Why is it that Firefox can sync links and other setting across all versions, in all locations and yet Thunderbird can't even sync address books, history and filters? My only solution is to only run Thunderbird from a flash drive I have with me all of the time. It's not ideal but it works. Dave out

P.S. It also aggravates me that I have to use OWL with exchange server, which I dislike very strongly!

Something happened to my Thunderbird account on 6/15/24. I am not able to send or receive e-mails. I have attached 3 screen shots. One is showing at the bottom right of the screen that it times out and does not bring in any messages. Another shot shows settings for incoming and the other shot is showing settings for outgoing messages. Please help! I have tried to upload images of the screen shots taken and I get this error message. "Error uploading image

Invalid or no image received."

Thunderbird was not my default email app at POP3 installation, but anyway 900+ emails soon appeared in the Thunderbird inbox after my sign in for Outlook. My working assumption was that no emails would appear in an email app, unless that app was already the default app, which Thunderbird is not. The initial POP3 download is not under user control? Apparently not. But I don't think em-Client did this to me when testing it.

why does my hotmail in thunderbird sometimes get my emails and other times it says "Sending of password for user *********@hotmail.com did not succeed. Mail server pop-mail.outlook.com responded: Authentication failure: unknown user name or bad password"? Then it starts getting them again. It's totally random. Every once in a while it does it with my .live email too. Yet other .live and .hotmail addresses never have a problem? TIA

I have a brand new install of Thunderbird, and I want to import .mbox files that I converted from Outlook .pst files.

I have seen many support articles saying that to import .mbox files, I need to use the "Local Folders" option in the Folders menu on the left hand side of the main page. I have added the ImportExportTools NG plug-in, but I don't see a "Local Folders" option on my main page.

I must be missing a step. I have attached a screen shot.

Thank you for your help.

I am using Thunderbird version 115.12.2 on Windows 10 and have set up about 36 different calendars. To tidy up a bit, I would like to hide all calendars AT ONCE and in the next step show each (separate) calendar INDIVIDUALLY. ONLY: HOW do I hide all calendars at once? Possibly accessible via extensions / add-ons? Which extensions would be recommended? Thanks for all your help.

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.

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.

"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."

I have a custom domain (me@mydomain.com) with email / contacts / calendar hosted by Google Workspace. I initially managed to add both the email and calendar account to Thunderbird but recently the calendar stopped syncing.

I tried to fix the problem by first removing the calendar account. This did not work because the 'Create New Calendar' -> 'On the Network' account wizard does not prompt me for the Google OAuth2 login page but just asks me for a password and fails. I tried to supply several 'Location:' URLs like gmail.com, calendar/accounts.google.com but none lead to the Google OAuth2 page.

Finally I removed the email account too and re-added it. During the new account setup workflow Thunderbird seems to look for calendars too but failed to find any...

How do I proceed? How are you supposed to set up a Google Calendar on a custom domain using the OAuth2 sign-in procedure?

Issue began Monday 7/1 where Thunderbird would not receive new email from AOL. At times it would tell me to enter the password. But the p/w I entered was not correct so that made situation worse. Found "Saved Passwords" in Help->Settings where I was able to retrieve the -correct- p/w for one of the email addresses being actively used in Thunderbird and problem solved. When I went to find the correct p/w for the other email address, the account in "Saved Logins" was not there?? Was odd that the list did display email accounts I haven't used in years, but not the 2nd one that I use daily! I tried changing the p/w at AOL Mail, but that didn't work for either of my two accounts. Bottom line, why isn't lf82me@verizon.net showing up in the "Saved Passwords" in Settings?

Hello! Thunderbird has stopped downloading messages from my Yahoo+ account. I can send messages from it OK. When I try to get it to download, it says: Checking Inbox for new messages... and waits at this point. Then I get: Host Contacted, sending login information... Then it waits for a long time. Eventually, it indicates "No messages to download", and then goes back to "checking inbox for new messages". If I click "Get Messages", a pop-up comes up with: "Error with account... and below: The account fischer94563@yahoo.com is being processed. Please wait until processing is complete to get messages." I've deleted the APP and downloaded and installed a new copy. No changes. Deleted and reentered my password with Yahoo. I'm at a loss to understand why this is happening, but it was working fine until recently. Any thoughts? Thanks. Kevin

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.

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.

I changed the email server in settings and all my stored emails are gone! Win10, Tbird 115.10.1. How do I get them back? Only one Email acct of three are stored on the server and those get downloaded to a different computer and then removed from the server.

Background: I was wondering why I didn't get any new emails for a few days and apparently GoDaddy migrated servers without telling me. So the settings there were screwed up as a result of a "~" instead of a "-" in the server name which the tech support guy changed. I was eventually able to access emails at my GD acct using their webmail.

But the server name changed so new emails weren't downloading to my computer. I went into Tbird settings and changed the SMTP servers to the new server address and now I don't have ANY of the old emails which I neglected to backup. ALL I did was to change the server address.

Is there a way to change/view/merge the T-bird user folders so I can access the old emails, folder and directory? Thanks, Bob

Hello

I created an Archive directory within Local Folders, and within that have stored years of emails.

As of yesterday, when clicking on any given sub directory within the Archive, Thunderbird says that there are 0 messages to display.

All of the .sbd and .msf files are present when I browse the Archive structure in my user profile in Windows Explorer.

The problem seems to be that Thunderbird can read and display the directory structure, but cannot display the emails contained within it.

I do not have a backup of the profile directory (yes, I know!).

Can anyone offer a solution that will allow Thunderbird to display messages that seem still be present ?

With thanks in advance

I moved some emails to a folder from the inbox and now they are not displaying. when I search them I am able to find them and can be read, the search indicates that they are in "the new folder" all mail and important. This has happened before and I have not been able to resolve I am assuming there must be a setting I have activated/deactivated but I've no idea what. I am FAR from tech savvy so please give any answers in as simplistic form as possible. Thanks Matt

My send email button has dissapeared . I am unable to send any emails. Geek Squad has spent several hours trying to get my email send button back. They say there is a glitch in Thunderbird. Please fix it. My phone number is [edited phone# from public support forum]

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
