    Meera,

    It is a nice Post, but i would like to add my two cents to it. I think it would have been nice if you had also added couple more steps with Screen shots stating that by default once we create RSG it Creates the Database .edb & .stm and log files on default drive. Which can be changed by using ADSIEDIT > Configuration Container > Services > etc. This would help the Exchange Admin who are not that Experienced and are looking for some help from More Experienced Exchange Engineers / Gurus.

    Also be warned about Outlook in recovery mode.
