Go to email.uconn.edu and click on the orange Office 365 button.
Log into your own mailbox using the appropriate credentials (email address and NetID password for faculty/staff or student work account and corresponding password for student employees).
Select Outlook.
Right-click Folders just above the inbox and select Add shared folder or mailbox.
In the window that appears, enter the name of the mailbox or the NetID of the user who is sharing with you.
