  5. Click the Back button at the window prompting you to type the password for the shared mailbox email address. Do not enter a password here as you will use your own credentials for authentication (as described in #6) .

     

     

  6. Edit the username to match your own 8-character username@uwaterloo.ca* (i.e. myuserna@uwaterloo.ca), then click the Next button.
    *Be sure to use your own username@uwaterloo.ca and not a friendly email address.

  8. Complete the DUO 2-Factor Authentication.

     

     

  9. Click the Done button.

10.  Quit/close the Outlook app and then relaunch to access the mailbox.

 

The new mailbox will display at the bottom of the folder list in Outlook

 

 

Notes:

  • The mailbox folders and contents can take an hour or two to appear if your permission to access the shared mailbox was added on the same day when you add the shared mailbox to Outlook.

  • Sent messages from this shared mailbox will be saved in the Shared Mailboxes' Sent folder
