Finding Unused Mailboxes with CDO 1.2

A while ago I posted this script on OutlookExchange that uses Exoledb to find unused mailboxes on a Exchange 2000 server by looking at the unread mail count in the inbox for the last 50 days. Since then I've have a few questions for people wanting to know if they could do this also in Exchange 5.5 mainly to assist in migrations and cleanups. The answer is yes you can but not with Exoledb which is only available on Exchange 2000 and up, what you can use is CDO 1.2 to do something similar.

Another good thing about using CDO 1.2 to do this is you can go a bit further then I did with the simple Exoledb sample by using some of CDO 's cool little built in methods. This is an example of a CDO script that will display the received time of the newest email in the inbox, the sent time of the last mail sent from this mailbox and the unread count for the last 50 days. It logs on to a mailbox using a dynamic profile you supply the alias name as a command line parameter and you need to hardcode the servername in the script.

accountname = WScript.Arguments(0)
set objSession = CreateObject("MAPI.Session")
strProfile = "yourserver" & vbLf & accountname
objSession.Logon "","",False,True,0,True,strProfile
set objFolder1 = objSession.Inbox
set objMsgs1 = objFolder1.Messages
set objMsg1 = objMsgs1.Getlast
set objFolder = objSession.GetDefaultFolder(3)
set objMsgs = objFolder.Messages
set objMsg = objMsgs.Getlast
if objMsg1 is nothing then
wscript.echo "Last Recieved" & "," & accountname & "," & "No Messages"
wscript.echo "Last Recieved" & "," & accountname & "," & objMsg1.TimeSent
end if
if objMsg is nothing then
wscript.echo "Last Sent" & "," & accountname & "," & "No Messages"
wscript.echo "Last Sent" & "," & accountname & "," & objMsg.TimeSent
end if
objFolder1.Messages.Filter.Unread = False
set objMsgFilter = objMsgs1.Filter
objMsgFilter.Unread = True
objMsgFilter.TimeFirst = now()-50
wscript.echo "Number of Unread" & "," & accountname & "," & objMsgs1.count

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 …
