These instructions help you allow other MSU team members and Spartans to see more information -- than just free or busy -- about your Spartan Mail calendar events. You can set an overall default permission for all Spartans to see or add individuals and designate special access for them.
If you choose to change these settings, be sure to mark individual meetings or appointments as "private" if they should not be viewable by others.
Instructions vary slightly depending on the version of Outlook you are using.
