Thunderbird Support Forum

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 back up my TB profile every few months. I just went thru the Cox-Yahoo email conversion and I am getting emails. When I did my back up, I noticed in the properties it had one more folder and the files went from 1311 to 2585 files. Is something wrong? Do I need to compare and research what is causing this or just move on!

How do I include a newly made email account so that it will appear in unified folders? I thought that when the new email was added to Thunderbird it would automatically show in Unified Folders but it does not.

It must have been one of those nutty "...something I did" things that made a second account identity appear one day. I use a Unified Folders mode exclusively, and the subject account is my primary account (identical to the first Unified listing), but some action on my part made it pop up below as well, just above 'Local Folders.' The only subfolder under this redundant appearance is 'Templates,' which is empty. The unwanted appearance starts out in a blue font, but turns black (as shown below) once the 'Templates' folder is clicked on. Can I get rid of this somehow?

to select two or more messages on the message pane, one method is to hold down the CTRL key and left click on the messages you want to select. This has stopped working on my Thunderbird. When I select a message and then go on to select the next message, the first message I selected is deselected. So I can only select one message for an operation, e.g. "move", "delete", rather than a group of messages.

I composed an outgoing email message that I wanted to keep for future use, and saved it as a Template. That not only saved it under the unified Templates heading, but created a second appearance of my main email account with its own Templates subfolder. At that point I decided I really didn't want to keep it after all, so I deleted the message, but the second Templates folder didn't disappear; its still on the tree list as an empty folder. Right-clicking that folder doesn't have a Delete function, but it does present a Repair option, but running that doesn't help. How do I get rid of that unneeded individual email account listing and the empty Templates folder?

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 recently installed Thunderbird on my mac. It seems to work well, except that it will not show my Archive folder (simply named "Archive") in the list of folders. I can see from my mail provider's web app that it is there and has my messages in it, and if I use search in thunderbird I can find messages in the Archive folder, but the Archive folder is completely missing from the list of folders. (I can see other folders, just not Archive.)

I did find how I can customize what folders Thunderbird will put Archived messages in, but that's not what I'm looking for. What I want is to be able to see the already existing folder with messages archived by other clients, e.g. the provider's web app.

Hello, When sending a message from my gmail account within TB, I would like to automatically attach one of my other adresses as bcc: . How can I do that ?

As an alternative, is there a way to automatically copy the message in my sent folder in my gmail account to my local sent folder ? Using a filter perhaps , but I have been unable to create a filter that operates on the Sent folder.

Thank you, Alain Damlamian

I have a verizon.net email account at AOL. AOL now requires use of a one-time-use "app password" to sign in from Thunderbird. This does work but it seems like now I will have to go through this process (going to AOL web mail and requesting a new app password) every time I reboot my computer or restart Thunderbird. Is this true?

I have a notice in the bottom right of my Thunderbird screen stating 103mb of 110mb IMAP total (93%) has been used.

I presume there will be consequences should this reach 100%!

My mail server is showing no issues of quotas being reached.

Is this an issue that relates to Thunderbird quotas?

Can anyone advise how I can reduce the 103mb total that is being shown?

Many thanks in advance.

I have just altered my Hotmail settings in Thunderbird to take account of the Microsoft OAuth2 requirements. I can still send from Hotmail but cannot receive (download) incoming messages.

When I open Thunderbird, or check for email, I see the text "******@hotmail.com: Host contacted, sending login information......." at the bottom but no messages are downloaded, and eventually the text disappears (I know there are messages waiting as I can see them using the Outlook app)

My server settings are; Server type : POP Mail Server Server name: pop-mail.outlook.com Port: 995 User name: ******@hotmail.com Connection security: SSL/TLS Authentication method: OAuth2

I have tried restarting both my PC (Windows 10) and Thunderbird, but the problem persists. Help please!

I've been using Thunderbird for many years with no issues. I opened it today on my laptop and all my accounts, settings, emails, calendar items, etc. are gone. It's asking me to set up an account. I have years worth of saved emails from 4 different accounts and they are all gone. How can I get them back. I am using Windows 10.

I was getting warnings from my e-mail server that I was near the mailbox size limit, and Thunderbird displayed a percentage bar in the lower right corner. I've deleted a lot of large messages and want to see how far I am from the limit now, but now the bar isn't displayed. Is there a way to refresh this? Or is it a warning that's only pushed from the server?

(Unfortunately, my webmail site doesn't compute the size correctly and shows me at over 400%, so I can't see the actual size there until the server sends me another warning.)

I keep getting the attached error msg when trying to send an email. I've changed it to "Normal Password" as advised, but it's still the same. Any help would be appreciated. Regards norman

Thunderbird 115.12.0 inline image encoding does not work and neither Thunderbird nor any other email client can decode the images. I would not be concerned if the images were instead sent as attachments -- anything would be better than the situation right now. Here is what a the sent message looks like (truncated):

This is a multi-part message in MIME format.
