I'm encountering issues with a OAB that was migrated from Exchange 2003 to 2010. I've moved the OAB using Move-OfflineAddressBook
and set the new Exchange 2010 as generation server. Nevertheless the OAB version is still 0.0. That means that I can not enable web based distribution for that OAB. I tried to upgrade the OAB using Set-OfflineAddressBook "name of oab" -ApplyMandatoryProperties
which resulted in an error saying
MinAdminVersion should not be empty when Exchange Version is 0.10 (14.0.100.0).
Is there any way to upgrade the OAB to support web distribution?
