From Microsoft 365 to mosa.cloud: how to go about it

More and more organisations want to know where their mail, files and documents are, and who can access them. The mosa.cloud platform brings mail, calendar, files, documents and video calls together in a European workspace built on open source. Switching from Microsoft 365 sounds like a big project. With a good plan it is manageable.

Why switch?

  • Your data stays in Europe. Under European law, on an open source basis.
  • No lock-in. Open standards mean your data can always come with you.
  • One login for everything. Through Zitadel you log in to all your applications with one account.
  • AI built in. mosa.cloud is AI native, within the same European agreements as the rest of your data.

The step-by-step plan

1. Take stock

We map what you have now: mailboxes, shared folders, teams and channels, and links with other systems.

2. Set up

We set up mosa.cloud for your organisation, with your own domain and one login through Zitadel.

3. Test with a pilot group

A small group of colleagues switches first. We solve what they run into before the rest follow.

4. Migrate

Mail, calendars, contacts and files come along. We plan the switch of your mail for a quiet moment, so nobody misses messages.

5. Switch and support

Everyone gets an introduction, and for the first weeks we are on hand for questions.

6. Clean up

Only when everything works well do you cancel the old licences.

How long does it take?

That depends on the size of your organisation and the number of links. For a small organisation it is often a matter of weeks.

Need help with the switch?

We plan the switch with you, set up mosa.cloud and guide your team. Take a look at our Online workspace in mosa.cloud service or get in touch.
