Avaya Modular Messaging Concepts and 

Planning Guide

MSS does not have access to messages that were sent to the subscriber’s 
mailbox on a separate corporate e-mail server. To manage attributes for 
Avaya Modular Messaging subscribers and Modular Messaging system 
data, the MSS uses an LDAP directory service.

The Avaya MSS is available in two configurations: 

!

Avaya MSS—S, the standard-availability configuration 

!

Avaya MSS—H, the high-availability configuration 

For information on the capacities of the Avaya MSS—S and MSS—H, 
see 

 on page 11-4.

For increased security, performance, control, and application 
management, the Avaya MSS is connected to the messaging application 
server (MAS) by means of a private Ethernet LAN.

An Avaya Message Storage Server (MSS) is designed such that it has no 
administratively activated offline mode.

Avaya Modular Messaging supports the Microsoft Exchange Server 2003, 
Microsoft Exchange 2000 server, and Microsoft Exchange 5.5 server. For 
each Modular Messaging subscriber, the Microsoft Exchange server 
provides a single message store that holds all messages—voice, text, 
corporate e-mail, and fax—that the subscriber receives. To manage 
attributes for Avaya Modular Messaging subscribers and MAS units, 
Microsoft Exchange server, except for Microsoft Exchange 5.5 server, 
uses Active Directory.

Note: New installations of Modular Messaging do not support 

Microsoft Exchange 5.5 server. 

For each Modular Messaging subscriber, the IBM Lotus Domino server 
provides a single message store that holds all messages—voice, text, 
corporate e-mail, and fax—that the subscriber receives. To manage 
attributes for Avaya Modular Messaging subscribers and MAS units, 
Domino uses the Domino Directory. 

Avaya Modular Messaging—IBM Lotus Domino version supports the 
IBM Lotus Domino Server 6.5, IBM Lotus Domino Server 6.0, and IBM 
Lotus Domino Server 5.0.10.
