Task Migrate Offline Address Book to Exchange 2013 fails with the following output:

Provisioning request failed. Call of method "SW Managed Exchange::UpgradeOAB" failed.

The OfflineAddressBook was not found for organization LDAP://OU=S001001782,OU=Provider,OU=Hosting,DC=hosting,DC=local.
Type: System.ApplicationException.


OWKO (Other-Well-Known-Objects) attribute for Offline Address book on Active directory server is missing.


  1. Append required attribute for organization using XML request on WPE as it is described in the following KB articles: How to edit OWKO of AD object: add/remove data by MPS or WPE call and How to get OWKO of Active Directory object

  2. Restart failed task.
