We request the following permissions:Īfter doing this, you may return to using the version you were using previously.ĮDIT: Per Microsoft documentation, administrators should be able to visit /adminconsent?client_id=9e5f94bc-e8a4-4e73-b8be-63364c29d753 in order to authorize Thunderbird.

If you encounter a screen saying “Need admin approval” during the login process, please contact your IT administrators to approve the client ID 9e5f94bc-e8a4-4e73-b8be-63364c29d753 for Mozilla Thunderbird (may appear to admins as “Mzla Technologies Corporation”). If you are using a hosted Microsoft account, please temporarily launch Thunderbird 107.0b3 or later ( download here) and attempt to log in, making sure to select “OAuth2” as your authentication method. We have already made the necessary changes in the current Thunderbird beta series. However, if your email server is Exchange, Office 365, or, Outlook should be your default choice due to the Cached Exchange Mode and Microsoft apps and services integration. However, some of these accounts are configured to require administrators to approve any applications accessing email. Mozilla Thunderbird is a free email client, which makes it a preferred choice as it supports all email servers and allows to configure multiple accounts. In the Email apps section, click Manage email apps. Select the user, in the properties of the user panel click Mail. In order to meet Microsoft’s requirements for publisher verification, it is necessary for us to switch to a new Azure application and application ID. Open the Microsoft 365 Admin Center (web page) and go to Users > Active users. In a coming release of the Thunderbird 102.x series, we will be making some changes to the way we handle OAuth2 authorization with Microsoft accounts, and this may involve some extra work for users currently using Microsoft-hosted accounts through their employer or educational institution.
