Quick Check of Microsoft Exchange Access Protocol Health

Microsoft Exchange

If you need to quickly check the health of a protocol, Microsoft Exchange 2013 onwards provides a URL that you can query to ascertain the health of the service. Obviously if you query this and get nothing (i.e. a timeout) you can assume something is wrong, or if you get anything other than a “200 OK” response you know there is an issue. This mechanism can be really handy for verifying the availability of a particular Exchange Server if you are using Load Balancers in-front of your Exchange Servers that can automatically direct traffic to a functional server.

For example if you wanted to check the ActiveSync protocol health you can open in your web browser the following link:


You should be prompted for a username and password in a simple password dialog box, enter your credentials and then you’ll see (if all is well):


Where in this example, we have two Exchange Servers called EXCH-SVR-1 and EXCH-SVR-2 behind a Kemp Load Master (Load Balancer), so I’m being directed to a operating server.

You can use this same technique for other services as follows and depending on your configuration you may or may not need to login.

The possible protocol values are:

  • OWA for Outlook Web App
  • ECP for Exchange Control Panel (i.e. User Options in OWA)
  • OAB for Offline Address Book
  • AutoDiscover for the Autodiscover process (also something that is used by Lync clients)
  • EWS for Exchange Web Services (i.e. Mailtips, Free/Busy etc. Also used by Outlook for Mac)
  • Microsoft-Server-ActiveSync for Exchange ActiveSync
  • RPC for Outlook Anywhere
  • MAPI for the new MAPI/HTTPS (successor to the RPC over HTTPs protocol used in Outlook Anywhere).
