Monitoring

Microsoft is experiencing an ongoing outage affecting Outlook and Exchange Online. If your Help Scout inbox relies on Microsoft 365, (either forwarding mail into Help Scout or sending through Outlook SMTP server), you may experience delays or missing messages in incoming or outgoing email until Microsoft resolves the issue.

Inboxes that don't use Microsoft 365 aren't affected.

We're monitoring Microsoft's progress and will post an update here as things develop.
