Health check for different exchange 2013 protocols

Thommy Weiss / pixelio.de

Since Exchange 2013 Microsoft has implemented a URL for each protocol that can be easily checked for the health state. The format would be:


This htm content is dynamicaly createt in the memory of the systeme at the runtime of the protocol. It does not exists in the directory of the IIS.

The Exchange Server response with the follwing content it the protocol works correctly:

250 ok

For the protocol the follwoing values can be used:

OWAOutlook Web App
ECPExchange Control Panel (i.e. User Options in OWA)
OABOffline Address Book
AutodiscoverAutodiscover process (also something that is used by Lync clients)
EWSfor Exchange Web Services (i.e. Mailtips, Free/Busy etc. Also used by Lync clients, Outlook for Mac etc.)
Microsoft-Server-ActiveSyncExchange ActiveSync
RPCOutlook Anywhere
MAPIMAPI/HTTPS (successor to the RPC over HTTPs protocol used in Outlook Anywhere). You’ll need at least Exchange 2013 SP1

This actually Healtcheck URLs can also be used by Loadbalancers to check the server health or the protocol health.

  • No authentication is needed
  • Depend on the FQDN the check works from inside and outside
  • If the server have an issue , you can expect other repsones the „200 OK“, or timeouts
  • If you have multiple Exchange Severs behind a Loadbalancer, you will only get the respone from one server at a time. Depending of the configuration resumbitting the request can reult in a response from another Exchage Server.
