Thunderbird Support Forum

I keep getting "can't connect" message and I have to enter my password for outgoing mail. Incoming comes through no problem. How can I get Thunderbird to remember my provider password for outgoing? They obviously already have it for incoming.

I would like to change my account settings for my hotmail account, but when I try to change from Normal Password under Outgoing Server (SMTP) there is no option for Oauth. Is there something I can do to enable this option.

A long-standing university email account that I accessed through Thunderbird was recently mistakenly deleted by the institutional administrator and all its contents deleted. The institution subsequently established a replacement email account for me, but the institutional Help Desk said the emails from the original account had been erased and could no longer be accessed from their server. Fortunately, I had Thunderbird configured to save all my emails on my local machine, so that even though I can no longer log in to the original email account, I can still view the emails in my Thunderbird installation (i.e., open and read them), even though every instance of starting up Thunderbird calls for me to supply the password for the original account (which I can no longer do). So I just close that dialogue box and can still see the emails stored locally on my machine.

I would like to move (or copy) these emails to a location where I can still access them off line and view them in the original organizational scheme (if possible), under the headings "subject," "correspondents," and "Date." But the Thunderbird "archive" feature seems to require that I be able to log on to the institutional server under the original account, which I can no longer do. The only existence of these emails is on my local computer.

Is there a way for me to preserve these emails as an accessible archive/repository so that I can continue having access to them, even though they are no longer in a functioning email account?

Thanks for any suggestions/help.

Hello- I want to add some verbiage before my business card that I have add to my Signature. see image - How do I include the Warm Regards, name, number? I did add on "advanced composer" but cannot find how to use it in FF Thanks for the help

I have received an email from Microsoft advising that from a date in September third party apps will no longer be able to access outlook email accounts. Does this mean I will no longer be able to use Thunderbird - which has been my preferred email client for many years? Thanks Nigel

Followed the instructions in the article and cannot send email (SMTP error) "Login to server smtp.office365.com with username xxxxx#outlookcom failed"

Tried a new profile - no change Followed directions for using config editor and deleting two items - no change Could go back to original settings (turn off OATH2) but have to get it working by Sept so might as well slay the beast now.

Outlook says that it will no longer let third party mail apps like Thunderbird to access Outlook email as of September 16, 2024? What do you recommend?

"Action Needed – You may lose access to some of your third-party mail and calendar apps

Update your sign-in technology before September 16th, 2024 to maintain email access.

The safety and security of your information is top priority for Microsoft. To help keep your account secure, Microsoft will no longer support the use of third-party email and calendar apps which ask you to sign in with only your Microsoft Account username and password. To keep you safe you will need to use a mail or calendar app which supports Microsoft’s modern authentication methods. If you do not act, your third-party email apps will no longer be able to access your Outlook.com, Hotmail or Live.com email address on September 16th.

What do you need to do?

If you are receiving this email, you are currently using an email or calendar app that uses a less secure authentication method to connect to your Outlook.com email account. You will need to upgrade your third-party mail and calendar app to a version which supports modern authentication methods.

Microsoft provides free versions of Outlook for your PC, Mac, iOS, and Android devices which can be easily downloaded and connect to your email account. Using an updated version of an Outlook application will ensure you are connecting in the most secure way.

How can you set up your Gmail, Apple Mail, or other third-party mail application?

Various non-Microsoft applications will have their own steps for connecting to your Outlook.com email account using modern authentication methods. See our help article - Modern Authentication Methods now needed to continue syncing Outlook Email in non-Microsoft email apps. However, you may need to contact the creators of those applications to provide you with instructions. In many cases, simply removing and re-adding your account with the latest version of that application will configure it to use modern authentication methods.

when clicking an email link this is shown

"Thunderbird is already running, but is not responding. To use Thunderbird, you must first close the existing Thunderbird process, restart your device, or use a different profile."

How do I make Thunderbird instead open a new email?

