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

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 ...

How to test SMTP using Opportunistic TLS with Powershell and grab the public certificate a SMTP server is using

Most email services these day employ Opportunistic TLS when trying to send Messages which means that wherever possible the Messages will be encrypted rather then the plain text legacy of SMTP.  This method was defined in RFC 3207 "SMTP Service Extension for Secure SMTP over Transport Layer Security" and  there's a quite a good explanation of Opportunistic TLS on Wikipedia  https://en.wikipedia.org/wiki/Opportunistic_TLS .  This is used for both Server to Server (eg MTA to MTA) and Client to server (Eg a Message client like Outlook which acts as a MSA) the later being generally Authenticated. Basically it allows you to have a normal plain text SMTP conversation that is then upgraded to TLS using the STARTTLS verb. Not all servers will support this verb so if its not supported then a message is just sent as Plain text. TLS relies on PKI certificates and the administrative issue s that come around certificate management like expired certificates which is why ...
