Desktop Firewall Applications
Firewall applications are designed to block network trafc and secure the
desktop PC from incoming network connections. Since ActiveSync utilizes
TCP ports for data transfer with Windows Mobile powered devices, you
may need to explicitly allow this trafc to be un-blocked by certain Firewall
applications. To do so, you must add ActiveSync application processes into
the Firewall programs exception list. Please refer to the documentation
provided with your specic rewall.
If you need to open ports manually in your rewall, you will need these
port numbers:
990: open inbound TCP port
999: open TCP port
5678: open TCP port
5679: open outbound UDP port
5721: open inbound TCP port
26675: open TCP port
Reconnect the device after opening these ports.
If you have a PC, which is already fully synchronised, with your Exchange
Server, then it recommended synchronising your device to your PC the very
rst time instead of synchronising to the Exchange Server. This will allow
faster synchronization.
Set up your device to synchronize with a Microsoft Exchange server
This applies only to users with access to an Exchange server. To perform the
setup for synchronization with Microsoft Exchange, you will need to get the
name of the Exchange server and the server domain name from your service
provider or system administrator. You must also know your Exchange user
name and password.