This is on Fedora

My Thunderbird Version: 115.12.2 (32 Bit)

Microsoft is changing the authentication method for outlook mail to OAuth2. I follow the guide here,

https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202

And I get to this screen - but my version of the program does not have OAuth2 as an option (see attached image).

Thanks for the help.

Short background: Critically low on disc space. Windows pointed out a potentially extraneous 8.5gb NS3TMP Thunderbird file. Extensive Googling convinced me it would be safe to delete this file. To be safe (HA!) I first copied it to an external drive just in case things went south. They did.

After the copy, I went back and deleted the NS3TMP file. However, much to my horror, instead of deleting 8.5gb as expected, 30.5gb got deleted. After that, Thunderbird would not start claiming my profile was missing.

I copied the 8.5gb backup file back to its original place. No joy. Same message from Thunderbird.

At this point, I recreated my profile pointing Thunderbird to my Outlook email account.

I could now sign into Thunderbird and T'bird started populating the inbox and sent folders, but only partially. Worse (MUCH worse) my critical Thunderbird local folders were nowhere to be found. I attempted several folder recovery procedures to no avail.

I confess, I do not know how Thunderbird works its magic behind the scenes. Were my local folders part of the surprise 30gb file deletion and thus gone for good? Would the original emails that had been dragged into the various folders still be sitting on Outlook's servers?

As I said, totally self-inflicted but hopeful there's a road to recovery.

Any assistance or consoling words would be much appreciated.

Hello,

I downloaded Google Takeout file, I was able to see it in my computer. But when I tried to import the mbox file into Thunderbird, it's not showing.

Please help.

I'm trying to read some old emails in an account from around 20 years ago that I have kept in Thunderbird the entire time. I stopped using the account, but kept it configured as it always had been with the old email saved in it. The emails are in several folders in Thunderbird, and I can see them listed when I select a folder, but the content of most of them is now invisible. For many years I upgraded Thunderbird and they remained visible, and I naively assumed that would always be the case. I think the visibility problem happened after a Thunderbird upgrade sometime within the last few years. Strangely, a few emails are readable. I think they're the last ones I viewed before I became unable to see additional ones I select to view. I believe all the data is still there, but I don't know how to read it. In the file system, here's what my Thunderbird profile Mail directory looks like:

/Users/myMacUser/Library/Thunderbird/Profiles/my-random.default/Mail account.server.name - TB Email Folder 1.sbd (empty directory) - TB Email Folder 1 (no file extension, apparently the file containing the email data. File sizes suggest they contain data) - TB Email Folder 1.msf (the index file, apparently readable) etc.

I'm using Thunderbird 115.12.2 on MacOS Sonoma 14.5. I tried several types of exports with the ImportExportTools NG extension, but it just exported zero byte or blank files for the invisible emails.

How do I read these folder data files?

Hi, I've received the email below from Microsoft today.

I have 15 email accounts linked to Thunderbird mail and use up to 5 of them daily. Sometimes 'instant' communications on one or more of my accounts can be important.

Will Thunderbird mail still function in the same way from 16th September?

I apologise if this question has been answered somewhere else. I searched but could not find it.

When I launched Thunderbird today, it would not connect to one mailserver: imap.mailfence.com. At the same time, Thunderbird said to restart to update to 115.2.2. After updating, it still refuses to connect. There is nothing wrong with Mailfence and I do not find anything wrong with the configuration settings in Thunderbird. I even tried to set up my Mailfence email account again but it failed because it could not connect. Ideas? Thank you.

This there a "Global" Message Filter Rule where you can change an Apply Filter When: to ALL your Message Filters?

Example: I'd like to add "Periodically, every 10 minutes" to ALL my current Message Filters. Currently, it looks like I have to Edit each and every one of them?

Thank you in advance.

My son has a Hotmail account that he accesses (of course) in Thunderbird. Yesterday he received an email from Microsoft that seems to suggest that he will not be able to use Thunderbird to access this account after 9/16/24. Is this true?
