Upgrading from Microsoft Exchange Server Version 5.0

The Microsoft Exchange Server version 5.5 upgrade includes a more robust Outlook Web Access interface.

Backing Up Web Connector Files

Setup backs up your existing Web Connector files in case you have made significant changes to them after they were installed. The backup directory is Webdata\<Lang> <5.5>.tmp, where Lang is the language your server uses, and 5.5 is a number that increases each time you upgrade.
