MAPI status

This property indicates which of the methods in a status object's implementation of IMAPIStatus are supported. Status objects are allowed to return MAPI_E_NO_SUPPORT from unsupported methods.

Clients use a status object's PR_RESOURCE_METHODS property to avoid making calls to unsupported methods. If the flag that corresponds to a particular method is set, the method exists and can be called. If that flag is clear, the method should not be called.

The status objects implemented by MAPI support the following methods:
