I am pleased to announce that there is a new (as of 6/25/2009) version of this tool that the Exchange performance, development, and operations teams at Microsoft have used for quite some time called Exchange User Monitor (Exmon) and can be downloaded here. 

Exmon for the first time allows an Exchange administrator the ability to see in amazing detail the performance of an Exchange server.  Shown on a user by user basis, Exmon allows you to see how much CPU, latency, network traffic, and disk each user on an Exchange server consumes.  It can be run in almost realtime (minute by minute analysis) or over longer (multiple-hour) capture periods.  Exmon also 'bubbles' up data sent back to the Exchange server from Outlook 2003 and higher about the user's actual experience, showing the actual RPC (network+server) latency and even the name of the process talking to the Exchange server (so you can see ActiveSync usage and other 3rd party MAPI applications). 

The data Exmon exposes is the 'raw' data that many of the Exchange Performance counters use in calculating the running averages.

Internally, this tool was used to help understand the performance of Outlook 2003 and other MAPI applications during the development of Exchange Server 2003.  We use it to understand the broad impact of performance across a server, but also to troubleshoot specific performance problems with individual users.  The impact to the server being 'traced' is minimal, allowing it to be run on very large servers.

I'd love for you to download the tool, give it a whirl, and tell us what you think.  We'd love to see what use you can come up with for this data, problems you're able to solve, and conclusions you're able to make.

Updated part :

" It is also now available the ExPerfwiz that can enable the Exmon on a time interval basis and automation.

  • That link takes you to a version published in 6/25/2009.  Are you sure this is "new"?

  • File version I have from the 12/5/2011 download which the link points to is 14.2.247.0, NOT 14.2.247.5, which is stated on the download page.  Not sure it matters, but it's different.  Tool is very useful...

    thx
