Exchange Online mailboxes
Business email, folder structures and supported mailbox data can be migrated using a method suited to the source platform.
Microsoft 365 migration services
Microsoft 365 Migration Services for UK Businesses
Move business email, users and relevant cloud data into Microsoft 365 with the tenant, domain, licences and security settings prepared around the migration rather than treated as afterthoughts.
What we migrate and configure
The connected parts of a Microsoft 365 move.
A Microsoft 365 migration is more than copying mailbox data. Users, identities, licences, DNS and access need to work together at cutover.
Calendars and contacts
Where the source and migration method support them, calendars and contacts are included and checked after migration.
Users and licences
User accounts and licence assignments are prepared against the agreed target design before cutover.
Domain and DNS
Domain verification, MX, SPF, DKIM and appropriate DMARC work is planned around mail-flow changes.
MFA and access
Multi-factor authentication and sensible administrator access controls are incorporated into the setup.
OneDrive and SharePoint
Relevant file migrations can be scoped alongside email where source data, permissions and volumes are suitable.
Common scenarios
When a Microsoft 365 migration makes sense.
Businesses commonly reach a point where personal email, fragmented hosting or an older tenant makes day-to-day administration harder than it should be. A planned migration creates one controlled destination rather than adding another workaround.
The right method depends on the source. A Gmail move, an IMAP migration and a tenant-to-tenant project have different capabilities and limitations, so the source is assessed before dates or outcomes are promised.
Projects often start with
- Moving business email from Google Workspace or Gmail
- Replacing IMAP, ISP or legacy hosted mailboxes
- Creating a new Microsoft 365 environment for a growing team
- Separating or consolidating tenants where technically appropriate
- Combining email migration with scoped OneDrive or SharePoint work
Our process
A defined route from assessment to handover.
Exact tasks vary by service, but the project remains structured and visible.
- 01
Assess
Understand the current environment, users, data and constraints.
- 02
Plan
Agree the target setup, responsibilities, sequence and scope.
- 03
Prepare
Create and configure the destination before moving production data.
- 04
Deliver
Migrate agreed mailbox and cloud data, then complete the planned domain and mail-flow changes.
- 05
Verify
Check user access, mail flow, migrated data, DNS and the agreed security configuration.
- 06
Handover
Provide clear documentation and explain the completed setup.
Scope and delivery
What is included.
The exact Statement of Work is project-specific. A typical Microsoft 365 migration can cover:
- Current-environment assessment
- Target tenant and user preparation
- Agreed mailbox data migration
- Domain verification and DNS cutover
- Licence assignment and MFA setup
- Mail-flow and access testing
- Migration record and handover notes
Security and disruption
Practical risks are discussed before changes begin.
Source access, mailbox size, archive data, throttling and unsupported item types can affect the method and duration. These constraints are identified during assessment rather than discovered at the end.
DNS updates can create a transition period while records propagate. Changes are sequenced to minimise disruption, but zero downtime is not promised. Users also need a clear plan for Outlook, mobile devices and new sign-in details.
Why Next Layer IT
Technical project work without an unnecessary support contract.
Our engineers carry out the agreed technical work, explain decisions in plain English and document the handover. We keep the focus on the project rather than using it as a route into services you did not ask for.
- Scope agreed before production changes
- Straightforward pricing and responsibilities
- Security considered as part of delivery
- Verification and documented handover
Frequently asked questions
Microsoft 365 migration questions
Clear answers to common questions about scope, timing and delivery.
Tell us about your projectIs Office 365 migration the same as Microsoft 365 migration?
The terms are often used interchangeably. Office 365 was the earlier product name for many cloud services now sold within Microsoft 365. The scope still needs to specify whether the project includes email only, identities, files, devices or other services.
Can you migrate all existing email?
Often, but the source platform, connection method, mailbox condition and item types determine what can be moved. We assess the source and explain any known exclusions before agreeing the scope.
Can we keep our existing business domain?
Usually yes, provided the business controls the domain and DNS. The domain is verified in Microsoft 365 and mail records are changed at the planned point in the migration.
Will staff need new Outlook profiles?
They may. The requirement depends on the existing configuration, devices and migration method. User reconfiguration tasks are included or clearly assigned in the plan.
Do you supply Microsoft 365 licences?
Licence requirements are identified during planning. Any licence supply or customer purchasing responsibility is stated clearly in the quote rather than assumed.
