Microsoft 365 was once the undisputed standard for business productivity. But in 2026, more and more European companies are considering moving on. Here's why — and how.
5 Concrete Reasons to Leave Microsoft 365
1. Prices Increasing Every Year
Microsoft has raised its Microsoft 365 prices significantly in recent years: +20% in Europe in 2023, then +12% in 2024. The Microsoft 365 Business Standard plan is now €12.50/user/month (annual), versus €9.99 for kSuite Professional.
Cost impact: For a 20-person company, that's €600/year more than kSuite just on licensing — not counting migration time.
2. The CLOUD Act: A Real Risk for European Businesses
Microsoft is a US company. Under the CLOUD Act (2018), US authorities can force any American company to hand over data stored on its servers — regardless of the data's location. Even if your OneDrive data is in Dublin, Microsoft can be forced to disclose it.
This risk is particularly significant for law firms, accounting practices, healthcare organisations, and companies handling personal data.
3. Teams: Heavy, Complex, Omnivorous
Microsoft Teams consumes enormous system resources, requires Windows or Chromium, and mixes incompatible use cases (videoconferencing + messaging + channels + meetings...). Its complexity generates significant hidden costs: internal training, IT support, configuration time.
4. OneDrive: Synchronisation Issues
OneDrive remains notoriously problematic: sync conflicts, unexplained errors, high battery consumption, recurring issues on macOS. kDrive, by comparison, offers a native experience recognised for its stability.
5. Data Lock-in
Microsoft formats (DOCX, XLSX, PPTX) are dominant but not open. Exporting your entire history, your SharePoint structure, your Teams conversations — this is possible but complex, costly, and often incomplete.
What to Replace Microsoft 365 With?
Infomaniak's kSuite covers all Microsoft 365 use cases:
| Microsoft 365 | kSuite Equivalent |
|---|---|
| Outlook | kMail (IMAP/Exchange-compatible) |
| OneDrive | kDrive (3 TB/user) |
| Teams | kChat + kMeet |
| Office (Word, Excel, PPT) | OnlyOffice (integrated in kDrive) |
| SharePoint | kDrive shared spaces |
| Exchange | Infomaniak Business Mail |
How to Migrate Concretely?
- Audit your current usage: which Office features are actually used? (Most use only 20% of them.)
- Export your data: emails via IMAP, files via OneDrive sync, calendar via ICS, contacts via vCard.
- Migrate email first: via IMAP migration tool (integrated into Infomaniak Manager).
- Transfer files: sync your local OneDrive folder, then upload to kDrive via desktop client.
- Switch Teams: deploy kChat (Mattermost-based) with your existing team structure.
- Cancel Microsoft: wait for your renewal date and cancel at least 30 days beforehand.
Recommended timeline: Allow 2-4 weeks for a company of 10-20 people, including staff training time.
Real Cost Savings
For a company of 15 users:
- Microsoft 365 Business Standard: 15 × €12.50 = €187.50/month
- kSuite Professional: 15 × €9.99 = €149.85/month
- Savings: €37.65/month = €451.80/year
Add: no more Teams licensing, 3 TB kDrive per user (vs 1 TB OneDrive), Swiss-hosted email.
