If I try to launch get-publifolder I get this error
[PS] C:\Program Files\Microsoft\Exchange Server\scripts>Get-PublicFolder
Get-PublicFolder : There is no existing PublicFolder that matches the following
 Identity: '\'. Please make sure that you specified the correct PublicFolder Id
entity and that you have the necessary permissions to view PublicFolder.
At line:1 char:17
+ Get-PublicFolder <<<<
    + CategoryInfo          : NotSpecified: (0:Int32) [Get-PublicFolder], Mapi
   OperationException
    + FullyQualifiedErrorId : A7F40D58,Microsoft.Exchange.Management.MapiTasks
   .GetPublicFolder
The Exchange 2007 server has cas,hub,mbx roles.
I need to delete the public folder database before uninstalling the Exchange 2007. There are no need to use the public folder database and the Exchange 2013 will become the single Exchange Server of the organization.
I thank you so much for your help and remain.
Regards,
Enrico

The homeMDB attribution for System Attendant Mailbox in Exchange 2007 has been added before opening the thread. It was empty, but now it is the DN of a mailbox database as described (http://technet.microsoft.com/en-us/library/dd535374(v=exchg.80).aspx)
As I am transitioning to a single Exchange server 2013 Migration I immagine I can dismiss the public folder database without migrating the system public folder to Exchange 2013. AM I right?
Of course in this situation the migration scripts will fail, so I cannot
I can delete the public folder database using adsiedit.msc, but this will be the last option as I do not want to cause any side effect. Do you agree?
I run the command
