The EBF Contacts app makes your colleagues more accessible on mobile devices. It reads contacts from Exchange Online or On-Premise, stores contact data locally in encrypted form, and synchronizes regularly. This makes it possible to retrieve relevant information from colleagues at any time and identify internal callers. This is because the names of callers from your own company are displayed even if they are not manually stored in your own address book. Manual maintenance of contact data becomes superfluous and private and business contacts remain clearly separated.
