I have an email address and I want to migrate those emails to a gmail address. The problem is that I have around 2300 emails. I'm copying about 200 emails to the gmail address. The problem is that is taking too long and it's not copying all of them.

What if I copy all of emails wait to sycronize it and then copy it again? It will work? Or is there another way to do that?

After updating to 153.0.1esr(aarch64). the SEND button has disappeared. There's no way to send an email. (I can receive emails.) I am a Mac mini M2 Pro. OS 26.4.1

I cannot find a link to download a previous release of Thuderbird, which was working fine until this update.

So, I recently got rid of Spectrum as my internet & email provider. I have used the Archive function to archive all the emails from that account but still need to be able to access them after I remove the spectrum email account from Thunderbird. Does Archiving the emails keep them accessible or do I need to so something else. Further info, all of my emails are downloaded to thunderbird and not kept on the server, so they are physically on my computer inside thunderbird program

Hi there,

I'm wondering how I'm able to open open an address book file (Thunderbird) with a separate program other than the Thunderbird Email Client?

Any Ideas Please?

Sometime ago, Thunderbird stopped being able to connect with my GMail and Hotmail email accounts. I guess this had something to do with the change to OAuth authentication. I then switched over to Yahoo accounts which worked perfectly until last night when I installed the latest update, i.e. 153.0.1esr (Meadow). Now, I cannot connect with ANY account whatsoever. Thunderbird just stopped working in my two Windows 10 laptops and it does not seem to work on the Windows 11, either, although I have only tried Gmail accounts on that one (without the update), as I cannot possibly be left without an email handler.

If I try to download my emails, I get a screen that tells me that I should “Turn-off ad blockers“ and “Enable JavaScript“ in my browser, but I have tried several (4) browsers as default with the same result. I don’t have either ad blockers or cookie restrictions in any one of them and JavaScript is enabled in all (it is now by default).

I have downloaded and installed “eM Client” and it works *perfectly*. However, I would loathe to have to abandon Thunderbird and get used to an entirely new program, but which is what I will have to do if this thing is not resolved ASAP.

As mentioned, I think there has to do with the OAuth authentication system.

I have even tried ChatGPT, without success!

And there is no way to revert to the previous version !!!!!

Please do something NOW, or it is, regrettably, goodbye Thunderbird!

What is the best way in TB of organising the storage of email messages on my local storage device:

• Many folders/subfolders, each containing a limited number of messages?
• Few / One Archive folder containing all messages, each message tagged with one or more tags for easy search/retrieval?

I would prefer the latter, but I am unsure if there are any limitations to how many messages that can be stored in one folder i TB.

• Are there any practical limitations regarding the no. of messages in one folder?

On T-Bird start up I'm given a list of (originally) four Profiles. Currently I only use Profile Three, but on start=up today it is not there. Doing the usual searches does not list it, only 'default', 'new user' and 'profile two'. Is there any way to recover it?

The issue has been "An error occurred connecting to mail.mediacombb.net:993." on the server page, where you can "test connection to server" in Account > Server Settings > Security Settings. I get the same error message for each four different accounts. I have no problems with the other two different accounts not associated with Mediacom (MC). I contacted MC and they said my settings were correct and to contact TB. I have read several posts with no real solutions except that was resolved through an update. I plan to switch to a different Linux distro later. I am currently using Big Linux Manjaro with the latest update. Note that I had no problems with TB until last month. I do not do the uninstall/reinstall apps unless it will resolve my issues as a last resort. Second, sometimes I receive MC e-mails and did not run the "test connection to server," then until today while troubleshooting for several hours. I was trying to send out an e-mail, which I had no problems last week. I already went to Account > Server Settings > Advanced and changed the "Maximum number of server connections to cache" from 5 down to 1 with no luck.

  The e-mail server settings are:

imap.mediacombb.net 993 SSL/TLS Normal Password and smtp.mediacombb.net 587 STARTTLS Normal Password They have not been changed since I switched from windows 10 to Zorin 18 to currently Big Linux Manjaro. I attempted to locate a method to check if the server settings were correct via Terminal. M$ Outlook has a test page that you can send to yourself or another e-mail account. Last, MC tech informed me that M$ Outlook is more friendly than TB. I know that I have used M$ Outlook for years and rarely had any connection issues unlike TB. Unlike Evolution, which was my first after M$ Outlook, TB is much better and easier than Evolution. Thank you in advance for your time and advice.

I need a filter on a message to FULLY FINISH before a next message starts to be filtered. The "help" (quotes because it's an abyssal crap) says that simply ending the filter with Stop Filter Execution does it - but that's simply NOT TRUE: calling a console program in the filter, I can see five DOS boxes opening at the same time with five messages matching, i.e. the filters on the next message DID NOT wait! So... what can I do??

