Hello,

My company offers a web portal where our clients find all kind of usefull
information and services, between those services we offer web mail based on
Exchange 2003.

In the home page of the portal we show the mail used quota % and the number
of unread messages (from this home page, the users can link to the OWA
aplication if they want to).

So far we are using Webdav and we have tested WMI to retrieve this info,
both technologies are too slow for our needs (we receive mora than 30
requests per second) and Webdav takes almost 0.15 seconds to get the info.

Is there any way to achieve this functionality (retrieve used quota and
number of unread messages) using Extended Mapi? I guess it will be much
faster. We have never used this technology and even though we found some
examples over the internet we were not capable of making it work.

Has anyone done a similiar work?

Thanks,

Carles

I forgot to mention that we are considering the possibility to subscribe to
the OnSave and OnDelete Event Sinks for Exchange. The event handler would
compute the quota and unread messages and store the info in a table in our
main application SQL server.

Our doubt is how to subscribe to all the folders of the storage group.
Subscriptions seem to be at a mailbox level.

We could write a script to subscribe to all the folders in the storage
group but that doesn't seem very smart.

Any advice?

Hello,

store events are bound to a mailbox unless you bind it to the
system-mailbox. In this case it fires for all messages in a particular
store.

But this event is not triggered for changes of the read-flag.

What language are you using? If you are using .NET, then MAPI is not a
suitable way - it's not supported from a .NET context.

Best regards,
Henning Krause

Thanks Henning,

We use C# for our main application, in any case, we have no problem on
developing some modules in C++.

We will test your suggestion about using the System-mailbox.

Thanks,

Carles
