The inbox had about 18 months worth of emails. I deleted three emails that had been flagged by Thunderbird as spam. Then I went to the trash folder and permanently deleted the trash that included many other unwanted emails.

When I returned to the inbox, the full list of emails was present but after clicking on any email there was no email content shown. A new email came in and the content was shown for that email.

The sent folder still shows all the sent emails.

After looking for solutions on the web, I selected the inbox, right clicked and opened properties. I then selected "Repair Folder". Now, the only email shown in the list is the new email that came in after the issues started.

I have looked for crash reports and it says there are no crash reports.

Suggestions....? Thank you, Peter

I have a folder containing messages sent to/from a company (two different contacts). When I go to that folder I want to be able to see the individual messages. Instead, I see them by conversation (each item summarizes multiple messages). That's not how I want to see them. This changed very recently from the default of individual messages and I don't know how or why. How do I reset this please?

Thunderbird has suddenly decided that it will split the header and sender information of an email from the text message which means that if I try to print the whole message the header and sender information appears on the first page and the rest of the body of the text is on the following pages even if the message is only one page long.

The message appears correctly when I view it it's only when I go into Print Preview that the separation shows and even if I reduce the margins or remove the header it still splits the first page. The Config Editor appears to be correct in terms of the height and width of the paper being A4.

I'm not sure but I think the system was upgraded recently as this problem only started this week.

Can anyone help me?

After upgade Thunderbird to 115.0.1 version, all my outlook.com email accounts encounter an error:

Warning: Potential Security Risk Ahead Thunderbird detected a potential security threat and did not continue to account.live.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

What is the problem? Doesn't TB support outlook.com accounts anymore?

thanks.

Somehow I was running an unsupported ver 129 on a Win 10 system, not sure how. I was getting a warning message at startup. I decided to install the latest supported ver 128. I did that over the ver I was running and did not save, export or rename anything. Just one install over the other. I have lost my calendar that I spent months building. Did I lose it? Any possibility it is still around hiding somewhere? Help please, but I am prepared for the worst for being hasty in my decision. Cheers, TR

I get the message: Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox.

I got a new laptop and wanted to set up Mozilla Thunderbird for an existing Gmail account. I tried several times, all failed, with a warning "unable to connect with server imap.gmail.com, may be userid and password are wrong". But I can logon to my Gmail account (with the same userid and password) on Firefox website and on my previous computer, so the id and password are correct). And I was able to set up another Gmail account on Thunderbird in this new laptop (so the version of Mozilla is not the culprit) with the same server settings (port for incoming and outgoing mails, authentication methods SL/TLS, O Auth2 etc). Will someone please help me?

Hi,

I upgraded to Thunderbird 102.6.0 (and just now to 102.6.1) and after the upgrade, one of the email accounts I use will display the headers, but not message content. When I click on the messages in that inbox, I just get a blank page without even the "reply" or "delete" toolbar.

The inbox was working fine before the upgrade and the account that is not working has the same settings (except the first part of the email address) as an account which is working.

Any help appreciated.

Thanks!

When I Reply the cursor used to default to the text so I could just start typing my message.

Now it defaults to the address field. How can I go into the hidden settings to change it?

Hi,

My reading pane on v115 will only adjust downwards but I would like to adjust it upwards as was possible in previous versions.

Just to confirm what I mean, it will only go down, so making the reading pane smaller (or disapppear) and the thread pane larger.

I would like to make it go the opposite way, upwards to make the thread pane smaller.

Is there some code, css etc that can make it happen correctly?

I use both Thunderbird and Outlook for my cox.net email account. I can receive incoming emails using Thunderbird but cannot send emails, and I can both receive and send emails using Outlook. The server settings are identical for both Thunderbird and Outlook - imap with STARTTLS and port 993 and smtp with STARTTLS and port 587. When Thunderbird is unable to send an email, I get a balloon that indicates that the smtp server cannot recognize my email address, which is [email removed]@cox.net.

I am using Mac OS Ventura 13.6.9. I have been a Thunderbird user for many years. Since this last update, I have started having issues where not all emails are displaying. Seems like most recent emails open correctly, but when I get to emails that are a day or 2 old, I get the the following banner across the top of the screen when the email opens, but can't open the remainder of the email.

I have attached a screenshot to show what I am seeing.

I am using gmail and I can access the emails in gmail, but not in Thunderbird. What is the fix for this?

Thanks

Laura

Set up your existing email address will not work. Thunderbird stopped working no outgoing no incoming. Deleted account then downloaded new Thunderbird. Entering correct name, correct email address and password (also tried with no password) finds set up on Mozilla ISP sever. Select 'Done' brings up message "Cannot log in to server.Probably wrong configuration, username or password".

This unsolvable for me now as I have tried everything I know and suggested in Help.

Hi

I have endured weeks of Thunderbird conflicting with Hotmail.

Occassionally it works.

Today is another 'no go' day cannot trans or recieve. Hotmail online works but not Thunderbird.

What is going on at Mozilla ?

i had the latest version 115 and i decided to install the previous version coz some things didnt go my way. i opened it and its supernova - i lost everything like settings, my local folders etc. how can i go back to all my settings i had in this supernova version?

Two days ago Thunderbird no longer would send emails (been using it without problems for 7 years) I have read all the previous posts on this. Tried sending emails after disabling firewall and Malwarebytes without success. I can receive emails sent from my Spectrum email account (still works). I can send emails from my iPhone using the identical Outgoing Server Settings. The settings are in the screenshot. Also downloaded the latest version of Thunderbird today. Didn't fix it. To get around the problem right now is I am composing my emails (IMAP), saving them in my drafts and then sending them from my iPhone.Any ideas? Thank you!
