Outlook outage: Will my emails disappear or fail to arrive?

Microsoft's Outlook outage continues Friday, delaying email delivery and blocking inbox access, but Microsoft says messages are not deleted and has extended the expiration window to 48 hours. The instability, which began Thursday, may cause delayed or failed deliveries if retry attempts expire, generating non-delivery reports. Microsoft extended the expiration window to 48 hours to protect pending messages, though delivery is not guaranteed. Users should check for failure notices before resending to avoid duplicates, consult IT for corporate accounts, and monitor Microsoft's status page. After access returns, review Outbox, Drafts, and Sent folders for pending items.
