With about 60G of accumulated e-mail in several Microsoft accounts, I moved all accounts into T-bird and put most in local folders. This somehow became over 600G in size. Everything works and compacting seems to be getting done since it's been working some weeks now. Yet this ten-fold increase in size is unwieldy and very difficult to backup. Perhaps related, I notice that M'soft's "new" free Outlook app is present and perhaps running on this computer. And all the e-mails I send from my main Hotmail account are listed twice in the T-bird sent folder. About half of the times I start T-bird, I get a message saying that login to server outlook.office365.com with username xxxxxxxx@hotmail.com failed; the other accounts never do this. T-bird offers to retry, but that usually ends with a repeat of the same message. I've learned that if I let it open, with time, the e-mails do appear, though I don't know how or why. I've also been using Libreoffice successfully for months now though I doubt that anything to do with this. T-bird nicely solved the original e-mail oversize problem I had with Microsoft's size limitations and I'd appreciate advice on how to deal with what's happening.

I have always kept old emails in the LOCAL folders for security reasons not having all my info on a server somewhere that could be comprimized/stolen/scammed. I am now on Yahoo and have heard security is not the best so I am not sure I want to put all these files on their servers. Now, however, as my PC is getting old I am afraid it could crash, I assume I would loose all those emails-correct?. If I go into my TB Profile and find the Mail/Local Folder I can copy and paste it to a flash drive. Would that be the recommended way to back up? If I did this process a month from now would it, like a file, ask me to overwrite what is already there and add anything new? If my PC did crash, could I do the reverse and copy and paste that flash drive Local folder into my new TB profile? Thank You.

I've configured an external gpg key for use in Thunderbird, but I'm unable to decrypt an encrypted message sent to myself via thunderbird. I've attached the error thunderbird gives me.

Sending a normal email, a signed email and an encrypted email works just fine. Verifying a signed email also works fine.

Extracting the GPG message, and attempting to manually decrypt it via gpg gives me the following error:

$ gpg --decrypt enc.txt gpg: encrypted with cv25519 key, ID 0xREDACTED, created 2020-01-01

     "REDACTED"

gpg: encrypted with cv25519 key, ID 0xREDACTED, created 2020-01-01

     "REDACTED"

gpg: [don't know]: invalid packet (ctb=2d) gpg: [don't know]: invalid packet (ctb=2d)

I followed the instructions here to setup my YubiKey OPGP w/ Thunderbird: https://wiki.mozilla.org/Thunderbird:OpenPGP:Smartcards#Configure_an_email_account_to_use_an_external_GnuPG_key

Hi, I've received the email below from Microsoft today.

I have 15 email accounts linked to Thunderbird mail and use up to 5 of them daily. Sometimes 'instant' communications on one or more of my accounts can be important.

Will Thunderbird mail still function in the same way from 16th September?

I apologise if this question has been answered somewhere else. I searched but could not find it.

"The safety and security of your information is top priority for Microsoft. To help keep your account secure, Microsoft will no longer support the use of third-party email and calendar apps which ask you to sign in with only your Microsoft Account username and password. To keep you safe you will need to use a mail or calendar app which supports Microsoft’s modern authentication methods. If you do not act, your third-party email apps will no longer be able to access your Outlook.com, Hotmail or Live.com email address on September 16th.

What do you need to do?

If you are receiving this email, you are currently using an email or calendar app that uses a less secure authentication method to connect to your Outlook.com email account. You will need to upgrade your third-party mail and calendar app to a version which supports modern authentication methods.

Microsoft provides free versions of Outlook for your PC, Mac, iOS, and Android devices which can be easily downloaded and connect to your email account. Using an updated version of an Outlook application will ensure you are connecting in the most secure way.

How can you set up your Gmail, Apple Mail, or other third-party mail application?

Various non-Microsoft applications will have their own steps for connecting to your Outlook.com email account using modern authentication methods. See our help article - Modern Authentication Methods now needed to continue syncing Outlook Email in non-Microsoft email apps. However, you may need to contact the creators of those applications to provide you with instructions. In many cases, simply removing and re-adding your account with the latest version of that application will configure it to use modern authentication methods."

