Hosted Exchange, which includes Outlook, operates as an efficient software solution that simplifies the general picture — meetings with the owners, apartment viewings or apartment inspections can easily be organized digitally and without paperwork.
There's plenty more application examples to add to the above list. If you are looking for an alternative emailing solution, you're guaranteed to find a suitable product from 1&1 IONOS.
