For some reason, the Blackberry Desktop software wasn't showing Microsoft Outlook as one of the PIMs to synchronize with. I tried versions 4.3 4.5 and 4.6, with identical results. Intellisync's configuration wizard would appear, and you'd see the Contacts, Calendar and other options. When you click Setup..., a dialog box would open and you'd see only Yahoo mail and Text file exporters.

The solution was to install the software using the "Work Email Address" setting, which is designed to be used with Blackberry Enterprise Services. Do this even if you don't have BES. During the setup, select BES for MS Exchange.

Make sure that MS Outlook is set as your default mail and address book provider. This is in the Control Panel's Internet Options, under the Programs tab.

For some reason, this will cause everything to work. Everything should default to syncing with MS Outlook.

It will also cause Blackbery Desktop Redirector to also start up. This may or may not cause problems. It's hard to tell.

Also, for some other odd reason, this solution isn't presented on the forums, but was found on a Zimbra website.
