Microsoft Graph PowerShell Field Guide 2026: Authentication, Permissions and Production Patterns
Microsoft Graph PowerShell is the operational backbone of every Microsoft 365 script published on this site — but there is a gap between `Install-Module Microsoft.Graph` and a script that runs unattended in production at 6am every morning. Most admins lose a week falling into it. This field guide is the bridge: connection patterns, the permissions model that catches everyone the first time, app registrations for automation, throttling and paging that the lab hides from you, and the production patterns that keep a Graph script alive past the first 90 days.
