Client-side events related to out-of-office?

[vklrc]

Hi. I suspect I know the answer, but...

I am using Outlook 2007 with Exchange Server 2003.

I am trying to write VBA code that would be able to respond whenever someone changes the Out of Office Assistant settings.

There are two ways the OOO can be changed: Via the Outlook (client) interface and via the Exchange (webmail) interface.

Is there an event that fires on the Outlook client when OOO settings are changed, especially if they are changed via the Exchange webmail interface?

Thanks!
