A shared workbook needs to reside on a shared drive in order forothers to collaborate on it. When a shared workbook is edited and thensaved, users connected to the same workbook will see the changesautomatically. If you created the workbook, then youcan control the user access as the owner of the workbook and have theoption to stop sharing the workbook at any time.
Please note that certain functionality is not available after theworkbook becomes a shared workbook, so it is best to make sure that allformatting is complete prior to sharing it.