Now and then, when I press the Enter key, Thunderbird moves the current email message from Inbox to Trash instead of opening the message in a new tab.

I am using Version 115.11.1 (32-bit) on Windows 11.

I have accounts for my husband, sister and daughter as well as myself. Lately when I try to access my emails I keep getting messages to enter the passwords for these accounts. I have never had to do this before. I don't have passwords for them and don't even really know how to do this.

Also my emails are very slow. I was waiting for a link to a podcast and the email with the code took a little over five hours after the podcast before I received it. This has never happened before.

Help. Gail

I have various multi-members set up on TB. Most of the time, I use them just as they are, but on occasion, I would like see the members of the list displayed in the "TO" field of the email, so I can delete one or two of them from a specific email. Is there a way to do this?

In Windows Live Mail, for example, clicking on the name of the list would display the members. This doesn't work in TB. Is there a similar function?

i get a pop up when a new email come in on my main monitor. i have many. sometimes i would like to just delete it there rather than open up the inbox to delete once it arrives in my in box. a delete trash can icon would be nice to have on that pop up

I have installed Thunderbird in an attempt to escape from BT's email setup. Unfortunately, the Thunderbird I seem to have I am finding very difficult to use. Things like what to view, and how to arrange the various elements to view. Also, I seem to have a long list of messages in the inbox etc which takes a very long to time to load. I'm just wondering whether to uninstall it, and try again. Advice on setting it up would be welcomed. But please note I am not very computer-literate so, if it is a product intended for experienced users, should I try a 'Plan B'...?

my emails for my Spectrum.net account are not being received as of 6-24-2024. other email accounts still work OK. How does this get fixed?

Please assist I have 3 emails address & when I go to send a new email,it does not show up as my default Email on SMTP How Can I Change to that when I send a email,It uses my Default Email on SMTP Thank you Darryl.

When I read an email message, it changes the display from bold blue to bold black in the message list. If I then mark the message as read, the dark black changes to light black. Is there a way to do this once a message has been actually read, without having to mark it as read?

I've been happily using Thunderbird for a long time and now have version 115.12.2 (64-bit) on my MacBook Pro. It's old (10.14.6) but it's all I need. Until yesterday, TB worked fine. Suddenly, business emails stopped saving to my "Sent" Folder. I deleted a number of old emails and compacted the folder but that has not helped. I don't have the problem with other TB accounts. I checked the account settings:

               Place a copy in "Sent" Folder on (my account) – as it always was.

I also checked "Show confirmation dialog when messages are saved". Despite seeing that, the message is NOT saved.

Are my sent mails from the last 24 hours saved anywhere? If so, how can I retrieve them?. How can I make sure they are saved in my "Sent" folder? Thanks so much!

Dear Sir or Madame,

I posted this issue already earlier (https://support.mozilla.org/en-US/questions/1428881?utm_campaign=questions-reply&utm_source=notification&utm_medium=email#answer-1613810), but it still persists.

Zited from my earlier report: The usual process that happened when deleting or separating attachments from e-mails was that a copy of the email without the attachment was produced by Thunderbird and the original email was deleted.

This is not longer working. When I delete an attachment, the original email containing the attachment is not deleted. So I have two versions of the email in my postbox, one with the attachment, the other without.

Probably I'm missing a setting?

Thunderbird version 115.3.3 (32-Bit)

Still happening with 115.12.2 (32-Bit)

Sincerely yours, Markus Piotrowski

I recently got a new PC with WINDOWS 10 and loaded Thunderbird to pick up my email. However, now the mail client keeps making new profile folders, which I keep trying to delete. I am up to 6 now. THey are all in my deleted section of my Local Folders. How do I remove them for good. I thought all deleted items were supposed to disappear once you close the program, no? I never had to even deal with Profile Folders on my older PC. Thank oyu for your assistance.

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 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]  ?
