select all emails from a sender. I'm looking for a similar functionality to Outlook where you right-click on an email > "Select all messages from this sender" so I can move them out, delete them, or do whatever.

It looks like this is missing from your application. If I can't use it, I have no other reason to use TB.

Thank you B

Am a long time user of Thunderbird and I received error msg: "Unable to write to the mail box, make sure the file system allows you write priviliges, and you have enough disk space to copy the mail box." I can't figure out how to do this. I finally deleted my account and reinstalled Thunderbird and continue to receive this error message. I can't receive and new message on my computer and using gmail on my phone. my email is rstoma@astound.net. Thanking anyone in advance

I have several errors associated with the unified folders display. I have 6 email addresses coming in to Thunderbird. 3 are IMAP and 3 are POP. I have the POP addresses consolidated into the "Local" Folders Inbox, Sent, Trash etc. In the "All Folder" account views, the Local folder correctly displays one Inbox, one Sent, one Trash etc. The 3 POP emails accounts are being consolidated appropriately. However,in Unified folders, the Local folder as well as all of the individual POP addresses are now listed for the Inbox, Trash and Junk folders. There is now no consolidation.

Also, the Unified folders themselves are extremely slow in working. Accessing the properties for the Unified Inbox, Trash or Junk folders results in a long wait with Thunderbird entering a not responding state. Right click operations on the unified folders do not work at all. I cannot select properties, I cannot mark as read, empty or otherwise manipulate the folder. I must go to the individual accounts to manage any folder content. Which I would think makes the whole concept of Unified folders moot.

I am not at all certain what may be the root cause of this rather longstanding problem. I have deleted the smartfolders directory, have deleted the virtualfolders.dat and foldercache.json and foldertree.json files. Nothing seems to work.

Any suggestions?

Something has broken mailmerg

An unexpected error occurred Help: Homepage and Changelog

Ubuntu 24.04 NOT snap. Thunder bird 128.5.2esr (64-bit)

Mail Merge Create and Save or Send Multiple Individual and Personalized Messages from a Draft Mail Merge 10.5.0 is fully compatible with Thunderbird 115 and Thunderbird 128.

I run Thunderbird, Thunderbird ESR, K-9 or Thunderbird. Windows 7, 10 and 11, Linux and Android 5.1 and 12.

My desktops all have a gmail and yahoo.co.uk email addresses. Each account is linked to there respective contacts server but all my contacts are in one gmail account which has lost most of the contacts in recent months, that is, only the contacts that I have used recently are still present. So I have been investigating the settings and adjusting in some cases.

Some instances all the account are still linked to the contacts servers. Other cases only some of the accounts are still linked and I want to re-establish the other accounts that have become local accounts, these still have my full complete address book.

Lastly between K9, thunderbird, contacts google I don't know what went wrong but I like advice on how to avoid the problem in future. In the meantime seasons greatings, no hurry my christmas messages will have to wait.

I setup my account it worked well, I changed my office365 password. I was prompted to login with Oauth2, and it worked. However, I can receive emails, but cannot send emails. I get a notice that my password is wrong when I come to send emails. It just happens because of the password change. No matter what I do I cannot find where the Oauth was saved for smtp. There seems to be a desync, where the password updated for the Incoming server, but never lets me or updates the Oauth for the smtp server. Any thoughts?

Deleting saved passwords, just gets me to do Oauth2 for the incoming, it never takes effect on the smtp server.

Using thunderbird to connect to the mail server outlook.office365.com with imap gives the message "user is authenticated but not connected" . I have 2 accounts on this server and one works fine and the other gives this message. This occurs on both Windows 10 and Windows 11. Latest version of Thunderbird is being used. Any help would be appreciated.

Many times when I am forwarding emails or copying and pasting text from an outside source, the spell check will choose a word like "isn't" and highlight "isn" as a misspelled word. This has happened with a number of different contractions.

Additionally, it will pick parts of an abbreviated name in someone's email address in the To: field as a mistake. I do not have the time or desire to constantly, go through a long email and choose 'add to dictionary' or click ignore. Why is it even looking at parts of a contraction, and it should be ignoring the To field altogether.

Is there something wrong with my version or is this how it operates? My TBird is up-to-date: 128.5.2esr (64-bit).

I am having a problem syncing my Thunderbird folders with iCloud. Every time I have to explicitly check that I want to subscribe to all IMAP folders in my iCloud account. Then after a short while a lot of folders get unsubscribed and I have to subscribe them again. I have experienced this instability with both Thunderbird and Betterbird as well as on Windows 10 and Pop_OS! 22.04. More people have reported the same issue, but no solutions have been shared:

Does anyone know how can I fix this?

I just migrated my Thunderbird from my old MacBook to my new Mac Mini. I tried following the official instructions and the instructions in the linked thread, but I experienced the same problem the other users did— that Thunderbird, on the new Mac, would act as if it was setting up a new account, even after replacing the entire Thunderbird folder in the user's Library folder. With some investigation, I was able to detect how to fix the migration, though I can't tell you why Thunderbird behaves this way.

