Thunderbird Support Forum

I have seen some posts on this request but unsure if anything has been done to add/use if already there a feature to make an email account "inactive". I have several email accounts set up in Thunderbird but do not use them much but don't want to delete the account but don't want to have to have them active either. Any update on this issue is appreciated.

As of Sunday, Thunderbird can no longer reach my ATT server to download email. It has behaved for ten to fifteen years. Last time someone at ATT fixed it. I have been on the phone or on screen with ATT most of my waking hours since Sunday. (In the process I lost my internet, my landline, my cell connection, etc.) Everything is restored except the connection between Thunderbird and ATT. Everyone thinks changing my password will do it. Done it four times. It gets me into the ATT mail. I have replaced the password in Thunderbird settings with it to no avail. Is there anything you can think of? Not only is Thunderbird more attractive than ATT, I have thirty years of mail boxes there, a continuation from Eudora. I will appreciate your wisdom.

My calendar is Baïkal 0.8.0 running an a debian 10 server. My thunderbird is 115.12.0 (64-Bit) running on Ubuntu 22.04.4 LTS My other devices are two thunderbirds 115.12.0 (64-Bit) running on Ubuntu 22.04.4 LTS and aCalandar 2.8! running an Android 14

It does not matter on which client I add or change calendar entries then synchronize them (I can see on my Baikal dahboard, that the synchronization has succeeded!) the other thunderbird clients don't show the changes, even after explicite synchronization, only after unsubscribing and then new subscribing.

Please advice for help!

Thanks in advance

Please Someone help ?

I have followed all the suggestions I can find, but my Thunderbird Calendar will not sync with the Outlook Calendar on Windows 11. I am using TB Sync, but every time I try to add my Outlook Calendar ? It refuses to accept my Password, even though it is correct, and the User name and email are too ! It shows as error code 401, and cannot authenticate ?

I have tried a suggestion to create an 'App Password' to use in my Microsoft account, but the options described do not exist in my account !

Can anyone please help ?

I use Thunderbird 115.12.2 (64-bit) with Hotmail, using a local account on Windows 10. Microsoft is introducing 'modern authentication' on Hotmail, and I want to be ready for this, but I cannot follow the guidance at https://support.microsoft.com/en-gb/office/modern-authentication-methods-now-needed-to-continue-syncing-outlook-email-in-non-microsoft-email-apps-c5d65390-9676-4763-b41f-d7986499a90d

If I try to alter my existing Thunderbird Account Settings for my Hotmail account, the authentication method for Outgoing Server (SMTP) is shown as Normal Password but there is no option to change it to OAuth2. If I delete and recreate my Hotmail account in Thunderbird, I get an error message from Microsoft saying that I cannot log in because my browser is not set to allow cookies -- even though I believe I have set both Thunderbird and Firefox (my default browser) to allow cookies.

Updated from Windows 7 computer to a new HP running Windows 11, downloaded Mozilla thunderbird from my old computer I had used it successfully for years, & received all my In-box email but nothing was received in my Sent box. The Thunderbird application works as I sent myself an email and received same, but the entirety of my sent email history never arrived. What to do?

There's an article that says we can change where attachments are stored by going to tools, options, attachments. However, I have no "options" under "tools." Thanks in advance.

I'm using Thunderbird 115.10.1 and Windows 11 Pro. Thunderbird has suddenly started sending my partner's emails to Trash. We've been emailing fine for years before this. She has not changed anything in her emailing. I've closed and re-opened Thunderbird. Her emails are not marked as Spam and I have marked some of them as 'not junk'. Anyone got any ideas? I can't seem to find reference to other people having this problem.

Microsoft sent email last night announcing the end of "Normal Password" for Hotmail, and warning that Hotmail would REQUIRE "modern authrentication" beginning 9/16. I have personal desktop subscription to Microsoft 365. I have set Microsoft account to 2FA and checked in Tbird that cookies are enabled.

I have spent hours and days trying & failing. With server imap-mail.outlook.com using OAUTH2, Thunderbird won't sync and shows message saying that server doesn't support the authentication protocol please enter another one. With 2FA still turned on and using Normal Password setting and entering an App Password from Microsoft, the Imap connection is fine about 85% of the time, needing re-entry of the App password about once a day or so (usually requires several tries until App Password gets accepted.)

