Shared Mailboxes (CSULB Email)


Also known as a shared account, a shared mailbox is an individual email account that is usually shared among several people.  The purpose of a shared mailbox is to provide a central email account for a specific business purpose, often with the intent of several people being able to access and manage the account. When a person in the group replies to a message sent to the shared mailbox, the reply appears to come from the shared address, not from the individual person. You can also use the shared mailbox as a shared team calendar.

This article provides information about how to access Microsoft Exchange shared mailboxes after it has been created and you are given the access.
