The term 'New-Mailbox' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
Note When this issue occurs, you can still mail-enable an existing user account that was created in Active Directory.
Note By default, Exchange 2010 uses the Exchange shared permissions model, which enables Exchange administrators to create user objects in Active Directory. In some organizations, this behavior is unacceptable. Therefore Exchange 2010 introduced the split permissions model. Split permissions can be configured by using RBAC (recommended) or through Active Directory (configured during the Exchange setup process).
For more information about how to change from RBAC split permissions or Active Directory split permissions to shared permissions, go to the following Microsoft website:
Note You cannot use EMC to change the RBAC split permissions or the Active Directory split permissions to shared permissions.
