What problem does it solve? Offboarding a leaver's mailbox requires preserving email for seven years while freeing the licence seat, and doing it wrong (removing the licence instead of deleting the account) silently destroys the mailbox in 30 days. This Skill walks a non-technical operator through the entire Exchange Online mailbox cleanup runbook one step at a time, printing exact commands and verifying every result. ## Core Features & Use Cases - Guided 41-step runbook: Covers five phases from ServiceDesk Plus ticket creation and PowerShell module preflight through seven-year Litigation Hold application, account deletion (on-prem AD with Entra Connect delta sync or cloud-only Remove-MgUser), inactive-mailbox validation, and Purview eDiscovery export. - Operator-safe execution model: The Skill prints copy-pasteable Windows PowerShell 5.1 commands for the operator to run; it never runs Connect-ExchangeOnline or mutating cmdlets itself, and gates account deletion behind a typed confirmation. - Bundled helper scripts: Includes exo_preflight.ps1 for module/role checks and per-user installs, Resolve-OperatorInput.ps1 for normalizing a single address or CSV of leavers, and Read-ScriptLog.ps1 for decoding logs with correct encodings. - Use Case: HR confirms three leavers; the operator gives the Skill their addresses, and it drives the hold application, verifies preservation with item-count baselines, deletes the accounts after sign-off, and proves the mail is still searchable in Purview. ## Quick Start Ask the assistant to put a leaver's mailbox on litigation hold and delete their account, providing their email address or a CSV of leavers.
