First, to gain access to a shared email box, send a request to IT or have your manager send a request!

If you use Outlook from the web:

1.) Select  the profile button in the upper right hand corner.

2.) Select "Open another mailbox".

3.) Type in the email address you have been granted access to, and select "Open".

If you use Outlook for desktop:

The email will automatically populate as a dropdown below your own email folders!

If it's not visible, you may need to scroll down, or use the arrows to collapse your inbox. Else, if it's been less than 10 minutes since you were granted access, please try again in a bit!
