| MC1143276 | (Updated) Microsoft Viva Engage: Smarter delivery of Community Announcement notifications | Previously, when an admin created a new Community Announcement, this would send a notification in Teams and Mobile Push immediately, followed by an email notification two hours later if the announcement was not opened already in Teams and/or Mobile Push. With this new update: Users will now receive the notification in one channel only-either Teams, Mobile Push, or Email. This notification channel may differ by user and is selected based on where a user has opened Engage notifications most frequently in the past 30 days. If the announcement is not opened within two hours in the first notification channel, a secondary notification channel will be sent, also determined by where a user opens Engage notifications most frequently. We will continue to respect all user notification preferences and settings where applicable. If a notification channel is disabled or the app is not installed, it will not be selected as a potential notification channel for the Community Announcement delivery. Note that this change applies only to regular Community Announcements in Viva Engage and does not affect the "immediate" Community Announcement feature (where admins can still select the checkbox to send emails immediately -this functionality remains unchanged). Can I still notify Community users via email immediately (along with other notification channels)? Yes! In Viva Engage, we offer an option to send an "immediate" Community Announcement. With this feature, Community admins can choose to send email notifications immediately after posting a Community Announcement, even if a user has opted out of receiving emails. All other notification channels will also send immediately along with email, including Teams and Mobile Push. Therefore, we recommend admins to use this feature when there is a Community Announcement that requires immediate attention from users. Community Admins can find this "immediate" Community Announcement option by firstly navigating to the announcement publisher and selecting the hyperlinked "option to send emails immediately" at the bottom of the publisher. Upon clicking this option, an additional pop-up box will open called "Immediate email delivery". By selecting this checkbox, this will ensure that all three notification channels - Email, Teams, and Mobile Push - will send to customers immediately after a Community Announcement is made. What you can do to prepare No admin action is required. However, we recommend: Informing your users about the new notifications change to reduce confusion Monitoring user feedback and engagement with Community Announcements' notifications delivery Reviewing internal communication strategies to align with the new notification's behavior Compliance AreaExplanation Does the change alter how existing customer data is processed, stored, or accessed?Yes. Notification delivery logic now uses user behavior data (last 30 days of notification engagement) to determine delivery channels. This data is used to personalize delivery but is not stored permanently. Does the change introduce or significantly modify AI/ML or agent capabilities that interact with or provide access to customer data?Yes. The system uses behavioral data to determine the most effective notification channel, which is a form of machine learning-based personalization. Does the change provide a new way of communicating between users, tenants, or subscriptions?Yes. The change modifies how users receive communications (Community Announcements) by introducing a dynamic, behavior-based delivery method. |

| MC1182535 | (Updated) Retirement of Visio Data Visualizer Add-in for Microsoft Excel | Who is affected: All Microsoft 365 users who use the Visio Data Visualizer add-in in Excel, and admins managing centralized deployment of Office add-ins. What will happen: Starting December 8, 2025, the add-in will be removed from the Excel add-in store, templates, and ribbon. Users will no longer be able to create new Data Visualizer diagrams using the add-in. By March 2, 2026, the service powering the add-in will be shut down. Existing Data Visualizer add-in diagrams embedded in Excel will no longer load or refresh after this date, though the underlying Excel table data will remain intact. In November, users will start seeing a business bar in the Data Visualizer add-in frame notifying them of the upcoming retirement. The business bar will include a link to a detailed, user-facing article explaining how to save their diagrams as Visio (.vsdx) files. What you can do to prepare: If your tenant does not use centralized deployment of add-ins, no action is required. The change will be applied automatically on the specified dates. If your tenant uses centralized deployment of add-ins in the Microsoft 365 admin center: Turn off the Data Visualizer add-in by December 8, 2025. After the service shuts down on March 2, 2026, delete the add-in. Learn more: Manage add-ins in the Microsoft 365 admin center Inform your users about this change and its timelines. Encourage users to save any existing Data Visualizer diagrams as Visio (.vsdx) files before March 2, 2026. After that date, diagrams embedded in Excel will no longer be accessible or refreshable. Update any relevant user documentation to reflect that the add-in will no longer be available after December 8, 2025 and that the service will be fully decommissioned on March 2, 2026. Share information about alternate options, such as Visio Plan 2 and creating data-backed diagrams via the Visio desktop app. Steps for users (Microsoft 365 subscribers): Open the Excel file containing the Data Visualizer diagram. In the diagram area, select the More options menu (…) and choose Open in web. If prompted, sign in with a Microsoft 365 work or school account. A Visio (.vsdx) file corresponding to the diagram will be created and saved to OneDrive or Visio for the web. After March 2, 2026, the data connection and refresh features will no longer function, but the saved Visio file will remain accessible.

| MC1190199 | Flexible layout for Teams meetings with resizable divider | [Introduction] We're introducing a new flexible layout option in future Teams meetings to give users more control over how shared content and participant videos appear. A resizable divider will let users adjust the space between shared content and the video gallery. Want to focus more on the presentation? Expand the content area. Prefer to see more people? Shrink the content area to make room for more video tiles. Users can also swap the position of content and participants to suit their viewing preference. This works with spotlighted speakers, pinned videos, and Speaker View, providing a more personalized meeting experience-especially helpful on larger or ultra-wide screens. Screenshot 1: When someone is sharing content or when you are in Speaker view, grab the divider between the left and right views to resize them. Screenshot 2. When you drag the divider to the left, you will see more people in the right gallery view. When you drag the divider to the right, you will see less people in the gallery but the content or speaker will become larger. This message is associated with Microsoft 365 Roadmap ID 528930 and applies to Teams for Windows desktop and Teams for Mac desktop. |
