I received an email from Thunderbird (my email provider) wanting me to join the Early Bird Beta but their link to pay with PayPal didn't work so they requested I add a new credit card. I use PayPal often so I know my card on file with PayPal is OK. Seemed odd to me for their request. I could forward their email to me if needed. Looks like they are using Paddle.com Market Limited.

Was unable to edit appointments attempts placed a previously unknown dialog box. Search for info found one person advised Select Calendar (tab), edit, calendar properties and uncheck the read only box.

In my case the box was already unchecked, checked it, tried it, same result. Unchecked it, tried it same result (not able to edit).

Next I thought maybe some data location is not being changed. So I closed all files, shut down (not a restart) my machine, and restarted it. Opened Thunderbird and tried to change an appointment, did not work. Went to Calendar (tab), edit, calendar properties and found the read only box checked. Unchecked and all seems back to normal operations now.

When i send an email , it goes to the destination email address all right, but the problem is that it creates two identical entries in my local "sent" folder. As if i had sent the email msg two times. This happens only with my hotmail.com account. All of my other accounts (gmail, yahoo etc) dont have this problem. I am using a windows 11 laptop, and both my windows and Tunderbird are fully updated.

Since the Thunderbird update of 30 Sept the ability to attached files to my emails has 'vanished'. I press the attach 'button' but there is no response. Never had this as a problem before. I am running Windows 11 home version. Help!

I keep getting the following (see attached image) when I try to open my Thunderbird. I tried to unsuccessfully open safe mode because it still asks for a password from my very old BlueHost account. I previously worked with AI on this and deleted all BlueHost lines I could find in my account. View the image I have included and see all the messages that include BlueHost. They must be hiding somewhere in Thunderbird. I am not sure what version I have because I cannot open it. Please help! I be happy to send you my phone number is needed.

Hello,

I'm moving to Graph from EWS and have followed the instructions at: https://support.mozilla.org/en-US/kb/microsoft-ews-graph-migration

I get through to screen that offers Graph API as an option, alongside IMAP, POP3 etc, and click on Graph API which directs me to my browser to log in to my email service (via GoDaddy). I log in successfully which takes me to the Thunderbird 'You're All Set' screen saying the account has been securely connected to Thunderbird and therefore ok to close that screen.

Back on Thunderbird it then progresses but returns with "Authentication Error - unable to log in at server. Probably wrong configuration, username or password".

The username and password are correct, and there aren't any other options available when editing/manually configuring the connection...so at a dead end, alas.

Any pointers much appreciated!

When editing a contact in Address Book, after selecting a time zone from the drop down menu and saving the contact, only the first 7 characters of the time zone string are displayed in the contact view. When reopening the contact for editing, the time zone field is shown as empty again.

I swap computers about 3 times in year, and not all of mine emails seen to have transfer. I was wondering if there is any way I could potentially recuperate those emails.

I use T-bird for my email accounts and have for decades. This includes accessing an enterprize version (work) as well as basic personal gmails and even another non-google web based email account. I'm an ardent fan. I recently had to reinstall on wiped/cleaned laptop (workplace IT situation). Since then, the 2-factor authorizations have been creating problems. Including: a pop-up whenever I open T-Bird on my laptop, requiring me to sign-in to a ghost Google account. This would be less of a problem if either:

1] the account in the pop-up window hadn't been disabled over a year ago, OR
2] I could change the account in the pop-up to one I still have (can't) 

3] PS: yes, my settings for my other google accounts are at SSL/TLS & OAuth2 (except for the one that requires 4]PPS: No, the ghost account is not listed as one of my 6 accounts in T-Bird, and it was deleted long before I had to re-install T-Bird on the newly wiped hard drive... 5] I cannot log into the ghost account and disable the 'sign-in with google' option, because it's disabled/shuttered/NoLongerLive. 6] Yes, I've cleared the cache. Multiple times. 7] Yes, I've updated to the most recent T-Bird (158.0)

The popup only happens with T-bird, and only on one laptop (ot others I use, which also have T-Bird). I really don't think this is a problem at the google end, much as I'd be happy to blame them.

• MY QUESTION*: Where would T-bird, supposedly a fresh install on a recently wiped drive, be pulling the ghost of a previous account as part of the 2-factor authentifications, from? Would it be in the Config Editor? Bottom line: How can I make it stop?

Using Thunderbird 115.18.0esr Supernova 64-bit on Mac laptop OS 10.13.6. Worked fine for years, with ongoing Thunderbird updates, even though Mac OS is 32-bit. Suddenly, after 10/6/26 can't retrieve emails although I can see them on the ATT Yahoo server website. Can still send emails with Thunderbird. Inbound server settings are: POP server inbound.att.net, Port 995, SSL/TLS, Normal Password (I long ago created a Secure Mail Key, and even tried creating a new one). But inbound server name doesn't show in Saved Passwords (only outbound server with Secure Mail Key as password)? I have tried everything suggested, repaired my inbox folder, updated Thunderbird files, etc. in Profile as recommended. But still no prompt for password when attempting to get messages. Just shows "Done" at bottom left with no new messages received. But new messages are seen on server website. So it appears that Thunderbird isn't able to connect to the ATT Yahoo server to get emails. Why? And what else can I do? I love Thunderbird and want to continue using it.

I have been getting the following error message each time I log into my email today: " The STAT command did not succeed. Error getting message number and sizes. Mail server pop.bluedomino.com responded: [SYS/TEMP] Internal error occurred. Refer to server log for more information. [2026-10-14 12:31:46]" I get a message for each of my email accounts. My spouse also gets the message on hers. The server we use has just been transfered from Blue Domino to Network Solutions.

A week ago my sent emails were being rejected and the error message included something about bluehost (I called them and it was fixed within the day). Now it's happening again and my error message says:

host eig-east.smtp.a.cloudfilter.net [3.228.35.199]

   SMTP error from remote mail server after end of data:
   550 Connection Rejected - see http://www.spamhaus.org/query/ip/162.241.218.139 AUP#BL

Recently I updated Thunderbird. When it rebooted, all my emails in the INBOX and ARCHIVED folders were gone. I have tried the usual solutions, including REPAIR FOLDER buttons. Those archived messages were important. Any chance of finding them?

I receive emails yo simon@padworks.plus.com, but cannot send them, with a message saying ...

Sending of the message failed. An error occurred while sending mail. The mail server responded: Unknown sender. Please verify that your email address is correct in your account settings and try again.

please also reply to simondowthwaite246@gmail.com

Thunderbird flatpak -1.0 I recently lost the ability to attach files of any kind to messages. when I click the button to attach, no option to choose messages from files are available. I cannot go to the file and share with Thunderbird. I cannot copy a file and attach it. I have tried restarting Thunderbird, and my system (Po_OS Linux) with no result. thanks for the assistance!

At Thunderbird > Settings > Privacy & Security > under Passwords > "View Saved Password", the dialog box pops up correctly. But the size of the box is so small the columns can't display the complete info i.e. username, password, or date. When I hover on the column divider I get the left/right sizing arrow but nothing happens when I click & drag the arrow. I am on Thunderbird 159. Thanks.
