Microsoft 365

Discover users, track license assignments, and monitor sign-in activity across your Microsoft 365 tenant

Microsoft 365 is Microsoft's cloud-based productivity suite, encompassing Office apps, Exchange, Teams, SharePoint, and more. Connecting Microsoft 365 to Harmony gives IT teams full visibility into user accounts, license assignments, and sign-in activity - making it easy to manage access, optimize license spend, and stay on top of account hygiene.

This integration is read-only. Harmony pulls data from Microsoft 365 but does not make changes to your tenant.
