“New Outlook” is a new version of Outlook for Mac with a redesigned interface.

To open a shared mailbox you have been granted permissions to access, first open Outlook

Select File > Open > Shared Mailbox

Search for the name of your mailbox and a list of similar names will appear, highlight your shared mailbox and click Add

The shared mailbox will then be added below your primary mailbox

 

Alternative method:

In the Tools menu select Accounts and select your own email account

 

Select Delegation and Sharing

 

Choose Shared With Me tab

Choose + to add the mailbox

 

Search for your mailbox and select Add

 

If upon following these steps you encounter an error saying: “Cannot open this mailbox - this mailbox has already been added”, press Cmd+Q to quit Outlook, then re-open it.

 

 

 

 

 

 

 

 

 

 

 

 

If you are still not able to open the mailbox it is likely you don’t have permissions; please ask someone with existing permissions to apply on your behalf to the CSCS Service Desk.
