Get-RubrikM365SizingInfo.ps1 fails if you have multiple groups with same displayname.

Get-RubrikM365SizingInfo.ps1, line 311.

$AzureAdGroupDetails = Get-MgGroup -Filter "DisplayName eq '$AzureAdGroupName'"

Filter uses DisplayName. Which is not a uniqe property. script fails if you have multiple groups with same displayname, typically security and distribution groups with same displayname.

Changing to GUID or adding something that handles multple groups solves it.

To make it work in my case where it has multiple groups with the same displayname, I just picked the first one. Should work regardless of result size.

$AzureAdGroupDetails = Get-MgGroup -Filter "DisplayName eq '$AzureAdGroupName'" | Select-Object -First 1

alternatively

if ($AzureAdGroupDetails.Count -gt 1) { 
# Some message here about multiple groups. and selecting the first 1
 $AzureAdGroupDetails = $AzureAdGroupDetails | Select-Object -First 1
}
