Somethings wrong, horribly wrong.
Exchange server has stopped delivering mail to mailboxes.
OWA says "HTTP/1.1 503 Service Unavailable".
Inetinfo.exe is running at top CPU usage.
110 mails in local SMTP queue.
All MSExchange services are running according to "SolarWinds Exchange Monitor"
Very close to panicking. What can i do? 500p to solve.
