The New-MgApplicationOwnerByRef cmdlet in Microsoft Graph PowerShell is a powerful tool for managing the owners of Azure AD applications. This cmdlet allows administrators to assign one or more owners to an application by referencing their User IDs in a specific URL format. In this article, we will explore the cmdlet's syntax, provide usage examples (including assigning a single owner, multiple owners, and importing owners from a CSV file), offer tips for effective usage, and discuss possible errors and their solutions.
Note: You need Application Ids to work with this cmdlet. Use Get-MgApplication to get the application id.
New-MgApplicationOwnerByRef -ApplicationId <String> -BodyParameter <Hashtable>
To assign a single owner to an application, you need to provide the Application ID and the User ID of the new owner. The User ID must be passed in the correct URL format.
$NewOwner = @{
"@odata.id"= "https://graph.microsoft.com/v1.0/directoryObjects/075b32dd-edb7-47cf-89ef-f3f733683a3f"
}
New-MgApplicationOwnerByRef -ApplicationId "1a2b3c4d-5678-90ab-cdef-1234567890ab" -BodyParameter $NewOwner
If you want to assign multiple owners, you need to run the New-MgApplicationOwnerByRef cmdlet multiple times, each time with a different @odata.id.
$Owner1 = @{
"@odata.id"= "https://graph.microsoft.com/v1.0/directoryObjects/075b32dd-edb7-47cf-89ef-f3f733683a3f"
}
$Owner2 = @{
"@odata.id"= "https://graph.microsoft.com/v1.0/directoryObjects/12345678-1234-1234-1234-1234567890ab"
}
New-MgApplicationOwnerByRef -ApplicationId "1a2b3c4d-5678-90ab-cdef-1234567890ab" -BodyParameter $Owner1
New-MgApplicationOwnerByRef -ApplicationId "1a2b3c4d-5678-90ab-cdef-1234567890ab" -BodyParameter $Owner2
You can also assign multiple owners by importing User IDs from a CSV file and iterating over each ID.
Sample CSV File (Owners.csv):
UserId
075b32dd-edb7-47cf-89ef-f3f733683a3f
12345678-1234-1234-1234-1234567890ab
PowerShell Script:
$ApplicationId = "1a2b3c4d-5678-90ab-cdef-1234567890ab"
$Owners = Import-Csv -Path "C:\Path\To\Owners.csv"
foreach ($Owner in $Owners) {
$NewOwner = @{
"@odata.id" = "https://graph.microsoft.com/v1.0/directoryObjects/$($Owner.UserId)"
}
New-MgApplicationOwnerByRef -ApplicationId $ApplicationId -BodyParameter $NewOwner
}
Cause: The token used for authentication is invalid or expired.
Solution: Ensure you have a valid authentication token. Run Connect-MgGraph to re-authenticate.
Cause: The specified Application ID or User ID is incorrect.
Solution: Verify that both the Application ID and User IDs are correct and exist in the tenant.
Cause: The @odata.id format is incorrect.
Solution: Ensure that the User ID is correctly formatted in the URL and that it matches the expected format.
The New-MgApplicationOwnerByRef cmdlet is an essential tool for managing the ownership of Azure AD applications through Microsoft Graph PowerShell.
