During installation, the Office Setup Assistant creates a contact entry that contains information, such as your name and address, that Office for Mac 2011 applications use. For example, when you make changes to a document that has tracked changes turned on, Word uses the information to label the changes with your contact information. If you want, you can edit the contact entry that represents you.
At the bottom of the navigation pane, click Contacts .
On the Organize tab, click Me.
Make the changes that you want, and then click Save & Close.
Note: The contact that represents you is always saved on your computer and can't be saved to a Microsoft Exchange account.
