Azure Update Manger - Cannot edit maintenance configurations that were created with Powershell

Question

1. Use the command 'New-AzMaintenanceConfiguration' to create a maintenance configuration.
2. Then, attempt to manually add or remove a KB to 'exclusions' in the Updates part of the schedule using the normal Azure Portal Web interface.
3. The issues is - I'm unavble to save any changes to a maintenance configuration through the GUI if it’s been created using Powershell.

If the maintenance configuration is created using the Azure Portal web interface manually, this isn't a problem.

Any suggestions or workarounds? This is problematic bug.

Here's powershell sample:

$ResourceGroupName = "YOUR-RESOURCEGROUP-NAME"
$Name = "YOUR NAME"
$MaintenanceScope = "InGuestPatch"
$Location = "uksouth"
$StartDateTime = "2024-11-14 12:00"
$ExpirationDateTime = "2024-12-04 17:00"
$TimeZone = "GMT Standard Time"
$Duration = "03:00"
$RecurEvery = "Day"
$InstallPatchRebootSetting = "IfRequired"
$Visibility = "Custom"

# Assuming these are the classifications you want to include
$WindowParameterClassificationToInclude = "Critical", "Security", "UpdateRollup", "FeaturePack", "ServicePack", "Definition", "Tools", "Updates"

# Assuming these are the KB numbers you want to exclude
$WindowParameterKbNumberToExclude = "KB5002501", "KB5002517", "KB5002541"

# ExtensionProperty should be a hashtable
$ExtensionProperty = @{
    "InGuestPatchMode" = "User"
}

New-AzMaintenanceConfiguration `
-ResourceGroupName $ResourceGroupName `
-Name $Name `
-MaintenanceScope $MaintenanceScope `
-Location $Location `
-StartDateTime $StartDateTime `
-ExpirationDateTime $ExpirationDateTime `
-TimeZone $TimeZone `
-Duration $Duration `
-RecurEvery $RecurEvery `
-WindowParameterClassificationToInclude $WindowParameterClassificationToInclude `
-WindowParameterKbNumberToExclude $WindowParameterKbNumberToExclude `
-InstallPatchRebootSetting $InstallPatchRebootSetting `
-Visibility $Visibility `
-ExtensionProperty $ExtensionProperty `
-Debug

Eccup Reservoir, Thank you again for reporting this issue.

The fix for this issue is already released and you should be able to edit the maintenance configuration from portal - even those which were created using Azure PowerShell.

Please check and confirm (I tested it in my subscription, and it worked) and do let me know if you have any questions.
