Thunderbird Community Forum

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

I have seen a thread about this, but the request remains unanswered. I am using iMap, for mail accounts in Thunderbird. Under Account Settings you can select folders to be downloaded, but they are only a preset few folders.

I wish to download the folders that I created on webmail. Thanks, 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?

Have deleted install pkg from W10 computer (PC). Figured if all was deleted new install would be easy. But, I keep getting message" Your Thunderbird Profile cannot be loaded. It may be\ missing or inaccessible"

If I have deleted all attempts at installing how can I need the profile? Wouldn't it be created in the new install. What specific files or folders should I be looking for? I have referred to "How do I find my Profile? and associated documents. and uninstalling the Firefox file from the MS apps list doesn't seem to clean this message trigger.

Frustrated after 5 tries...

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'm a retired IT Tech and supported MS Outlook with Exchange for years. Lately I've tired of the constant bickering between Google and MS that just seem to make using Outlook at home difficult. I've been working on Migrating from MS Outlook to Thunderbird v147.0.1. I had a large PST file with Saved Items and it's been a struggle to process all that but finally got connected to Gmail, converted/imported the PST items and then began working on Calendar. Finally got all that working and I'm now having trouble getting Google Tasks connected to Thunderbird. Google doesn't seem to be exposing the Tasks feed via CalDAV. Has anyone run into this before and does anyone have any suggestions to resolve? Thanks.

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.

Dear helpers,

I want to upgrade the hardware of a friend - and so I moved the homedir of the user to the new system, as I have done every time before in my life. But in this special case Thunderbird will not start with the used profile.

Thunderbird generally starts with e.g. the -P switch. But it will not start the default profile of the user. I tried to go this way concerning the versions 115 -> 128 -> 140 without success. I deleted all lock files, if there were any. I spent a lot of time with e.g. copilot - but it could not help me. I'm at a loss.

Is there any documentation with a kind of step-by-step instructions? Can you give me a hint, please?

Here are the details:

Source: linux mint 20.2 uma Thunderbird 115.18.0esr 11th of december 2024

Destination: linux mint 22.3 zena Thunderbird 140.7.0esr

Thank you in advance for your help.

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!
