"Your Thunderbird profile cannot be loaded. It may be missing or inaccessible" keeps appearing mid-screen. version 147.0.1 re-installed several times (Win-10). Transfers of profile attempted from operating PC (Win-10) Cannot locate profile even in a "fresh Install" although the shortcut appears on screen and other associated files seem to be installed. Helps have been downloaded and tried. Same issue. I've received help suggestions from Lin and sfhowes both on 2-6-26.. Thanks for your help.

I used Thunderbird for many years, but starting in August 2025 it stopped working. It was getting an error in the smtp server, and I was unable to resolve that issue. When I try to login to Thunderbird now, it tries to send a message to pwrichcreek@twc.com, but that no longer exists. Thanks for your help.

We have our accounts on one computer and one dedicated email (using Thunderbird) which sends our invoices to our customers in PDF format as an attachment to an email. This stopped working a few days ago. The tech department of our accounts package supplied by Benchmak/Snip has looked at our system and the only thing they can suggest is that the emails are being blocked because may be Thunderbird thinks they are SPAM. We have been using this system for a couple of years now and has been fine. We can send and receive emails to/from this account, it's only the PDF attachments of invoices which isn't working. Can any one help please, thank you.

I am setting up Thunderbird on a Win10 machine, and am having a lot of trouble adding accounts that I did not have on the two Win11 machines I have set the same accounts up on.

When adding my 2 GMail accounts, after clicking "Allow" on the OAuth popup the button would go grey the window would stay open and not close, and the account would not be added.

Changing the general.useragent.compatMode.firefox option to TRUE allowed me to progress and finally add those accounts.

I am now having the same trouble with my @hotmail.com account. When I add the account, the dark blue OAuth window pops up, but is completely empty, and there is nothing more I can do.

Things I have tried

• Reverting the above config change
• Checking that cookies and JavaScript are enabled
• Checking there is no saved password
• Used both the Account Hub and the default dialog, with the same effect.

Thanks in advance!

When my message filter uses the "Reply with Template" action, the reply e-mail is always PGP encrypted, even when I do not have any public key for the recipient e-mail address. As a result, the reply e-mail is always corrupted.

I am using Thunderbird 140.7.1esr on Windows 10.

I have attached a screenshot of what the reply e-mail always looks like.

In the Template that I am using, the "encrypt" button is not selected, and in the OpenPGP menu of the Template, the "Encrypt" menu item does not have a checkmark next to it.

Does anyone know how I can get Thunderbird to send reply e-mails without using encryption?

I really have given up on Thunderbird, even though I have been a loyal supporter of the product for many years.

For the last year I have had to bypass Thunderbird and read my emails either on my mobile or directly from the BT server, which is how I am writing this mail.

My problem is , although I can view my mail perfectly on my mobile and of course on the BT server, Thunderbird seems totally incapable of transferring the mail to the Thunderbird inbox.

Thunderbird is not able to show the text and any images, all I get is a mail with a number of boxes, no pictures or anything of any use.

Is this since a Thunderbird 'update' or what, I don't know.

A little while ago I posted this problem and only got one reply from an 'expert'/community which failed to solve problem in any way.

I have also lost many of my earlier mail

Is it time to abandon Thunderbird and change to the dreaded Microsoft email package?

Yours faithfully in great expectations that someone somewhere most know how to fix Thunderbird

In Advanced Preferences there are multiple mail servers listed such as "mail.server.server18.hostname". There are at least 18. I have not been able to download messages for 3 weeks and can't figure out why. I have used Thunderbird for many years. Sending email works. Email provider is Shaw/Rogers

Why did retrieving messages suddenly stop. It was working yesterday and I made no changes to anything. I can send successfully. I am using Shaw/Rogers Pop server.

Why does "test connection to server" fail?

On my PC Thunderbirds sending/receiving mail says the mail server refused my connection. My laptop works fine. I have duplicated my laptops in/out specifications onto the PC but still nothing works. Spectrum says everything on their end is fine but can't vouch for roadrunner who is the rr in my mail address of ca.rr.com. All this started about 4 days ago. Any ideas on what to try next? Thanks.

Is there a document somewhere that gives the meanings/explanations of all the choices when selecting settings for a Thunderbird account ? When I go through the settings there are many choices that I do not know what they mean, and finding each separately could take hours ...

I am having a major issue with Thunderbird not saving Outgoing emails in Send Folder with IMAP setting.

Having three mailboxes two are set to IMAP and the third set to POP3. The IMAP outgoing mail creates an alert that mail was sent but copy not placed in your Sent folder due to network of file access errors.

Outgoing mail in POP3 save immediately to the Sent folder.

I am using the latest Thunderbird update:

• Server Type: IMAP Mail Server
• Server Name: IMAP.kinect.co.nz
• Connect Security: SSL/TLS
• Authentication Method: Normal Password

Outgoing Server [SMTP] Settings:

• Description - User name
• Server Name: smtp.kinect.co.nz
• Port: 465
• Connection security: SSL/TLS
• Authentication method: No authentication

Note: Authentication was changed form Normal Password in order to gain some traction on the issue during trouble, cause and correction actions.

Addendum: The PC was fitted to Starlink https://en.wikipedia.org/wiki/Starlink in preparation for use as sole source for internet connection. That was abandoned due to email issues.

Hi, Lately I've been experiencing problems with Thunderbird (115.5.1 - 64bit). I have to shut down some apps and sometimes restart the computer in order to be able to get and send messages on my google account. Also, I can't get to the yahoo account and I get a new window to enter my username and password for yahoo but when I enter them, I get a "Something went wrong" notification and suggestion to try from a diffrent device. Everything was allways fine. What went wrong lately?

Thanks a lot, Mickey
