M365 Roundup, March 2024: Copilot for Security Gets a Launch Date
TL;DR
- Microsoft Copilot for Security reaches general availability on April 1, 2024 with pay-as-you-go pricing and new Entra identity skills.
- Beginning in Q2 of calendar year 2024, CSP partners can transfer NCE subscriptions from one partner to another mid-term, a long-requested flexibility change.
- Restricted SharePoint Search, rolling out from early April 2024, lets organizations limit Copilot and Enterprise Search to a curated set of SharePoint sites during rollout.
- Copilot for Microsoft 365 eligibility expands to Microsoft 365 F1/F3, Business Basic, Office 365 E1, and more in the coming weeks as of March 2024.

March 2024 is the month Microsoft put a date on AI for the SOC: Copilot for Security goes generally available April 1 with pay-as-you-go pricing, and Entra, Intune, and Purview all picked up Copilot hooks to match. The partner story is just as big, with NCE subscriptions finally becoming transferable mid-term starting in Q2. Add Restricted SharePoint Search for taming Copilot oversharing, a default flip on web grounding, and a Teams release wave headlined by voice isolation, and there is plenty to act on. Grouped by product, with rollout dates throughout.

User Risk Investigation, a skill embedded in Microsoft Entra itself, enters public preview. The skills give identity admins context and insights for security incidents and help resolve identity-related risks and sign-in issues.

Restricted SharePoint Search: the Copilot oversharing valve
Rolling out from early April 2024, Restricted SharePoint Search lets you disable organization-wide search and restrict both Enterprise Search and Copilot experiences to a curated set of SharePoint sites of your choice. Either way, users can still interact with their own files and previously accessed content in Copilot for Microsoft 365. For tenants where permissions cleanup is unfinished, this is the practical bridge to a Copilot rollout. Full announcement: Introducing Restricted SharePoint Search (opens in new tab). Completion expected by late June 2024.

Web content grounding flips to on by default
Beginning late March 2024, the Web Content toggle for Copilot for Microsoft 365's Graph-grounded chat changes its default from off to on. Users see a one-time in-app banner about the change with a link to switch it back, can check the toggle in the plugin menu of the chat box, and can flip it per-prompt to scope how Copilot grounds each response.
GPT-4 Turbo comes to the work scope
Copilot's Graph-grounded chat, the "work" scope reached via copilot.microsoft.com, Bing, the Copilot Teams app, and microsoft365.com, is being upgraded to GPT-4 Turbo for faster and more comprehensive responses. The rollout is in progress and expected to complete in the coming weeks as of March 2024.
Enterprise and web grounding in Word, Excel, PowerPoint, and OneNote
Enterprise graph grounding becomes the default for all requests, combining file context (document, spreadsheet, page) with enterprise content. Searches behave like Microsoft 365 Chat: the same policies apply, excluded sites stay excluded, and users only get results for what they can access. Web grounding is included in all requests, governed by the Connected Services setting. Rollout: early April 2024, starting with Word on Windows and Online, then PowerPoint, Excel, and OneNote across platforms, completing by September 2024.
Purview logs which files Copilot touched in meetings
The AccessedResources field will populate in Microsoft Purview for meeting Copilot interactions, referencing the files Copilot used from services like OneDrive and SharePoint Online to answer a user's request. Useful audit detail for anyone governing AI data access.

Multi-turn conversations in Teams chat and channels
Copilot in Teams chat and channels gains follow-up questions: it answers conversationally using the context of the past two questions and responses over a 24-hour period, on desktop, web, and mobile. Rollout: early April 2024 (previously late February), completing by late April 2024 (previously early March).

Citations for Copilot responses in Teams mobile meetings
Each Copilot response in Teams mobile meetings and calls gets a citation number. Selecting it reveals the content source; when that source is the transcript, a viewer opens showing the exact quote, the speaker's name, and the timestamp. Rollout: mid-April 2024, completing by early May 2024.

Nudging non-users: the Copilot popover message
In the Microsoft 365 admin center's Copilot usage report, a new action card configures a templatized organizational message. Once set, users who have not used Copilot for Microsoft 365 in the last 30 days see a popover in Teams recommending they try Copilot. Rollout: late March 2024, completing by mid-April 2024.

Adoption Score adds an AI assistance category
A new people experiences category in Adoption Score tracks Microsoft Copilot adoption on a 100-point scale. It ships in preview and does not affect the overall Adoption Score. Rollout: late June 2024 (previously early March), completing by late July 2024 (previously early April).

Copilot in Forms
Users with Copilot for Microsoft 365 licenses can describe the form they need in natural language, get a generated form, preview and refine it, and apply suggested themes to lift engagement. Rollout: late February 2024, completing by early March 2024.

Partner and admin: the NCE transfer change is the big one
NCE subscriptions become transferable mid-term
Beginning in Q2 of calendar year 2024, CSP direct bill and indirect providers can transfer CSP new commerce (NCE) subscriptions from one partner to another, including mid-term, based on partner feedback. One caveat: receiving partners do not get the seven-day cancellation option for midterm transfers. For any MSP that has won a client locked into another partner's NCE terms, this is the change worth celebrating this month. Full announcement (opens in new tab)
Lighthouse roadmap, including user offboarding automation
Microsoft published recent and upcoming Lighthouse updates, including user offboarding automation: Microsoft 365 Lighthouse vision and upcoming features (opens in new tab)

Purview audit search via Microsoft Graph API
A new Audit Log Query API in Microsoft Graph lets admins programmatically access Purview audit logs. Rollout: mid-March 2024, completing by late March 2024. To use it, register your application with Microsoft Graph and add the relevant permissions.

Automatic feedback on user phishing submissions
Defender for Office 365 can now automatically respond to end-user phish submissions based on the verdict from the automated investigation and response (AIR) investigation.

Status: generally available. More info: Automatic user notifications for user reported phishing results in AIR (opens in new tab)

Status: generally available. More information: Insider Risk in Conditional Access (opens in new tab)


Teams: voice isolation leads a practical batch
Voice isolation reaches GA

Learn more: voice isolation in Teams (opens in new tab)

Intelligent call recap for Teams Premium and Copilot users
The Calls app gains AI-generated notes and action items for both VoIP and PSTN calls, with summaries generated from calls where transcription was enabled. Available in the first half of 2024 for Teams Premium and Copilot for Microsoft 365 users.

The Queues app (Teams Premium)
A collaborative call handling solution: team members pick incoming PSTN and VoIP calls from the queue, make outgoing calls on behalf of call queues or auto attendants, and watch their queue performance. Authorized users, with permissions from Teams admins, monitor call queues and auto attendants in real time, opt team members in or out, generate performance reports, configure queues and auto attendants, and update greetings and other delegated admin functions. The app pins to the left side of the Teams client and requires a Teams Premium license. Rollout: late March 2024. Learn more: the Queues app (opens in new tab)

Outlook: location-aware calendars and thread forwarding
Working hours and location improvements
Building on 2023's flexible working hours, which let users set different hours and an office or remote location per workday, update them in the calendar, and see coworkers' locations in the scheduling assistant, two additions are rolling out: an updated daily location menu for planning the day and seeing who else is in the office, and integration of work location with Out of Office time.

Loop: guest sharing arrives, governed by your sharing settings
