Windows Mail and Calendar are becoming Outlook
[MC650424 · Published Jul 20, 2023]: The Mail and Calendar apps for Windows are being replaced with the new Outlook for Windows. At the end of 2024 we will be ending support for the Mail and Calendar apps for Windows. The new Outlook for Windows helps people be more productive and in control of their inbox. Microsoft is excited about this change that will provide users with great new productivity features such as Microsoft Loop, message reminders, as well as file and people suggestions while composing an email. The new Outlook also offers more ways to stay in control with drag and drop emails as tasks, work hours and location, pinning and snoozing messages and many others.
How this will affect your organization:
For organization administrators the new Outlook for Windows will offer greater levels of control compared to Mail and Calendar such as the ability to (1) respect conditional access policies (2) enable/disable integration of features like Dropbox, Linkedin, Google Drive, ect. (3) enable/disable certain folders in Outlook and many more capabilities which can be found on the OWA Mailbox Policy Parameter page. Users within your tenant, who have accounts signed into the Mail and Calendar app, should already see a toggle in the application. Clicking that toggle will bring users to the new Outlook for Windows.

Over the coming weeks, Mail & Calendar app users will begin to see additional notices in those apps stating that support will end in 2024 and they will need to migrate to the new Outlook for Windows.
When this will happen:
Important: In late August of 2023, we will also begin a process of auto-migrating Mail & Calendar app users to the new Outlook for Windows with an option to go back if they choose. Users can go back to the current Mail and Calendar apps by clicking the toggle in the new Outlook for Windows.
What you need to do to prepare:
No action is required from tenant admins; however, you should reiterate the message to your users that Mail and Calendar will no longer be supported after the end of 2024.
We also want to reiterate that these changes will not affect your organization’s use of classic Outlook for Windows. Our guidance for Outlook for Windows users remains unchanged from our previous Message Center Post (MC381366)
If you would like to prevent users from adding their corporate email accounts to the new Outlook, you can follow the instructions in this document to disable the application for a single user, group of users, or the whole tenant:

Changes to the registration campaign feature in Microsoft Entra (previously Azure Active Directory)
[MC650420 · Published Jul 20, 2023]: Publicly switched telephone networks (PSTN) such as SMS and voice authentication are the weakest forms of MFA. To help your users move away from these less secure MFA methods we are introducing changes to the Microsoft managed state of the registration campaign (aka Nudge) feature in Microsoft Entra (previously Azure Active Directory).
When this will happen:
Starting September 2023
How this affects your organization:
Users in your organization who are relying on PSTN (SMS and/or voice) for MFA will be prompted to use the Microsoft Authenticator app. Users can skip this prompt for a maximum of 3 times, after which registration of the app will be required by default. Note: admins can decide it they want to opt out of the “limited” 3 snooze configuration or give their end users the ability to snooze indefinitely.
What you can do to prepare:
Microsoft urges you to motivate your users to immediately stop using SMS and voice for MFA. You can take advantage of several new admin levers to achieve this such as system-preferred MFA and Microsoft Authenticator Lite, in addition to registration campaign. However, if some of your users require more time you can exempt them for now. Sign in as Global Administrator or Authentication Policy Administrator and go to Microsoft Entra > Identity > Protection > Authentication methods > Registration campaign and exclude these user groups.

Bing Chat Enterprise rolling out in Preview starting today
[MC649341 · Published Jul 18, 2023]: Starting today, Bing Chat Enterprise will be rolling out to eligible Microsoft 365 tenants in Preview—it will be turned off by default.
To turn on Bing Chat Enterprise, you will need to use the link: https://aka.ms/TurnOnBCE. Bing Chat Enterprise gives your organization AI-powered chat for work with commercial data protection. With Bing Chat Enterprise, user and business data are protected and will not leak outside the organization. What goes in—and comes out—remains protected. Your organization’s chat data is not saved, Microsoft has no eyes-on access to it, and it is not used to train the models.

