Adding a shared mailbox to Outlook for Windows - Instructions for M365 Shared Mailboxes

These instructions are for users who use Microsoft 365 (M365) for their personal email.
The instructions for users whose email account is an on-prem Connect account are available: https://uwaterloo.atlassian.net/wiki/spaces/ISTKB/pages/1854013815

To add a shared mailbox it is necessary to have all of the following:

  • “Send-as” and/or full access permissions to all folders of the shared mailbox

  • Your own username requires permission to the shared mailbox. You will login using your own credentials. (Your department IT support can help you request access.)

  • Permissions on Windows Nexus computers become effective the next time you log onto the machine after the mailbox permission change has been made. You may need to log out from your Nexus account on the machine and then log in again to add the account and access the mailbox.

Contact IST Service Desk if your account does not meet the above requirements.
