Manage User Contacts in Microsoft 365 Using Graph PowerShell

User contacts play an important role in Microsoft 365—especially in Outlook-based workflows. Administrators often need to manage contacts during mailbox migrations, executive onboarding, cleanup operations, or automation-driven data consistency tasks.

With Microsoft Graph PowerShell, managing Microsoft 365 user contacts becomes predictable and scriptable. You can retrieve contacts, create new entries, update existing ones, and remove outdated contacts without relying on manual Outlook actions.

This article serves as a central hub for user contact management on M365Corner, linking to focused Graph PowerShell guides that walk through each operation in detail.
