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)(|
Com.ActiveConnection = Conn
Com.CommandText = Query
Com.Properties("Page Size") = 1000
Set Rs = Com.Execute
wfile.writeline("Mailbox,TelephoneNumber,Mobile Number,Home Phone,Street
While Not Rs.EOF
wfile.writeline(rs.fields("displayname").value & "," &
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
end if
wscript.echo "User" & dnUserDN
for count = 1 to intRes
select case objIadsTools.MetaDataName(count)
case "telephoneNumber" wscript.echo "Telephone Number last write: " &
tnTelephoneNumber = objIadsTools.MetaDataLastWriteTime(count)
case "mobile" wscript.echo "Mobile Number last write: " &
mnMobileNumber = objIadsTools.MetaDataLastWriteTime(count)
case "homePhone" wscript.echo "Home Phone Number last write: " &
hnHomePhone = objIadsTools.MetaDataLastWriteTime(count)
case "streetAddress" wscript.echo "Street Address last write: " &
saStreetAddress = objIadsTools.MetaDataLastWriteTime(count)
case "physicalDeliveryOfficeName" wscript.echo "Office last write: " &
ofOffice = objIadsTools.MetaDataLastWriteTime(count)
end select
dlDataline = tnTelephoneNumber &amp; "," & mnMobileNumber & "," & hnHomePhone & ","

Export calendar Items to a CSV file using EWS and Powershell

Somebody asked about this last week and while I have a lot of EWS scripts that do access the Calendar I didn't have a simple example that just exported a list of the Calendar events with relevant information to a CSV file so here it is.

I've talked on this one before in this howto  but when you query the calendar folder using EWS you need to use a CalendarView which will expand any recurring appointments in a calendar. There are some limits when you use a calendarview in that you can only return a maximum of 2 years of appointments at a time and paging will limit the max number of items to 1000 per call. So if you have a calendar with a very large number of appointments you need to break your query into small date time blocks. In this example script I'm just grabbing the next 7 days of appointments if you want to query a longer period you need to adjust the following lines (keeping in mind what I just mentioned)

#Define Date to Query
$StartDate = (Get-Date)
$EndDate = (Ge…

EWS Managed API and Powershell How-To series Part 1

I thought I'd start the year with a series of posts that goes back over the basics of using the EWS Managed API from Powershell and provides a modular remarked example that you can easily cut and paste to build your own scripts. Along the way in this series I'll show a whole bunch of examples around specific things.

As a starting point for versions this will be Powershell Version 2.0  and the EWS Managed API 1.1 (which will soon change to 1.2 once released)

The starting point for any EWS script your going to write is connecting to Exchange for which there are three important pieces of information you will need. Firstly you need to know the version of Exchange your running in this script its going to be held in the following variable

$ExchangeVersion = [Microsoft.Exchange.WebServices.Data.ExchangeVersion]::Exchange2010_SP1

Other valid values for Exchange 2007 would be

$ExchangeVersion = [Microsoft.Exchange.WebServices.…

Writing a simple scripted process to download attachmentts in Exchange 2007/ 2010 using the EWS Managed API

Every complicated thing in life is made up of smaller simpler building blocks, when it comes to writing a script (or any code really) the more of these little building blocks you have to figure out the more the process of solving a problem can become bewildering. The Internet generally provides you with lots of half eaten sandwiches of information something someone else has taken a bite out but a lot of the time half done, and as with any code its usefulness declines over time as new and better API's and methods are derived. In this post I'm going to go through a simple scripted process that hopefully covers a few more of these smaller building blocks that you might face when asked to come up with a simple costless solution to perform an automated business function with a script.

So the process im going to look at is one that comes up a lot and that is you have an Email that comes into to certain mailbox every day with a certain subject in my case "Daily Export" this …
