I think that you should not use VSS instead of a regular back up for Exchange.
VSS provides and interface for the Software Vendors. They can use that interface in the backup software solutions which you purchase from them.
Technically speaking you can configure VSS for the volumes where the exchange data resides. The problem is that the VSS is enabled on a per volume basis which means that if your Exchange logs are on “D volume” and database files on “E volume” you have to enable VSS on both volumes. You can schedule the VSS and configure disk space restrictions but what is the point of such an approach?
•      The data created by VSS is stored on the same volume and in case of a disk failure you will lose it.
•      If you need to restore quickly a deleted email again that is definitely not a wise approach. It is much easier and faster to configure a Mail Retention policy like in the following video (screencast):
