# Assign an LCOS to a Mailbox

Note: Before a custom LCOS can take effect, you must define it.

To assign an LCOS 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 Limits Class of Service or New LCOS prompt appears and then enter the number of the LCOS that will govern this mailbox. (If you are modifying a mailbox, the LCOS you just entered replaces the existing LCOS.)

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.
