# Assign an RCOS to a Mailbox

To assign an RCOS 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

1. Select(M) Modify Mailboxesto modify an existing mailbox.

   Note: Prompts are almost the same for creating a new mailbox and modifying an existing one, except that "New" precedes a prompt when you select Modify Mailboxes.

2. Press Enter until the Restriction Class of Service or New RCOS prompt appears and then enter the number of the RCOS (1 through 64) configured for the outcall capabilities for this mailbox. If you are modifying a mailbox, the RCOS you just entered replaces the existing RCOS.

1. 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.
