Google worked with Microsoft to patch up some serious issues with the first version of the Outlook plugin for Google Apps. Among other things, the first version of this plugin disabled windows desktop search, which probably made Microsoft as angry as most users.
The new version finally plays nice with things like Windows Desktop Search, and some other Outlook plugins that the first version conflicted with. This quick fix is surely appreciated by people who were affected by some of the problems in the first one.
Your Outlook plugin will update automatically with the new version -- but if you dont' have it already, you can find it here.
