How to log all queries to Outlook Web Access (msexchange 2010)

We have MS Exchange 2010 with Outlook Web Access.

IIS logging is enable. It works for everything like :

• /RPC/*
• /autodiscover/*
• ...

And it works also for :

• /OWA
• /owa/auth/logon.aspx
• /owa/ev.owa

But it doesn't work for queries like :

• /owa/?ae=Folders*
• /owa/?ae=Item*

How can I fix the configuration to log all queries ?

The difference between the logged requests and the not logged ones is the query string which is present only on the later (the part after the '?' charcater).

You have to enable printing the query string on IIS'l log, here you can find more information on how to do it:
