View PowerPoint slides more effectively in iPhone Mail

Apple recently released a support document that explains why Microsoft PowerPoint slides appear blank with a white background or fail to render properly in the iPhone and iPod Touch Mail app.

The problem is a caused when documents, which are subject to display size limitations, are converted to HTML Web pages before being displayed on the iPhone or iPod. Large images or multiple medium-size images used on a PowerPoint slide result in some not being visible in the converted content.

It is important to give the slides time to render before giving up, because some slides take longer to convert. If you feel you've waited long enough and the slide still does not render properly, Apple offers the following suggestions:

• Reduce the size of images in any of the slides that failed to render properly and resend to the iPhone or iPod.
• Convert the PowerPoint file to PDF and resend.
• View the PowerPoint on your computer using MS Office or Quick Look on Mac OS X v10.5 or later.