The 0AUTH2 fails with Norton Smart Firewall turned Off or Turned On-makes no difference.

(Sending email with Outlook and 0AUTH2 DOES work okay.)

I've also tried Imap connection with a different server: Outlook.office365.com, using 0AUTH2.

In this case, Tbird shows me a Timeout error and never makes an Imap connection to the server.  

I've been limping along with the app password, and "normal password" authentication, but now Microsoft announces they will stop accepting connections that are not 0Auth2 ("modern authentication") from Tbird or any other software after 9/16. The clock is ticking. I've tried every remedy I've seen online from Tbird or from Microsoft. Nothing has yet allowed a QAUTH connection for Tbird to a hotmail IMAP server. Please help! !

I can't SEND on Thunderbird as of Update to Version 115.12.1 on 6/19. I was able to SEND on June 18th and left town for a week and when I came back could not Send. That could be a coincidence. Have Windows 11, with Defender Firewall and Security virus protection. I have TB version 115.12.2 up to date. I have checked with Spectrum for the correct configuration and currently I have as Description: SMTP Server (on top line); Server Name: Mail.brighthouse.com and Port 465, No Authentication and SSL/TLS. My User Name: e-mail address ends in @tampabay.rr.com and that is the same as shown on incoming server.

My husband just downloaded TB program on his Windows 8.1 which is my old computer that I've been running TB on for 15 years without a hitch!! ''''And he also cannot SEND.'''' It's very frustrating - we've tried changing server settings since Spectrum uses not only Brighthouse (which is the one they say covers the Tampabay.rr.com address) but they also use Mobil.charter.net and also TWC.com. I've tried changing them up but nothing works. I've tried changing Ports and anything I could change I did, but nothing works. I did get a couple of error msgs but they didn't help. Brighthouse timed out and another msg was saying that the email address I was sending as had to match the email address of the authentication and that didn't make sense as I have only had one address & (typed correctly in all places). I have called Spectrum more than once and asked for an upper level, however, they were no help at all saying they have no resp. for 3rd party etc. I HOPE YOU CAN HELP SOLVE THIS MYSTERY. Thank you!

Dear Sir or Madam,

I have just migrated Thunderbird to my new CUBI desktop running Windows 11. I get security errors when I launch Thunderbird. My email provider The Messaging Company advised me to change server settings, which are now shown in the Troubleshooting Information page as account1 (pop3) pop.themessagingco.com.au:995 SSL/TLS Normal password smtp.themessagingco.com.au:587 STARTTLS Normal password true.

On launching Thunderbird I get the message Secure connection failed live.mozillamessaging.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate has expired. Error code: <a id="errorCode" title="SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE">SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE</a>

   This could be a problem with the server's configuration, or it could be someone trying to impersonate the server.
   If you have connected to this server successfully in the past, the error may be temporary, and you can try again later.

Or you can add an exception…

AND when I attempt to send an email I get warning that the SMTP server does not have a valid certificate. If I ask, in either case, to "Get Certificate" the response is that the site attempts to identify itself with invalid information.

I have "tried again later" over two weeks, and nothing has changed.

The Messaging Company is a fairly large email provider: it seems strange that its security is incomplete. However, I am not happy to just set an exception and over-ride these errors without doing all I can to check that there is not something screwy going on. I really value using Thunderbird, and The Messaging Company's advice that I should just use webmail is not at all satisfactory: I keep everything on my computer or backed up to a portable drive here.

Please: is there anything I can do or should know to fix this problem?

Best Regards, Margaret Mackisack

Greetings,

In Thunderbird 115.12.2 (64-bit) on Linux Debian 12.6, when I examine "Help -> About", cursor movement in the focused information window moves the list of messages displayed underneath in the unfocused messages window. Hopefully the image suggests the issue. Is this an OS problem or something that can be corrected in Thunderbird?

Also, I maintain several accounts, each with several folders. It would be helpful if these all stayed collapsed until selected, with a digit alongside indicating the number of unread messages in each, but recently they each seem to fully expand at inopportune times, making email management rather difficult.

