"First startup experience Immediately after you install the SP2 update, the
first startup of Outlook will not be fast because Outlook must update
internal PST data structures that are used in SP2 performance optimizations.
This is a one-time occurrence that affects only the initial startup. The
upgrade process may take from several minutes to two hours. The time depends
on how large your PST and OST files are and on how many PST files are mounted
in the profile during the first startup. As soon as the data structures are
updated, Outlook will benefit from the improvements. "
