Thunderbird Support Forum

I got an email from Microsoft saying my Live.com or Outlook.com email accounts won't be supported in Thunderbird UNLESS I change the settings to OAuth2 in incoming and outgoing server settings.

I even REMOVED the email account and re-added it making sure it was OAuth2.

But for my live.com & outlook.com email accounts I continually get prompts for passwords from Thunderbird. Sometimes I can't even click the RED X at the upper right to shut the prompt down. I just happens over and over until I give it what it wants.

I am tempted to shut down all Microsoft email accounts and switch to Gmail.

I have Thunderbird version 115.12.2 (64-bit) I used Windows 11 23H2 build 22631.3810 Windows Feature Experience Pack 1000.22700.1020.0

Any idea how to stop these prompts?

I like Thunderbird much more than any other email program I have ever used, and would like to keep it

Thank you in advance for any help. I am using Thunderbird 115.12.2

I'm on IMAP. I having a working knowledge of Thunderbird, but not a whiz by any means.

Since I have both personal and business emails, I keep them historically. I delete what I don't think I'll ever need to refer to.

When my email storage, gets into the 90's, I get nervous. I go through and delete as many emails as possible, and sometimes manage to get the percentage to go down 1 percent.

So... I'm a little confused. I thought that perhaps this was syncing with the Comcast server, and that the percentage was not for any Thunderbird storage. Is Thunderbird storing on another server?

What should my settings be, so that I can maintain all my email on my computer? I don't need to store it on any server. I'm afraid to make any adjustments for fear of losing email on my computer.

Is there someone who can walk me through this process in steps I can understand? LOL

I know I am set up with IMAP.

Thanks so much!

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?

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?

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!

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

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?

Thanks for the help with the screenshots David. Here are the 3 screenshots 1.) Error message on bottom right. 2 & 3) Incoming and outgoing server settings. Looking forward to solving this issue!

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."

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.

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