Is this the result of a selectable setting somewhere, please?

When I start a email message search, I am bombarded with bad suggestions for email addresses. These include addresses from everyone I've received email from even though I have deleted these entries in collected email addresses and my personal address book.

The addresses could be from old purchases or ebay responses or anyone I've ever received an email from. I have deleted most of the emails entirely, yet I still get all these bad addresses when I search.

Is there a way to clear the history in search or remove the email addresses where I have deleted the email?

I've attached a Home Depot search as an example.

Since December last about every 30 days or so Outlook locks my account. This only happens when I "hit" send on an outgoing message from Thunderbird. A friend has suggested that Outlook sees my outgoing e-mails as spam and when it reaches a critical number Outlook locks my account. Attached is a screenshot of the error message. Has anyone else run into this problem and, if so, is there a solution? Thanks, Ken.

Hi, I’m trying to move from Outlook 2003 to Thunderbird 115.12.2 (64-bit). Using the import wizard fails. Tools > Import select Import From Outlook and the following message appears. “Either there is no default mail client or the current mail client can not fulfil the message request”. I’m taken back to the Import from screen with the addition of a red panel with “No Profile Found” on it. Outlook 2003 is the default e-mail client, checked more than once. I’m trying to migrate to thunderbird so I have no account setting, thinking they would be imported. My pst’s files have been moved to a directory on a different partition to the Outlook programme, tried creating a dummy profile using default Outlook storage and still fails. I’ve looked at converting pst files to mbox, but this doesn’t see to include the account settings. But I could add them manually or I can not import the mbox files or directory structure into Thunderbird. I’ve been messing around trying other things but nothing works. Internet searches, Thunderbird forum searches suggests solutions but all fails and the steps don’t match Thunderbird menu, etc in many cases. I’m stuck. Can anyone give any advice on how to migrate from Outlook 2003 to Thunderbird. Tools, Add-Ins or manual methods, anything just to get me up and running. PS I’ve two pst files, one is the default main Outlook.pst and the second a secondary store I created in the folders of Outlokk called Store.pst, beside the none default storage location everything else is standard for Outlook and Thunderbird.

Outlook.com and Microsoft inform me that in September 2024, Outlook 2007 will no longer work for email because it does not meet their spiffy new authentication thingy. They want me to quit using Windows 7, but I need it to run legacy productivity software for which there is nothing comparable. So, Windows 7 it is. I do have a dual boot system that includes Windows 10, but I don't want to mess with it for email if possible.

Microsoft suggested that Thunderbird would work, so I downloaded it. That's when everything went sideways. There is no utility to move my existing files and folders intact from Outlook 2007 to Thunderbird. I tried Thunderbird's Import but it refuses to cooperate. So, last chance for Thunderbird is contacting you.

Help me make a clean transition from Outlook 2007 to Thunderbird without losing contacts, folders and files.

My outgoing email stopped working suddenly. Incoming email works fine. I sent an email with a large attachment. It sent but after that I could not send anymore emails. I checked my password and server settings nothing has changed except I can't send email. I get a pop up window that asks for my password but after entering my password and hit enter I get another pop up window that says login failed please enter new password. The password works fine when I go AOL mail and enter it.

Hello --

Not sure when this happened.

Got 2 email accounts, account X and account Y. All was working fine until today, 6/27/24. Both have different outgoing SMTP servers.

Now I am trying to send, it is asking for passwords, which I have and is 100% correct. In fact, if I put in wrong password it tells me, so I know it is communicating. When I put in the correct password, I get a timeout on BOTH SMTP servers.

I disabled Norton Firewall.

Works fine from another PC app (poppeeper) and from my android (k9 mail). Both accounts are IMAP.

Neither SSL/TLS or STARTTLS makes a difference. Nor did a re-boot.

TB 115.12.2 (64 Bit) on Windows 10

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) mailroom4.hostrocket.com timed out. Try again.

Description: hostrocket Server Name: mailroom4.hostrocket.com Port: 465 User Name: ernie@e(redacted).com Authentication method: Normal password Connection Security: SSL/TLS

Anything change?
