When accessing a shared mailbox via Office 365, you will need to follow this process each time you login. See the instructions for configuring a shared mailbox for Outlook (PC or Mac) or iOS devices to have the shared mailbox configured for repetitive access.
Students still using Gmail are able to access shared mailboxes as well, but only if they have been added to the group that has rights to the mailbox. To access, the student should go to https://outlook.office365.com/mail/nameofmailbox@elon.edu/ and login using their Elon University credentials
1.) Log into your email account at email.elon.edu
2.) Click the photo icon in the upper right-hand corner (it may be blank, as shown below)

3.) Select 'Open another mailbox...' from the drop-down list

4.) Enter the name of the shared mailbox (1) and click 'Search directory' (2)

5.) Click 'Open'

Your shared mailbox will now open as another tab in your web browser. Remember, if you want to send emails from your normal account, you will need to switch tabs back to your own email inbox.
