I back up my TB profile every few months. I just went thru the Cox-Yahoo email conversion and I am getting emails. When I did my back up, I noticed in the properties it had one more folder and the files went from 1311 to 2585 files. Is something wrong? Do I need to compare and research what is causing this or just move on!

Hello! We are a real dues-paying member, having made a number of donations over the years. We have been having trouble with emails received from Microsoft-based systems, with the HTML formatting of messages getting lost and the attachment of a winmail.dat file, which we can't open. We tried to use your Lookout add-on, but with all of the permissions that must be given in order to use that add-on, it will not pass our IT security folks. Is there any chance you will be able to improve Thunderbird to read those messages without having to use the add-on? We really hate Microsoft, and would prefer to stay on your team, but we will not be able to unless a solution can be found.

Thanks! Mark

Despite literally hours of frustrating -- now infuriating -- effort, my inbox won't show "from," which was removed by the most recent update. Is this problem fixable? If so, how? (If not, I'm damn well going to dump Thunderbird.)

In the past, I could click on an email address and drag it into a new subfolder I'd made (let's say for emails to a group about baking). Easy as pie!

Sorry for the bad pun.

Now, when I try to click and drag, it will NOT go into that subfolder. I looked in Help and there were answers about csv files, about a horizontal or vertical view, etc. None of that made sense to me.

So I'm wondering if it's still somehow an easy thing to do, to duplicate someone's email in one or more other folders. It seems like it should be! Thanks, Su

At our clinic when we cannot answer client calls it goes to voicemail. The voicemail the should be sent to our email and transcribed, however it hasn’t been. It leaves us with the only option to play voicemails aloud while clients are going in and out of the lobby, which we find unprofessional. Please help us fix this!

I just noticed (after 7 yrs) I have Thunderbird(beta) 32 bit on my laptop windows 10 (64 bit machine) and Thunderbird 64 bit on my desk top Windows 10 (64 bit machine). How do I get the 64 bit Thunderbird on the laptop without loosing all my settings to login to my 4 email accounts?

In my inbox I see a couple of emails that (once opened, or even seeing preview) are not associated correctly to the original email sent or received. It's quite odd as it happened only a couple of times, but even after updating, rebooting and moving these messages, they are still showing the wrong addressee and content.

In the attached screenshot you can see the example. Looking forward to receiving your help. Best regards, Nuno

After some intermittent problems, hopefully solved, I am now left with one main problem. When I send an email to agmail eddress it fails, saying something about SPF having a hard fail and no DDKM, whatever that means. If I send emails from webmail ro my iPad they get through. Can this be solved, please?

I've been trying to get Thunderbird (102.6.0) to filter messages based on message body contents that contain specific URLs (such as "https://docsend.com"), but it's not working. I even tried setting emails to be viewed in plain text (as opposed to HTML), but that also didn't work.

How can I achieve this?

Hi, my Thunderbird has brought down 279 emails from Gmail. I opened Gmail and found the emails properly in the Trash folder. So it appears that Thunderbird is bringing down all folders??? I've been a user for years and never notice downloads from spam or trash before. New change to Tbird? Is there some way to exclude spam and trash folders from download? My version is 115.11.1 (64-bit) TYIA Richard

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.

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.

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.
