Supports access to Microsoft Exchange Server table objects, specifically system access control list (SACL) table objects and rule table objects on Microsoft Exchange Server folders. This interface resembles the IMAPITable : IUnknown interface, but it adds support for Microsoft Exchange Server-specific structures that are used to control SACLs and rules.
To obtain the IExchangeModifyTable interface, call the MAPI IMAPIProp::OpenProperty method on a property of type PT_OBJECT on a folder object. When you call the OpenProperty method, pass the value IID_IExchangeModifyTable in the lpiid parameter.
