Thunderbird Support Forum

I started Thunderbird yesterday and apparently did not recognize the profile. It required me to completely set up a whole new account for my emails. Consequently I lost a number of important emails. How can I get it back to my original account? And, for future reference, what is the best way to back up the emails in a manner that PDF or microsoft can recognize the format? Please advise.

I am considering moving to Thunderbird from MS Outlook. I want the rules I have already setup in Outlook to work in Thunderbird. Is this possible & if so how do I make it work.

Would you please help me permanently remove cache2 folder from Local Folders please. I'm using Thunderbird 115.12.2 (64bit) on esr channel with Windows 7 Ultimate Service Pack 1 OS.

I don't want Local Folders / Cache2 folder (or incidently Inbox, Drafts, Archives, Junk, Deleted and Outbox) but Thunderbird highlight - right click - delete button doesn't get rid of it. I can temporarily delete the Doomed and Entries sub-folders with right click - delete - delete folder but they move to Deleted folder where once again they can be deleted the same way but when restarting Thunderbird they are back under the cache2 folder again.

Even after exiting Thunderbird and directly deleting the cache2 folder(s) in system AppsData - Local and Roaming Thunderbird profiles the cache2 folder (with persistent sub-folders) returns to my Local Folders when restarted.

If ignored I eventually end up having a cache2-1 folder etc.

i have no memory of my password for email ,there are two emails , [edited] @eaglevalley,net and [edited] @gmail.com can you text me answer at [removed] 0r [removed]  ?

Recently I've had problems with the SMTP server refusing to send my e-mails, I am still being able to recieve them however. When choosing to enter a new window the window where you should put your passwords appear and dissapear at the same time. I've never experienced this kind of problems before. I even removed the account and the smtp account and re-added them back again to see if it would help but to no avail.

I am following the article from Mozilla called Microsoft OAuth Authentication and Thunderbird in 2024. But still it won't work.

Some of my emails are hidden in threads from previous conversations and not showing up as the last email received. If I am not expecting an email then I may never see it unless I happen to open up a previous that could be weeks earlier. I hate this and cannot conduct business when I can't see emails coming in . If someone is replying to a previous email , I may never see a new conversation. Only if someone sends an email that is not a reply am I guaranteed to see it. How do I fix this

Without notice, Thunderbird today required me to sign-in to my Google account and then produced a window in which it said it wanted to access to my mail, contacts and calendar; in order to compose, send, share, delete permanently, among actions on my personal content. I tried to "Deny" (see below) but the window just returned and returned and could not be deleted. (see "Uploaded images", below for the content of this window).

Is this a scam? Or the result of a hacker?

Suddenly I cannot send emails. I can receive emails. I have checked my account settings and they are correct as follows: Charter Communications mail.twc.com port 587 Starttls normal password ggordets@san.rr.com. I contacted Spectrum and we proved that the problem is not them by initiating an outgoing email to myself using webmail. I even tried uninstalling and re-installing Thunderbird. As indicated above my email is ggordets@san.rr.com

Thank you. P.S. My operating system is Windows 10.

Our small business has a handful of Zoho email addresses that we use via Thunderbird on MacOS computers in our office. The computer I am using only has some of the email addresses listed in Thunderbird, and I am trying to add the rest.

Once all requested data is entered in the "Set Up Your Existing Mail Address" screen, we receive the error message: "Unable to log in at server. Probably wrong configuration, user name, or password." All of the data is correct, and I have tried this process different weeks to see if the issue will clear on its own, but no. I've attached a screenshot of the error message.

I have tried this with several pre-existing email addresses and it's giving me the same message, although it did allow me to add one address recently. That newly added, previously existing address is now somewhat accessible via Thunderbird, but every time we open Thunderbird it says "Login to server imap.zoho.com with username shipping@jadeandpearl.com failed." I can access the inbox and other folders of this account in the Thunderbird desktop app, but it is not currently showing new email.

Thunderbird version: 115.12.1 (64bit) MacOS: Sonoma 14.5

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

Greetings, recently our pc was attacked ,malware. A new windows program was installed. This resulted in some apps being deleted. One of which was the Firefox email. Inspite of many attempts to reinstate it I have had no success. There is great difficulty in finding what to do to reinstall. There are assumptions that I have particular information. Other than our 3 email addresses we do have any code numbers or passwords, as these to were also lost. As it has been several days since the "repair" the inability to access Firefox with historic emails is now creating a number of serious issues. I need urgent help in reinstalling our Firefox email. My inability to find that one person who I know can help is out there. The FAQ were of no help. The request how to reinstall Firefox does not appear to be a FAQ. Ross.

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?
