Попробовал вручную на сервере обновить OAB - ошибка

Action 'Update' could not be performed on object 'Default Offline Address Book'.

Default Offline Address Book
Failed
Error:
Failed to generate the content of the offline address book '\Default Offline Address Book'. Two possible reasons for the failure are that the System Attendant Service is not running or you do not have permission to perform this operation. Error message : 'Error 0x6d9 (There are no more endpoints available from the endpoint mapper) from RpcEpResolveBinding'.

Error 0x6d9 (There are no more endpoints available from the endpoint mapper) from RpcEpResolveBinding

Проверьте из OWA. Если оттуда работает по вышеописанной схеме, значит вполне вероятно что да. »

Из OWA все работает
