On the left-hand navigation menu, click on 'Reports' and select 'Usage' from the dropdown list.

Looking for a cost-effective alternative to Microsoft Office?
While managing enterprise email requires specialized admin tools, your team's document creation needs can often be met without expensive Microsoft 365 licenses. WPS Office is a free, lightweight, and powerful alternative that offers full compatibility with Word, Excel, and PowerPoint formats.

Frequently Asked Questions
Can I see exactly when a user last accessed Outlook on the web?
Yes, the Email apps usage report in the Microsoft 365 Admin Center includes specific columns detailing the last activity date for various apps, including Outlook on the web.
Why is user data hidden or showing as anonymous in the usage report?
By default, Microsoft 365 conceals user, group, and site names in reports to protect privacy. A global administrator can change this setting in the Admin center under Settings > Org settings > Reports.
Can I schedule this Outlook app usage report to be sent automatically?
While the standard admin center doesn't natively email scheduled usage reports, administrators can use Microsoft Graph APIs or Power Automate to extract the usage data and automate report delivery.
