Do you know how to compress your PowerPoint, e.g. from 26MB to 13MB?

Unfortunately, when you “Send As Email” it doesn’t compress the file; this is how to compress a PowerPoint for emailing.

Remove the video from the master slide.

This has been done in the 3.8 release of the template, but for old templates you may have to do this manually.

Figure: Go to the slide master

Figure: Find the slide layout "Presentation with Title and Video" and delete it

Compress ALL your images

Figure: Go to the File menu

Figure: Select Options

Figure: Apply settings. You may compress this further down to 96ppi if you must

Compress individual images (not recommended)

Figure: Find the Image Compression option

Figure: Apply these settings and go for a coffee break. This may take a long time, depending on how many slides you have

Compress font - ONLY DO THIS WHEN YOU ARE FINISHED EDITING

Figure: Apply these settings. Once you remove the font, you’re more likely to get missing font bugs when editing the file, so only do this step when you are done

Save as "YourFileName_compressed.pptx."

Do not override your original. You should always keep a high-res master of any media document.

If you find your files are still rather big after compression, you can export the PowerPoint to determine which particular slide is taking up all that space. http://www.addictivetips.com/windows-tips/find-which-slide-in-your-powerpoint-presentation-is-the-largest-in-size/
