Requirements and exclusions

What is needed and what is not included

→ Prerequisites

  • Your domain is with Netsource Data Systems, or you start a domain transfer (NDS-DOM-DE).
  • Recommended from 300 employees. For smaller organisations NDS-M365-BP is more economical.
  • A one-hour workshop to plan the switch-over of your mail flow

✗ Not included

  • Moving from Exchange on premises or another cloud provider is a separate project (NDS-PRJ-MIG).
  • E3 includes Defender for Endpoint Plan 1. Plan 2 is not part of E3; it needs a separate licence or an upgrade to E5.
  • Telephony is not included. For that we offer VoIP telephony (NDS-WP-VOIP) with 3CX or NFon.
  • Power Platform licences for your own use are booked separately.
