Exchange 2013 OWA Health Monitoring unhealthy

I have a problem with Exchange 2013 and the OWAProxyMonitor. Maybe someone can help me or tell me what I should do to get this fixed. I just opened a MS case ([REG:113061110504400]) about the problem with the OWYProxyMonitor Health Check being unhealthy.

The problem is, when I set the authentication of the OWAVirtualDirectory to Basic and Windows authentication, the OWAProxyMonitor HealthCheck becomes unhealthy and I get the following error message in the Monitoring eventlog:

-------------------------------------------------

The OWA.Proxy health set has detected a problem on EXSERVER beginning at 6/11/2013 1:21:26 PM (UTC). The health manager is reporting that recycling the MSExchangeOWAAppPool app pool has failed to restore health and it has requested the protocol be marked offline.  Attempts to auto-recover from this condition have failed and requires Administrator attention.

When I change the authentication from Basic and Windows authentication to FBA, Health Monitoring reports a healthy state of the OWAProxyMonitor.

Actually Im publishing Exchange with UAG 2010 SP3 and I have to set the OWA authentication from FBA to Basic for dont getting the double authentication problem. If I set authentication to FBA, I have to authenticate me at the UAG logon screen and then at the OWA logon (Exchange).

OWA and OWA Proxy to 2010 works internally and externally fine . The Microsoft technician told me that the health monitoring is only a visual failure and everything is OK.

Is there a solution to get this fixed?

Hello,

From the description, the issue is caused by authenticatin method.

But the health monitoring doesn't impact on your exchange server.

So far, we only refer to technet articles and blogs, but there is no explain the issue. So I recommend you contact micorosft support.

Hi,

already opened a microsoft support call with no result REG:113061110504400. Case is now closed. Is this a Bug in Exchange 2013 CU1? Will it be fixed with the next CU?

Greetings
