Office 365, Outlook for Windows, Add shared mailbox

Offices often have at least one shared mailbox for voice mail, responding to outside inquiries, projects, and more. Follow the steps below to add a second account to Outlook 365 on a Windows computer.

NOTE: this feature is no longer available in Office 365 for Mac. To open a shared mailbox on a Mac, you will need to use Outlook Online.
