This article covers how student employees, staff, and faculty can access a shared mailbox in Office 365, Outlook (Windows and Mac), and Apple Mail.  With a shared mailbox, users with access can view the content and send messages from its email address. Resource numbers can be found by searching the email address or display name in the Global Address Book on Outlook (top right of the dashboard).  Select the Global Address List to search rather than the Offline Global Address List. 


If you cannot access your shared resource, you should ensure that you have proper access to the resource. You can confirm or request access by contacting the Technology Support Center.  The mailbox will be added to your current UConn account and not accessed through the email address directly with a separate password.
