Thunderbird Support Forum

I would like to know how I may transport Thunderbird from an old computer to a new without losing data. The old computer still is working. I do not have gmail, though I am considering going over to it.

Note: For some reason, I cannot check the box below, requesting that I receive an email when someone answers the thread. Please email me when someone answers the thread.

This continues to be a problem in version 115.12.2. It seems to happen only with older events rather than current ones. Clicking the X closes the reminder but it pops up later. I tried changing the event to turn off reminders but that didn't work. It doesn't accept the change. The only permanent solution is to delete the event from the calendar. I see this problem goes back many versions. It's time to fix this.

I composed an outgoing email message that I wanted to keep for future use, and saved it as a Template. That not only saved it under the unified Templates heading, but created a second appearance of my main email account with its own Templates subfolder. At that point I decided I really didn't want to keep it after all, so I deleted the message, but the second Templates folder didn't disappear; its still on the tree list as an empty folder. Right-clicking that folder doesn't have a Delete function, but it does present a Repair option, but running that doesn't help. How do I get rid of that unneeded individual email account listing and the empty Templates folder?

After updating to Thunderbird version 115.12.2(32 bit) two days ago, I can no longer send emails. I get an error message "Authentification error (VM401)" I use Virgin Media. I can receive emails OK. I have not changed any server settings for a long time. I have been in touch with Virgin Media, they say the problem is with Thunderbird as I can send emails from on their one line system. I can also send emails from my Android phone. Any help would be appreciated.

I know this problem has been discussed extensively, but I can't fix it even after reading the previous posts.

I have an institutional email address that uses outlook.office365 server and mandatory two factor autentication. I had my Thunderbird setup with this, which suddenly stopped working one day on my office PC. I updated Thunderbird to the newest version, but the issue pertains. Currently I'm running Thunderbird 115.12.2. on a Windows 10 machine.

When I try to fetch my emails from this server, a popup window appears that asks for my institutional login credentials. When I enter them, a second window appears, asking for the two factor autentication. However, this window seems to be corrupt, as it does not contain any information, and and it's impossible to type in verification code, as there's no input area at all (see the first picture - note that I'm using a localized version of Thunderbird).

When I click on Privacy and cookies in the right bottom corner, then two lines appear (although without any labels), where I can type in my verification code (I guess that it is the second line, because it shows dots in place of the typed characters, as for passwords). A screenshot of this window can be seen in the second picture.

However, after typing the correct code and clicking on the grey button, the first window reappears, this time with my email address that keeps flashing forever and nothing happens. It does not even matter if I type in the right verification number or just anything, it produces the same behaviour. As a result, I can't log in to my mailbox, which is operational, because I can log in there through the web interface of outlook, and also from my laptop using Thunderbird 78.14.0. I also made sure that the server name and authentication methods are correct (outlook.office365.com, port 993, SSL/TLS, OAuth2).

Do you have any suggestion how to solve this issue?

Many thanks.

Verzenden van het bericht is mislukt. Er is een fout opgetreden bij het verzenden van e-mail. De mailserver antwoordde: Unable to relay without authentication.. Controleer of uw e-mailadres juist is ingesteld in uw accountinstellingen en probeer het opnieuw.

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

After years of working fine, this message has started appearing whenever TB tries to retrieve messages. I've checked that there's enough space (there's many GB free). I've checked the authorisations of the email folders, they're all fine (Full Control in all cases). I found an answer in a forum suggesting that a rogue antivirus might be the problem, but I'm only using MS Defender.

In desperation I removed the entire Roaming/Thunderbird folder, uninstalled TB, reinstalled it (version 115.12.2), created a new profile for my email address (it's a Yahoo email address, and I can retrieve the emails directly through the Yahoo Mail website with no problems). But I'm still getting the same error message. TB tries to retrieve the messages, it says 'Retrieving message 1 of 105' for several minutes, then the error message popup, and nothing appears in the Inbox. (105 is all the incoming messages as of now since this started happening).

I'm completely stuck. Any suggestions?

I occasionally get a Authentication Failed to Server (Outlook.com) and when it occurs it continues for 1-5 minutes then goes away again.

Is there any error logging proceedure that I can set up to see what the exact issue is?

I've tried running a parallel alternative email client (eM Client) and that doesn't seem to suffer in the same way, but I much prefer Thunderbird so would like to find out what the problem is.

Attachments in pdf format are covered with green color. The color disappears, for example, when I open printing setup window. I have arleady repaired the folder and fully reinstalled thunderbird. Do you have any ideas how to repair it?

Recently switched from Outlook to Thunderbird, however still have Outlook to make sure Thunderbird is working the way I want to.

