Using Outlook and Exchange Offline

If you use Outlook 2003 primarily on one computer, at the office, this chapter is probably not for you. However, a large number of people use Outlook 2003 in multiple locations, such as the office, home, in a hotel, or even on a cruise ship (yes, I've actually used Outlook on a cruise ship). If you travel for business, you might take a laptop with you when you travel and establish a connection to your corporate network from wherever you happen to be that day.

When traveling out of the office, you need a method to connect Outlook to your corporate Exchange Server. You can use Outlook when out of the office in several ways:

• Using offline access to Exchange

• Using Cached Exchange mode

• Using Remote Mail

• Using RPC (Remote Procedure Calls) over an HTTP connection

This chapter will cover each of these options in detail.
