Deep Outlook dependency & user resistance
Your teams rely on Outlook desktop workflows daily. Changing those habits feels risky, even impossible. We handle the change management and keep Outlook operational throughout the transition, so users adapt gradually — not overnight.
Complex Exchange calendaring tools
Exchange's Calendar, Resource Mailboxes, and shared calendars are intricate. Migrating these to Nextcloud without data loss or permission errors is non-trivial. Our senior engineers have done it before, repeatedly.
Strict public-sector compliance & sovereignty
EU municipalities and defense contractors must eliminate US-backed vendors under digital sovereignty mandates. Moving from Exchange to Nextcloud is the path, but you cannot afford a security gap or compliance violation during the switch.
Microsoft Exchange Server → Nextcloud Groupware migration — your questions answered
How do you handle Outlook dependency during an Exchange to Nextcloud migration?+
We keep your legacy Exchange environment under VENDOR support as long as your contract is active. Users continue using Outlook with Exchange while we build Nextcloud. We migrate gradually, so there's no sudden workflow disruption. After migration, Nextcloud's Outlook integration maintains calendar and Mail access via the same client.
What about complex Exchange calendaring — shared calendars, resource mailboxes, delegate access?+
These are specific to Exchange's architecture. Our senior engineers map each calendar element — shared calendars, resource mailboxes, delegate permissions — to Nextcloud equivalents before migration. We test in a staged environment so nothing breaks.
How does this support European digital sovereignty requirements?+
Nextcloud is open-source and can be self-hosted on your own infrastructure in the EU. You control all data, metadata, and access. Your legacy Exchange stays supported throughout the migration, so you meet compliance mandates without a gap. After migration, our third-party support covers most operational issues if your Exchange contract lapses.
What if our vendor support renewal deadline arrives before we finish migrating?+
Your legacy Exchange stays under VENDOR support as long as your contract is active, so you can migrate on your timeline with no forced cutover. If the renewal lapses, our independent third-party support covers MOST operational issues on the legacy platform while you complete the move. It is not vendor support and does not include vendor patches — we are transparent about that scope.
Ready to own your communication Hub?
Your Nextcloud Hub — Mail, calendar, chat, and files — is a complete self-sovereign replacement for Exchange. We keep the legacy platform supported during the transition, then hand you a fully operational Nextcloud environment with ongoing Nextcloud Hub Platform Administration and Secure On-Prem Support Services.
