I tried doing some digging, and am curious... Are there any online
references to Exchange 2007 "eventing"?

This is likely an API, but I can't seem to come up with any search
results...

Powershell wont really help with this one you'll need to use one of the
Exchange API's to do this there are a few options

1. You could write a Transport Agent and change the message while its in the
transport Pipeline the message class is a bit of a special property but you
can change it using the TNEF writer see
http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=1381211&SiteID=17 .
Using the TNEF writer isn't the easiest thing in the world but this is the
method that i would recommend using.

2. You could write a Notification application using Exchange Web Services
basically you subscribe to the new mail notifications in the Folder and then
your application connects back to the Mailbox and can change the item in
question. The problem you have here is that notifications are Asynchronous
so you will receive the notification after the mail has arrived. Your
notification app is just another client in this instance so there's no
guarantee that it will get to the message first before any of the other
clients you have connecting to the mailbox.

3. You could write a Exoledb Event Sink. Exchange Store Events sinks have
been deemphasised in 2007 (so probably wont be their in the next version)
but they are still fully functional. eg you can create a onsyncsave event
sink and register it on the inbox of the mailbox in question and it can be
used to change the message class.

All the information you need is in the Exchange SDK which you can grab from
http://msdn.microsoft.com/exchange

Thanks for the detailed reponse. However I did notice a PowerShell
cmdlet that *might* help.

I'm not familiar enough with Exchange... The cmdlet
new-managedcontentsettings has a messageclass parameter:

"-MessageClass
The MessageClass parameter specifies the message type to which any
expi ration and journaling configuration settings within these content
settings apply.
The parameter value can be a well-known message type such as
Calendar I tems or a specific message class such as IPM.NOTE.SMIME.
Well-known message types are as follows:
* All Mailbox Content
* Calendar Items
* Contacts
* Documents
* Faxes
* Journal items
* Meeting Requests, Responses, and Cancellations
* Notes
* Posts
* RSS Items
* Tasks
* Voicemail
Specific settings supersede general settings. For example, Voice
Mail supersedes All Mailbox Content."

I wasn't able to figure out exactly how to use it. Primarily, how to
have it reference a public folder.

I'll keep searching in my spare time...

No that wont help this just controls journaling and expiration on Managed
folders this wont affect the actually content. At the end of the day you
have mail coming into an inbox there is no configuration you can change that
will change the message class. You have the force the change via one of the
Exchange API's or just have the source that sends the mail set it in the
first place.

One last option I've just thought of and probably the easiest to implement
because it doesn't require you to code anything and its something you could
use from a script is to use a Server side rule on the inbox in question.
There is an option with rules to set a Mapi property you can do this with
the rule.dll and cdo 1.2 in VBS (it wont work in powershell because of the
way CDO 1.2 threads) or you could use RDO from Redemption which will work
fine from Powershell. Its look like Dmitry has already got a sample there to
do what you want have a look at
http://www.dimastr.com/redemption/rdo/rdorule.htm (this sample in the tag
property)

Any references to this "CDO 1.2 threading issue"? It have to do with
the ApartmentState?

I dont remember the full details but just try using it and you'll find out,
CDO 1.2 has never been supported in .NET
http://support.microsoft.com/kb/813349 if you want to use CDO its a much
better idea to use VBS. Your basically only using the script to create the
rules anyway.
