  • Hi Micro,

    Thank you for your question.

    The database on Exchange 2007 is based on the storage group, so we must recover the store group if we want to mount the database, we could refer to the following link to recover the store group, then mount database.

    If there are any questions regarding this issue, please be free to let me know.

    Best Regard,
