Thunderbird Support Forum

I have a Thunderbird on my old windows computer. I just installed it on my new computer (and I donated). I could have sworn that I had the import/export tool on the old Thunderbird. I desperately need to move some folders of emails from the old computer to the new one. I can't find a way to do that. I went to a link that said the import/export tool no longer works. I tried archiving the messages in a folder but have no idea where they went. Luckily I could undo that. What is the best way to move these folders of emails to the new computer? It was really easy many years ago.

My Yahoo IMAP account in Thunderbird no longer has any email showing in the Sent folder. There's plenty of mail in Yahoo Sent mail in the browser, but it's not finding its way into Thunderbird. I tried the Repair option, but I just get a typical message that I often see for Yahoo:

"The current operation on 'Inbox' did not succeed. The mail server for account Yahoo responded: [SERVERBUG] UID FETCH Server error - Please try again later."

The Yahoo account shows Sent mail in my iPhone. The Thunderbird Sent folder was seeing messages as recently as last week, so this seems to be a new problem, and I don't know if it's something that I did wrong by mistake. Thanks for any help.

Today (for example) I saw a message 'Downloading message n of 182 messages' (n increasing with every message downloaded but the message disappearing well before 182). According to the activity manager and my own reckoning 72 were downloaded. An incorrect number of messages to be downloaded has been shown every day since 26 April 2024 although my previous download was on 20 April when the number that day (and on previous days going back many years) was correct. I have included messages in the Junk folder in my reckoning. The account is POP mail server and my Thunderbird version is 115.10.1 (64 bit). Not life threatening but can I fix this or can a recent change be corrected as I found the number being downloaded figure useful when it was correct.

On opening Thunderbird every morning, ALL my folders are expanded and I have a lot of folders! I have A-Z and then many many subfolders within each folder. It's extremely frustrating as I have to collapse them all every single time. Is there a way of never having this happen again?

Hi,

Scenario: I have a custom domain with an email address, and have used mailbox.org and currently icloud to host my email. In both cases, the email address associated with my custom domain is the only one I use for everything, such as email, calendar, contacts, etc (x@er.com). Also in both cases, there is also a login email address to the email hosting service (i.e. x@mailbox.com and x@icloud.com respectively).

Issue: My calendar invites erroneously send from my icloud email address, rather than my custom domain email address. This appears to be by defaul and unchangeable. See 1/2 screenshot.

Settings: I'm on W11 Pro, using TB 115.10.1 (64-bit). For calendar settings, see 2/2 screenshot.

Background: With both providers, my calendar invites initially were being sent from the correct email address (x@er.com), but inexplicably switched to the being sent from login email address of the email hosting service after some time (about a year with mailbox.org, and a couple of months after migrating to icloud.com). This messes up my calendars, and I need to resolve it. Hopefully it's just something dumb that I'm doing.

What I've tried: On mailbox.org: When the issue first occured I put up with it for a few weeks then assumed it was probably mailbox.org and migrated to icloud. This appeared to resolve the problem at the time. On icloud, my calendar sync was setup in TB using add-ons, which worked for a couple of months and then the issue recurred. I've tried: 1. In apple account settings: I tried changing my apple-id to be my custom domain email address, rather than my icloud email address (didn't fix it). 2. I then unsubscribed from all of my network calendars in TB, removing the addons and restarting TB, as per https://support.mozilla.org/en-US/questions/1406255#answer-1568028 - I had to add a blank local calendar first before I was able to remove all of the network calendars. 3. I then added my calendars back into TB by using the direct URL locations, as per https://support.mozilla.org/en-US/questions/1406112 - when adding the calendars back, I tried using the login as both my custom domain email address, and also my icloud email address (didn't fix it).

Any help would be much appreciated.

Thank you.

This is what the message says. It got hung up after the DONATE message posted. i donated, but it didn't free it up.

"Unable to open the folder Inbox on robert@perless.com because it is in use by some other operation. Please wait for that operation to finish and then select the folder again."

Apple says it is a TB problem, not an Apple problem. Somebody please help.

I am running this computer for my late husband who left us in September after he fell off a 25' ladder at the age of 85. It still has all the information from his art. He was a sculptor who made large kinetic pieces.

Please help. Ellen Perless ellen@perless.com

Good day Mozilla vols! Has anyone else heard of, or developed an issue recently where TB will not delete multiple emails when selected? Previously, when I selected multiple emails for deletion and clicked "delete selected messages", TB would hang for a bit (while processing), but then all my selected messages would be deleted from both TB and my mail provider.

With timing conspicuously aligning to the 115.10.2 update, the multiple email delete functionality has broken. Now, when I highlight multiple emails to delete, instead of deleting them, TB marks them all as read, and only deletes a single email (the oldest email in the group I selected).

I saw one other question about this, but it was marked "archived" without an answer. Any thoughts/suggestions would be greatly appreciated.

Mail provider: gmail OS: Win 11 Security: Windows Security (old Windows Defender) TB client (now) 115.10.2 Troubleshooting mode (with controls reset and add-ons disabled) did not resolve the problem

Been using Thunderbird/Lightning for many years. In the latest update (115.10.1 (64 bit)), the EDIT button is not initially visible when I click on an event in my Calendar. In past releases, this edit button has always been visible in the pop-up window when I try to edit info in a New Event task. This happens SOME of the time, but not all. Any idea what changed, and is it possible to check out the code and change it back so when I double-click on an event, I see the edit button. At this time (not a big deal, but slows me down), when I go to edit an event, I have to move to a different monitor, resize the pop-up window so I can see the EDIT button, then finally click on it to edit the Event. In the past, the cursor immediately went to the EDIT button. Any info on changing this back the old way would be appreciated.

I run message filters to file messages from Inbox in specific folders. However for some of my filters that copy or move a message to a folder in Local Folders the body of the message disappears, leaving only the message header. Other filters set up in the same way work fine. The filters are usually on the sender's e-mail address. Any ideas for a fix?

There is an email app provided by xiaomi on my phone.What in the email sent by this app contains a special format of `Date` fields.It looks like that: `Date: Thu, 2 May 2024 05:55:12 UTC` It doesn't look like others' `Date: Thu, 2 May 2024 06:05:15 +0000` or `Date: Thu, 2 May 2024 10:35:14 +0800 (CST)`

but it is still conforming to standards (or is it only parsable by the JavaScript Date method?)

After I modified windows time zone and restarted thunderbird. all emails changed time so this is not a time zone problem.

But this email shown two different times in the preview and detailed pages at this moment.

So can anyone tell me if this is a bug? Thank you.

Hello, in TB there is the option of displaying certain appointments or all appointments, e.g. in the next seven days (above the calendar). This also works perfectly on my Windows computer, but unfortunately not on my Linux computer (Ubuntu 22.04.4 LTS, TB 115.10.1 (64-bit)). In TB on Linux, no appointment is displayed as a list at all. What could be the reason for this? Thank you! Niels

Hi, starting with Thunderbird 126.b02 (al least) there are very heavy perfoming issues. Beyond crashes it takes approximatly 10 seconds to open a specific email. Moving to another account is much more difficult: taking itself a much of time it takes supplemental time to open the INBOX.

Despite an Raphael on-dice-graphics I'm running a discrete Radeon RX 6700XT. HDD is far away from being over-lastet or running out of memory

Any ideas? Appreciated. Thx. B.
