Reporting on Inbox Rules with OWA via Script

I've been looking at inbox rules lately and how you can manipulate them via script. Not a really easy thing currently, there is a rule.dll you can use with CDO to create rules but management and reporting are hard tasks. Firstly I wanted to just know how many people on my server where actually using inbox rules. I looked at doing a query of all the rule messages in the inbox but I found this wasn't too accurate a way of reporting on Inbox rules because you tended to pick up all the junk email rules and any other rules whether it was active or not and I really only wanted to know about user created server side inbox rules. I had a look at how OWA was doing it and this seemed to be something I could make use of, all it did was make one get /inbox/?cmd=rules and then this returned a list of all the active inbox rules. So all I needed to put together was a ADSI query of all the users on the Exchange box and put something that would parse the result returned from the OWA get and this is the result. To do this im reusing some OWA commands and the (Microsoft.XMLHTTP) Object i described this method is this blog entry

set rootDSE = GetObject("LDAP://rootDSE")
defaultNamingContext = rootDSE.Get("defaultNamingContext")
Set objSysInfo = CreateObject("ADSystemInfo")

GALQueryFilter = "(&(&(& (mailnickname=*) (| (&objectCategory=person)(objectClass=user)(|(homeMDB=*)(msExchHomeServerName=*)))
))))"
strQuery = "<LDAP://" & objSysinfo.domaindnsname & "/" & defaultNamingContext & ">;" & GALQueryFilter & ";samaccountname;subtree"

Set oConn = CreateObject("ADODB.Connection") 'Create an ADO Connection
oConn.Provider = "ADsDSOOBJECT" ' ADSI OLE-DB provider
oConn.Open "ADs Provider"

Set oComm = CreateObject("ADODB.Command") ' Create an ADO Command
oComm.ActiveConnection = oConn
oComm.Properties("Page Size") = 1000
oComm.CommandText = strQuery
oComm.Properties("Sort on") = "givenname"

Set rs = oComm.Execute
while not rs.eof
cmdexe = rs.fields("Samaccountname")
getrules(cmdexe)
rs.movenext
wend

function getrules(mname)

oXmlHttp.Open "get", "http://mgnms01/exchange/" & mname & "/inbox/?cmd=rules",False, "", ""

oXmlHttp.setRequestHeader "Content-type:", "application/x-www-UTF8-encoded"

wscript.echo mname & "," & rules & "," & rcount & rnames
