Microsoft 365
for SMBs
Migrate to Microsoft 365 with zero downtime. ECLAUD IT, a Microsoft CSP partner, guides you from licence selection to team training.
Microsoft 365 delivers a 162% ROI over 3 years and a 30% productivity gain (Forrester Research). ECLAUD IT migrates your SMB in 2 to 4 weeks, with no interruption, optimised licences, Intune/Defender security activated from day one, and local support in Réunion Island.
Why migrate your SMB to Microsoft 365?
Your on-premises Exchange server is ageing. Windows Server updates keep piling up. Files sit on a NAS that nobody backs up properly. Remote work runs "more or less" over an unstable VPN. We encounter this scenario in 8 out of 10 SMBs we audit in Réunion Island.
Microsoft 365 solves all of these problems in a single migration: reliable Exchange Online email with 99.9% uptime, OneDrive/SharePoint storage accessible from anywhere, integrated Teams collaboration, and Defender/Intune security to protect your devices — no local server required.
Over 2 million businesses worldwide use Microsoft 365. 88% of IT decision-makers have fully deployed it. It is no longer a question of "if" but "when" — and above all, "with whom" for the migration.

Our migration methodology — zero downtime
Audit & inventory
Mapping your current environment: email, files, business applications. Identifying dependencies and constraints.
Licence selection
Recommending the right Microsoft 365 plan for your needs and budget. Optimising licence count by user profile.
10% pilot
Migration of a test group (5–10 pilot users) to validate the process and train early adopters before the full rollout.
Mailbox migration
Migration of Exchange mailboxes, calendars, and contacts. Transparent DNS MX cutover with zero service interruption.
File migration
Transfer of server files to SharePoint (teams) and OneDrive (personal). Folder structure reorganisation if needed.
Security & Intune
Enabling MFA, Conditional Access, Microsoft Defender. Enrolling devices in Intune for centralised management.
Training
Group training sessions: Teams, SharePoint, OneDrive, Outlook. Custom documentation tailored to your teams.
30-day support
Enhanced post-migration support: priority helpdesk, adjustments, resolution of edge cases.
For an SMB with 20 to 50 users, a complete migration (audit, deployment, training, 30-day support) ranges from €5,000 to €15,000 depending on complexity. ROI is typically achieved within 8 to 18 months through savings on local infrastructure and productivity gains.
Microsoft Intune — manage your devices without a local server
Intune replaces your on-premises Active Directory server for device management. From the cloud, you can deploy applications, enforce security policies (BitLocker encryption, password complexity, forced updates), and remotely wipe a lost or stolen device.
It is the ideal solution for SMBs with remote workers or remote sites. No more VPN needed to join the domain — devices are natively managed via the cloud, whether at the office, travelling, or at home.
Multi-OS
Windows, macOS, iOS, Android. Manage all your devices from a single console.
Zero Trust
Conditional Access: only compliant devices can access company data.
Automated deployment
Windows Autopilot: a new PC is fully operational in 30 minutes, apps and policies included.
Secure BYOD
Separate professional and personal data on employees' own devices.
ECLAUD IT, Microsoft CSP partner in Réunion Island
As a Cloud Solution Provider (CSP) partner, ECLAUD IT purchases and manages your Microsoft 365 licences directly through Microsoft. You benefit from a single point of contact for licences, deployment, security, and support — with monthly invoicing in euros.
We do not simply sell licences. Every migration is an infrastructure project: we audit your environment, plan the cutover, migrate your data, activate security (MFA, Intune, Defender), and train your teams. Post-migration support is included for 30 days.
Our difference: we are an outsourced IT department. Microsoft 365 is part of our broader managed services offering. After the migration, we continue to manage your M365 tenant, your devices via Intune, and your security via Defender — everything is managed and monitored.
FAQ — Microsoft 365 for SMBs
Which Microsoft 365 licence should I choose for my SMB?
For an SMB with 10 to 120 seats, we recommend Business Premium (approximately €20/user/month). It includes Office apps, Teams, Exchange, SharePoint, OneDrive, as well as Microsoft Intune for device management and Defender for Business for security. It offers the best features-to-price ratio for SMBs.
How long does a Microsoft 365 migration take?
For an SMB with 20 to 50 users, allow 2 to 4 weeks. The pilot phase takes 1 week, mailbox migration 2–3 days, file migration 1 week, and training 2–3 days. The goal is zero downtime through a progressive, batch-by-batch migration.
Is my data safe in the Microsoft cloud?
Microsoft 365 is hosted in datacentres certified ISO 27001, SOC 2 and GDPR-compliant (datacentres in France and Europe). Encryption is active at rest and in transit. With Business Premium, you also benefit from Microsoft Defender, MFA, and Conditional Access.
What is Microsoft Intune and why use it?
Intune is Microsoft's centralised device management solution (MDM/MAM). It lets you deploy applications, enforce security policies, encrypt drives, and remotely wipe a lost device — all from the cloud, with no local server required. Included in Business Premium.
What is the difference between SharePoint and OneDrive?
OneDrive is your personal space (individual documents, drafts). SharePoint is the team space (shared documents, collaborative projects). In practice, every Teams channel automatically creates a SharePoint site. The rule: if the document belongs to the team, it goes on SharePoint.
What is a Microsoft CSP partner?
A CSP (Cloud Solution Provider) is a Microsoft-authorised reseller who can purchase, manage, and bill Microsoft 365 licences on behalf of clients. The benefit: a single point of contact for licences, deployment, support, and monthly invoicing. ECLAUD IT is a CSP partner.
