Hi. I have an email purporting to be from Microsoft telling me that I will have access problems with Thunderbird from September onwards. Something to do with authentification. Assuming it is genuine (is it?) I have no idea what to do. It gives 'instructions' which are incomprehensible to me. I dont even know why this link is to Mozilla rather than thunderbird. I don't want to loose Thunderbird's calendar or stored files let alone the ease of access I currently enjoy. I need someone kind and patient to tell this novice how to move forward in a pedantic, non-terminology way who is happy to assume I know nothing! Please help! Brian

Had a Windows update, and it apparently screwed up Thunderbird. Can't block delete messages, and the write message screen size changed - it's now all the way across the screen. That's just for openers - can't imagine what else might be screwed up.

Tried "troubleshooting" and it didn't work, and have no idea how, or if, the changes from the Windows update can be reversed.

Thanks very much for your help. I've been using Thunderbird for many years, but the mail has become almost unusable - if mail can't be fixed, what do you recommend to replace Thunderbird?

'bold text'bold textOn 6/24, Juno Security <security@support.juno.com> sent me an email that Thunderbird downloaded that my account had been compromised, & I needed to reset my password. I chanced my password in Juno & put that same password into Thunderbird [I think] Since then I have needed to use that new password to open the Thunderbird program, but Thunderbird won't download email from my Juno popmail to Thunderbird. Thanks for your help.

Unable to open the folder Inbox on best.one@comcast.net because it is in use by some other operation. Please wait for that operation to finish and then select the folder again.

To address the 'write auth' error, I followed the instructions given to re-create the email 'from existing' and set the config as POP3. When I clicked Done I got an "error Creating Account" stating that "incoming server already exists." what do I need to do next to get past this?? Please advise. thx

This should be a simple issue but I've been struggling for ages. I changed email host and have a backup of my profile taken before the changeover, which caused my (IMAP) emails to disappear. But I have that backup profile. That one I've called 'Profiles - old' and placed in in the same folder (>>>Roaming>Thunderbird ) as the new one, called simply 'Profiles'. Only Profiles is read but I can use oneor the other by swapping the names around. There are emails in that Old profile that I want to copy to the new one without losing what's already there. As I say, this ought to be a simple matter, and it probably is, but so far I've waded through reams of online instructions that I've found to be either inapplicable or more less unfathomably techie and not come up with a solution. Help would be much appreciated!

I use Thunderbird for email in and out but had an email from Microsoft stating that some changes are being done about access to Hotmail after September 16th. part is below:- Update your sign-in technology before September 16th, 2024 to maintain email access.

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.

Sometimes when I consign an email to the trash and then need to re-read it later, it's turned into gibberish. A tiny fraction of a recent is below. I've used the "repair text encoding" feature, without any result. If I scroll further down in the gibberish, there are links that weren't in the original email and would have had to be sucked in from other emails in trash, which I just don't get. I can go back to the email on my phone, but on my desktop, they are hopelessly jumbled. What causes this and how can I stop it? Thanks!

Hi

I've been using Thunderbird for years with no issues. It's set up using IMAP and downloads emails from the web from my ISP. I have several different email account with my ISP. They are all set up to download to Thunderbird. All but one is working fine.

My primary email, however, is only downloading intermittently. It downloads all my emails on start up, then doesn't download any more unless I close Thunderbird and re-open. This is a new issue. Nothing has changed in my set up which is configured identically for all my email address (and the others are working fine).

I cam getting constant and continuous multiple security exceptions for p53-caldav.icloud.com saying it's the wrong site. I have made not changes to the thunderbird setup except for normal updates. i've confirmed these multiple times but they still keep coming. Any help would be great

"Unable to open the folder Inbox on best.one@comcast.net because it is in use by some other operation. Please wait for that operation to finish and then select the folder again." ????

I have 3 gmail accounts on thunderbird. one stopped working a few months ago. attempts to re-add have failed even tho I set the same server settings as on the other two accounts.

my hotmail account asks for a new password every once in a while. if I ignore and restart thunderbird this goes away for a while. tried to update with the new Oauth2 and now that account isn't working either. can't send mail. tried to delete and re-add, no good. have shut down and started again - no change

Thunderbird v115.12.2 (64 bit) Build 20240621154414 Runing on Windows 10.

We've noticed an odd behaviour with the replied icon to the left of the subject column in the main Inbox display. Sometimes, the icon is present for messages we've replied to. Sometimes it appears and then disappears after another Sync and sometimes, doesn't appear at all for messages we know we've responded to.

Introducing the Status column into the main display does not show different results to the icon. If the flag is missing to the left of the subject column, the status only lists the message as read.

Firstly, has anyone else experienced this on and off behaviour and secondly, what specific feature needs to be present on the server to fully support the replied flag? I'm hoping it's a server issue that we can raise with our provider.

Many thanks.

Today I changed my Google password, and now I can't login via Thunderbird to get email.

On startup, I am prompted with the Google login screen, which asks for my email or phone. I click Next, and get the message

   400. That’s an error.

   The server cannot process the request because it is malformed. It should not be retried. That’s all we know.

I'm using Thunderbird 115.10.1 (64-bit) on MacOS Sonoma 14.5.

My thunderbird email account was on my old laptop and now I'm trying to get into it on a new laptop and it is asking for a password that I've forgotten and doesn't give me the option to put in a new one. What can I do to get my old email account working on my new laptop?

Husband's email account says he can't send emails; this happened on my account a few weeks ago but I can't remember how to fix it. Can someone look at these screen shots and tell me what we need to fix? Thank you so much for your help! (NOTE: Spectrum is the provider.)

I am able to check both hotmail and gmail accounts with Thunderbird. I deleted the accounts. When I tried to readd them it said Thunderbird failed to find the settings for your account. Anyone else experiencing this? What should I do.

Hi

I am having trouble finding emails with malicious attachments. I'm using one of ESET's security products which, after scans, find malicious content in the INBOX file, located locally on the device under the path %APPDATA%%RoamingThunderbirdProfiles(_Name_Of_the_profile)_Imapmail(_Name_of_mail)_INBOX(mail123). Unfortunately, the security product is unable to get rid of the dangerous file, but only gives information that something bad is in the email. When trying to find a specific email, I unfortunately run into a lot of problems. 1. the name of the email - in this case "mail123" does not exist in the thunderbird application itself. If I understand correctly, thunderbird itself chooses names for individual mails and then packs them in the INBOX file. 2. it is possible to correlate the email name from the INBOX file to the actual name(subject) of the email using other software such as MailStoreHome by importing the entire email profile (_Name_of_the_profile). 3. once the email is already correlated and found in MailStoreHome, I should be able to find the same email in Thunderbird (as I have imported the INBOX file, which is located locally, and which Thunderbird itself reads). Well, unfortunately no. Such an email in the Thunderbird mailbox (I already know the subject, content, date, etc.) does not exist.

And here comes my question. Is it possible to open the INBOX file itself and then find the unfortunate email and delete it?
