I've been using Thunderbird and its Calendar for MANY years very happily :-) My old main computer is a w7 Lap and the Thunderbird Calendar in that version has the option to set up a Reminder Notification via Email. And it still works with no problem! I just was given a used Laptop computer that I did a clean install of w11 on, and installed Thunderbird and setup the Thunderbird Calendar to my Google Calendar with NO problems! EXCEPT: I just created a New Event and a Reminder for it, and to my chagrin, there is NO option to be notified by Email anymore !!! grrrrrr  :-( Please, I beg the developers to reinstate that option ! I use that for every event that I create! eg I take MEDS and when I get the email reminder, I can delete the Email reminder to show myself that I've taken that med at that time !!!! Please advise ! THANK YOU

Since installing Thunderbird contacts are disappearing from my iphone. They've also been deleted from gmail and icloud. How do I stop thunderbird from deleting my contacts?

I use Thunderbird Mail Client to access multiple Synology MailPlus accounts and accounts from Gmail and other services

Everytime ! Weekly! After Microsoft pushes another update I have to reconfigure Thunderbird to access Synology MailPlus accounts to receive mail. Mail on GMAIL, SPECTRUM and other mail services are not affected.

Microsoft is breaking something preventing only Thunderbird from retrieving mail from MailPlus Server.

I have to remove then add the accounts back in, Retrieving saved Profiles does not work to fix the problem.

Hello.

I have just downloaded Thunderbird for the purpose of importing .mbox file from Google Takeout. It worked with the ImportExportTools NG add-on.

Since I liked the app, I decided to add my other e-mail accounts. The initial account I added looks to be working as intended.

However, on all of the other accounts, which are outlook.com and hotmail.com accounts, "No messages found" is said on the inbox and they are all essentially dead. The login process worked fine and so on, but then nothing happens. I've tried to look at the various settings, but I can't figure it out. It's all the same as the main account, to my eye.

I am on Mac Sequoia 15.3.2.

Thanks for any feedback.

Good afternoon. Can I disable this default option “Keep messages for this account on this computer”? I installed thunderbird on a terminal server. I configured autoconfig. I want the user to enter only email and password, and mailbox is configured but only email headers are downloaded. I found on github policy-templates, but it doesn't have this option.

I am running Thunderbird on an older HP Probook with Debian 11 installed. On April 9 or 10 the machine did an OS performance and security update and after that Thunderbird will not open. I have uninstalled and reinstalled the program to no avail. It will not open from Gnome or Terminal. I am not that technical but I know there is a way to fix this. Also I need to make sure my emails are not lost. Thank you, Jimmy Rone

I successfully subscribed to an online .ics file but I found the resulting calendar entries inadequate and I want to unsubscribe but I can't figure out how to do that. I've tried searching for instructions but haven't found any.

I run Thunderbird 128.9.1esr (64-bit) on Linux Mint with the email and calendar service from Mailbox.org

I receive an invite from google mail user. See screenshot.

Thunderbird does not recognize that this is an invite. This is the problem

Hi, I have a strange experience with thunderbird's calendar: an hour or two after i created a new appointment in my calendar, i cannot change this appointment anymore. When i do so, this appointment is not saved anymore when i click on "save & close". When i alter and save this appointment within the hour it works normally and the item is saved as expected. I searched the settings, but nothing could be found concerning this issue. My OS: Ubuntu 24.04.2 LTS. Thank you very much for your efforts. Wyl. Holland.

I am an experienced TB user, but at the moment at a total loss for a solution to my problem.

I use Windows 11 Pro. When trying to click on image attachments for PNG and JPG/JPEG pictures, the behaviour is different: PNG images are displayed just fine in the Windows photo viewer, JPEG images are not. If I open the same images via double-click from the local disk, both open just fine in the same viewer. I have checked the file type settings already and even changed them to always ask me for JPEG images. I get asked just fine and see that TB wants to open the Windows photo viewer for both files types, but while it works for PNG, it does not for JPEG. There is no error message, just nothing happens, at least nothing visible to me.

