"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?

"Sending of password for user joebernard@verizon.net did not succeed. Mail server pop.verizon.net responded: [SYS/TEMP] Server error - Please try again later"

^^This message comes up every time I try to send an email. It can be received outside of Thunderbird and to other addresses.

Right now I'm using 3 different email accounts on Thunderbird. All 3 of them are Office365 accounts. For some reason, 1 of the 3 accounts is prompted at least once a day, sometimes twice a day, to enter my password on the Office365 website popup that is used with the OAuth2 authentication process. It's very irritating, all 3 accounts are Microsoft Office business accounts. What would be the reason why it needs to authenticate daily? Is there no password manager to do this automatically once it's been entered once? Can I pick a different authentication method? What is the correct change to make so I don't have to keep typing in my password every day?

See the previous, now archive post about it.

If this option makes emails sent from Thunderbird to any other email client have arbitrary line breaks where the line changes in the view of the composer. Please explain to me like I am 5, why is this ON by default? I just spent hours wording and formatting a work email vital for my career just to find out it will most likely look like a poem to the person that reeds it. This mailnews.wraplength "feature" looks a lot like is there to signal to other non-Thunderbird users to use Thunderbird. I really really hope there is a good explanation for why `mailnews.wraplength` exists and is on by default.

I have over 35 email accounts, which I use Thunderbird to collect. Love Thunderbird for well over 2 decades!

I am wanting to have 2 of my email addresses to be downloaded before all the others. I have indeed successfully "moved" these 2 accounts to the top of my account list (Shift and mouse). However they are not downloaded in the order of the account list.

How do I accomplish this? Is it possible?

I created a ticket, and it auto-responded to run this by the Volunteer Community. I really want this to be handled by support, but welcome anyone to give me a solid answer.

This there a "Global" Message Filter Rule where you can change an Apply Filter When: to ALL your Message Filters?

Example: I'd like to add "Periodically, every 10 minutes" to ALL my current Message Filters. Currently, it looks like I have to Edit each and every one of them?

Thank you in advance.

When I launched Thunderbird today, it would not connect to one mailserver: imap.mailfence.com. At the same time, Thunderbird said to restart to update to 115.2.2. After updating, it still refuses to connect. There is nothing wrong with Mailfence and I do not find anything wrong with the configuration settings in Thunderbird. I even tried to set up my Mailfence email account again but it failed because it could not connect. Ideas? Thank you.

We had a storm and now email doesn't work. We are a business and have to have email. I've went in and changed the Mozilla password and when go back to email it won't accept it. Emails aren't coming through. Can't sign in. What do I do?

I get the pop up that includes Add Security Exception

 You are about to override how Thunderbird identifies this site.

Legitimate banks, stores, and other public sites will not ask You to do this. Location:

I am in Australia and Optus is my email provider. They have checked all is working at their end and suggest I contact Thunderbird which is why I am here.

Thanking you for trying to help

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?

My many message filters were lost in updating to 115, and it has taken much time to reconstruct the new layout to be usable. If this was AI generated, it is a poor outcome.

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.

Hello. Some of my messages are not displaying in text or HTML as they should. I have tried changing settings to solve this but setting as Automatic or HTML or text, nothing solves the problem. I shall paste a partial email so you can see what I mean (I have deleted personal information):

--=_af7feabd2a6b651b4d3d6af10b5cde55--

Short background: Critically low on disc space. Windows pointed out a potentially extraneous 8.5gb NS3TMP Thunderbird file. Extensive Googling convinced me it would be safe to delete this file. To be safe (HA!) I first copied it to an external drive just in case things went south. They did.

After the copy, I went back and deleted the NS3TMP file. However, much to my horror, instead of deleting 8.5gb as expected, 30.5gb got deleted. After that, Thunderbird would not start claiming my profile was missing.

I copied the 8.5gb backup file back to its original place. No joy. Same message from Thunderbird.

At this point, I recreated my profile pointing Thunderbird to my Outlook email account.

I could now sign into Thunderbird and T'bird started populating the inbox and sent folders, but only partially. Worse (MUCH worse) my critical Thunderbird local folders were nowhere to be found. I attempted several folder recovery procedures to no avail.

I confess, I do not know how Thunderbird works its magic behind the scenes. Were my local folders part of the surprise 30gb file deletion and thus gone for good? Would the original emails that had been dragged into the various folders still be sitting on Outlook's servers?

As I said, totally self-inflicted but hopeful there's a road to recovery.

Any assistance or consoling words would be much appreciated.

My e-mails fail to be delivered to my inbox immediately. They are held up somehow and then suddenly appear days later as a batch of them as though they have been held in a storage box.

When I restart Mozilla Thunderbird, my S/MIME certificate preferences under Account Settings seem to break.

When I initially select a certificate, both the common name/certificate name and the certificate fingerprint appear in the interface (see Working Settings.png). However, after restarting Thunderbird, only the common name/certificate name appears in the interface, and I cannot use S/MIME to sign messages (see Broken Settings.png). When I attempt to do so, I receive the following error message:

Send Message Error Sending of the message failed. You specified that this message should be digitally signed, but the application either failed to find the signing certificate specified in your Mail & Newsgroup Account Settings, or the certificate has expired.

To be clear, Thunderbird has no problem finding and using the certificate right after I set it—the problem only appears when I restart Thunderbird and the appearance of the certificate in the settings changes. The certificate does not expire until April 2025, so this is not the issue. The issue also occurs with another account using a different certificate that is also unexpired.

I am using Thunderbird 115.12.2 (64-bit ESR) on MacOS with Apple Silicon.
