(Updated) Smart Calendar available in Classic Outlook for Microsoft 365 Copilot users
Message ID: MC1181279 (Updated)
Updated July 21, 2026: After evaluating customer feedback and our product direction, we have decided not to proceed with a general availability or worldwide release of Smart Calendar. The Smart Calendar Private Preview will therefore be retired. Copilot capabilities in calendar will be delivered natively in the Classic Outlook (Win32) calendar for Microsoft 365 Copilot-licensed users, so a separate Smart Calendar experience is no longer needed. More details are shared below.
[Introduction]
Note: You’re receiving this message because your organization is part of our Smart Calendar early access (Private Preview) program.
This update introduces several key benefits:
Smart Calendar was offered in Private Preview as a Copilot-powered calendar experience inside Classic Outlook. After hearing from our customers we have decided to bring Copilot calendar capabilities directly into the native Classic Outlook calendar for Microsoft 365 Copilot-licensed users rather than delivering them through a separate Smart Calendar experience. As a result, the Smart Calendar Private Preview will be retired and will not expand to general availability.
Why we are making this change:
- Our direction is to invest in Classic Outlook (Win32) as a first-class platform and deliver Copilot value natively to all Copilot-licensed users.
- Delivering these capabilities in the native calendar reaches the same users without a separate experience, and keeps management simpler for IT.
The key Copilot capabilities will be delivered natively in the Classic Outlook calendar in the coming months making it easy for Classic Outlook users to get value from Copilot seamlessly.
[When this will happen:]
- Private Preview access end data: Access to Smart Calendar will stop on 28th August 2026.
[How this affects your organization:]
Who is affected:
- Tenants enrolled in the Smart Calendar Private Preview.
- Users with Microsoft 365 Copilot licenses in Classic Outlook (Win32) who tried Smart Calendar.
What will happen:
- The Try the Smart Calendar app banner will be removed from Classic Outlook
- Smart Calendar app will be removed from Classic Outlook.
Your classic calendar is unaffected. Because Smart Calendar coexisted alongside it, there is nothing to migrate and no data is removed.
[What you can do to prepare:]
- No admin action is required.
- Let any users who tried Smart Calendar know the Private Preview is ending and that Copilot calendar capabilities will come to Classic Outlook calendar in coming months.
- Update any internal documentation that references Smart Calendar.
[Compliance considerations:]
| Compliance Area | Explanation |
| AI/ML capabilities interacting with customer data | No change in data handling. Smart Calendar is being removed. Copilot calendar capabilities in the native calendar continue to operate within Microsoft 365’s existing security, compliance, and data protection boundaries. |
| Admin control available | Admins continue to manage Copilot licensing and access through the Microsoft 365 admin center and Entra ID group membership. |
| User control available | No action needed. After removal, users continue with the classic calendar. |
