If you add or make a change to a hyperlink setting in a large Microsoft PowerPoint presentation, the changes that you made are not retained when you reopen the file.
PowerPoint stores the hyperlink information in the Document Summary storage area of the presentation. This storage area has a limit of 64 KB. The Document Summary storage contains all the document properties, custom properties, references, and other similar data.
Because the Document Summary storage is used by different aspects of the presentation, there is a finite number of hyperlinks that can be stored in presentation. This is compounded by the fact that the longer the text is for a hyperlink that you have to store, the fewer you can store.
Theoretically you can store upward of 32 KB of characters in the Document Summary, which translates to approximately 6,500 words. More than half of this is already allocated to dedicated Document Summary items. After the free space is used, no more can be allocated to the presentation.
For hyperlinks that you create to other slides, slide titles, or a custom show within a presentation, Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
For hyperlinks that you create to sites external to the presentation, this problem no longer occurs in PowerPoint 2002 or PowerPoint 2003.
