# Assign an FCOS to a Mailbox

The steps below assume you have already chosen the default FCOS desired or have already customized an FCOS.

To assign an FCOS to a new or existing mailbox:

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

Select (M) Modify Mailboxes to 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.

3. Press Enter until the Feature Class of Service or New FCOS prompt appears.

4. Enter the number (1-640) of the FCOS that will govern this mailbox. The default value is 1. Press ? for a list of defined FCOS. If you are modifying a mailbox, the FCOS you just entered replaces the existing FCOS.

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.