All of the above is because I'm getting "Too many simultaneous connections on the server". I'd like to limit the concurrency, but it only seems to be possible in IMAP, while this connection is a POP. Why only IMAP??!

As in the subject, my computer has sound everywhere else but, despite 'play a sound' still showing as ticked in general settings, no sound happens when an e-mail arrives. And, in general settings for 'when a new message' arrives, I can hit the Play Button there and the sound happens. How do I fix this?

T-Bird is Freezing (Hang?) from start to freeze was 5 minutes and a few seconds. Have turned off hardware acceleration and now it freezes at just under 5 minutes. Have put on updates. Currently 153.0.1esr (64-bit). I have captured profile, and re-installed and picked up the profile. Still freezes. Turned off AV. Still freezes. I have compressed and "repaired" all folders. Still Freezes. I forced folders to get rid of anything older than 30 days. Still freezes.

I have been running the task manager, and T-Bird in frozen state is only using 4.3% of CPU at most. I do not see any slowdowns for any other program. So this is not a CPU constrained problem. And it certainly is not memory constrained.

All this started within the past month and I think it was after I put on an ESR update (don't remember which one).

I can kill T-Bird and start it and it will get mail if any, and will function for about 5 minutes and then freezes (or hangs). The system is set to fetch mail on start up and then every 27 minutes. I am not using Account hub (and don't know what it does).

One oddity -- This is a W11 Home system, and Mozilla keeps saying it is a W10 system. Could this be the problem? Wife is running a lesser laptop. It is also running T-Bird, but her O/S is a W11 Pro and she is not having this problem.

Hi! I am having an issue with displaying sent mails. As you can see in the screenshot (cropped for privacy), I have selected the option to "Place replies in the folder of the message being replied to", which to me means that eg. a reply I sent will both be shown in the "inbox" folder in the message thread, as well as in the "sent" folder. However, it only shows up in the "inbox" folder. Why does this not work?

Thanks!

I'm running the current version of Thunderbird on Windows 11 Pro. Several time in the last few weeks I have noticed periods where I don't seem to be getting mail. When I close Thunderbird and restart it I get batches of 10-20 email messages that had been delivered to my shaw mail account, but which Thunderbird hd stopped downloading. There were no obvious messages that it had failed.

Thunderbird had been working great for both of us until after my wife stopped checking her emails for a couple of months. When she later opened the program her inbox started downloading hundreds of emails (very slowly) until her inbox contained well over a thousand. I started to delete the unwanted ones but it went very very slowly. I finally whittled it down to a few hundred but the program continues to run very slowly in all phases. In one instance, it took 11 minutes to delete 39 messages. Downloading and sending are not much different. I've done virus scans, checked settings, restarted the computer etc., all to no avail. And when we switch users, my Thunderbird email runs perfectly. I also contacted my internet provider (Spectrum) but they said it had to be a program issue. How can I restore my wife's email to normal function? Thanks, Joe S.

Hello,

Every now and then Thunderbird pops up the notification in the screenshot. Can anyone tell me what it means and if I should do anything about it?

Alan.

My Windows 11 was recently reinstalled to factory settings, which uninstalled Thunderbird but saved my mobx files. I used Thunderbird exclusively to view older emails that are stored on my PC as mobx files. I do not use Thunderbird as an active email client. I reinstalled Thunderbird, but have been unable to get it to find my mobx files that are stored together in a folder.

I had this issue some while back, then an update resolved it. Seems another update has brought it back.

Having just updated, still on ESR, I find that I now have 2 folders named "Spam", but in fact looking at the folder properties 1 is actually still "Junk".

The images explain it well.

As in the past, I'm unable to correctly rename the second Spam folder back to Junk.

It has to be the update that caused it (as previously).

When can I expect another update to resolve it?

Hello - new forum user with some previous familiarity with Thunderbird. I'm looking for advice on mail import from Outlook (M365) on Mac OS. I will only be using TBird for accessing historical mails in future rather than as the main mail app going forward.

I have installed Thunderbird and looked at the Import Tool but it doesn't list Outlook as an option. I've looked through the Import Tool support pages and I can see Outlook is an import option but it only seems to appear when I filter the web page based on Windows 11 rather than Mac OS.

Am I able to use the Import Tool on Mac OS with Outlook?

I'm using Mac OS Monterey 12.7.6 and have Thunderbird 153.0.1 and Outlook for Mac 16.89 (M365) installed.

If the Import Tool isn't available, is the next best option to drag individual folders from Outlook to the Mac desktop to create MBOX folders and then drag those into Thunderbird?

Thank you in advance.
