Possible Errors and Solutions

Error	Cause	Solution
InvalidRequest	An invalid or malformed parameter was provided.	Verify the -GroupLifecyclePolicyId value and ensure it is accurate.
ResourceNotFound	The specified lifecycle policy ID does not exist.	Confirm the policy ID using Get-MgGroupLifecyclePolicy without the -GroupLifecyclePolicyId parameter to list all policies.
Authentication_ExpiredToken	The authentication token used has expired.	Re-authenticate with Connect-MgGraph and rerun the command.
PermissionDenied	Insufficient permissions for the account executing the cmdlet.	Ensure the account has the necessary roles, such as Azure AD administrator or Microsoft 365 Global Administrator and necessary permission like Directory.ReadWrite.All

The Get-MgGroupLifecyclePolicy cmdlet is essential for managing and auditing lifecycle policies in Microsoft 365 groups. By leveraging its capabilities, administrators can ensure compliance, troubleshoot issues, and automate reporting.
