[gotcha] Azure Key Vault objects with Purge Protection enabled cannot be permanently deleted until the retention period expires, even by subscription owners or Global Administrators

Before enabling Purge Protection on production Key Vaults, validate that your key rotation and certificate renewal automation can handle soft-deleted objects \(which still count toward subscription limits and block name reuse\); for scenarios requiring immediate cleanup of secrets \(e.g., GDPR right-to-be-forgotten\), either accept the 7-90 day retention window or architect to avoid storing PII in Key Vault, as Purge Protection cannot be overridden even by Microsoft support.

Journey Context:
Soft-delete retains deleted vaults and objects for 90 days \(configurable to 7-90 days\), allowing recovery from accidental deletion or malicious admin actions. Purge Protection is an additional guardrail that prevents even privileged users from permanently removing \('purging'\) these soft-deleted objects until the retention period passes. This creates a compliance conflict: GDPR or corporate policies may mandate immediate data destruction, but Purge Protection makes this technically impossible. Additionally, soft-deleted objects still consume subscription quotas \(e.g., max 500 versions per secret\) and block reuse of the same name, causing automation failures that assume idempotent create-or-update. Disabling Purge Protection is not allowed by Azure Policy once enabled, and Microsoft explicitly states not even Global Admin or support tickets can bypass it.
