For administrators of Microsoft Mail (PC), the following list of familiar terms and how they relate to Microsoft Exchange Server terms should help you understand differences between the two products:
|MS Mail for PC Networks term||MS Exchange Server equivalent term||Descriptions|
MS Mail Connector MTA
The MTA is a integral part of the server and moves mail by talking with MTAs at other servers.
The MS Mail Connector MTA can move mail between MS Mail PC postoffices. It also moves mail between MS Mail PC postoffices and the MS Mail Connector postoffice.
|Windows Remote client||Windows client||All MS Exchange clients are remote clients. They need to have network connectivity to send and read mail.|
|Postoffice||Server||Postoffices are a collection of files. The server is an active process.|
|Directory synchronization||Directory replication||Replication occurs as needed within a site and between sites.|
|Directory synchronization server||Directory bridgehead servers||
Replication is a peer-to-peer process within a site. Changes are sent to all servers, not to a central server.
Between sites, directory bridgehead servers package up changes and forward them to other sites.
|Downstream postoffices||Address space and Connected Sites property page.||When you add a new gateway to a site, configuration is done for the site, not per server. In other sites, you need to change the address space so mail to the gateway is routed to the site the gateway is installed into. This is related to the connected sites property.|
|Access component||Not applicable||See "Downstream postoffice" for more details.|
|Import.exe||Directory import and export||Close match of features|
|Postoffice address list||Site-server-recipients||Custom recipients do not need to be added to server recipient lists to be included in distribution lists.|
|Postoffice groups||Distribution lists (DLs)||DLs are created once per organization, not per postoffice. DLs are expanded to include all members. Membership in a DL is not limited to mailboxes and custom recipients - it includes public folders and distribution lists.|
|Modem scripts||Not applicable||Remote clients connect with RAS, Shiva or other remote access network software. Modem scripts are no longer needed for remote client access.|
|Shared folders||Public folders||Public folders are visible throughout the site. With site affinity, they can be accessible from other sites.|
|Group folders||Public folders||Public folders are visible throughout the site. Permissions can be assigned to any recipients.|
|Custom message||Form||Forms are easier to create and use. They no longer require changes to INI files, and are installed in folders or sites.|
|MSMAIL.INI||EXCHNG.INI or registry entries|| |
|SHARED.INI||Enterprise forms registry||Adding a custom form to the enterprise forms registry makes it available to all Windows clients in the site.|
|Custom command||EXCHNG.INI or registry entries|| |
|Custom menus||EXCHNG.INI or registry entries|| |
|FOLDCOMP.EXE||Automatic background task or offline.||The private and public information stores repack the data file to move unused space to the end of the file. Offline compaction reduces the size of the file.|
|MOVEUSER.EXE||Administrator program||Within a site, updating of distribution lists, and permissions on public folders is automatic. Between sites, or into different recipient containers, see the procedure in Microsoft Exchange Server Maintenance and Troubleshooting.|
|LMEXT.EXE||Administrator program||The file is created in the directory import format.|
|NOVEXT.EXE||Administrator program||The file is created in the directory import format.|
|TEMPLATE.EXE||Directory Import and Export in the Administrator program||Modifies more than template information - can also change distribution list members, display name and other properties of a recipient.|
|Gateway||Connector||Connectors are administered with the Administrator program, and run as Windows NT services on the server.|
|Mail Message File (MMF)||Personal Folders (PST)||Personal folders are only required for offline use or when not using the Microsoft Exchange Server information store.|
