I need to import my mail messages, exported from Mac OSX Mail, into Thunderbird on Windows 11. I have 2 versions of the Mail exports: i) i backed up the Mail folder from the System folder These are [ .emlx ] files in [ .mbox ] folders ii) I exported direct from the Mail app These are [ .mbox ] folders

Thanks for any advice I can get, Steve

Greetings.

For many years I have used Thunderbird to send and receive mail through my Outlook account (while happily donating to Mozilla).

A few months ago, every initial attempt to send a message abruptly started to fail, generating the dreaded notice that “the message could not be sent because the connection to Outgoing server (SMTP) smtp-mail.outlook.com timed out.”

What is odd is that if I keep trying to send, the message always goes out eventually -- sometimes after only two tries, sometimes after ten tries.

Thus, my Outlook account works, my Thunderbird settings work, the SMTP server works -- but only at random intervals.

The problem has continued through several Thunderbird updates, including the current one (147.0.1). I tried changing the server to smtp.office365.com and got the same performance.

I am on MacOS 15.4 and am not running any third-party antivirus or firewall product.

My thanks to anyone who has insight into this problem.

This might also belong under accessibility. Or how to organize the screen? At this point I cannot get some messages because there is no space left for it. This has happened gradually but now its impossible. I will attach a screen shot to show the problem. (I would have a tiny bit more room if I could get rid of that line of tags since they come on a dropdown anyway. Thank you so much,

I want to change the folder to which I currently send my spam filters on my Mac. I understand how I can edit them individually and handle new filters, however I have several hundred accumulated filters created over the years and doing so individually will be very time consuming. Is there a method I can use to change all existing spam filter's destination folder in a single step. I know a bit about using Config Editor, Chrome css, probably just enough to get my self in trouble. I see several spam filter files within the Thunderbird folder, but not sure if they are germane.

Any help will be greatly appreciated.

Hi, I did something stupid. I accidentally deleted an entire year's worth of emails. I was in the process of archiving them, and mistakenly thought that the originals had been left in the inbox. I thought I needed to re-archive them, so I deleted the copies from the archive folder, and then - this is the stupid part - emptied the trash in the archive folder. When I went back to the inbox to re-archive the emails, I realized they were no longer there. I have not compacted the folder. Is there any way to recover the deleted emails?

While trying to locate the ID#s for all 15 different email accounts managed by my TB desktop app, I discovered that there are two instances of a gmail account, but with different ID#s (although only one appears in my home screen). I've found no way of determining which one is valid, and I can't risk losing my main gmail account if I try to delete one and choose the wrong one. Does anyone have any ideas I might try, to determine which one is the "extra" and how this happened? I've tried looking at the source code for emails in that account, but can't find any ID# referenced there.

I am using T-bird on a Mac. I set up for a gmail account. I can send emails but do not receive replies, etc. I noticed there is no mail inbox for the account. Settings appear correct. Any thoughts? Thank you.

I am so annoyed, MS clearly sabotage this to push people back to their horrific software! I am so against that idea I lost an entire full work day today trying to do something SO simple, to install Thunderbird (for a friend) and connect it to MS365 email address.

It's IMAP, it should have taken SECONDS! It did create it, pulled in tons of email, but refuses to SEND any! I tried every single suggestion I could find online, going back years. NOTHING works! All i get every time whne sending email is : "Login to server smtp.office365.com failed. "

Does anyone have a magic cure, 6 solid hours of this and I still refuse to give up hopes of making Thunderbird the active mail client! Thanks

I am getting started with TB and Exchange with the OWL plugin (https://services.addons.thunderbird.net/en-US/thunderbird/addon/owl-for-exchange/versions/). None of my filters seem be working. From what I determined from ChatGPT, certain body-oriented filters aren't supported. However, I'm just trying to do a simple filter on a sender (see attached image), which as I understand it *should* work.

Can someone confirm that filters like this either work or *don't* work for you? The OWL docs are very light on this: https://support.beonex.com/help/en-us/4-features/23-unsupported-feature

Thanks in advance!

I have two emails linked in Thunderbird. My default one works fine, but my secondary one started opening emails wrong yesterday. Every email I open, instead of just being able to view it/read it, it opens it into a composing email (like I am replying back to the email or even replying back to myself instead of just trying to read it) I looked at all of the settings between the two accounts and can't find any differences. HELP!

I have Thunderbird 142-esr on a Windows 11 computer with two users in separate Windows users account. The second user (my wife) suddenly had her gmail login stop working on TB, even though it continued working on all other devices. The symptom was that the inbox would hang trying to log on to gmail, although no error messages appeared.

My account worked normally throughout this time.

