Thunderbird-Hilfeforum

Good afternoon I have 2 accounts in Thunderbird - a gmail and a Yahoo. Both were running great from the time I set up Thunderbird about 2 weeks ago until yesterday when the gmail account stopped sending and receiving. The Yahoo account is still fine. I have not received a message in Thunderbird in my gmail account since, although I have logged in on the web and confirmed that there are incoming messages in my account.

When I attempt to send a message from the gmail account I receive an error message - "Add Security Exception". If I click "View" nothing happens. If I click "Get Certificate" the section "Unknown Identity" changes to "No Information Available". However, when I cancelled the message I noticed a new error message appeared - "Send Error Message" and when I returned to the main Thunderbird screen I noticed a new tab appeared "Certificate for smtp.gmail.com".

As you can imagine, I seem to be getting nowhere with this and as I am only an intermediate user with computers I don't know where to go next. Subsequently, I sincerely hope that someone out there is able to help me. Any assistance would be very much appreciated.

The following are my Thunderbird settings for the gmail account :- Incoming Server Server type : IMAP Mail Server Server name : imap.gmail.com Port : 993 User name : [myname]@gmail.com Connection security : SSL/TLS Authentication method : OAuth2

Outgoing server Description : Google Mail Server name : smtp.gmail.com Port : 465 Connection security : SSL/TLS Authentication method : OAuth2 User name : [myname]@gmail.com

A copy of the error messages as well as the Certificate are attached.

As described in [question] I am unable to install addons in Thunderbird: when attempting to install an addon, either via the in-app browser or via a file, a pop-up window appears for which "Add" and "Cancel" buttons do nothing (there is no way to move or remove the window without killing the process).

I am opening this question as this problem still persists over a year and many versions later.

Thunderbird V. 115.11.1-1 on 6.9.3-arch1-1 with Sway WM

I have been successfully accessing my icloud account with thunderbird on Windows 10 for years and then on Tuesday (June 4th) it went weird. All I am left with is thunderbird's cached inbox e-mails. If I try to update the list of new e-mails, it just sits there with no errors reported. If I try to read some cached e-mails I can see the full text. (I am setup to always read plain text), but for some, I just get whitespace. I see "myname@icloud.com connected to imap.mail.me.com..." on the status line for most folders, but some just clear that status message.

Thunderbird. When I move an email it does not go to the new folder, it disappears. Ctrl-Z (in the same session, only) will bring the message back.

This is a serious and fundamental problem for an email reader. And there is no direct channel for getting help with such a fundamental problem.

The messages are not misfiled, they do indeed disappear. Thunderbird 115.11.1 (64-bit) on Windows 11 Pro 10.0.22631. OUTLOOK does not do this with the same mail accounts.

I ran into an error on my Windows 11 PC. If I add an attachment via the system menu called up by the right mouse button, the size of the attachment is displayed in terabits and cannot be sent :-)

In Outlook you can forward an appointment that is not created by yourself to someone else. In Thunderbird this option seems not available, or is it? Adding attendees to an event that you did not create yourself does not work.

Blocking remote content by default is a very positive security feature. But needing to add each and every email address individually is NOT optimum and wastes a lot of time. We really need a method to globally allow remote content from specified domains. For instance, it would be handy to allow remote content from any/all email from IBM, but I certainly don't want this for gmail.com addresses. This seems like a very simple improvement to code.

I am not receiving emails and when I try to send an email I get a warning "Sending of the message failed.Peer’s Certificate issuer is not recognized.The configuration related to smtp.themessagingco.com.au must be corrected" I have made sure that the account information for incoming and outgoing mail is correct, but that is the limit of my understanding of what I can do. How can I correct this problem?

I have just completely reinstalled Thunderbird v115.11.1 after uninstalling the previous installation. There are two problems, possibly linked to a faulty or missing setting.

Remote images will not display, even after specifically enabling remote images for each email, or after turning on "display remote content" as a default. Also it claims there is a potential security threat with Thunderbird's own web addresses: "live.thunderbird.net." and "addons.thunderbird.net.".

I have attached screen-shots of the error messages, and of a thunderbird email that fails to display its images.

Is there a way to play a certain continuous tone when an incoming mail from a certain sender (e.g. xyz@example.com or just @example.com) comes in? That would be an extremely useful function, e.g. if you are waiting for particularly important and urgent mails and, for example, want to be woken up in the night when this particular important mail arrives.

The folder "popstate-1.dat" appeared under my email account below Inbox, Drafts, Sent, Archives, Junk and Trash. I have attached an image showing the folder located below Trash and above Local Folders.

Can it be deleted? Is it serving a purpose?

I recently deleted old messages from the various Local Folders folders.

Thank you.

I maintain a "Favorites" folder view as those are the folders I use 95% of the time and I have a very large number of historical folders I need to keep around but don't need very often. Trouble is, when I create a new folder, the creation dialog doesn't offer the option to make the folder a favorite so that it disappears after creation. I have to switch to the "ALL folders" view and then right click on the new folder and check the "favorite" box and then go back to favorites view.

It would make life so much easier if there was a favorite checkbox on the creation dialog.

Thank you.

I've just started getting error messages that I need to enter my password to send emails. I've tried that but it still keeps saying unable to connect to the server. This has been happening for about two days now. I've tried updating Thunderbird, restarting Thunderbird and restarting my PC. None of this has worked. I made no changes to my system, software or home network. Any help would be appreciated. Thanks, Dave

When I delete an email it immediately diseappears from the view, but if I have the "Unread" filter active and I mark an email as "read" it remains there until I switch the "Unread" filter off and then on again. Quite impractical to me.

My service provider is QX.net which uses Magic Mail web email. I have Firefox 115.ll, 64 bit. I have Thunderbird 115.11.1, 32 bit.

The Magic Mail on my Server shows 253 unread messages. I have identified some of those 253 messages in my Thunderbird folder and they have been read, and are shown as read in Thunderbird. There seem to be 3 different dates involved. This is a concern as it is unacceptable not to receive all of my messages.

Please advise what I can do to address this so that I receive all my messages and so that when I have read them they are shown as "read" in Thunderbird and in Magic Mail.

Thank you so very much for any help.

Hi. I have 3 e-mails. recently I could not receive on another e-mail. I called my cable tech. he said that thunderbird hadupdated and some users had problems. He had me change my port to 578. I did and now the same e-mail will send but not receive. so three of my e-mails will send and only 2 will receive. I am very ignorant with computer use. I use a flip phone for travel. thanks dan
