Exchange 5.5 and Oultook 2003

[Kelly]

I am inquiring for a list of general functions that will/will not be
available to end users when you updgrade the Client to Outlook 2003 from 2000
and leave exchange 5.5 as the server. Does anyone have any insight on what
types of issues I can expect.

There are some post Exchange 5.5 SP4 patches that you will want to apply.
These updated patches will ensure that extra properties written to the
calendar by Outlook 2003 will not cause crashes in Exchange when it comes
time to perform the online backups of the exchange or have OWA die when
accessing a calendar.

From the client side perspective...
1) Cannot connect to Exchange 5.5 via the RPC over HTTPS protocol
2) Cached Mode Exchange is there, but it is full item only (no doing headers
only or headers then item)

Other than that and IMHO, Outlook 2003 against Exchange 5.5 is pretty
uneventful.
