I received a new modem from my internet provider Start.ca. Since then my emails have stopped coming in. All the lights on the modem are solid green except the LINK light which is flashing rapidly green. I have 2 questions. #1 how might i resolve this. #2 I know there are emails trapped in the queue at this point. Is there a way I can get access to those emails now within Thunderbird? I was told I could by logging in to my email portal but I do not know how to do that. Any assistance would be greatly appreciated.

Can't seem to get thunderbird to connect to my xfinity (comcast.net) email... tried full reinstalls, changing the password, and all the steps in this: https://support.mozilla.org/en-US/questions/1437228

As well as trying "normal password" instead of OAuth2. The OAuth2 option does not seem to generate a pop-up to authorize that way. Using other 3rd party and logging in via browser also work.

Does thunderbird need to update something to fix the issue? Its been only a few weeks now for me that this was an issue.

Hi, hope to get some support here for my problem. I did recently the upgrade to Ubuntu 24.04 and since then Thunderbird is a Snap package. Thunderbird works fine, as before, the only thing is that after a reboot of the system the path to the local folders storage is set to a default path. I can adjust this to the right path via account settings (my local folders are on a Synology NAS), en then restart TB but it is annoying having to do that every time. Does anyone know of a more permanent solution? Any help much appreciated!

Entrei nesse universo com curiosidade e logo percebi o enorme potencial de transformação que ele oferece, tanto em termos financeiros quanto tecnológicos. Pude explorar como a blockchain revoluciona a forma de realizar transações, trazendo mais transparência, descentralização e inovação. Cada etapa foi um aprendizado fascinante, desde acompanhar as tendências do mercado até entender a importância da segurança digital. Foi uma jornada cheia de descobertas, crescimento e, sem dúvida, uma experiência inesquecível."

Dear all, I wonder if there is a way to enable marking a message as read directly in the notification when it arrives. Sometimes I receive messages that just by reading the subject I already know I don't need to read it. Therefore, I would like to be able to mark this type of messages as read from the notification, rather than having to open Thunderbird and click it. Is this possible?

 best,
Vic

Hi, For the past few days, after starting Thunderbird, I've been regularly receiving a notification (bottom right of the screen) about an incoming "private" email - see screenshot. But such an email cannot be found anywhere. What is this or what can it be??? Greetings Lutz

Impossible sending e-mails regularly from a few days ago.

A message "Too many sending failures" appears though failures are a very few ones and this block increases every day.

How can be it solved?

On the "Organize your messages with filters" page, it describes how to create a filter, but doesn't describe what can be entered into the "value" field. Simple text strings are shown. Are the entries restricted to text strings, or are there special characters? Can hexadecimal values be entered?

The reason I'm asking is that I am receiving many emails where the "From:" address ends with ".za.-com". I haven't been able to get a filter to recognize that. Is the "-" (hyphen) a special or prohibited character? Is there a means of recognizing that string at the end of an email address?

Thanx!

Wife and I have two separate desktops on a MS Win 11 PC (desktop). I have T-Bird ver 136.0 (64 bit) running on my side working perfectly. We just tried installing her old T-Bird account on her side, and after a while, we got it installed and are able to RECEIVE mail--also on ver 136.0 (64 bit), but can't SEND. However, there are two problems:

1. Our two versions look quite different on our individual sides of the computer. Why?
2. As best we can determine, all our settings are the same; however, she can only receive--can't send emails. She gets an instant constant error msg: Unable to send, outgoing mail server xxxxxxxxx has timed out. It's the same server I'm using! We have triple-checked all settings between our two accounts, but still no luck. We have checked with our email service provider (WOW!/Knology), and they have shown us how to set up their internet email account to use at a hotel when traveling, but not at our home PC. Any help here would be GREATLY appreciated!

Many thanks, Jay

I think my email has crashed. I can see emails through yesterday but can not receive anything from today. All attempts that I am capable have been tried and I can not understand all of the instructions for "crash" help.

