One of the cool new features in Office Mobile 2010 is the Presentation Companion for PowerPoint. To get this to work, first you need a Windows Mobile 6.5 device with the Microsoft Bluetooth stack. Then you can download and install the beta of Office Mobile 2010 from the Windows Mobile Marketplace. You also need a desktop/laptop computer with Bluetooth that also has PowerPoint 2007/2010 installed. Then you need to install the Presentation Companion plug-in for PowerPoint on the desktop.
After you get all that done, you need to have the same PPT file on both your PC and your Windows Phone… both opened in PowerPoint. Next go to the Add-ins tab in PowerPoint on your desktop and “Start” the Presentation Companion. Then on the Windows Phone, choose Menu>Presentation Companion and follow the instructions for connecting to your desktop installation of PowerPoint via Bluetooth.
After all of that is done, you’ll be able to see your PowerPoint notes on your Windows Phone, while being able to control the slide presentation on the desktop via Bluetooth.
There are 2 “Gotchas” to be aware of.
1. The Presentation Companion beta software does not work on 64bit versions of PowerPoint.
2. The mobile side of the Presentation Companion does not work with non-standard Bluetooth software implementations on Windows Phones such as the HTC Touch Pro2 or HD2.
