Microsoft Graph PowerShell errors
Errors from the Microsoft.Graph PowerShell SDK — connection scopes, missing cmdlets, token failures, and bad object IDs. All fixes assume you're running an up-to-date Microsoft.Graph module.
The Microsoft Graph PowerShell SDK is the modern replacement for the AzureAD and MSOnline modules, and it inherits a thicket of new error messages. Most failures fall into one of three buckets: scopes (you didn't request the right permission when you ran Connect-MgGraph), object IDs (you passed a display name where a GUID was expected), or token state (your session expired, or you're authenticated to the wrong tenant). The pages in this category walk through each of those.
22 errors in this category.

Frequently asked questions
How do I know which scope a cmdlet needs?
Run `Find-MgGraphCommand -Command <cmdlet>` — it returns the required permissions for both delegated and application contexts. You can then call Connect-MgGraph with that scope.
Why does my script work for me but not other users?
You probably granted user consent the first time you ran it. Other users haven't been through the consent prompt. Have an admin grant tenant-wide consent so other users can run the same script.
Should I use Microsoft.Graph 1.x or 2.x?
Use 2.x for new work. It has better error messages, fewer breaking surprises, and is the version Microsoft actively invests in. The 1.x API surface is still supported but no longer receives major updates.
