Assume that you create a distribution group in Microsoft Exchange Server 2003 in a mixed Exchange Server 2003 and Exchange Server 2010 environment. Then, you try to use the distribution group in the hierarchical address book by running the Set-Group -Identity distribution group -IsHierarchicalGroup $true
cmdlet in Exchange Management Shell on an Exchange Server 2010 server. In this situation, the operation fails and you receive the following error message:
Property IsOrganizationalGroup can't be set on this object because it requires the object to have version 0.10 (14.0.10 0.0) or later. The object's current version is 0.0 (6.5.6500.0).