Here are the instructions I followed: [https://support.mozilla.org/en-US/que.../1397228]

The process of copying the old Thunderbird is correctly described. However, there is still some funny business on the receiving end.

What I determined was that Thunderbird, for whatever reason, wasn't reading the information in the profiles.ini and installs.ini in a way that launched the migrated installation. Instead, it still created a new installation and a new profile and overlaid those on top of the information in the migrated files, making the newly created profile the default and ignoring the migrated profile when launching.

In order to correct this, I needed to manually edit the profiles.ini and installs.ini file (in a simple text editor) to use the NEW installation but substituting in my MIGRATED profile for the newly created one.

I'm sorry I didn't take screen shots before deleting the files, but the important thing is to edit both files so the both are using the NEWLY CREATED installation ID but that both files only reference the OLD profile ID (deleting all other mentions of the newly created profile and deleting mentions of the old installation ID. This is just a copy/paste operation.

I've attached screenshots of mockups of what my new profiles.ini and installs.ini look like. The important thing is that both have the NEWLY CREATED installation ID (not the one copied from the old Mac) with the OLD profile ID.

i'm using:

Thunderbird 128.5.2esr (64-bit) Kubuntu 24.04 KDE Plasma 5.115.0 Qt 5.15.13

when i get attached files, like .jpg, .png, or .pdf, i can see that the message has an attached file, but thunderbird no longer opens those files, or knows how to make other applications, like okular, gwenview, or inkscape open them. this USED TO BE a standard feature.

1. receive an attached file: FILE-NAME.pdf

at the bottom of the window is a bar that says "1 attachment: FILE-NAME.pdf 3.8 kB"

2. click on FILE-NAME.pdf

EXPECTED RESULT: FILE-NAME.pdf opens in okular

ACTUAL RESULT: nothing

3. alternate-click on FILE-NAME.pdf and choose "Open" from the context menu

EXPECTED RESULT: FILE-NAME.pdf opens in okular

ACTUAL RESULT: nothing

4. alternate-click on FILE-NAME.pdf and choose "Save as..." from the context menu, and save the file somewhere obvious.

5. navigate to somewhere obvious, and open the file

RESULT: FILE-NAME.pdf opens

i looked at "Settings -> General -> Files & Attachments" and confirmed that "Portable Document Format (PDF)" is set to "Use okular". i also deleted, and re-added "Portable Document Format (PDF)" from "Settings -> General -> Files & Attachments" with no change in the above reported behaviour.

I just upgraded my desktop pc from Windows 10 to 11, and before the upgrade I used the Tools Export function to export my complete Thunderbird profile, so I could import it after the upgrade. Unfortunately the export file cannot be read on my upgraded pc using the Import function - Thunderbird gives me error messages every time, that suggest the exported folder might be corrupted or invalid.

My IMAP emails are fine, as I have set those accounts up from scratch and the folders have now populated with all the emails - the problem is all my filed emails, dating back many years, which were all stored manually in a filing system under Local Folders.

I tried manually copying across the individual files from the extracted back-up folder into my live Thunderbird profile and then reopened Thunderbird...which worked to some extent...as in, all the folders are there, but no emails are showing! It shows no messages under each folder, even though if you look under the Profile you can see that the email files exist.

I tried various ways to bring them in, including zipping one of the folders and trying to import from the zip file (which also brought in a folder but no emails) but even though the email files are clearly there under my profile, Thunderbird shows 0 messages in all my Local Folders. It's as though it is unaware the files exist, so I suspect it needs them to be formally imported somehow?

I would hate to lose the emails, as they document important information and purchases etc over many years, along with archived emails for my charity work, social events, etc. As I said, I can see the files are there but simply copying the files to my profile has only worked to the extent the filing 'structure' is visible, Thunderbird doesn't display any of the emails.

I have included two images...one of my Thunderbird Local Folders as they currently look, and the other showing the backed up files existing in my Profile, which I hope are helpful.

Can anyone help please? I am running a desktop PC on Windows 11. Thanks, David.

I am having a problem when connecting to my employer's office 365 server. I'm getting an error that says the current command did not succeed. User is authenticated but not connected. If I connect to the same account in Outlook, it works as it should. Everything was working fine until about a month ago. I had not made any changes to the configuration, except for possibly a version upgrade. I am getting same error on all computers running Thunderbird. Two are Windows machines, one is a Linux machine. I am currently on Thunderbird 128.5.2ESR. I have seen solutions on Google, and I have tried deleting the account, recreating it and changing the IPV6 DNS setting in config editor to true. Has my employer changed something that is not going to let me in? I really hope not, as I cannot stand Outlook. Even more so with the new Outlook. Thanks much for your help and advice.

Hey,

I am running a new Mac and when I am composing an email and click attachments, the Mac finder (file system) window pops up, but all options are greyed out for 5-10 seconds before I can navigate. This is not the case in the native one if I open it normally outside of Thunderbird.

I have reinstalled and tried all the normal steps, and the issue is still persisting.

I would appreciate any help or having this escalated to the team.

Thanks!

I reloaded thundebird three or more times and it ask me to give my name email and password then says no good all I want is to get to my folders to access my history
