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).
+ CategoryInfo : NotSpecified: (0:Int32) [Set-Group], InvalidObjectOperationException
+ FullyQualifiedErrorId : ErrorID,Microsoft.Exchange.Management.RecipientTasks.SetGroup


This issue occurs because the Exchange Server 2010 server uses the Update-Recipient cmdlet to add Exchange Server 2010 attributes to the distribution group. However, the Update-Recipient cmdlet does not set the msExchVersion property of the distribution group.


To resolve this issue, install the following update rollup:

2685289 Description of Update Rollup 3 for Exchange Server 2010 Service Pack 2


To work around this issue, manually update the msExchVersion property by using the Active Directory Service Interfaces (ADSI) Edit tool (Adsiedit.msc), or run the Get-DistributionGroup | Set-DistributionGroup cmdlet in Exchange Management Shell.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
