what is exchange store?

[Microsoft LiveComm Develo]

Hello All,
I wanted to know what exactly is an exchange store in exchange server 2003?
The way I know it is as a repository(store) where all the information of the
exchange server is stored. It is at a location that can be specified by some
URL. You can query the store to know information like the schedule of a
person or accessing somebody's mailbox information.

Please tell me whether I am right or not.

The other thing that I wanted to know was - There are events and event sinks
in exchange server. One of the system events is OnMDBStartUp and
OnMDBShutDown - when are they exactly generated? Are they generated when the
exchange server starts or shuts down or they are related to the exchange
store? I wanted to use these events and was wondering whether I can use them
for detecting startup and shutdown of exchange server.....

Thanks for any kind of help.
Best Regards,
Purvi

You might want to have a read of the Exchange Server 2003 Technical
Reference Guide
http://www.microsoft.com/downloads/d...displaylang=en
its the best online reference to the architecture of Exchange. Tony
Redmond's book also does a very good job of explaining this. (It's lot more
complicated then just a simple database store, The under-lying structure of
the Exchange databases are undocumented)

If your looking at it from a programmatic perspective the method you use to
access particular items will differ for each API. Eg if you use Exoledb/ADO,
WebDAV or CDOEX then every item within each mailbox or pubic folder store is
accessible via a file or http URI, you can also search the Exchange Store
(with some limitations) with SQL commands via these API's.

OnMDBStartUp is explained in the Exchange SDK which you can download from
http://msdn.microsoft.com/exchange but it essentially fires when each
exchange mailbox or public folder store is mounted or dismounted. These are
completely independent of the rest of Exchange as you can have multiple
mailbox/Public folder stores on Exchange with some mounted and some
dismounted. If you looking at firing an event on the server start-up and
shutdown you maybe better of using WMI and fire it when one of the Exchange
services (eg the information store) start-ups or shutdowns eg
http://www.microsoft.com/resources/d..._wmi_kzcp.mspx
or have a look at SVCMON from the Server Resource kit.

Hello Glen,
I am facing one more problem. I have written an event sink to test the
OnSave event on Exchange Server.
My observation is that the exchange server raises this event when an email
is received by the client on whose store the event has been registered.
But I want to handle the situation where any appointment saved to the
client's calendar generates an event.

Can you explain why this is happening? My general understanding of OnSave
events tells me that it should be raised even when an appointment is
scheduled to the user's calendar.

Thank you very much for your help.

Hey Glen,
I have a new problem with the exchange server.
The OnSave event on the Exchange Server is raised only in cases of an email
receipt. It is not generated when an appointment is saved to the calendar.

I want to capture the condition where an appointment is saved/modified to
the calendar.

Can you throw some light on this?

Thanking you in advance.

OnSave will fire for a calendar appointment, it fires when any item is saved
to the store. If you want an event sink to fire when you create or save
calendar items then you need to make sure you register this event sink on
the calendar folder. The only two folders that an event sink wont fire on is
sent items and the outbox

Thank you very much Glen...

I registered the OnSave event on the calendar folder and it works perfectly
fine... Thank you very much.

The script that I was using, used to register OnSave event on
file://./backofficestorage/PresenceServer1.com/MBX/purvi/testeventReg.eml

so if I register an event on the parent folder MBX/user, wouldn't it be able
to trap events on all the folders namely inbox, calendar.....

I just wanted to make my fundamentals clear about Exchange Server.....

Thank you very much Glen.... You have been a great help.

It depends what scope you set when you register your event sink, if you
register a sink and set the scope to deep then it recursively traverses
subfolders have a look at
http://msdn.microsoft.com/library/en...r_eventreg.asp