After trying less destructive fixes such as closing the application, logging off, and restarting Windows, I guessed there was an issue with her account, possibly a corrupted file. So I deleted her gmail account. When I tried to create a new account, TB accepted her credentials and the Google login came up. I successfully authenticated to Google, but installation failed when I returned to the TB new account screen. After a long wait, TB issued an error message saying the password or user name was bad.

I did two tests to isolate the problem. First, I attempted to install my wife's gmail account in my Windows TB instance. That failed in the same way. Second, I attempted to install my gmail account on her Windows instance. That worked. I concluded there was nothing wrong with her instance of TB. I thought it might be an issue with her password, although Google has never asked her to change it, and there haven't been issues logging on outside of TB. Her password did not meet Google's current requirements, so I changed it to 12 characters, mixture of upper/lower case, numerals, and special characters. That worked.

Unfortunately, during the process, I lost her settings, and it took a while to recover them from backup media.

I'm posting this more to ask if others have experienced such a problem than as a request for help, as I think the underlying issue is now resolved. Because it may be some kind of malignant interaction between TB and gmail, I thought it might be worth reporting as well.

I have been using Mozilla Thunderbird for decades and they have even contributed a small amount of money to Thunderbird periodically. Just within the last two or three days all of a sudden I have been unable to send emails with my phone. I receive emails, but I do not send them. So I opened up a laptop where I did not have Thunderbird and set it up properly through Spectrum using the incoming and outgoing servers as mail.twc.com. and yes, just like on my phone. I continue to receive new emails, but even with the laptop I was unable to send an email. I received the message"send message error sending a message failed. The message could not be sent because the connection to outgoing server smtp mail.twc.com was lost in the middle of the transaction. Try again."I contacted Spectrum twice and both times they had me try to send a message through their Web server spectrum.net and that message did go through. Of course then their response is that this has to be a problem with the third-party app meaning Mozilla Thunderbird, and they can’t help with that at all. I sure would appreciate some help because I hate to walk away from Thunderbird as well as change my email address after all of these decades.

I am updating from an old iMac to a new MacMini.

My new macMini does not seem to like my old Thunderbird program so I have downloaded a current version. 

How do I transfer all my old email contacts and old emails to the new platform? I am, in no way, technically savvy so I need simple answers, Many Thanks, John

I really have given up on Thunderbird, even though I have been a loyal supporter of the product for many years.

For the last year I have had to bypass Thunderbird and read my emails either on my mobile or directly from the BT server, which is how I am writing this mail.

My problem is , although I can view my mail perfectly on my mobile and of course on the BT server, Thunderbird seems totally incapable of transferring the mail to the Thunderbird inbox.

Thunderbird is not able to show the text and any images, all I get is a mail with a number of boxes, no pictures or anything of any use.

Is this since a Thunderbird 'update' or what, I don't know.

A little while ago I posted this problem and only got one reply from an 'expert'/community which failed to solve problem in any way.

I have also lost many of my earlier mail

Is it time to abandon Thunderbird and change to the dreaded Microsoft email package?

Yours faithfully in great expectations that someone somewhere most know how to fix Thunderbird

I have been dealing with this issue for the last several thunderbird versions. I am currently running 115.18.0

Everytime I try to configure an existing gmail account for thunderbird via File -> New -> Existing email account

I specify my Name and gmail email address, then password for the gmail account.

The google authentication pop up launches " Mozilla Thunderbird wants to access you Gmail" and I click "Allow"

As soon as I click "Allow" I am asked to download a file.

Google gemini says this file is a sign that Oauth is not being accepted by thunderbird.

What I have tried. I verified Thunderbird is set to accept cookies I have verified there are no previously stored gmail passwords (as this has never worked) I have changed my default browser from Firefox to Brave and verified the same behavior

please help, Thunderbird has never been able to connect to gmail when running on this Ubtuntu install.

When I reconcile my checking account each month, it's handy to be able to search my e-mail for the amounts of transactions that I can't identify by name alone. Gmail allowed me to do this. Thunderbird, for some reason, doesn't. Anytime I search for a numerical value (e.g., "36" or "9.58"), Thunderbird returns no results. Why are numeric strings not searchable? Is anyone working on this deficiency?

I started getting this problem about 6 months ago. I have used Thunderbird on Linux for years with very few problems until about 6 months ago. What happens is that when I send a message I get a dialog box saying sending and it will hang there for a long time, sometimes permanently. The size of message doesnt matter. Sometimes I can click on cancel and then retry and I am sometimes told it was sent but not saved. Sometimes it did not get sent at all. It is getting more and more annoying. It seems to happen after long periods of inactivity. Its not DNS, I have changed settings and DNS servers make no difference. I even went through and deleted lots of email and still it persists. I am running no extensions.
