Why Microsoft 365 for mid-market firms?

Microsoft 365 is the most common cloud workplace in German mid-market companies: Exchange Online replaces on-prem mail, Teams replaces separate conferencing tools, SharePoint and OneDrive replace file servers—one system, reachable from anywhere. Firms still running local Exchange and file servers often spend more on maintenance and licences than with M365; a well-run migration typically pays back in 12–24 months.

Poor planning causes data loss, downtime and user rejection. We structure rollouts: analysis, migration, training and hypercare—so staff become productive quickly and IT is relieved. See also cloud migration and IT consulting; ERP/API connectivity via API integration.

Frequently asked questions

  • What does a Microsoft 365 rollout cost for a mid-market company?
    Licences run roughly €6–22 per user/month (Business Basic to Premium). One-off migration consulting typically €5,000–25,000 depending on user count, legacy mail/file servers and hybrid complexity. Organisations with 100+ users or hybrid Active Directory often budget €15,000–40,000 for guided migration, onboarding and admin training. Funding programmes may subsidise consulting—ask us for a transparent fixed-price scope.
  • How does a Microsoft 365 migration work?
    In five phases: inventory (systems, mailboxes, files), planning (cutover vs staged vs hybrid), pilot with a small group, main migration by department or site, then hypercare for two weeks so users become productive quickly. We cover all phases and train your admins and key users.
  • What is the difference between Microsoft 365 and Office 365?
    Office 365 was renamed Microsoft 365 in 2020. M365 is the umbrella for Office apps, Exchange Online, Teams, SharePoint, OneDrive and—on Premium plans—security and endpoint management (Defender, Intune). Business Standard is the most common plan for desktop Office plus cloud collaboration.
  • Can Microsoft 365 connect to on-premise IT?
    Yes. Azure AD Connect syncs on-prem Active Directory for single sign-on. Exchange hybrid supports phased mailbox moves. SharePoint and file servers can bridge via Azure File Sync or gateways. We design hybrid architectures so you migrate at your own pace without downtime spikes.
  • How do we secure Microsoft 365 against phishing and data loss?
    Baseline: MFA for all users, Conditional Access, Defender for Office 365, DLP policies and regular permission reviews. Business Premium includes the security features most SMEs need. We harden tenants before broad rollout.
