Create a Public Folder on Office 365 Exchange Online and add it to Outlook Web App or a local Outlook

An Exchange public folder can be used by several people in Outlook Web App or in their local Outlook installations. It allows a group of users to view and send e-mails from a common mailbox. These users can also share a common calendar.

 

A public folder must be contained in a public folder mailbox.