When trying the same from a new user profile, it works as expected. I tried TB safe mode, deactivating all add-ons, but it still does not work in my main user profile.

I would be glad to receive hints for how to solve or at least debug this. Thanks in advance.

Bonjour Les pièces jointes est très longues à ouvrir 40 secondes voir plus, y a t'il un moyen plus rapide ou une manipe à faire pour régler ce problème Merci pour votre réponse

No matter what settings are used Thunderbird says the unable to login at server. I have tried multiple variations to the configuration with the same results. I have an existing gmai laccount that works. I can access my email.com thrrough the browser fine.

A few months ago I posted a question "I'm no longer offered the option to use FILELINK". There was a solution offered by user Yu5tiqX9og. That post has apparently been archived, so I'm unable to see whether Yu5tiqX9og's solution/reply was ever posted. I managed to keep a copy of his solution, which he must have sent to me privately.

  I italic text do remember that it did fix the problem I was having.
  Here is the reply. 

italic textThe following steps might be helpful: "Settings" > "Composition" > "Attachments" section > tick "Offer to share for files larger than __ MB. (Please see the attached image.)"

I don't have the exact image from the original post, but I've recreated what I believe it probably was. Please see attachment. I hope this helps, SweetTasha

I just upgraded my computer with a new motherboard, CPU memory, and Windows 11. In the process of reloading all of my programs, I found I was unable to create my comcast.net account in Thunderbird. After trying several times in several days, I wondered if this was a Thunderbird problem. So, I tried it with Outlook. Same problem - it wouldn't connect to the server. Then yesterday I noticed I wasn't getting email on my phone. After doing some research, I found that there's a large number of people that can no longer access Comcast.net email, especially if you're trying to set up your account again.

Now here's where I am running into a dilemma. I saved my old Thunderbird profile before I upgraded. Since it was way over 2GB, I copied it to my backup drive. Now, though, since I have to switch to a different email provider, what will happen if I just replace this new profile with my old, saved one. Will it still work? I have a ton of email that I need to save and be able to access through Thunderbird again. If not, what files in my old profile will I have to move over so that I still have access to my address list, calendar, and email?

Can you help me out? I still plan on keeping Thunderbird as my email client.

Thank You!!!!!

I have 3 Thunderbird e-mail addresses. The primary one is franks@rochester.rr.com, and the secondary ones are dda1@rochester.rr.com and muse@rochester.rr.com. The franks@... and muse@... ones are fine. However, I cannot delete anything (messages or folders) in the dda1@... address. The only way I can delete a message in dda!@... is to right click, choose Move to, and move it to franks@rochester.rr.com/Trash, where I can delete it. I cannot do this with folders. Related (I suspect) is that I have 2 Drafts folders within Trash, and I cannot delete them by any means, including Empty Trash. I can right click, Move to the franks@... Trash folder and delete it there, but it still remains in the dda1@... Trash folder. What is wrong with dda1@rochester.rr.com? p.s.: I've contacted my e-mail provider, and we have determined that everything works well there. The problem is with Thunderbird.

Hi,

I have what appears to be a common issue, but the common solutions I found don't seem to help.

I migrated to a new Mac[1], and my Thunderbird[2] on Mac times out while sending messages through the SMTP outlook server. So I am unable to send emails from account. By migrating, I mean I copied over my entire ~/Library/Thunderbird and used that. It actually did work for a few days. But then it started failing.

There are some common suggestions on the internet for how to fix this, and I have tried them all:

• make sure correct settings are used. I am using Outgoing SMTP Server: smtp.office365.com, port: 587, security: STARTTLS, authentication: OAuth2.
• make sure Firewall is disabled
• restart Thunderbird
• restart Mac
• delete Thunderbird folder in Library, and just start over with a new profile.
• change Thunderbird time out setting

The error I get, after about 15 seconds is: "Send Message Error. Sending of the message failed. The message could not be sent because the connection to the Outgoing server (SMTP) smtp.office365.com timed out. Try again."

I have no problem receiving email, but am unable to send.

I tried gomtp to look at what was happening, but I wasn't sure how to configure the ssl, tls, auth settings and how to specify where to find the password.
