Reporting on the number of Users, Contacts and Groups in a OU and sub OU’s

Somebody asked how to do this last week and I’ve had a few other question’s lately on reporting based on Sub Ou’s so I thought I’d put together a sample to show one method of doing this. The method I’ve used is to create a data-shape of all the objects with a Ou and its Sub Ou’s and then relate this information to an enumeration of the OU tree.

What this script does is takes the name of the OU where you want to start the query at as a command-line parameter. It then does an ADSI query to find the distinguished name of the first OU that matches the text entered. It then does 3 separate subtree queries of all the Users, contacts and group objects that are located under the root OU. To group the information that is returned this is where the ADO datashaping provider is used. The information is then stored temporary in a multi dimensional array and then used to finally build a HTM report called “c:\temp\report.htm” which has a table that shows the OU Name, Description, Path and the number of users, groups and contacts within each OU.

The script takes one command-line parameter which is the name of the OU you want to run it against eg to run the script “cscript.exe lobjectsv2.vbs OUname”. I’ve also created a provision to let the script be run against the entire Active Directory domain instead of just and OU branch to do this instead of using the name of the OU as a command-line parameter use rootdse as the command-line parameter eg “cscript lobjectsv2.vbs rootdse”

I’ve put a downloadable copy of the code here the script looks like


queryou = wscript.arguments(0)
report = "<table border=""1"" width=""100%"">" & vbcrlf
report = report & " <tr>" & vbcrlf
report = report & "<td align=""center"" bgcolor=""#000080""><b><font color=""#FFFFFF"">OU

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...

Sending a MimeMessage via the Microsoft Graph using the Graph SDK, MimeKit and MSAL

One of the new features added to the Microsoft Graph recently was the ability to create and send Mime Messages (you have been able to get Message as Mime for a while). This is useful in a number of different scenarios especially when trying to create a Message with inline Images which has historically been hard to do with both the Graph and EWS (if you don't use MIME). It also opens up using SMIME for encryption and a more easy migration path for sending using SMTP in some apps. MimeKit is a great open source library for parsing and creating MIME messages so it offers a really easy solution for tackling this issue. The current documentation on Send message via MIME lacks any real sample so I've put together a quick console app that use MSAL, MIME kit and the Graph SDK to send a Message via MIME. As the current Graph SDK also doesn't support sending via MIME either there is a workaround for this in the future my guess is this will be supported.

Export calendar Items to a CSV file using Microsoft Graph and Powershell

For the last couple of years the most constantly popular post by number of views on this blog has been  Export calendar Items to a CSV file using EWS and Powershell closely followed by the contact exports scripts. It goes to show this is just a perennial issue that exists around Mail servers, I think the first VBS script I wrote to do this type of thing was late 90's against Exchange 5.5 using cdo 1.2. Now it's 2020 and if your running Office365 you should really be using the Microsoft Graph API to do this. So what I've done is create a PowerShell Module (and I made it a one file script for those that are more comfortable with that format) that's a port of the EWS script above that is so popular. This script uses the ADAL library for Modern Authentication (which if you grab the library from the PowerShell gallery will come down with the module). Most EWS properties map one to one with the Graph and the Graph actually provides better information on recurrences then...
