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

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 Graph is limited to a m

Sending a Message in Exchange Online via REST from an Arduino MKR1000

This is part 2 of my MKR1000 article, in this previous post  I looked at sending a Message via EWS using Basic Authentication.  In this Post I'll look at using the new Outlook REST API  which requires using OAuth authentication to get an Access Token. The prerequisites for this sketch are the same as in the other post with the addition of the ArduinoJson library  https://github.com/bblanchon/ArduinoJson  which is used to parse the Authentication Results to extract the Access Token. Also the SSL certificates for the login.windows.net  and outlook.office365.com need to be uploaded to the devices using the wifi101 Firmware updater. To use Token Authentication you need to register an Application in Azure https://msdn.microsoft.com/en-us/office/office365/howto/add-common-consent-manually  with the Mail.Send permission. The application should be a Native Client app that use the Out of Band Callback urn:ietf:wg:oauth:2.0:oob. You need to authorize it in you tenant (eg build a small ap

How to test SMTP using Opportunistic TLS with Powershell and grab the public certificate a SMTP server is using

Most email services these day employ Opportunistic TLS when trying to send Messages which means that wherever possible the Messages will be encrypted rather then the plain text legacy of SMTP.  This method was defined in RFC 3207 "SMTP Service Extension for Secure SMTP over Transport Layer Security" and  there's a quite a good explanation of Opportunistic TLS on Wikipedia  https://en.wikipedia.org/wiki/Opportunistic_TLS .  This is used for both Server to Server (eg MTA to MTA) and Client to server (Eg a Message client like Outlook which acts as a MSA) the later being generally Authenticated. Basically it allows you to have a normal plain text SMTP conversation that is then upgraded to TLS using the STARTTLS verb. Not all servers will support this verb so if its not supported then a message is just sent as Plain text. TLS relies on PKI certificates and the administrative issue s that come around certificate management like expired certificates which is why I wrote th
