How to Choose the Right Microsoft 365 Partner for Your SME

Microsoft 365 is easy to buy - Choosing the right partner is harder.

The licences may be identical, but the service behind them can vary enormously. One provider may simply provision subscriptions and answer billing questions. Another may manage your users, devices, security, backups and support desk.

That difference becomes painfully clear when email stops working, someone loses a laptop or an employee leaves with access to sensitive files.

You are not just choosing where to buy Microsoft 365. You are choosing who may help run a critical part of your business.

Here is what to look for.

Licence reseller or managed service provider?

A licence reseller sells Microsoft 365 subscriptions.

A managed service provider, or MSP, helps you operate the environment after those licences are activated.

A reseller may be enough if you already have an experienced internal IT team. It can recommend licence types, provision subscriptions and manage renewals.

Most SMEs need more than that.

A good MSP can support users, manage permissions, configure security, enrol devices, handle onboarding and offboarding, monitor problems and help you plan future changes.

Think of the reseller as the shop.

The MSP is the team that helps you configure, protect and maintain what you bought.

Ask every provider:

What do you manage after the licences are activated?

The answer should be specific. If it centres only on billing and renewals, you are probably speaking to a reseller rather than an operational IT partner.

Also ask whether the provider will manage your existing environment or simply recommend additional Microsoft products. A strong partner should be able to explain what it would improve before trying to sell you more licences.

Migration and onboarding

A Microsoft 365 migration is not just about moving email.

Depending on your current setup, the partner may need to migrate:

• Mailboxes and calendars

• Shared email accounts

• Files and folders

• OneDrive data

• SharePoint sites

• Teams content

• User permissions

• Devices and applications

The technical work matters. So does the disruption to your employees.

A reliable partner should provide a written migration plan covering preparation, testing, communication, cutover and post-migration support.

Ask exactly what users will experience.

Will email be unavailable? For how long? What happens to mobile devices? Will people need new passwords? Who will help employees who cannot log in on the first morning?

“Minimal downtime” is not a useful answer.

You need a timetable, named responsibilities and a fallback plan.

For larger or more complex migrations, ask the partner to run a pilot with a small group before moving everyone else. A pilot will not eliminate every issue, but it can expose problems with permissions, devices, applications or user communication before they affect the whole business.

The proposal should also explain what happens after the migration. Data movement may finish overnight, but user support often continues for days.

Ongoing support

The migration is only day one.

After that, people join and leave. Devices need replacing. Permissions change. Microsoft releases new features. Users encounter problems with Outlook, Teams, SharePoint and OneDrive.

Your support agreement should clearly explain what happens next.

Check whether it covers:

• Creating and removing users

• Changing licences

• Password and access problems

• Email and mailbox issues

• Teams, SharePoint and OneDrive support

• Device enrolment

• Security alerts

• Account compromises

• Permission changes

• Regular service reviews

Find out who actually provides the support.

Will your employees speak to a team that knows your environment, or will every request enter a generic queue?

Can users contact the provider directly, or must everything go through one person in your business?

Neither model is automatically wrong. What matters is knowing how it works before you sign.

Ask how the provider documents your environment, too. If the person who completed your migration leaves, another engineer should still be able to understand your configuration, policies and known issues.

Intune and device management

Hybrid work has changed where business data lives.

Employees access Microsoft 365 from offices, homes, hotels and client sites. They use company laptops, personal phones and sometimes unmanaged devices.

That creates risk.

Microsoft Intune helps organisations manage devices, applications and access to company information. It can enforce security policies, deploy software, check whether devices meet company requirements and remove business data from lost or retired devices.

Microsoft provides an official overview of what Intune does.

For an SME, device management can help with:

• Laptop encryption

• Screen-lock policies

• Security updates

• Application deployment

• Device compliance checks

• Remote removal of company data

• Standardised laptop setup

• Control over personal devices accessing business information

Ask the provider whether Intune is included in your proposed licence plan and what configuration work is included in the service.

Buying the licence is not the same as configuring it properly.

You should also understand whether the provider will manage only company-owned equipment or support personal devices under a bring-your-own-device policy.

Microsoft 365 security

Passwords alone are not enough.

At a minimum, your partner should implement multifactor authentication for all users and stronger controls for administrator accounts.

It should also be able to advise on:

• Conditional Access

• Legacy authentication

• Suspicious login monitoring

• Email threat protection

• Anti-phishing controls

• Device compliance

• Privileged access

• Onboarding and offboarding

• Periodic access reviews

Microsoft Entra Conditional Access can use signals such as identity, location, device status and sign-in risk to decide whether access should be allowed or challenged.

You can read Microsoft’s overview of Conditional Access.

Be cautious if a provider says, “Microsoft handles the security.”

Microsoft protects the underlying cloud service. Your business still controls users, permissions, devices, configurations and access policies.

Those responsibilities need active management.

Ask the provider what it would do during the first 30 days to improve your security. A good answer should be prioritised and specific. It may include reviewing administrator accounts, enforcing multifactor authentication, disabling legacy authentication, checking mailbox forwarding rules and tightening access for departing employees.

