Finding Stale Address and Telephone information in the GAL with a script

I came across this while actually looking for something else but it does go some way to answering another question that gets asked occasionally. If you want to use the information in the GAL (eg Active Directory) for phone numbers and address’s ect how up to date is this information eg can I find out the last time it was updated. While maybe not 100% accurate one method that you maybe able to use is to use the Metadata from Active Directory which stores information about when the last time each property was updated and replicated in Active directory.

To access the metadata from a script you need to use the iadstools.dll which comes as part of the Windows 2000/3 Support Tools package which can be found on the server CD in Support\Tools folder. Robbie Allen has put together a number of samples on using the objects in this DLL in his Active Directory cookbook which is worth checking out here. For this script I’ve expanded greatly on one of his samples by including a query of ever mailbox in the GAL and then feeding in the DN of each user to grab the metadata about each property and then using a few case statements to filter that data a little further to just the telephone numbers and a few address property such as Street Address and Office. I then feed the data into a CSV file so you can then open this up in Excel and do extra filtering etc.

This is really just scratching the surface of what you can do with this library is terms of diagnosing replication problems etc.

To run the script you need to have the Windows 2000/3 Support Tools installed so you will have the iadstools.dll registered. The script takes one commandline parameter which is the name of the Domain Controller you want to run it against. Eg

Cscript adrlastupdated.vbs domaincontrollernetbiosName

I’ve put a downloadable copy of the script here there script itself look like

dcDomainController = wscript.arguments(0)
set objIadsTools = CreateObject("IADsTools.DCFunctions")
set conn = createobject("ADODB.Connection")
set com = createobject("ADODB.Command")
Set iAdRootDSE = GetObject("LDAP://RootDSE")
Set fso = CreateObject("Scripting.FileSystemObject")
set wfile = fso.opentextfile("c:\temp\AdrinfoLastupdated.csv",2,true)
strNameingContext = iAdRootDSE.Get("defaultNamingContext")
Conn.Provider = "ADsDSOObject"
Conn.Open "ADs Provider"
Query = "<LDAP://" & strNameingContext &amp; ">;(&(&(& (mailnickname=*)(mailnickname=*)(!msExchHideFromAddressLists=TRUE)(|
(&(objectCategory=person)(objectClass=user)(|(homeMDB=*)(msExchHomeServerName=*)))
))));distinguishedName,displayname;subtree"
Com.ActiveConnection = Conn
Com.CommandText = Query
Com.Properties("Page Size") = 1000
Set Rs = Com.Execute
wfile.writeline("Mailbox,TelephoneNumber,Mobile Number,Home Phone,Street
Address,Office")
While Not Rs.EOF
wfile.writeline(rs.fields("displayname").value & "," &
getUserData(dcDomainController,rs.fields("distinguishedName")))
rs.movenext
Wend
wfile.close
set wfile = nothing
set fso = Nothing



function getUserData(dcDomainController,dnUserDN)
dlDataline = ""
tnTelephoneNumber = "Not Set"
mnMobileNumber = "Not Set"
hnHomePhone = "Not Set"
saStreetAddress = "Not Set"
ofOffice = "Not Set"

intRes = objIadsTools.GetMetaData(Cstr(dcDomainController),Cstr(dnUserDN),0)

if intRes = -1 then
Wscript.Echo objIadsTools.LastErrorText
WScript.Quit
end if
wscript.echo "User" & dnUserDN
for count = 1 to intRes
select case objIadsTools.MetaDataName(count)
case "telephoneNumber" wscript.echo "Telephone Number last write: " &
objIadsTools.MetaDataLastWriteTime(count)
tnTelephoneNumber = objIadsTools.MetaDataLastWriteTime(count)
case "mobile" wscript.echo "Mobile Number last write: " &

mnMobileNumber = objIadsTools.MetaDataLastWriteTime(count)

case "physicalDeliveryOfficeName" wscript.echo "Office last write: " &
objIadsTools.MetaDataLastWriteTime(count)
ofOffice = objIadsTools.MetaDataLastWriteTime(count)

next
wscript.echo

getUserData = dlDataline

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...