A window keeps popping up and asking for the password of one of my accounts i put the password in and it says that it is not correct, i then went into settings and looked at the passwords for each account and that account it not there. Looks like that email has disappeared

In the past week or so I have noticed that some emails disappear from one inbox on my Windows 10 PC. I have three Thunderbird accounts (call them A, B, and C), and the emails only disappear from box A. It seems completely random, and furthermore they only disappear on my own PC. My husband has an identical set-up on his Windows 10 PC, which also includes the boxes A, B, and C, and the messages do NOT disappear there. I can also see them on my iPhone and two iPads, and they do not disappear from those. I have tried forwarding them to myself from my phone, and while most of them did show up in the A inbox on my PC, I have noticed that some of them have now disappeared again.

This is incredibly frustrating, because I do most of my work at my PC. I thought I needed an update, but TB says I am up to date (128.8.0esr (32-bit)). It can't be anything to do with the server, because it is so specific: one inbox on one PC only. There doesn't seem to be any special pattern--some have attachments, some don't.

Many thanks for any suggestions!

I now have four calendars running, using different colours. Is it possible to get past event colours to dim automatically, please? (The Google calendar does this and it looks good). Would be grateful for suggestions.

I am experiencing an issue with sending emails in Thunderbird after updating to version 136. The "Send" button does not respond when I try to send a new email. Incoming emails are received without any problems, but when I compose a new message and click "Send," nothing happens. As a result, I am unable to send any emails.

Could you please advise on how to resolve this issue?

Other people receive emails with attachments in Cyrillic from me in encoded form. It is recommended to change the encoding on the Internet, but there is no such menu in the current version of the program. How do I open the encoding menu? I really need this because I cause a lot of inconvenience to others.

I've been using Thunderbird for quite a while without any major issues, but yesterday, I ran into a problem that I cannot figure out.

I have a bunch of templates that I use regularly to create emails. The usual procedure is to click on a template email in the "Templates" folder, make the edits I need to the body content, modify the recipient information if necessary, hit send, and away goes a new message.

Yesterday, I click on a message in the Template folder, and nothing happens. The template message does not open up. If I right click and say "Create a new message from template" or whatever the exact prompt is, nothing happens. No new message is created.

I have tried creating a new message and saving it as a template, click on the new "template", and still nothing happens.

I have tried repairing the folder, using properties, but this is only offered if I click on the "Local" subfolder version, not on the "Unified" parent folder. No change.

I tried backing up the profile for security, deleting the "Template" message and index files, to try and see if recreating a new folder will work ... again, same results. Click on a template message and nothing happens. Right-click and select "create new message..." and nothing happens.

I have NOT tried creating a whole new profile yet since there are multiple email accounts, various custom search aggregations, and other customizations that have all been working just splendidly that I don't want to have to recreate all over if I can avoid it.

Running TBird 136.0 (64-bit) on Windows 11 which TBird reports is the latest / up-to-date version.

So far as I can tell, ALL of the other folders, sub-folders, local and IMAP, work as expected. I don't have this "message won't open" problem with any of them. This is affecting only templates and it's left me scratching my head.

Thank you in advance for your help, suggestions, and hopefully, solutions!

Dear support team, I've the following issue with calendars in Thunderbird. Was on latest ESR version, an upgrade to latest version 136.0.1 (64 bit) didn't fix it: When I started Thunderbird, suddenly most of my calendars where no longer visible. I figured out by trying to add a new calendar it only (re-)appeared when "offline mode" (caching) was disabled. After changing the setting calendar.registry.[id].cache.enabled to "false" the calendars showed up again.

Could it be some kind of bug or could the calendar storage be corrupt? How can I fix it?

Many thanks in advance for an answer!

Kind regards, H. Bruecher

I have set up Thunderbird and keep getting this error for email for my client.
