# Assign a GCOS to a Mailbox

Before you can assign a bitmapped GCOS, you must define its parameters.

To assign a bitmapped or affinity group GCOS to a mailbox configuration.

1. From the Main Menu, select (M) Mailbox Maintenance.

2. Select (C) Create New Mailboxes and enter the number of the new mailbox you want to configure.

   OR

3. Select (M) Modify Mailboxes and enter a mailbox number to modify an existing mailbox.

4. Press Enter until the Group Class of Service or New GCOS prompt appears and then enter number of the bitmapped GCOS (1-64) or affinity group GCOS (65-32,000) that governs this mailbox. (If you are modifying a mailbox, the GCOS you just entered replaces the existing GCOS.)

5. Press Enter to skip through each of the remaining mailbox configuration prompts. After the last prompt, the server displays the mailbox configuration, then prompts for the next mailbox number.

At this point, the parameter settings are saved and you can continue with mailbox configuration or exit.
