A. No. The targets for LCR, CCR, and SCR must have only one database in the storage group. You can't enable SCR for a storage group that has more than one database nor add additional databases after SCR is enabled. One database per storage group is the best practice with Exchange 2007 even if you're not using any database replication technologies.

If you have more than one database in a storage group and you want to enable LCR, CCR, or SCR, you'll need to move database content into other storage groups until you have one database per storage group.
