Whenever I get an email that says they are including an attachment, the attachment is never there. What is going on and how to I get email attachments. Any help is appreciated.

Thank you

Hello everyone,

like the title says, I want to set appointments in the calendar to private. I have shared calendars. Therefore, I need to be able to set some invitations to private.

In Outlook, it's no problem to set an accepted appointment to private, but in Thunderbird, this option only seems to be available for appointments I have created myself.

I'm using the latest version (145) and I've setup my office 365 email account. I'm trying to setup my calendar account as well but when I enter location, username and password it says that my credentials were not accepted.

I assume this means that TB is using legacy un/pw authentication which is no longer supported instead of OATH2. There is, however, no option to select OATH2 in the calendar setup process (like there is for email).

Are office 365 calendars supported by TB 145?

Hello Everyone,

In Thunderbird, I'm receiving a notification that I had a new email, but then it disappeared and didn't appear in my inbox. It reappears after about an hour. (but i'm not sure if i'm receiving all the email email or not) This happened after updating to Windows 11.

There is enough space. I uninstalled and reinstalled. It's up to date. The emails are not in any other folders. The same problem occurs on the website. Everything is working OK with my company email address; the problem only occurs with my personal email address, and I use both on the same laptop. This issue happens with all received emails from all email providers, such as Gmail and Hotmail..etc. Can anyone help me with this issue?

Hi I was using TB 142 without problems. When upgrading to 143 ou 144.B4 I have problems sending mails to all users after some times. Usually the first mails are sent immediatly but after around 10 mails, I have very slow response (varies from 5 sec to more than 1 minute and sometimes timeout). Usually quitting TB solves the problem but this is very annoying. I went back to 140LTS and sems to have no longer this problem. This was tested on many diffrent networks. I am running under Fedora release 42

Thanks

Optus (Australia) emails can't be sent or received by Thunderbird on my PC via my Optus wifi internet connection. I can use emails on my phone via mobile data with wifi turned off (different email client on the phone, though). Optus checked all the settings on my PC with me and they are all correct. They insist that it is a Thunderbird issue (doubtful, IMHO) and that I contact you. Is there an issue with Thunderbird connecting with Optus email? If so. is there any resolution to the issue? If not, can you confirm no problem from your end so I can get back to them (again!)

I recently upgraded my older PC from Windows 7 to Windows 10. Thunderbird worked fine for a few days following the upgrade, but when I went into it today, all the local folders were gone. 4GB worth of e-mails. Good thing I backed up four days ago, so I haven't lost much.

I have searched through the help given earlier for a similar problem, but can't seem to still get Thunderbird to work properly. Furthermore, Thunderbird won't import the backed-up data. I also can't get the menu bar to show along the top. What all am I doing wrong?

Been getting a bunch of this, usually in my TB TRASH folder, I think from the Outlook online server.

The server couldn't retrieve the following message:

Subject: "Stephen Tanner"

From: "Not available" ("Not available")

Sent date: 10/31/2024 2:25:02 PM

The message hasn't been deleted. You might be able to view it using either Outlook or Outlook Web App. You can also contact the sender to find out what the message says.

What does this mean? Outlook or Thunderbird? What do I need to do?

I am having severe problems downloading and syncing my emails with TB 142.0. I opened TB this morning, for example, and it took more than 20 minutes for it to download my emails. When I go to the next email, it takes a couple of minutes to load it. I have had some issues with slow syncing before, but this is very bad. I note that the emails work fine on my phone. Also, this happens on my main Gmail hosted account, but also on my other Siteground hosted accounts. TB seems to be lost in some kind of loop when syncing.

We have about 40 people still using Thunderbird with Exchange Online. One person is seeing many empty grayed-out folders and subfolders in Thunderbird. If you try to delete them, they come back. If you try to unsubscribe the folder, it comes back. They persist from client to client, computer to computer. Logging directly into Exchange Online using OWA does not show the folders. Unchecking "Show only subscribed folders" causes them to disappear." But they still show up if you right click on the account and click Subscribe. I have already opened a case with Microsoft and they say it's a client issue and not an Exchange Online issue.

In both my Inbox and my saved email folders, when I click on an end-to-end encrypted email, Thunderbird (v145) displays "Loading Message..." and then blocks with a spinning blue "working" cursor for on the order of 30-60 seconds. The Thunderbird dialog then appears to make some progress, as the windows seems to "flash" as if it's being cleared, but the email content doesn't appear. After about another 20-30 seconds, the encrypted email contents appear, correctly decrypted.

This long delay only occurs when I click on encrypted email messages, and it happens every time I click on an encrypted email message, and this behavior only started occurring in the past couple of days (correlated, I believe with Thunderbird updating to v145) so I think it's safe to assume the issue is with end-to-end encryption/decryption in Thunderbird v145.

I then click on cancel to get it off my email screen. However it continues to pop up whenever I try to get my email, even though the mail comes through, it says can not connect to server. Very confusing. Anyone have this issue?

After Windows installed an update in the middle of the night I can't open Thunderbird and I've tried uninstalling it and reinstalling with success.

It says: Thunderbird is already running, but is not responding. The old Thunderbird process must be closed to open a new window.

I've rebooted the PC, shut down the PC, ended the task and still nothing. It seem that Thunderbird didn't shut down correctly and the system still thinks that it's open and running. Anyone know how I can fix this issue?

Thanks,

Gregg

Running Thunderbird 140.5.0esr

This has been happening for a few weeks now somewhat randomly. The folders under Mail for one of my accounts keep moving around and are not in alphabetical order anymore. Most folders are OK, but a few either jump to the top of bottom of the list. I can manually drag them back, only for different folders to do it the next time.

The folders in questions are 2 levels down from Mail.

Hello, I recently cleaned up my mail account and deleted obsolete folders on one device. The folder has been deleted on the server, but Thunderbird on another computer still shows the folder. In the subscribe menu the folder is not shown. But when I try to delete it it throws an error "The current command did not succeed. The mail server for account <account name> responded: [NONEXISTENT] unknown source folder.". The error makes sense since the folder has been deleted on the server. Is there a way to tell Thunderbird to just remove this folder?

Thanks in advance!

Hello,

I created an event in the Thunderbird calendar, inluded 30 e-mail addresses of which only 19 calendar invites were sent. It sent the invites in the order of the recipient list and just stopped at number 19..

What could be the problem here?

Thunderbird version 140.5.0esr on Ubuntu.

Forwarded emails contain no signature, either above or below the forwarded email body.

No means exists in settings to specify that a signature should be in forwarded emails.

Thunderbird resists configuration for included signatures specified in the configuration editor.

Is there a reason that settings, such as columns, layout, ordering, folder colours, etc. are not retained in the msf itself?

I have to use multiple machines, so tend to have an archive that I share across them as the primary storage of emails. However, nothing is retained between machines which is a bit annoying when trying to colour code for easy visual cues. So it seems clear that this information is currently stored in the local profile, even though the archive data is a filesystem.

Hi, I am using Thunderbird on my Android phone and PC. When I send emails from my Android phone, the emails are sent but a copy is not stored in the "SENT" folder of my phone. This feature used to work in the past, but now it doesn't anymore.

How can I resolve this? Thank you.
