If a user is managed by a user services policy where UcsAllowed has been set to True ($True) then the user's contacts will be stored in the unified contact store. User server policies have only a single property (UcsAllowed) this property is used to determine the location where a user's contacts are stored. By default, user contacts are kept in Skype for Business Server and not in the unified contact store.Īccess to the unified contact store is managed by using Skype for Business Server user services policies. However, additional user account configuration is required in order to move a user's contacts into the unified contact store.
