IF I SEND AN EMAIL TO MYSELF, JUST ONE WORD AS A TEST, I HIT "SEND", AND IT IMMEDIATELY GOES AND ARRIVES, AS PER NORMAL. FINE. IF I SEND EXACTLY THE SAME ONE WORD EMAIL TEST TO, FOR EXAMPLE, MY WIFE, OR ANY OTHER INDIVIDUAL RECIEPIENT, IT TAKES A LONG TIME TO EVEN SEND. I GET A PROGRESS BAR AS IF I WAS SENDING A LARGE RAW FILE OR SOMESUCH. LIKEWISE IF I SEND THE EMAIL TO ME AND CC IT TO ONE OTHER PERSON IT TAKES AGES TO SEND. ONLY AN EMAIL TO MYSSELF ALONE WORKS AT THE USUAL SPEED. MY BROADBAND SPEED IS FINE. I HAVE USED THUNDERBIRD FOR YEARS ON DIFFERENT LAPTOPS AND DIFFERENT COMPUTERS WITHOUT THIS ISSUE. I DO NOT KNOW WHAT TO DO, CAN YOU HELP?

I wish to access my emails through Thunderbird (in addition to Zimbra) . On a previous computer I had both providers working side by side without difficulty. However my attempted download of Thunderbird is thwarted by the message "you are about to override how Thunderbird identifies with this site. Legitimate banks, stores and other sites will not ask you to do this".

My further investigations online suggest I should "check where my email is posted (My broadband connection is with Shell Energy) and if in the same domain as the mail server, create the security exception".

I am not sufficiently computer literate to understand all this and Shell Energy say they cannot advise me. I do not wish to lose my existing email access via Zimbra and wish to continue using my email address. Would creating the security exception solve the problem and enable me to get both email services together?

With thanks, Patrick Palmer

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.

In Thunderbird, I would like to use Cards View, and sort each folder in my email account according to desired 'Sort by' settings (namely, sort by date in descending order and use the 'unthreaded' option).

I cannot locate a setting or an option to apply the desired sort settings to all folders in my account. Rather, it appears I must manually apply these settings to each folder, which is tedious given I have a large number of sub-folders in my inbox folder.

Is there a way to apply the settings for one folder to all others, or to change the default settings for each (existing) folder?

AOL emails won't download to TB. POP. Spent hour and a half with AOL help, reset password, checked everything, got recent emails downloaded, but still can't connect for new mail. 'Server Error" " Log-in Failed" etc. Sending mail no problem. They say TB issue. Sudden stop 6/21/24. Mozilla help site directs me to find things on PC that I can't locate or understand. Not very tech-savvy, pretty frustrated.

I've been using Thunderbird for my hotmail.com and cox.net accounts for many years. Recently cox transitioned to yahoo.com with their email and users had to transition over. I was able to do this for 5 accounts - no problem. My hotmail.com was a bit more of a challenge but I was able to get it to work. Last week I started getting sign-in errors. Nothing worked and I deleted my hotmail.com address in Thunderbird figuring it would be better to just start over - wrong choice. Now I cannot even install my hotmail.com account on my Thunderbird.

I first tried the straightforward approach. Get an app password from my Microsoft account. Nest I it account actions, add email account. I added my name, email address and app password. When I hit ok a message quickly flashed saying configuration doesn't work. When I done I get a message that server already exists. I tried going to manual configuration and changed to normal password but got the message again that server exists. I went to the Outgoing server (SMTP) list but the outlook server doesn't show up.I tried using the hotmail password instead og the app password with same results. Finally I logged out of Thunderbird, turned off the two party requirement in Outlook and again tried to add the account to Thunderbird. Now I get the message 'could not get issuer fot oauth2 authentication'. I next went into manual configuration, turned authentication to 'normal password' the the hotmail account installed.

I closed Thunderbird and started again. sent a message to the hotmail account and had to reenter the password - works. Tried to send a message and was asked againgn for the app password - then it works. So all is good except when I check the server settings for smtp and IMAP, ot shows 'normal password' After strugglig for two hours I do not want to risk changing them to oauth2. Checked under 'saved logins' and the app password is shown. Is it likely that I have arrived at a stable solution? What am I risking by having the 'normal password' authentication?

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.

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'm trying to migrate from Fairpoint to Breezeline as my provider. I need two email accounts, one for work and one for personal. I got a new work account "sort of" working. I can send and receive email with it, but it doesn't react when I click on "Get messages." The second account I can't get to work at all. I copied the same server settings I used for the first account, obtained from the Breezeline website. They are:

Username: Name@breezeline.net

Incoming mail server: mail.breezeline.net IMAP port 993 Security type SSL

Outgoing mail server: mail.breezeline.net Port #465 Security type SSL

Authentication method: Normal password

I used the same password for both accounts.

When I tried to get messages or send on the second account, the message is "Login to server mail.breezeline.net failed."

I checked the Breezeline webmail site. It recognizes Account 1 but "cannot find" Account 2. According to the Breezeline website, I can have more than one account.

Please help! THANK YOU!

When I am trying to access emails, a popup says to get certificate= imap.aussiebroadband.com.au:993 and confirm security exception. It will not allow emails to download

How can I stop Google constantly interfering with my usage of other programs. It wants me to sign -in with my gmail a/c. Not interested. Only just happened. Have been using Thunderbird (and Firefox) without any problems for many years. I feel Google is trying stand-over tactics.

I have a new windows 10 machine and have a new install of Thunderbird. Hosting email server has 2966 emails that I would like to recover. Started process of downloading them and got to 1895 when it failed with the error message "Unable to write email to mailbox" Check the settings. Tried removing the account and recreating it. Removed the 1895 emails that I have downloaded and got the same result. It seems to be broken some where between Thunderbird and the hosting mailserver as I can login via webmail and see and read the balance of 1071 emails. Techs at the hosting server company have no idea what could be causing the problem. Any help would be appreciated. Regards, Richard

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.

Hi I have just installed thunderbird and I have 2 email accounts. In both of the accounts I can't find the "sent" folder. Thunderbird is showing only the inbox folder and the trash folder.

Can you help pls?

Hi, I am hoping to have two thunderbird downloads/accounts on the same computer.

ie can I run 2 separate thunderbird portals -

one for my talktalk emails

and a completely separate one for my gmail/google accounts.

I know I would be able to load the gmail/google onto my original Thunderbird account (but I would like to keep them completely unconnected)

Thanks in anticipation, HM

Is there a way to remove the "read" message bar at the top of the mail. It shows all the messages you have read, so I don't have to keep deleting them. I've looked all over and can't find anything about it. TIA Linda

Since my husbands departure, I have had the hardest time trying to access my husbands accounts. Luckily we have recovered many, but one of the most important ones is his thunderbird account. He is due to receive important information that I as his wife am unable to access. Can someone please point me in the right direction. I can be reached at [edited @gmail.com ] Thank you for your time, Chun Walls

I've managed to migrate emails from Outlook 2007 to Thunderbird 115.12.2 (64-bit). Everything was going great until I marked the messages as read. Now, I can't see the messages. I don't want that. I want to be able to archive my emails in folders -- I have the disk space to do so. How do I get my emails to appear (Thunderbird shows email counts, just can't see the messages), and fix it so that I don't lose them again?

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
