3.3 Shared Voice Mailbox


If several employees are sharing a campus phone, a shared mailbox allows each person to access and manage only their own messages.

How It Works

Leaving Messages

When a caller reaches voice mail for an extension with a shared mailbox, they will hear a prompt saying "For user A press 1, for user B press 2," etc. After the caller selects from the menu, they will be able to leave a message for the user they have chosen.

Retrieving and Managing Messages

Once a shared mailbox receives a new message, the phone's message waiting light will turn on (or for analog lines, users will hear broken dial tone). When a user dials into voice mail to check their messages, a prompt will say "There is a message for user A. Please enter your mailbox number." Once the user logs in, they will have access to only their own messages.

Note: The phone's message waiting light will stay on as long as any of the shared mailboxes for that extension have unread messages.

Requesting a Shared Mailbox

Visit the Voice Mail service page and click the "Request Service" button to request work order for a shared mailbox for an extension. Include the phone extension and the full names of all users that share the line. If there is a preference, also indicate which user should be assigned the "primary" number, which is described in #1 below. ITS will notify the requestor when the shared mailbox is ready for use.


There are no one-time or recurring charges for requesting a shared mailbox.

Additional Details

  1. Although we use the term shared mailbox, it is actually multiple separate mailboxes which can be accessed through one phone extension. There will be one "primary" mailbox and one or more "secondary" mailboxes.
  2. Each user of a shared mailbox will have their own unique mailbox number and security code.
  3. The phone's message waiting light will stay on as long as any user has an unread message.
  4. To avoid confusion, users can enable unified messaging which will forward their voice messages to any @csulb.edu email address.
  5. The shared mailbox setup will only work if all users have their names and personal greetings recorded.
