Shared workbook auto save macro

[ITWater]

Hi

I'm sharing a workbook from a server where the file resides to 10+ workstations.

I am a novice using code, can anyone suggest a method to ensure that the workstations with the file open auto save every 10 minutes to ensure every user has an up to date picture of the workbook.

This workbook is shared using the share function within excel.

Help!!!!
