Outlook says that it will no longer let third party mail apps like Thunderbird to access Outlook email as of September 16, 2024? What do you recommend?

"Action Needed – You may lose access to some of your third-party mail and calendar apps

Update your sign-in technology before September 16th, 2024 to maintain email access.

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 provided the solution in a related forum, but I can't locate it to link here. Basically, you have to delete your Outlook account while logged into Thunderbird (opt to keep messages), and the re-install it while in Thunderbird. Thunderbird will automatically find the new IMAP servers (outlook.office.365.com) and security settings (OAuth2) and populate your Outlook account. I didn't loose any of my emails, address book, or other settings. But see the caveats below.

I strongly recommend that you create local folders and drag critical emails to those folders before you uninstall / reinstall your Outlook account.

What I can't solve is that Outlook logs me in automatically and downloads all messages without prompting me for a password. No, I did not select "remember password" when I re-installed the Outlook account in Thunderbird.

Also, in Account Settings > Security, you have to allow cookies, which is probably why Outlook automatically downloads all my messages as soon as I click on the account within Thunderbird. I haven't been able to locate where Outlook is storing cookies on my computer.... yet.

This solution took me literally all summer - I kept trying to change the security authorization, IMAP (incoming server), etc., all to no joy.

As an aside, I am migrating to a paid Protonmail mail system, and once I'm done with the migration, I'm blowing Outlook off all my machines and mobile devices. I don't like ANYTHING that plants cookies on my devices.

Hi Benjamin, there is a support article about various security measures Microsoft has already rolled out. Are you using the method described here: Microsoft OAuth Authentication and Thunderbird in 2024.

*EDIT*

Microsoft has similar advice in the " If you use Mozilla Thunderbird" section of this page:

Thanks, read the article already, selected the preferred authentication method, now I cannot access or send any emails. There goes all access to business and personal emails. Thanks.

Do you get a sign-in prompt?

The article mentions:

  • Two factor authentication needs to be enabled on your Outlook account
  • You cannot block cookies for relevant Microsoft sites
  • Updating the Authentication method for both incoming and outgoing mail

I don't see any other requirements in the article.

Hi jscher2000 - I just tried to follow the directions given. I was able to switch the Authentication Method to OAuth2 under "Server Settings", but I was *not* given that option when I tried to do the same thing for "Outgoing Server (SMTP) Settings". I was only given the following options: • No authentication • Normal password (which is what it has been set to) • Encrypted password • Kerberos/GSSAPI • NTLM

I am using Thunderbird 115.11.1 on a 2022 MacBook Air running MacOS Monterrey. Why isn't the OAuth2 option listed?

Do you have smtp.office365.com for the server, not something like smtp-mail.outlook.com? Also, the incoming server should be outlook.office365.com. If you don't have the right server, change it, restart TB, and see if OAuth2 appears in the drop-down.

After that did not work, I tried option 2 - delete the account from TB and re-add it. It's working fine that way. It "knew" how to configure everything.

Thanks for the help!

Martymoz: When you deleted and re-installed, you deleted the "Account" from TB and then re-installed it? You didn't delete and re-install TB itself? Were you able to access your Address Book and Local Folders intact after the re-install? More detail please.... I have a huge Address Book and almost 100 Local Folders I can't lose!

Benjamin Good questions. Unfortunately I did not check that. It took over an hour to download and index the messages. I can check for you tomorrow.

I checked. The address book seems to be shared with a Yahoo email account that I access with TB as well. So my address book is intact but I can't really say why.

If I recall correctly, when I told TB to delete the Outlook account, it asked me if I wanted to delete all the local data and I said no. So once again I don't know if that is why my newly added account appears intact.

I did not delete TB. I left my Yahoo account alone and only deleted and re-added the Outlook account.

It seems we use TB a little differently. Maybe you can backup/copy/save your local folders and address book before deleting. Also, you may want to wait a while. You do have a few months. Maybe TB support will address this issue better and it will be a seamless transition.

Good luck.

Hello anyone, I have received that Microsoft email also last week, and another one today, I thought it was a Spam but came here and saw someone has/had that same email. I read the people's Message for Help here and I do not understand at all what to do. I just did a new Update of my Mozilla Thunderbird and I do not know what I should do next. Is there anything I should do more to keep my Hotmail/Microsoft E-mail on? Thank you for your time and efforts, very appreciated here.

Thank you Benjamin,

I removed/un-installed Hotmail from Mozilla Thunderbird, re-installed and got a yellow line saying that Thunderbird did not accept hotmail, something to this effect. I closed Thunderbird and re-opened it and I got a pop up low right side that Thunderbird ESR Thunderbird failed to connect server .hotmail.com

I send myself an email at hotmail, I received it at Microsoft's Hotmail but not in Thunderbird. I changed the setting Outgoing Server to Use default server, it did not work.

The SMTP Server shows: Description: Outlook.com(Microsoft) Server Name: smtp-mail.outlook.com Port: 587 Default:587 Connection security: STARTTLS Authentication method: Normal password User Name: is my hotmail email address

I do not know what to do next, please can you help me. Thank you for your time and efforts.

Update Benjamin,

I just removed and reinstalled Hotmail and now it is working, no glitch at all this time. I just unchecked "Remember Password" and it came in no problem. I'm all set now.

Thank you for your time helping me earlier.
