Microsoft is adding a new Outlook for Windows usage data to its Microsoft Graph API

Organizations can now track how the new Outlook for Windows is being used within their company, thanks to a new usage Graph API that is coming to the 365 Admin Center and Grapth soon.

The new Outlook for Windows usage Graph API helps create detailed custom reports and analytics with metrics that will include the number of active users who have switched from classic Outlook to the new Outlook and indicators to show whether a user uses the new or classic Outlook over a specific period.

Microsoft announced in a recent entry to the 365 Roadmap, with a preview scheduled in March, followed by a general release in June of this year. The company states:

New Outlook for Windows usage will be added to the Microsoft Graph API, allowing organizations to monitor the adoption and usage of the new Outlook for Windows client within their organization. This will facilitate the creation of customized reports and analytics. Metrics included in the Graph API will match those available in new Outlook for Windows usage of Microsoft 365 apps usage report in the Microsoft 365 admin center, including tenant-level count of active users who have transitioned from Outlook for Windows (classic) to the new Outlook for Windows, as well as flags indicating usage of the new or classic Outlook per user over the specified time period.

The new report can be a method for organizations to see if the infrastructure is ready for the new Outlook or not. The new version of the platform has a lot of new and different capabilities than the older version, including faster AI capabilities (such as the ability to summarize email attachments, which is coming soon), better archiving formats, and more.

However, despite the new capabilities, users still prefer the older version,, and classic Outlook will be supported by Microsoft moving ahead.

On the other hand, this new capability means the Microsoft 365 Admin Center will become even more crowded with new features and areas. Just this week, Microsoft announced that admins won’t have to use PowerShell commands anymore, thanks to an enhancement coming to the platform soon.
