Microsoft has responded, sort of, to Google's delivery of a free Exchange migration tool for Outlook users by trying to poke holes in the end result. More specifically, the company claims that the tool has a "bug/flaw" that causes Outlook search to stop working. Obviously, the solution is to stop using Outlook, but I'll let Google communicate that. Here's the post:

The Outlook team has recently been made aware of a serious bug / flaw with the recently announced Google Apps Sync for Microsoft Outlook, and as a result we wanted to provide the Outlook user community with additional details around this problem as well as information on how to address it.

The installation of the Google Apps Sync plugin disables Outlook’s ability to search any and all of your Outlook data. When a Google Apps user installs the sync plugin for Outlook, the plugin modifies a registry key which disables Windows Desktop Search from indexing and providing search functionality for all Outlook data, not just the Outlook data being synchronized from GMail. Because Outlook search relies upon the indexing performed by Windows Desktop Search, Outlook search functions are broken as a result. It is also important to note that uninstalling the plugin may not fix the issue.

The presentation of this information is eerily reminiscent of the "Windows Secrets" newsletter (not to be confused with the "Windows Vista Secrets" books). At least Microsoft provides a solution.
