Thunderbird Support Forum

On powering up my PC this morning, opened Thunderbird and everything was gone - email settings to my various accounts, settings, calendar, addresses etc nothing is left at all

All I have is a basic screen : "To set up your existing email address" etc

Like all of us, I get bombarded with spam emails. So I set up filters to separate the "definitely spam" from "possibly spam". I've been doing this for many years now. But recently, maybe for the past few months, I'm finding that these blacklist filters aren't working anymore. The filtering failure seems to be getting worse as time goes on. And, yes, I do a match on "any", but that still doesn't work. As I said above, my filtering rules used to work just fine, but possibly a new Thunderbird update several months ago broke filtering?

Also, is there a way for filtering on the message content URL? I find that sometimes that's the only way to distinguish spam.

From the article "Microsoft OAuth Authentication and Thunderbird in 2024" there is a screenshot showing a OAuth2 option for the SMTP server setting with STARTTLS connection security. It does not appear for me. There are only the five options, as shown in the screenshot. How do enable the option to be available in the drop-down list or set it?

The available options are:

No Authentication Normal Password Encrypted Password Kerberos / GSSAPI NTLM

I am on Thunderbird version 115.12.1 (64-bit), Windows 11, version 23H2, build 22631.3737

I just downloaded and installed Thunderbird.... I fire it up and the "three lines" button I need to click to add my email account details does nothing. So the software is not doing much at the moment. I don't know what to do. I uninstalled. Restarted...and reinstalled...but this did not work. What am I doing wrong here?

Do I install the 64bit option or 32bit ?? The installer gives me a choice.

After installation on the new M3 mac, I will be migrating my Thunderbird profile from a 2021 iMac that runs BigSur on Intel silicon.

I'm anticipating updating the iMac to Sonoma, but long experience has shown me that major s/w version upgrades are often very unfriendly to 3rd party s/w apps&data, so I wanted to get my tBird profile (all my mail history) working on the new Mac before doing the major upgrade on my iMac.

Just got home from vacation and it looks like I left my computer running for a week. Looking for an email and noticed that many, many emails from my saved subfolders are missing. Does Thunderbird automatically archive or something? I have never archived purposely. I need to know whether to use my backup program to try to retrieve these missing emails or to get them from my profile. Instructions in very easy explanation, please. I've tried to search this on the internet, etc. and I'm just lost and panicking. How can I tell if they were archived or not? I've found my "profile" but I can't tell what, if anything, to do from here.

I am using Thunderbird 115.12.1 (64 bit) on Windows 10 with the email account set up as POP3 for the Gmail account

I have a subfolder under an Inbox (Gmail account) that is no longer showing up. If I search for an email address from a sender that was in the folder, I get a list of emails showing the dates and subject, but if I click on the email, the tab that opens is blank.

My PC crashed, but I can't say for sure when the folder disappeared, other than I know it was there 4 days ago. It the the only subfolder that is missing.

Any help is appreciated. Thanks

I've used Thunderbird for years using a POP setting; Network Solutions would prefer that I use IMAP. I don't know the difference, but they must and prefer that it be IMAP (netsol-imap-oxcs.hostingplatform.com) (PORT: 993. When bringing up the settings in my mail account, it doesn't allow anyone to change that field. What can I do? I want to use Thunderbird; because of this particular setting I haven't been able to, and must instead log on to Network Solutions and go through their email interface. Thank you.

Hopefully this will reach Thunderbird support though I know Mozilla no longer supports this but the Thunderbird team does.

I would like to install Thunderbird on a MacBook Pro 2024 which I assume is running Os 14.5. It is not clear to me what version, if any, can be installed. I have used Thunderbird on Windows for many years but now wish to install it on this Mac.

Thanks,

 John

I was stupid and loaded down what I thought was an updated version, 115, of Thunderbird. Many of the folders with saved emails has dissapered. How can I get them back? Why is the number of saved emails shown on some of the folders. How to make the shown number to dissapear? How can I take away old emails in the infolder. In the previus version was that possible. I had to make all accounts once again. Shall it be that in an update? How can I get back the previous versin? I am not pleased with this new 115-version.

