These counters provide an excellent summary of the health of the Unified Messaging server role in Microsoft Exchange Server 2007 as well as its interaction with other server roles.
| Counter | Expected values |
|---|---|

Should be less than 50 at all times. |
MSExchangeAvailability\Direct Access Failures Shows the number of times that attempts to access Active Directory failed. |
Should be 0 at all times. |

Should be 0 at all times. |
MSExchangeAvailability\Unhandled Exceptions/sec Shows the number of calls that were disconnected after an internal system error occurred in the last second. Note The name of this performance counter (Calls Disconnected on Irrecoverable Internal Error Per Second) does not match the name listed in its description. |
