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"
else
wscript.echo "Last Recieved" & "," & accountname & "," & objMsg1.TimeSent
end if
if objMsg is nothing then
wscript.echo "Last Sent" & "," & accountname & "," & "No Messages"
else
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
objSession.Logoff

Exporting and Uploading Mailbox Items using Exchange Web Services using the new ExportItems and UploadItems operations in Exchange 2010 SP1

Two new EWS Operations ExportItems and UploadItems where introduced in Exchange 2010 SP1 that allowed you to do a number of useful things that where previously not possible using Exchange Web Services. Any object that Exchange stores is basically a collection of properties for example a message object is a collection of Message properties, Recipient properties and Attachment properties with a few meta properties that describe the underlying storage thrown in. Normally when using EWS you can access these properties in a number of a ways eg one example is using the strongly type objects such as emailmessage that presents the underlying properties in an intuitive way that's easy to use. Another way is using Extended Properties to access the underlying properties directly. However previously in EWS there was no method to access every property of a message hence there is no way to export or import an item and maintain full fidelity of every property on that item (you could export the...

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 Message in Exchange Online via REST from an Arduino MKR1000

This is part 2 of my MKR1000 article, in this previous post  I looked at sending a Message via EWS using Basic Authentication.  In this Post I'll look at using the new Outlook REST API  which requires using OAuth authentication to get an Access Token. The prerequisites for this sketch are the same as in the other post with the addition of the ArduinoJson library  https://github.com/bblanchon/ArduinoJson  which is used to parse the Authentication Results to extract the Access Token. Also the SSL certificates for the login.windows.net  and outlook.office365.com need to be uploaded to the devices using the wifi101 Firmware updater. To use Token Authentication you need to register an Application in Azure https://msdn.microsoft.com/en-us/office/office365/howto/add-common-consent-manually  with the Mail.Send permission. The application should be a Native Client app that use the Out of Band Callback urn:ietf:wg:oauth:2.0:oob. You ...
