MAPI Exchange 2003 MAPI Exchange 2003. Type the MAPI Exchange 2003 port if you have an internal
firewall specifying a port for Exchange data. This option is not commonly changed.
NOTE: In an out-of-path deployment, if you want to optimize MAPI Exchange by
destination port. You must define fixed-target, in-path rules that specify the following
ports on the client-side HP EFS WAN Accelerator: the Microsoft end-point mapper port:
135; the HP EFS WAN Accelerator port for Exchange traffic: 7830; the HP EFS WAN
Accelerator port for Exchange Directory NSPI traffic: 7840.
MAPI Exchange 2003 Acceleration Enable MAPI Exchange 2003 Acceleration. Check this box to enable MAPI 2003
Acceleration.
This feature increases optimization of traffic between Exchange 2003 and Outlook 2003.
MAPI Transparent Pre-population Enable MAPI Transparent Pre-population. Check this box to enable transparent pre-
population.
This feature allows email data to be delivered between the Exchange server and the
client-side appliance while the Outlook client is offline. When a user logs into their
MAPI client, the mail is already waiting in the client-side appliance and can be retrieved
locally. This feature enables email to be optimized even though it has not been seen
before by the client.
Max Connections. Type the maximum number of virtual MAPI connections to the
Exchange server for Outlook clients that have shut down. Setting the maximum
connections limits the aggregate load on all Exchange servers through the configured
appliance.
You must configure the maximum connections on both the client and server-side of the
network.
Poll Interval. Set the number of minutes you want the appliance to poll for shut down
clients.
Time-out. Type the number of hours after which to time-out virtual MAPI connections.
When this threshold is reached, the virtual MAPI connection is terminated. The time-out
is enforced on a per-connection basis. The default value is 96 hours. Time-out prevents a
build up of stale or unused virtual connections over time.
Name Service Provider Interface NSPI port. If applicable, specify the NSPI port.
NSPI is the address book subcomponent of the Exchange protocol that is optimized by
the appliance. In certain situations (for example, clients connecting through a firewall),
you might want to force a server to listen on a single pre-defined port so that access to
ports can be controlled or locked down on the firewall.
