Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) mail.cp.co.id failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.

Since Thunderbird was upgraded to 115.10.1 (64-bit), it now fails to send SMTP messages with the following error.

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) ***.mail.pairserver.com was lost in the middle of the transaction. Try again.

This affects all six(6) accounts in Thunderbird, all of them can receive and edit e-mail messages; however, all of them fail to send e-mail messages.

Prior versions of Thunderbird have worked with this configuration for many years.

Other e-mail clients such as Evolution do not have this issue and I have confirmed with my provider that Thunderbird is no longer sending e-mails.

Any thoughts on how to roll back Thunderbird until this issue is resolved?

TB won't set up on Yahoo mail. Spent about 3 hours on the phone with one and sometimes two Yahoo techs and giving them total access to my computer so they could set up TB but could not get it working. It was eventually suggested I contact you folks, so here I am. When sending an email, it just keeps running like it's sending but doesn't stop. Eventually displays the following:

Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) smtp.mail.yahoo.com. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'.

The techs and I went around an endless loop of re-entering PW and checking authentication settings. Any suggestions?

I updated Thunderbird to version 115.11.0 (64-bit), in the old version that I had when I clicked on an email with threads in a closed state, I could see in the email display box the initial text of each email in the thread with the sender's information and more, in the new version I don't see anything, the display box remains blank. Is this a bug, or do I need to change it in the setting?

Just a few days ago, one of my email accounts is unable to retrieve emails and it has the following error message:

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 installed the latest updates but still having a problem on that one account. Other accounts I have on the same server has no problems retrieving the emails so it has nothing to do with "disk space". All settings in the accounts are identical except for the email address so it must have something to do with TBird itself. I know it's not the email server as I can log into those accounts using the browser on their website. Thanks!

Upon startup, top email displayed is the 2nd email present in the inbox. If 1st email is one at top when leaving TB, next startup will show the 2nd email on top. You can then scroll up and see the top one. Likewise, if a new email come in, it also shows the one below that as the top one and must scroll up to see it. No emails are lost, just a display thing. Don't recall which version this started, but it didn't use to do this.

I am migrating from Thunderbird to Office 365. I have moved the email by putting the Gmail details into Office 365. However could you please advise how I can migrate Tasks , Calender and Contacts from Thunderbird to Office 365 without having to pay for an Mbox to pst conversion tool.

I have Thunderbird installed on my laptop running Fedora 40 with Gnome on Wayland. I have two monitors with different resolutions.

The laptop monitor has a resolution of 1920x1080 whereas the external monitor has a resolution of 1360x768.

Thunderbird display fine on the main monitor, but when I move it to the external display, everything becomes huge and unusable.

I don't want to scale things in such a way that I have the opposite problem, that is things are way too small on the laptop monitor. Is there a way to have Thunderbird scale properly on the external monitor to have it maintain the right proportions on both monitors?

Thunderbird 115 included in 24.04 LTS installation.

My profiles are located on the SD card working well on other two laptops running ubuntu 22.04. Swap SD cards between two laptops is my way of working with Thunderbird since 13.04.

After installation 24.04 LTS (and Thunderbird 115 included). Following the instruction for adding old profile to the new Thunderbird. Help->thunderbird information->about:profiles. Creating new profile. 1) Using the function CHOOSE FOLDER indicated the path to the profile /media/VB/AB49-E208/Thunderbird profile 2) The path to the folder shown by Thunderbird is different (and strange): /run/user/1000/doc/58235/Thunderbird

When looking into the directory tree the folder is empty (obviously). Thunderbird therefore cannot reach the profile located on SD card and doesn't work.

QUESTION: Is there any way to overwrite the profile folder path in Thunderbird 115 ?

I sort my emails in date order, newest at the top. Recently, new emails have started to arrive at the bottom of the list, until I exit the folder and return, or re-sort the Inbox. This seems to be a new bug. Why is it happening?

Thunderbird keeps suggesting to use the Filelink feature for sending large files. And I am quite on board with that idea. However, the only way I can officially share large files with the industry partner is a Kiteworks platform, that is configured to only allow SFTP and the webclient.

When clicking on "Find more providers", the only provider that isn't specific to a business like Dropbox is Webdav.

Is there any way to use an SFTP server for Filelink?

One of my two gmail accouns has suddenly become impossible to access (cannot receive, cannot send). T'Bird produces an Authentication has Failed notification, after a Google Window headed "Sign in to Mozilla Thunderbird Email" which refuses to go away. Clicking on the 'help' or 'privacy' options in that google window produces no more than a blank window but then "Sign in to Mozilla Thunderbird Email" reappears a few minutes later. My other gmail account doesn't have this problem, so I assume it's not gmail but it's T'Bird.

What's going on?

(BTW signing into this Support resulted in an email "New sign-in to Mozilla Support" warning "New sign-in to Mozilla Support to Firefox on Windows 10". Trouble is, I'm on Windows 11. Trivial maybe, but telling maybe.)

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,

Using Thunderbird version 115.11.0 (64-bit) with Windows 7 OS and THREADING TURNED OFF.

When I receive a second reply to an email I've sent via one of my email service providers that uses an outlook365 server, my thunderbird view hides it beneath the first reply unless I manually intervene by clicking on the "greater than" sign associated with the first reply. When I do click on the first reply the greater than sign spins clockwise 90 degrees and the second reply appears below the first as if it were in a subdirectory.

The above behaviour is very inconvenient because I am prone to missing the second reply and have trouble anticipating its existence. Admittedly the unread second reply does change the first reply's text property to "bold" but I much prefer to see the new message without having to manually click on everything bold to check.

Another email service provider I use also has an Outlook365 server but second replies to emails are not hidden in its associated thunderbird inbox?

Can anything be done in thunderbird to stop this "feature" or is it absolutely fixed by service providers?

Since starting my Win 10 Pro computer today, Thunderbird 115.4.2 (64-bit) has been "dead in the water". When it's launched, it posts the customary "Downloading Message 1 of [N]" status report, but then hangs right there, takes 3 or 4 minutes even to (re-)populate the tabs and panes that had been open, doesn't get past the alleged first new msg even in 15 or 20 minutes. When it does populate the Inbox pane, it shows no messages newer than last night just before shutdown. Very sluggish response to cursor, too: for ex. 30 seconds from clicking on a msg title in the Inbox pane to displaying that msg, even longer to bring up Help/About (with "Not Responding" shown in its title bar.)

  I get my mail through gmail's IMAP server but prefer to use Tbird's interface . Thinking there might be something evil about the first msg that was waiting to be downloaded, I used gmail's web interface to review everything new since last night, deleted several msgs that had attachments, then started Tbird again.  No change.  Can't even get Tbird into the "Work offline" state because it attempts download-of-new-msgs immediately after being started.
  The only consistently effective way I have found to STOP the hung Tbird is through (Classic) Task Manager's "Processes" list, which usually shows five or six "thunderbird.exe" instances.  After selecting whichever has the largest memory allocation I click on "End Process."
  This all "feels like" a bollixed internal state.  Does Tbird store internal-state information in its own file, or is it buried in the Registry?   If I attempt restoration from a backup, which files are needed; or is that unwise?
 I see there is a mid-April update available to 115.10; would installing it reset current messed-up internal state, or will that already messy situation prevent the update?   Is there any risk of losing my Inbox, Sent, etc contents?

Thanks!!!

Hello, my Cox email account was migrated to Yahoo mail. I can receive emails but now I can't send emails from Thunderbird. I've triple checked server settings. Please help. Thanks-Vince

This is the message I get and it does this with all email addresses.