Learn more about Bing Chat Enterprise: https://aka.ms/BingChatEnterprise.
This change is associated with Microsoft 365 Roadmap ID: 151035
When this will happen:
Bing Chat Enterprise is off by default when it begins rolling out in Preview today.
It will be turned on by default in mid-August, however you can control whether Bing Chat Enterprise is turned on for your organization by following the instructions provided below.
How this will affect your organization:
If you turn on Bing Chat Enterprise, users will be able to access it, where supported:
- Bing.com/chat
- Microsoft Edge sidebar (requires Microsoft Edge version 114.0.1823.86 or higher in Stable or Dev channels)
Users must be signed in with their work account (Microsoft Entra ID, currently known as Azure Active Directory) to access Bing Chat Enterprise.
What you need to do to prepare:
To turn on Bing Chat Enterprise for your tenant:
- Use the link: https://aka.ms/TurnOnBCE
To turn off Bing Chat Enterprise for your tenant or opt-out of Bing Chat Enterprise prior to it turning on by default in mid-August:
- Use the link: https://aka.ms/TurnOffBCE
- If turned off, Bing Chat Enterprise will not be turned on by default in mid-August.
Note:
- As a temporary measure, organizations will need to have the Microsoft Search in Bing control enabled in the Microsoft 365 admin center to access to Bing Chat Enterprise: Set up Microsoft Search
- Total Solutions is working to bring the Bing Chat Enterprise controls into the Microsoft 365 admin center. We will provide a follow-up notification when they are available.
For further details, please see our technical documentation: Bing Chat Enterprise documentation. We recommend that once you turn on Bing Chat Enterprise for your organization, you inform your users of the new feature and have them sign into Bing.com/chat or the Microsoft Edge browser with their work account to access it.
Basic Authentication Retirement in Microsoft 365 Apps
[MC649046 · Published Jul 17, 2023] Microsoft 365 Apps are disabling server sign-in prompts using Basic authentication in Office Apps. We are making this change because basic authentication is a legacy authentication method that sends a username and password with each request. As a result, an attacker can access these credentials and use them to access resources. Continued use of Basic Authentication is a big security concern, so Microsoft has decided to deprecate it from all tenants.
Microsoft will retire this feature in Office Apps version 2307+. Instead, we recommend moving to a more secure authentication method, preferably Modern Authentication, and enabling multi-factor authentication based on OAuth2.0 token-based auth.
This retirement will not affect Exchange Online and Exchange on-premises. Customers using basic authentication to connect to Exchange on-premises/Exchange Online can continue to use basic authentication without any changes to Exchange.
There is a separate effort to retire Outlook connecting to Exchange Online using Basic Authentication. Please see Exchange Online – September 2022 Update.
Windows files share access is not affected. The underlying authentication layer for file share is NTLM, and there is not change to NTLM. More information is here – Microsoft SMB Protocol Authentication – Win32 apps | Microsoft Learn.
Access to files stored on SharePoint on-premises server that are using basic authentication will be blocked. However, files stored on SharePoint Online, OneDrive for Business are not affected. Customers who currently store files on web servers that use Basic authentication can move those files to SharePoint Online, OneDrive for Business, or SharePoint Server on-premises as a solution.
Note: This change is only impactful for organizations with on premises servers. If you do not have on premises servers, you can safely disregard this message.
When this will happen:
Microsoft will begin rolling this change to Current Channel in August 2023.
For additional channel timing please review: Basic authentication sign-in prompts are blocked by default in Microsoft 365 Apps
How this will affect your organization:
Once Basic authentication is disabled in your tenant, users with the Office Version 2307 or higher on their devices will not be able to access resources from servers using Basic authentication. After the upgrade, end-users will get a Blocking message. If a user tries to open a file stored on a server still using Basic Authentication, Office Client App will block the sign-in prompt and present this pop-up message to the user.

Note: Exchange Online team is working on retiring Basic Authentication separately, Outlook will continue to support Basic Authentication with Exchange Online till that work is complete. Access to all other resources using Basic Authentication will be blocked in Outlook Version 2209 and higher.

GA Rollout for Microsoft Edge management service in the Microsoft 365 admin center
[MC650423 · Published Jul 20, 2023] The Microsoft Edge management service, a new, dedicated and simplified management experience for Microsoft Edge in the Microsoft 365 admin center, is rolling out now for general availability. This tool allows IT admins to manage group policies and extensions with a simplified, intuitive UI. Admins can set policies through toggles and drop-down menus instead of the complexity of configuring JSON values, which helps reduce errors. This solution is another option for managing Edge that lives alongside Intune and other major endpoint solutions.
Global admins and Edge admins in the Microsoft 365 admin center can create and manage policies and extensions and assign these configurations to Azure AD groups using the intuitive UI. In the extensions tab, admins can access Edge Add-ons to search for, see ratings, add, and delete extensions, as well as view user extension requests, all in one easy-to-navigate location.
