SUMMARY
=======

This article provides details about the registry settings that are used by the
Microsoft Exchange Server Information Store service. The information store
registry values that are noted in this article are present by default after you
successfully set up Exchange Server 5.5.

When you run Exchange Performance Optimizer, some of these default values may
change, depending on the options that you choose. When you run the "perfwiz -v"
(without quotation marks) command from a command prompt at the \Exchsrvr\Bin
folder, you can modify these default values. If you manually specify a value
that is outside of the minimum or maximum value, the minimum or maximum value is
used, respectively. When you use the "perfwiz -r" command, you can open
Performance Optimizer in read-only mode to view the current settings. This does
not stop Exchange Services.