Backup and recovery

Many SMEs assume Microsoft 365 automatically backs up everything they might need.

That is not a safe assumption.

Microsoft provides resilience, retention tools and recovery features. But that does not automatically give every business the backup coverage, retention period or recovery process it requires.

Microsoft uses a shared responsibility model. Microsoft protects the cloud infrastructure, while customers remain responsible for areas including their data, identities, devices and configurations.

Your backup discussion should cover:

• Exchange Online mailboxes

• OneDrive

• SharePoint

• Teams-related data

• Backup frequency

• Retention period

• Data location

• Recovery times

• Deleted-user data

• Accidental deletion

• Malicious deletion

• Recovery testing

Ask the provider to explain exactly how a deleted mailbox, folder or SharePoint site would be restored.

Better still, ask for a demonstration.

The answer should explain where the backup is stored, how far back recovery can go and how long restoration is expected to take.

Do not accept “Microsoft keeps everything” as a backup strategy. Retention and backup are related, but they are not always the same thing.

You do not want the first real recovery test to happen during an emergency.

Response times and SLAs

“We respond quickly” is not a service level agreement.

A proper SLA should explain how incidents are prioritised and what response you can expect.

For example:

• Critical: The business cannot operate, several users are affected or there is an active security incident.

• High: An important system is badly affected, but some work can continue.

• Medium: One user or a non-critical service is affected.

• Low: A routine request or planned change.

Make sure the agreement distinguishes between:

• Initial response

• Start of investigation

• Update frequency

• Service restoration

• Final resolution

These are different things.

A provider may meet a 30-minute response target by sending an automated acknowledgement. That does not mean anyone has started solving the issue.

Also ask what happens outside normal business hours. Is emergency support included? Who handles escalation? Are there additional charges?

Check whether the SLA applies only to incidents raised through a particular portal. An urgent email sent to the wrong address may not start the contractual response clock.

Realistic SLAs are better than impressive promises hidden behind exclusions.

Pricing model

Microsoft 365 support may be priced:

• Per user

• Per device

• At a flat monthly rate

• By support hours

• Through a combination of these models

There is no universally correct structure.

Per-user pricing is easy to understand and scales with headcount. A flat monthly fee can simplify budgeting. Hourly support may appear cheaper, but it can discourage employees from reporting smaller problems before they become larger ones.

Do not compare only the headline number.

Check whether the fee includes:

• Licence administration

• User support

• Onboarding and offboarding

• Intune management

• Security monitoring

• Backup

• Onsite visits

• Out-of-hours support

• Service reviews

• Reporting

• Migration or project work

Ask what is specifically excluded.

Many supplier disputes begin because the buyer believed something was part of the managed service while the provider treated it as an additional project.

The proposal should make that boundary obvious.

Also check the commercial terms around licence increases, annual price changes and contract renewal. A competitive monthly fee matters less if the agreement makes it difficult or expensive to switch provider later.

Local or remote support?

Most Microsoft 365 issues can be handled remotely.

That is usually faster and gives you access to a wider pool of specialists.

Onsite support still matters in some situations:

• Several devices fail at once

• A new office is opening

• Network equipment is involved

• Hardware must be replaced

• Employees need hands-on assistance

• A problem cannot be diagnosed remotely

A remote-first provider may work perfectly for a distributed company.

A business with shops, warehouses, clinics or operational sites may need someone who can physically attend.

Ask whether onsite work is handled by the provider’s own employees or subcontractors. Confirm the geographical coverage, likely response time and cost.

“Onsite support available” can mean anything from same-day attendance to someone travelling across the country next week.

Local presence should not be treated as proof of quality. A nearby provider with weak processes may deliver worse support than a remote specialist with clear ownership, strong documentation and reliable escalation.

Questions to ask before signing

Use these questions to get beyond the sales pitch:

• What will you manage after our Microsoft 365 licences are activated, and what will remain our responsibility?

• How will you protect and recover our Exchange, OneDrive, SharePoint and Teams data?

• Which security controls would you implement during the first 30 days?

• What is included in the monthly fee, and what would be charged separately?

• Who supports our users, during which hours, and what happens during a serious incident?

• How do you document our environment and manage changes?

• What happens if we decide to move to another provider?

• Can you provide examples of similar businesses you already support?

One more question often reveals a lot:

If you took over our Microsoft 365 environment tomorrow, what would you review first?

A strong partner will give you a clear, prioritised answer.

A weak one will start by selling you more licences.

Choose for the business you are becoming

The right Microsoft 365 partner should reduce risk, minimise disruption and make your technology easier to manage.

Price matters. So do response times, security, backup, user support and the provider’s ability to understand your business.

Look for a partner that fits your size and working model. Make responsibilities explicit. Challenge vague promises. Ask how recovery works before you need it.

Do not choose only for the business you operate today.

Consider what happens when you hire more people, open another location, introduce new applications or face stricter customer security requirements. A suitable partner should be able to support that growth without forcing you into an enterprise service model you do not need.

Changing provider later is possible.

Choosing carefully now is cheaper.
