Thunderbird gemenskapsforum

My wife has a computer that hasn't been used for about 7 years and it contains a lot of emails that she would like to have on her newer computer.

The older computer has an older version of Thunderbird which doesn't allow the Importexport ng extension to be added.

Although I've copied her old profile, I can't see how to extract the emails from it into the newer version of Thunderbird on the newer computer. Is it possible and if so, how please.

Thanks.

I have changed Thunderbird E-mail account from IMAP to POP3. My question is, How do I get all my E-mail folders from the IMAP into the new POP3 account. Nothing followed the changed accounts formats.

I have an Thunderbird email account both my wife and I use on phones, tablets and PCs. We use imap on phones and tablets, and pop3 on PCs. Occasionally when downloading the email to the PCs the download stops on a specific email and will go no further. All 3 PCs stop at the same email. IMAP can see the email that haven't downloaded, and if I delete with IMAP the email after the successful downloaded email, the pop3 Clients can download the remaining email on the server. This has happened several times and I don't see anything especially weird about the offending email. Usually some small graphics but no large attachment or anything odd? Any ideas as to what is going on?Version 140.12.1esr

I've used TB for many years, and keep it up to date. But it suddenly stopped downloads from my email server. Normally everything comes into my Inbox folder and after reading, they are either put into their respective folders or deleted. I had maybe 60 or 70 retained for later attention. (Like due pymnts)

I've tried everything I know, even the mail server connection, but somewhere in the process, I lost everything that was saved in the "Inbox" folder. I got to looking for the profile file, and only found 1 that was recently dated. Not sure if a rebuild would be advisable. Nearly all my (50+) folders show up as normal. Just can't find why the Inbox isn't recognized.

I tried using TB in both safe mode and troubleshoot mode, to no effect. I DO have win 7 Ultimate and hasn't ever been a problem. The error message I get is: "The mail server for account ***** responded with 'mailbox INBOX does not exist!' The name of the folder is "Inbox" as opposed to the capitalized version, but nothing has changed for years, and never been a problem. Go figure??

After _years_ of use and storage, I'm really hurting without it. Any help or suggestions would sure be appreciated. gshantz

With a new Thunderbird installation on Windows 10 Pro, I attempted to import my profile data from a Postbox on another machine. The process failed, citing two errors (see attached screen shot), EmptyDatabase Error: "blocklists/addons-bloomfilters" has not been synced yet Uncaught NS_ERROR_FILE_NO_DEVICE_SPACE: Component returned failure code: 0X805200010

The profile being imported is pretty large -- around 20Gb, so I wonder whether I have surpassed some capacity limit. I was doing this via the Import Tool on the Tools menu.

Porting my legacy mail folders is crucial. Any help would be greatly appreciated.

Home Mozilla Thunderbird (Not Responding) is all I see on the screen.

I have rebooted, reinstalled and still cannot get Thunderbird to start. I have not touched the C:/Users/.../AppData/Roaming/Thunderbird data (where I assume the problem is).

A while back I complained about this exact thing here: https://support.mozilla.org/en-US/questions/1401708 — thread's archived now so I couldn't reply there.

Ended up building a small add-on myself since nothing else out there worked anymore. It makes every global search open directly as a list, no more clicking "Show results as list" every time.

Free, open source, no data collection. Can't be listed on addons.thunderbird.net right now (Mozilla's paused reviewing new add-ons that use Experiment APIs), so it's a manual install for now. Apparently this is getting built into Thunderbird natively from version 154 (bug 580252), so this is really just a bridge until then.

Posting here in case anyone else still lands on the old thread like I did.

It was working fine on the new computer until yesterday. Now I get a pop-up box that says: ' Unable to connect The connection was refused when attempting to contact localhost.

The site could be temporarily unavailable or too busy. Try again in a few moments.

If you are unable to load any pages, check your computer's network connection. If your computer or network is protected by a firewall or proxy, make sure Thunderbird is permitted to access the web.

When I send an email, a window pops up that shows the sending progress. Emails appear to send and save to the sent folder just fine, but the window doesn't close and will remain open until I press the cancel button. Is it possible to fix this?

I have frequent problems with message filter settings and these problems have been occurring through several of the last Thunderbird versions. All message filters frequently lose "Move message to.." information. "Enabled" check boxes become unchecked "Run selected filter(s) on:... " specified file keeps changing.

This will make more sense if you look at the attached images first. If I create two one-hour appointments back to back on the same day--meaning the first appointment ends at the same time the next one begins (or with a 1 min gap), and then I look at my calendar in Week view, I'll see 2 full-column 1-hour blocks stacked one above the other as in the "1hr appt.png" attached. This appears to be the correct way it should appear.

But if the earlier appointment is only 30 minutes, they appear differently, as in the other image "30min appt.png". squeezed into two columns. I would like them to appear as a single, full column (as with the 1 hour appointments), which it does in the Day view.

Is this a bug? Can I change this behavior?

I've successfully connected to a hosted Exchange server through EWS and NTLM authentication (kudos BTW). But there is a problem - often during operations against EWS I'm presented with "Login to account XXX failed" "Login to server YYY with account XXX failed". I can ignore it (cancel) and it will work for seconds or minutes but eventually reappear. Sometimes it's very frequent, sometimes is here and there. TL;DR; connection works, I can read directories and e-mails.

From looking at development tools I see these scenarios: 1. POST requests return 200 always (no messsage of course) 2. Eventually a POST would return 401. Then Thunderbird issues a GET, it returns 401 as well but response includes header WWW-Authenticate: NTLM XXXXXX. Then another GET is issued containing header "Authorization" with the value from previous response. This time it gets 200 and continues without POST requests without a dialog. 3. Sometimes there are more POST requests with 401 (I assume in parallel) before a GET is issued and then I see a dialog. Sometimes it recovers (regardless of whether I cancel or retry), sometimes gets stuck with 401 with dialog reappearing each time it tries something. This case it's similar in sense that thunderbird issues GET with 401 and WWW-Authenticate header, issues another GET with Authenticate header but still gets 401.

If I had to guess I'd say the problem happens when POST requests are issued in parallel, not sequentially. OTOH it might be a problem at the server, but it isn't very likely.
