Remarks
This cmdlet is used to compare one object's values with another.When working with items in mailboxes, there are times when one would like to know the effect of an action on an item.  Using this cmdlet, one can get 2 instances of the same object, one before the change, and one after and compare the differences.For example, if one wanted to know what attributes change when a message changes from Unread to Read, Compare-MapiProps could show which values of the message changed.