Regards Thomas

Please advise what settings will work with Thunderbird for all NETWORK SOLUTIONS imap and POP accounts Also please advise the proper settings for all AOL accounts IMAP and POP

I am trying to setup an Outlook account on Thunderbird and I get an error: "Unable to log in at server. Probably wrong configuration, username or password." I have an existing Outlook account which I am able to use on the Outlook app on Windows, the Android app and the web version on outlook.live.com I wish to have an e-mail client on my Linux Mint machine from which I can access my Outlook e-mails. To do so, I went to the 'Account Setup' page on Thunderbird and used these to set up my account: Your Full Name: <My Name> Email address: <email-id>@outlook.com Password: <My Microsoft password which I use to sign in to Outlook> Under Manual configuration: INCOMING SERVER Protocol: IMAP Hostname: outlook.office365.com Port: 993 Connection Security: SSL/TLS Authentication method: OAuth2 Username: <email-id>@outlook.com OUTGOING SERVER Hostname: smtp.office365.com Port: 587 Connection security: STARTTLS Authentication method: OAuth2 Username: <email-id>@outlook.com

I am sure that the password I am using is indeed the correct password. I still get an error as shown in the screenshot on the Account Setup tab. How do I resolve this issue? Thanks a lot!

I've appreciated using Thunderbird for an ad-free Hotmail experience for quite some time. I've changed my Hotmail password every few weeks lately and Thunderbird worked fine when I entered the new password at the prompt when Thunderbird started.

Just now however, I needed to get into my Microsoft account that uses the same password as my Hotmail account. My login to Microsoft failed. Trying to understand why, I looked in Thunderbird at the saved password for Hotmail's server:

oauth://login.microsoftonline.com (https://outlook.office.com/IMAP.AccessAsUser.All

https://outlook.office.com/POP.AccessAsUser.All 
https://outlook.office.com/SMTP.Send offline_access)

The saved password was a 464 character long ASCII string totally irrelevant to the password I'd selected for Hotmail and Microsoft.

I went through the password change process for Hotmail, was then able to get into my Microsoft account and restarted Thunderbird. As usual, Thunderbird asked for the new password. I entered it and was then able to receive new mail from the Hotmail server in Thunderbird. However, again, the saved password in Thunderbird for Hotmail was not the password I'd entered.

Next, I deleted the saved passwords in Thunderbird, restarted it and this time it prompted me to be sure I'd downloaded it from a reliable source. I've never seen that prompt before. It came with my Linux Mint installation, so I thought it would be safe, but again there's an irrelevant password saved for my Hotmail account.

It's like it eventually changes my password for Hotmail and Microsoft since I can get mail through Thunderbird with the odd password it saves, but if I use what should be my password for Hotmail or my Microsoft account via a web page interface, the password doesn't work.

I'll have to stop using Thunderbird if this continues.

When looking at my list of folders after download, the SPAM folder doesn't seem to update the count of unread messages until I specifically open it. I miss the fact I have spam unless I specifically go in and look. Is this a function/feature of JUST the SPAM folder (all other folders seem to have their counts updated after a download). On Thunderbird 115.12.1 64 bit if that is of interest.

I can receive from outrlook365 but cannot send....... my email shows up(lornea@fowc.ca)as a good account

the outgoing sever settings are correct: they are smtp.office365.com What can be the problem please

The latest update of Thunderbird somehow made this message appear "This is an unsupported version of Thunderbird!!" (see attached picture). Is this a bug? I've checked the version on the homepage and it's the same that's running on my PC (Windows 11).

I'm porting Thunderbird from my W-10 PC to a new Mac. I tried some things and found help on the net. Heere are the steps I took:

WHAT DOESN'T WORK (but I did): Removed installed Profiles folder and saved on desktop. Transferred PC Profiles folder to same place in Mac.

Deleted PC folder from Mac. Replaced Mac Profiles folder had previously moved. Deleted installs.ini and profiles.ini Started Thunderbird which created new profiles in Profiles folder.

WHAT SHOULD WORK BUT DIDN'T (after above): Removed new contents of Profiles folder. Transferred contents of PC Profiles folder to Profiles folder on Mac. Got the following message: "Your Thunderbird profile cannot be loaded. It may be missing or inaccessible."

What did I do wrong? Do I need to uninstall Thunderbird and reinstall? Would that solve problems?

Thank you.

Dear Sir/Madam,

I use the Thunderbird email client on my Microsoft Windows 10 desktop tower PC in order to access my Gmail account using POP3, using "only" my email address and password.

However, I note that Google plan to introduce more stringent and tighter sign in/authentication methods from September 2024 as follows:

https://support.google.com/a/answer/6260879?hl=en

Does Thunderbird have a workaround for Google's plans please?

Thanking you.
