Post IMF Archiving Event Sink

Once the IMF has achieved a message this is pretty final in regards to the delivery of this message, but it doesn't have to be so what you can do is create a WMI consumer on the archive directory so every time a message gets archived it will then trigger an event.  After this you can then open the new mail that was just archived using CDO have a look at who it was going to or do further inspection on the content and if you think that this message should have been delivered move it back into the pickup directory and have it delivered. The logic and things you can do with this is up to your own imagination one simple example is if you have an account that you want to allow all mail though no matter what this script will check the x-receiver field if the mail is going to that user it will then move the email into the pickup directory. You can set this up as a permanent consumer using a Mof file or my preference is to use Srvany and create a service that this script runs as.


strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" & _
strComputer & "\root\cimv2")
Set colMonitoredEvents = objWMIService.ExecNotificationQuery _
("SELECT * FROM __InstanceCreationEvent WITHIN 10 WHERE " _
& "Targetinstance ISA 'CIM_DirectoryContainsFile' and " _
& "TargetInstance.GroupComponent= " _
& "'Win32_Directory.Name=""c:\\\\program files\\\\exchsrvr\\\\mailroot\\\\vsi 1\\\\ucearchive""'")
Do
Set objLatestEvent = colMonitoredEvents.NextEvent
set msgobj = createobject("CDO.Message")
fname = objLatestEvent.TargetInstance.PartComponent
set stm = createobject("ADODB.Stream")
stm.open
fname = replace(fname,"\\","\")
fname = right(fname,len(fname) - instr(fname,chr(34)))
fname = replace(fname,chr(34),"")
stm.loadfromfile fname
msgobj.datasource.openobject stm, "_Stream"
wscript.echo msgobj.fields("urn:schemas:mailheader:x-receiver")
if msgobj.fields("urn:schemas:mailheader:x-receiver") = "youruser@yourdomain.com" then
Set FSO = CreateObject("Scripting.FileSystemObject")
FSO.movefile fname, replace(fname,"ucearchive","pickup")
Wscript.echo fname
end if
set msgobj = nothing
set stm = nothing
Loop

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 Graph is limited to a m

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 need to authorize it in you tenant (eg build a small ap

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 I wrote th
