There are two issues here:
1) The logs are not being recognized. You can use the search bar in the Exchange app to search for eventtype=client-iis-logs - it should produce results. If that works, try searching for eventtype=client-owa-usage to see just the OWA information. If these produce data, the dashboards should be populated as well. If the former (client-iis-logs) does not produce data, then it's likely to be an IIS log extraction problem - ensure the MSWindows:*:IIS sourcetype is in the msexchange index or the eventtype definition (in eventtypes.conf) points to the right place. Also, ensure the fields (cs_username, cs_uri_path, etc.) are being extracted. If it isn't, then the transforms.conf in both the TA-Windows-2008R2-IIS and the Splunk_for_Exchange app needs to be altered to match the actual log format.
2) Perfmon is not being pulled properly. Microsoft likes to rename perfmon counters on a regular basis. The actual perfmon counter names are stored in perfmon.conf and used through out the app for plotting. However, they are also documented on technet, which is what we used for this gathering. Use perfmon.exe to get the real names from your system. If your system is not producing specific perfmon counters, remove them from perfmon.conf. (The logs saying Invalid counter are annoying, but harmless, and not counted towards your license usage).
As always, if you have a support contract, feel free to open up a support case. Splunk App for Microsoft Exchange is a supported app.
