So then, you’re one of the lucky/unlucky ones (delete as applicable) and have a shiny new copy of Office 2007 on your desktop - the envy of the office no doubt… until you try to send them a PPT file. Of course they can’t open it - nor can the client you’ve just sent it to either. Two phone calls / emails (delete as applicable) in the space of 5 mins as they anxiously try to get into your fine presentation work.
You could of course send them to the PowerPoint convert zone right here on this site… or you could get smart and set your application up correctly… just like this in fact:
For Word 2007, Excel 2007 and PowerPoint 2007, if you use the following technique as soon as you install the Office 2007 software, you will ensure you never get that frustrated colleague on the phone.
Step 1: Click on ‘POWERPOINT OPTIONS’

PowerPoint 2007 options screen
Step 2: Select ‘SAVE’ from the sidebar.
Step 3: Select the top drop down - ‘Save files in this format’ and select ‘PowerPoint Presentation 97-2003′.

As an optional extra - another really useful box to check is the ‘Embed fonts in the file’ box. In Office 2007 there are a number of extra fonts included - Calibri being one, which are not included in Office 2003 and earlier. If you have been building a presentation in Office 2007 using Calibri and send it on to a colleague with Office 2003, it will not look as expected, as they do not have the font. Selecting this box will make the file a little larger, however it will ensure the presentation reads correctly.
Step 4: Select OK.
Point to note - when saving PowerPoint 2007 files (.pptx) down to PowerPoint 2003 (.ppt) there would be a minor loss of fidelity if you’ve used advanced features in the file - for example Smart Art. The file will look correct, however users of PowerPoint 2003 will not be able to edit that particular slide using the Smart Art functionality.
I’ve used this ’save down’ feature for about 18 months now - and it’s never caused a problem yet! Compare that with the number of times around the office have I heard frustrated Business PowerPoint colleagues with file version problems!
Being Smarter - it’s the name of the game.
