Deleting an Application's AppRole in Azure Active Directory

Question

Removing an AppRole from an Application’s manifest produces a 400 Bad Request with the error

Property value cannot be deleted unless it is disabled first.

When I set the isEnabled property to false and then hit save, I get a successful saven with a 200 OK looking at the browsers developer tools:

After reloading the Edit manifest screen the isEnabled property is still true and if you look at the PUT response in the browsers developer tools, it's coming back as true there too.

How can I remove an appRole without having to delete and recreate the entire application?

Update

I've raised the following bug.

Answer 1

To Delete the Application Role:

1. Go to application Manifest.
2. App Role you want to delete, change the value of isEnabled to false.
3. Save the manifest.
4. Delete the that approle.
5. Again save it.

Answer 2

Until this gets fixed, there two options to work around this issue:

1. Using Azure AD PowerShell, you can disable and then remove the app role. Here's a sample script that would achieve this:

   $appId = "83d7d56d-6e64-4791-b8e8-9a8da8dd957e"
   $appRoleValue = "app-role-value" # i.e. the scope
   
   Connect-AzureAD
   
   # Disable the AppRole
   $app = Get-AzureADApplication -Filter "appId eq '$appId'"
   ($app.AppRoles | Where-Object { $_.Value -eq $appRoleValue }).IsEnabled = $false
   Set-AzureADApplication -ObjectId $app.ObjectId -AppRoles $app.AppRoles
   
   # Remove the AppRole
   $toRemove = $app.AppRoles | Where-Object { $_.Value -eq $appRoleValue }
   $app.AppRoles.Remove($toRemove) | Out-Null
   Set-AzureADApplication -ObjectId $app.ObjectId -AppRoles $app.AppRoles
   

2. An alternative option is to user the Azure AD Graph Explorer and issue two PATCH requests on the Application object. The first PATCH request should set the app role's isEnabled attribute to false. The second PATCH request can then remove the app role (i.e. include all existing app roles except the disabled one).
