This can be done in gmail which has introduced a new feature called 'View as slideshow". This will open your slideshow in a browser window without launching the PowerPoint application. Also the file should be sent in pps and not ppt format.
Hope this helps. Let me know if you have any questions.
Yes, gmail is indeed the term used for Google email.
You can save the presentation to pps format by either:
opening it using Powerpoint program then click File > Save As, and choose 'Powerpoint Show (*.pps) from the 'Save type as' drop down list,
just go to the file and simply rename the file by replacing the ppt extension.by pps.
Hope this helps.
Thanks. Let me know if you need further assistance.
When you open the message that has the ppt or pps presentation you will see the View As Slideshow link next to the file name, as shown in the image below.
(Note: you will see the View As Slideshow option only if there is an attachment and if the attachment is of ppt or pps type)
You're welcome. Feel free to ask if you have any other questions.
