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)
on error resume next
Set oXmlHttp = CreateObject("Microsoft.XMLHTTP")
oXmlHttp.Open "get", "http://mgnms01/exchange/" & mname & "/inbox/?cmd=rules",False, "", ""
oXmlHttp.setRequestHeader "Accept-Language:", "en-us"
oXmlHttp.setRequestHeader "Content-type:", "application/x-www-UTF8-encoded"
oXmlHttp.setRequestHeader "Content-Length:", Len(szXml)
oXmlHttp.Send szXml
slen = instr(oXmlHttp.responseText,"<TABLE id=""tblRules""")
elen = instr(slen,oXmlHttp.responseText,"</TABLE>")
pstring = mid(oXmlHttp.responseText,slen,elen-slen)
slen1 = 1
rules = "no"
rcount = 0
do until stopit = 1
if instr(slen1,pstring,"nowrap") then
slen1 = instr(slen1,pstring,"nowrap")+13
elen1 = instr(slen1,pstring,"</TD>")
rnames = rnames & "," & mid(pstring,slen1,elen1-slen1)
slen1 = elen1
rules = "yes"
rcount = rcount + 1
else
stopit = 1
end if
loop
wscript.echo mname & "," & rules & "," & rcount & rnames

end function

Exporting and Uploading Mailbox Items using Exchange Web Services using the new ExportItems and UploadItems operations in Exchange 2010 SP1

Two new EWS Operations ExportItems and UploadItems where introduced in Exchange 2010 SP1 that allowed you to do a number of useful things that where previously not possible using Exchange Web Services. Any object that Exchange stores is basically a collection of properties for example a message object is a collection of Message properties, Recipient properties and Attachment properties with a few meta properties that describe the underlying storage thrown in. Normally when using EWS you can access these properties in a number of a ways eg one example is using the strongly type objects such as emailmessage that presents the underlying properties in an intuitive way that's easy to use. Another way is using Extended Properties to access the underlying properties directly. However previously in EWS there was no method to access every property of a message hence there is no way to export or import an item and maintain full fidelity of every property on that item (you could export the...

The MailboxConcurrency limit and using Batching in the Microsoft Graph API

If your getting an error such as Application is over its MailboxConcurrency limit while using the Microsoft Graph API this post may help you understand why. Background   The Mailbox  concurrency limit when your using the Graph API is 4 as per https://docs.microsoft.com/en-us/graph/throttling#outlook-service-limits . This is evaluated for each app ID and mailbox combination so this means you can have different apps running under the same credentials and the poor behavior of one won't cause the other to be throttled. If you compared that to EWS you could have up to 27 concurrent connections but they are shared across all apps on a first come first served basis. Batching Batching in the Graph API is a way of combining multiple requests into a single HTTP request. Batching in the Exchange Mail API's EWS and MAPI has been around for a long time and its common, for email Apps to process large numbers of smaller items for a variety of reasons.  Batching in the Gr...

EWS-FAI Module for browsing and updating Exchange Folder Associated Items from PowerShell

Folder Associated Items are hidden Items in Exchange Mailbox folders that are commonly used to hold configuration settings for various Mailbox Clients and services that use Mailboxes. Some common examples of FAI's are Categories,OWA Signatures and WorkHours there is some more detailed documentation in the https://msdn.microsoft.com/en-us/library/cc463899(v=exchg.80).aspx protocol document. In EWS these configuration items can be accessed via the UserConfiguration operation https://msdn.microsoft.com/en-us/library/office/dd899439(v=exchg.150).aspx which will give you access to either the RoamingDictionary, XMLStream or BinaryStream data properties that holds the configuration depending on what type of FAI data is being stored. I've written a number of scripts over the years that target particular FAI's (eg this one that reads the workhours  http://gsexdev.blogspot.com.au/2015/11/finding-timezone-being-used-in-mailbox.html is a good example ) but I didn't have a gene...