However any emails that I am sending - whilst appearing in my Sent folder in Outlook, aren't in the same folder in Thunderbird. Strange thing is however, if I use the search bar, it DOES find the email, and says it is in my sent folder.

I've tried sorting by name, by date, by anything I can think of, but I can't find these emails in the sent folder.

The only thing I can think of, is that the emails have not been delivered - even though sent - because when testing it out with a separate email address that I have, the emails appear fine.

Any ideas anybody?

I would like to remove the newly added listing "Local FOlders" from the Folder Tree and restore the Local Folders listing that was moved to the bottom (below All Folders) to its proper place, namely Above Local Folders. This group displays Sent Copies which I use frequently. The newly added 2nd display called "Local Folders" does not disply "Sent Copies" when I click on it in the folder tree. Thunderbirfd decided to move my original "Sent Folders" display to the bottom of the tree when updating to the latest version last night (early morning hours of 6/26/24). I run thunderbird in Windows 10 Desktop on Lenovo w530 using wired internet connection.

Hi!

What is the way to tell thunderbird to index IMAP folders in global-messages-db.sqlite which are not stored locally?

And a more generally, how does this part work, message indexing and remote IMAP folders not stored locally? Here, after removing the database, thunderbird indexed only some very limited set of IMAP folders in the Gloda, but not all of the folders, despite all are checked for "Include in global search". Or maybe it didn't even index whole folders, - I can't say for sure.

Thanks,

I have Thunderbird version 60.9.1 running on my window 7 64 bit computer. I have kept this old version, as an add-on that I like / need (Theme Font & Size Changer) said it would not be upgraded for later versions of Thunderbird at the time (that I did not like the font size options available at the time).

I have just received an email claiming to be from Microsoft about changes to the way you will now need to get access to Hotmail and Outlook email accounts (Modern Authentication Methods now needed to continue syncing Outlook Email in non-Microsoft email apps). https://support.microsoft.com/en-gb/office/modern-authentication-methods-now-needed-to-continue-syncing-outlook-email-in-non-microsoft-email-apps-c5d65390-9676-4763-b41f-d7986499a90d

To your knowledge, is this message legit and true?

Are the instructions correct for my older version of Thunderbird? If not can you provide correct instructions?

Alternatively, does the latest version of Thunderbird now support the font size changes that the add-on provided and Thunderbird did not provide at the time. If so, I can update to the latest version of Thunderbird.

Thanks,

Brian.

ps Do you do a Thunderbird version for Android?

pps this is what I need on the Theme & Font Size Changer: (see file attached)

PLease assist After the last update 2 days ago,All of my Sub Floders have disappeared How Can I have them shown again????? It is extremely annoying not having them as I use them Constandly daily PLEASE HELP Thanks Darryl.

I'm grateful that I've been able to use Thunderbird for free up until now. I wouldn't mind making a small donation. However, Thunderbird's email service is currently unavailable. Received emails are not displayed in the inbox. All previous history has also been erased. First of all, I would like your cooperation in fixing the current problem and restoring the system to its previous state. I will make a donation as soon as the system is restored. If the system cannot be restored without a donation, you can make a donation first. I look forward to your reply.

Using TBird 115.10.1 64-bit on Windows 11. For ease of reading text in mail I am composing, I would like to select a large font size. In Settings | Fonts I chose Arial 18; but for some reason I get a small monospaced font whenever I start a new message. I can enlarge it with Ctrl-Plus, but it reverts to its old ways for the next new message. How can I make the change stick?

I love Thunderbird and it has replaced Outlook (classic) for me, but there's one feature I miss, AutoArchive.

In Outlook (classic), emails older than x days can be automatically moved out of the server folders and into local folders, freeing up server storage space and negating the need to pay for additional cloud storage.

Thunderbird has the ability to select a group of messages in any folder and right-click > Archive (move) them to the matching Local Folder: perfect! But manually selecting multiple messages older than x days in multiple IMAP folders and selecting "Archive" is a chore too far.

Thunderbird should natively have the ability to (optionally) iterate across all IMAP folders and "Archive" any message older than x days, according to the Message Archives setting in Account Settings > Copies & Folders. The Disk Space setting in Account Settings could be an ideal place to add an "Archive messages more than x days old" option, since it already has a "Delete messages more than x days old" option.

Note: I know about the AutoarchiveReloaded add-on, but for something as important as shifting emails around with the possible breakage that could occur, and the possibility of the add-on being discontinued, native support would be very much welcome.

Another note: this has of course been raised on bugzilla,[1] but it's a 15 year old bug and seemingly unlikely to come to fruition.
