How Do I access a shared calendar/contacts/tasks in Outlook Web Access (OWA)?
1) Log-into Outlook Web Access.
2) To view a calendar, from your inbox, enter “/USERNAME/calendar” (without the quotes) in the Address bar. USERNAME is the person’s calendar who you are trying to open.
3) The user must give your rights to view a shared resource, otherwise Outlook Web Access will log you off. If this happens, click on Home and click on Outlook Web Access in order to log back in.
