    | INCOMING MAILBOX | 
     
      | Order: |  | Indicates the order for retrieving incoming mailbox 
          messages for a subscriber: 
          
             fifofirst in, first 
              out lifolast in, first 
              out | 
     
      | Category Order: | The following three letters in any order: | Indicates the order for scanning the incoming mailbox message categories for a subscriber. 
           n = New. Neither the header 
            nor the message body has been read. u = Unopened. The header 
            has been read but not the message body. o = Old. The header and 
            the message body have both been read. The order oun encourages subscribers to keep messages stored to a minimum by forcing them to scan through old messages first. | 
     
      | Retention Times, (New, Old, and Unopened): | 
   A number from 0 to 999 Default=10 | Indicates the number of days that new, old, and unopened messages are retained in the incoming mailbox for a subscriber. After the specified period of days, the system deletes the messages. The retention time clock is not reset to zero (0) 
          when a message is moved among the old, unopened, and new categories. 
          For example, if the retention time is 10 days for all three categories, 
          a message is removed after 10 days (not 30 days) regardless of whether 
          or when it is moved from one category to another. | 
  
    | OUTGOING MAILBOX | 
     
      | Order: |  | Indicates the order for retrieving messages from the outgoing mailbox for a subscriber.

      | Voice Mail Message (Seconds), Minimum Needed: |  | The minimum mailbox space needed (in seconds) to 
          create a voice or fax mail message. If fewer than the minimum number

      | Call Answer Message (Seconds), Minimum Needed: | 
   A number from 0 to 1200 Default=8  | Indicates the minimum mailbox space needed to leave a call-answer message for a subscriber. If less than the minimum number of seconds remain in a subscriber's mailbox, a caller hears the "full mailbox" greeting. |

          message capacities to the larger of: 
           Double voice-only capacities to allow for both 
            voice and fax messages. For example, change Maximum Message Lengths 
            of 700 seconds to 1400 seconds. At least 20 minutes of capacity to allow for 
            both voice and fax messages. In this case, enter Maximum Message Lengths 
            of 1200 seconds. | 
   0 (zero) A number from 15 to 60 | Enter the number of seconds that a warning message plays to indicates the remaining available recording time. The system plays the warning message this number of seconds before the maximum recording time is reached. If you enter a 0 (zero), no end-of-message warning is played.
