Microsoft 365
for SMBs

Prepare a Microsoft 365 migration with inventory, tests, change windows and rollback. ECLAUD IT's support scope is defined in the proposal.

In summary

A Microsoft 365 migration should begin with an inventory of identities, data, applications, licences, security controls and operational constraints. Schedule, continuity, configuration and support are confirmed in the proposal.

01 — Why migrate

Why migrate your SMB to Microsoft 365?

A migration may be considered when email, storage, backup or remote-access arrangements no longer meet the organisation's needs. The initial inventory must measure those gaps without assuming the organisation's situation.

Microsoft 365 combines email, storage, collaboration and management tools. Availability, security features, licences and limits must be checked against official documentation and the selected proposal.

Migration
Define batches, tests and rollback
Outcomes
Measure for the organisation

The decision depends on usage, constraints, full costs, security requirements and an exit plan. No universal benefit is promised.

02 — Ecosystem

Microsoft 365, far more than an office suite

Microsoft 365 is a complete ecosystem that replaces your Exchange server, file server, VPN, and antivirus — in a single cloud subscription.

Exchange Online

Professional email, shared calendars and contacts. Storage and Microsoft service commitments are those in the current selected licence terms.

Microsoft Teams

Video conferencing, chat, team channels. Replaces the office phone with Teams Phone.

SharePoint & OneDrive

Cloud storage 1 TB/user. File sharing, versioning, real-time co-editing.

Office Apps

Word, Excel, PowerPoint, Outlook — on the web and desktop. Always up to date, no perpetual licence.

Microsoft Intune

Centralised device management (MDM). App deployment, security policies, BitLocker encryption.

Defender for Business

Cloud antivirus/EDR, email protection, Safe Links, Safe Attachments. Built-in security.

04 — Migration

Migration methodology and continuity targets

1

Audit & inventory

Mapping your current environment: email, files, business applications. Identifying dependencies and constraints.

2

Licence selection

Recommending the right Microsoft 365 plan for your needs and budget. Optimising licence count by user profile.

3

Pilot

The pilot group, acceptance criteria and rollout decision are defined in the migration plan.

4

Mailbox migration

Mailbox, calendar and contact transfer is planned with a change window, acceptance tests and rollback plan.

5

File migration

Transfer of server files to SharePoint (teams) and OneDrive (personal). Folder structure reorganisation if needed.

6

Security & Intune

Enabling MFA, Conditional Access, Microsoft Defender. Enrolling devices in Intune for centralised management.

7

Training

Group training sessions: Teams, SharePoint, OneDrive, Outlook. Custom documentation tailored to your teams.

8

Post-migration support

Support duration, channels, service hours and priorities are stated in the proposal.

Indicative cost

Migration scope and price depend on users, data volume, source systems, security, training, cutover and support requirements. No universal price, saving or return-on-investment period is claimed; these are assessed in the proposal.

05 — Device management

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 can deploy applications and policies when configured; completion time depends on hardware, connectivity and the agreed build.

Secure BYOD

Separate professional and personal data on employees' own devices.

06 — Why us

Licence sourcing, invoicing, deployment, security and support responsibilities are confirmed in the proposal. No Microsoft CSP status or direct-purchase arrangement is claimed without current official evidence.

A migration proposal may include assessment, cutover planning, data migration, security configuration, training and post-migration support. Exact responsibilities, support period and exclusions are confirmed in writing.

Microsoft 365 can form part of an outsourced IT department engagement. Tenant, device and security-tool management is included only when the proposal defines its scope, access, service hours and responsibilities.

07 — Frequently asked questions

FAQ — Microsoft 365 for SMBs

Which Microsoft 365 licence should I choose for my SMB?

Licence selection depends on required applications, device management, security, compliance and current Microsoft terms. The proposal documents the selected plan, licence responsibilities and current price; no plan is universally recommended.

How long does a Microsoft 365 migration take?

Duration depends on the users, mailboxes, files, applications, identity design, change windows and acceptance tests. The schedule, continuity targets and rollback plan must be approved for the project.

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 an organisation authorised by Microsoft to provide certain licensing services. No ECLAUD IT CSP status is published here without current official evidence.
