DLM Diagnostics

Investigate and resolve Microsoft Purview Data Lifecycle Management issues in Exchange Online. Follow the decision tree below to identify the correct troubleshooting guide, then load the matching reference file for step-by-step diagnostic instructions.

Prerequisites

Before running any diagnostic commands, ensure both PowerShell sessions are connected:

Connect-ExchangeOnline -UserPrincipalName '<admin@contoso.com>' -ShowBanner:$false
Connect-IPPSSession -UserPrincipalName '<admin@contoso.com>' -ShowBanner:$false

Safety Rules

Only execute read-only commands. Allowed cmdlet verbs: Get-*, Test-*, Export-*.

Never execute mutating commands — Set-*, New-*, Remove-*, Enable-*, Start-*, Invoke-* cmdlets must only be returned as text recommendations for the admin to review and run manually.
