How To: Set Up Office365 Outlook Resource Mailbox as an Add-on Account

These instructions provide help on adding a shared resource mailbox to an account already set up within Outlook.

If you do not have an Outlook account, such as if you are a student worker, then please visit this page for information on how to set up a shared resource mailbox as a primary account.


1] Access to Share Mailbox
Your NetID must first be granted access to the resource account in order to access it. If you do not already have access then CLAS departments can contact Robert Dowden for granting them access. After being granted access please log off and log back onto the computer for the changes to take effect for the account.

2] File Menu
From within Outlook click on File from the upper-left corner.
