check whether an outlook mail contains an appointment item/request

[Bharathi]

Hi,

I am developing Add-ins for outlook 2003 using Visual Studion 2005
(C#).


My requirement is
1. Create a Tool Bar with 3 bottons "Mail","Appointment","Task".
Determine the visibility of the button based on the Type of the Item
selected in Inbox.

If I need to make "Appointment" Button visible, then I need to check
whether the selected mail contains an Appointment Request or not..

By default, all the items in the Inbox folder are MailItems. When a
particular mailItem is selected, i want to check whether that mailItem
contains an appointment request or not.

How do I determine this programmatically?

Please some one do the needful

Thanks,
Bharathi

All items in the Inbox are not mail items. You can have non-delivery
reports, task and meeting requests, post items and other sorts of items
there. Check the Class property for olMail to see if an item is really a
mail item or some other type of item listed in the OlObjectType enum.

Actually, they're not all MailItem. The value of the item's Class property is one way to check, but for C#, another approach would be to use something like this:

if (Item is Ol.MailItem)
