When you display the following Windows NT Performance Monitor (PerfMon) counter, it will not include the number of Anonymous Users connected to the Microsoft Exchange Information Store (IS):

Object: MSExchangeIS
Counter: Active User Count

This is by product design.


The number of Anonymous Users connected to the IS can be monitored by its own PerfMon counter. The following counter will give you this information:

Object: MSExchangeIS
Counter: Active Anonymous User Count.

The Active User Count is the number of users that have displayed activity in the past 10 minutes. By default, if an Anonymous user is idle for 10 minutes, they will be disconnected from the IS. This value is configurable. To get the total number of Active Users connected to the IS, you must add the totals of these 2 counters together.
