Get-AzADGroup -Select groupTypes returns non-standard GroupType property and hides groupTypes #28362
Description
Description
When running:
Get-AzADGroup -Select @("id", "displayName", "groupTypes")
The returned object does not expose the groupTypes property (plural), which is the correct property according to the Microsoft Graph API schema.
Instead, a property named GroupType (singular) is returned, which is undocumented and does not exist in Graph.
This is confusing because:
groupTypes is a valid Graph field (e.g., ["Unified"])
GroupType appears to be a synthetic alias or transformation
GroupType cannot be used in -Select because Graph does not recognize it
groupTypes is not accessible after the call because it is hidden or dropped
Expected behavior
The cmdlet should:
Either expose the actual groupTypes property (as per the Graph API)
Or clearly document that groupTypes is mapped to GroupType in PowerShell
Actual behavior
$g = Get-AzADGroup -Select @("id", "displayName", "groupTypes")
$g | Get-Member
Results:
No groupTypes property is visible
A GroupType property (non-standard) is present instead
This causes confusion and inconsistency with Graph documentation
Impact
This behavior causes confusion and breaks expected logic when:
Filtering or grouping by group type
Writing predictable scripts across API layers
Using Graph-native property names
It creates a gap between what is selected via Graph (groupTypes) and what is returned in PowerShell (GroupType) without explanation.
