Thunderbird Support Forum

I'm trying to change my signature on an account I've had for sometime. It lets me make the changes I want and when I try sending a message it works fine. However when I close Thunderbird down and re open it, the signature has reverted to the previous version. I can't see any option to save the changes to the account settings so they'll still be there next time.

I've tried it 2 ways - firstly editing the HTML signature text, and secondly attaching instead a signature file. In both cases it works fine until I close and re-open.

On powering up my PC this morning, opened Thunderbird and everything was gone - email settings to my various accounts, settings, calendar, addresses etc nothing is left at all

All I have is a basic screen : "To set up your existing email address" etc

We don't know our password. We are not receiving emails. We have searched our password and it has confirmed it as the same we have written down. However, this does not work. Where do we go from here?

Thunderbird is blocking some outgoing mail. If I start with a file, right click, send to mail recipient; the message is blocked as spam with this diagnostic: Sending of the message failed. An error occurred while sending mail. The mail server responded: Spam detected by content scanner. Message rejected (ID 6661B68A00783926). Please check the message and try again.

But, if I start with Thunderbird Write and attach the same file, there are no problems and the message is sent.

I seem to have lost the search bar that allowed me to find certain emails in specific folders. I am now left with the one that searches all my email folders. Why? How do I get it back?

Hi This morning when I tried to send an email I got a message there was no disk space & so couldn't save copy to sent (I have 848 GB free on HD)

I tried to copy some old sent emails to a folder I've used in the past (old sent) & TB crashed. When I restarted it, many of my subfolders were missing. They are all still showing in Local folders in profile. I deleted all msf files & restarted TB. Nothing.

How can I restore these folders? Hopefully that's possible! Thanks

Hi: I recently set up a new computer. I copied over all the important files I could find before a full hard-drive erase of my old computer. I reloaded Mozilla Thunderbird linked to my Earthlink account. However, upon opening Thunderbird, I discovered that my address book and all saved emails in Thunderbird were lost, and I didn't save them in the Earthlink account itself other than the address book. I do daily backups with Carbonite. Is there a file or files I can look for in my Carbonite backup files that would contain the saved emails? If so, what are their names?

Just got home from vacation and it looks like I left my computer running for a week. Looking for an email and noticed that many, many emails from my saved subfolders are missing. Does Thunderbird automatically archive or something? I have never archived purposely. I need to know whether to use my backup program to try to retrieve these missing emails or to get them from my profile. Instructions in very easy explanation, please. I've tried to search this on the internet, etc. and I'm just lost and panicking. How can I tell if they were archived or not? I've found my "profile" but I can't tell what, if anything, to do from here.

I can receive from outrlook365 but cannot send....... my email shows up(lornea@fowc.ca)as a good account

the outgoing sever settings are correct: they are smtp.office365.com What can be the problem please

Besides this, I have six pop accounts in the one Thunderbird program on my computer and have never had anything in "local folders;" I also haven't set it up for anything as I have no idea what it would be used for. Thank you in advance.

Setting Up Thunderbird for AT&T Email I've used Thunderbird as my email client for years; however, about a month ago it stopped working and now I receive the following message, "Sending of password for user [email scrubbed] did not succeed. Mail server inbound.att.net responded: [SYS/TEMP] Server error - Please try again later". What do I need to do to get things working again in Thunderbird?

Back in 2015 someone asked about the fact that emails are not marked "as read" once opened but I don't think the answer was ever fully given. They were told: "This option has always been available and I use it. via Menu Bar Tools > Options > Advanced > Reading & Display or via menu icon menu icon > Options > Options > Advanced > Reading & Display select: 'automatically mark messages as read' Select: 'Immediately on display' click on OK When you select/left click an email in the list, it will auto open and display in the Message Pane below the list. If you use double click, it will auto open in a new tab or window depending upon what you selected. In bth instances the message will be immediately marked as read." Here's my problem with that .... I don't use the "Message Pane", I don't like it. I have my incoming messages set at "table view" and they are all just listed down the page by date. I don't want to see what's in the email until I actually open it....but, once I open it and read it when I close out of it the email still stays BOLD in the list....this didn't used to happen, once I read the email the BOLD went away. When I use the "automatically mark message as read immediately on display" then new emails are not in BOLD so I can't tell if they've been read or not. Bottom line, is there a way to have messages marked "read" AFTER they are opened WITHOUT using the message pane??

As stated above I can receive email but cannot send email since the last update over a week ago. Also when adding a bookmark it does not show up anywhere that I can find. I seems that I have lost some bookmarks and now it shows two bookmark menu's.

Thunderbird release notes have a web feed: https://www.thunderbird.net/en-US/thunderbird/releases/atom.xml

Do Thunderbird beta release notes also have a web feed ?

My wife and I have used cox.net email accounts for a number of years. Just recently Cox.net moved their email accounts to yahoo.com. We've had our cox.net email accounts on Thunderbird for years, but now it doesn't get our emails because of the transfer to yahoo.com. We don't like yahoo. Is there any possible way to get our cox emails from yahoo to Thunderbird? (our email accounts didn't change).

I've been using TB for years. I don't mind using google calendar, but contacts? This window has been popping up today for no apparent reason. If I dismiss it, it comes back in a few minutes. It seems to be a TB process. I'm on Windows 7. I do have W10 & 11 on laptops, haven't checked yet to see whether this nastiness occurs on them.

Help! My computer was stolen or lost in a recent move. I cannot remember my passwords because I had them all stored on Dashlane. Both Thunderbird and Dashlane (and every other site I need to access) sends a verification to my email that I cannot access. I truly had everything in my life on this computer so I cannot access my bank accounts or credit cards either. There does not seem to be anyway to speak to a person because it's a little confusing. I keep going in circles trying to rectify this situation. Although it sounds like it could be a scam, trust me it is not. I have used Thunderbird for many years.

Any assistance will be greatly appreciated.

Thank you!

I see that I can check "email me when someone answers the thread. Unfortunately it puts me in the same position - someone will email the address I can't access. I have a new address, bradlang8919@gmail.com if someone could send the answer there.
