Script to Copy Public folder contacts to a mailbox's Contacts folder using CDO 1.2

Somebody asked today about this script I posted a while ago about copying contacts between mailbox's using the vCard method in CDOEX. While this script works okay for simple contacts if you have rich contacts where you have lots of additionally information that CDOEX doesn't include in the vcard stream then it can be a lot of work going through and copying each one of these Mapi properties manually (which I've already done for a few props in this script). The other option if you want to do this in a script is to use MAPI via CDO 1.2. The big advantage of using MAPI is that you will retain all the MAPI properties as they are on the object and also you can run the script remotely where the CDOEX script must be run locally on the Exchange server. The actually question was about copying contacts from a public folder to a mailbox so I've come up with a script that will do this using MAPI via CDO 1.2. To use this script you need to know the entryID for the public folder where the contacts are stored .You can find the folder entryID using something like Outlookspy or Mdbvu32 (from the exchange support tools directory) or I've included a simple utility script that will output what the entryID of a store item is from the OWA URL. This simple utility script look like.

OWAURL = "http://server/public/folder"
set xmlobjreq = createobject("Microsoft.XMLHTTP")
xmlreqtxt = "<?xml version='1.0'?><a:propfind xmlns:a='DAV:'
xmlns:e='http://schemas.microsoft.com/mapi/proptag/

'><a:prop><e:x0FFF0102/></a:prop></a:propfind>"
xmlobjreq.open "PROPFIND", OWAURL, false, "", ""
xmlobjreq.setRequestHeader "Content-Type", "text/xml; charset=""UTF-8"""
xmlobjreq.setRequestHeader "Depth", "0"
xmlobjreq.setRequestHeader "Translate", "f"
xmlobjreq.send xmlreqtxt
set oResponseDoc = xmlobjreq.responseXML
set oNodeList = oResponseDoc.getElementsByTagName("d:x0FFF0102")
For i = 0 To (oNodeList.length -1)
set oNode = oNodeList.nextNode
wscript.echo Octenttohex(oNode.nodeTypedValue)
Next

Function Octenttohex(OctenArry)
ReDim aOut(UBound(OctenArry))
For i = 1 to UBound(OctenArry) + 1
if len(hex(ascb(midb(OctenArry,i,1)))) = 1 then
aOut(i-1) = "0" & hex(ascb(midb(OctenArry,i,1)))
else
aOut(i-1) = hex(ascb(midb(OctenArry,i,1)))
end if
Next
Octenttohex = join(aOUt,"")
End Function


The script that copies the contacts from a public folder to mailbox's contact folder looks like I've put a downloadable copy of both scripts here. Remember these scripts do a dumb copy so they will just copy or duplicate contacts with no intelligence so used inappropriately they could cause duplicate contact issues.


servername = "servername"
mailbox = "mailbox"
pubContactsfolderid = "00000....etc"
set objSession = CreateObject("MAPI.Session")
strProfile = servername & vbLf & mailbox
objSession.Logon "",,, False,, True, strProfile
Set objcontactfolder = objSession.getdefaultfolder(5)
Set objInfoStore = objSession.GetInfoStore(objSession.Inbox.StoreID)
Set objpubstore = objSession.InfoStores("Public Folders")
set objpubContactsfolder = objSession.getfolder(pubContactsfolderid,objpubstore.id)
for each objcontact in objpubContactsfolder.messages
set objCopyContact = objcontact.copyto(objcontactfolder.ID,objInfoStore.ID)
objCopyContact.Unread = false
objCopyContact.Update
Set objCopyContact = Nothing
wscript.echo objcontact.subject
next
objsession.Logoff

Testing and Sending email via SMTP using Opportunistic TLS and oAuth in Office365 with PowerShell

As well as EWS and Remote PowerShell (RPS) other mail protocols POP3, IMAP and SMTP have had OAuth authentication enabled in Exchange Online (Official announcement here ). A while ago I created  this script that used Opportunistic TLS to perform a Telnet style test against a SMTP server using SMTP AUTH. Now that oAuth authentication has been enabled in office365 I've updated this script to be able to use oAuth instead of SMTP Auth to test against Office365. I've also included a function to actually send a Message. Token Acquisition  To Send a Mail using oAuth you first need to get an Access token from Azure AD there are plenty of ways of doing this in PowerShell. You could use a library like MSAL or ADAL (just google your favoured method) or use a library less approach which I've included with this script . Whatever way you do this you need to make sure that your application registration  https://docs.microsoft.com/en-us/azure/active-directory/develop/quickstart-register-

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

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
