I am in the process of testing a transition from 2003 to 2007.I installed the CA, Hub and Mailbox roles sucessfully. I then went to mount the database in First Storage Group which was created by default but it didn't allow me to do it, it did have an error but im not in the office at the moment so can't really get a copy of it.I deleted the storage group and tried to create a new one. So I follow the wizard, specify a name and paths to store the database and log files but it won't allow me to create the storage group it returns an error along the lines of 'this cannot contain a null or empty object', again i can't get the exact error. Does anyone have any idea what is wrong?

I had to use the EMS. I'm wondering why this doesn't work in the GUI (Beta2). The error was "The arguement cannot be null or empty". It was attemping to run the new-Storagegroup command without any arguments even thoughI specified them in the wizard.

I couldn't mount the database either. After doing a search on here I ran /preparelegacyexchangepermissions. Didn't fix it. It was fixed with /PrepareDomain I ran /PrepareAD before installation, shouldn't the above be run as well? Bug? Thanks
