Do we have to leave Microsoft 365 entirely?
No. Many clients run a hybrid setup: IceWarp for mail and collaboration, M365 only where individual applications genuinely require it. That reduces cost and dependency at the same time.
Can we start step by step?
Yes. The four building blocks can be introduced individually or together, and a hybrid setup is explicitly an option. In the sovereignty consultation we identify the areas where dependency is a genuine risk for you and leave the rest running.
Can our employees keep using Outlook?
Yes. IceWarp is Outlook-compatible and also includes a fully-fledged web client. The adjustment is minimal.
How much effort is the migration?
We migrate mailboxes, calendars and data with proven tools, typically over a weekend, without interrupting work. Migration is part of our service package.
Where is our data held for IaaS and backup?
The infrastructure runs in the German data centres of our partner IONOS, with clear data residency and a European contracting party. The backup with NovaStor, a German vendor, is kept separate from your production systems: your last line of defence does not sit with the same provider as your production data.
Is “German” automatically more secure?
No. What is secure is what is well operated. The difference lies in legal access, pricing power and reachability. That is why we combine sovereign platforms with managed operations.
What about our existing licence agreements?
We plan around your contract terms: the switch is timed so that you never pay twice. We work through the numbers in the initial consultation.
