Email delivery issues
Last updateresolvedSep 4 · 15:40 UTC
Email delivery to Microsoft 365/Outlook.com recipients has returned to normal. We've confirmed no new "Server busy" (4.7.500) delivery failures for over an hour, and previously delayed emails are now being delivered successfully. This aligns with Microsoft's mitigation of the underlying anti-spam enforcement issue (EX1467029). We consider this incident resolved. If you continue to experience delivery delays to Microsoft 365/Outlook.com addresses, please contact support.
