Microsoft Exchange Online Bug Mistakenly Quarantining Mailboxes
- Engineer — Plan: Monitor Microsoft’s service health dashboard (EX1234 or similar incident ID) for resolution status; if Exchange Online is in your environment, check whether any mailboxes have been incorrectly quarantined and open a support ticket if affected.
- SOC/IR — Skip
- Leader — Learn: An availability incident affecting Exchange Online mailboxes is a business-continuity data point; no leadership action required until Microsoft’s resolution confirms scope or data impact.
