Email and folders
Supported messages and folder structures are migrated from the agreed source mailboxes.
Business email migration
Move business mailboxes from Gmail, IMAP, hosted email or another supported platform into Exchange Online, with the domain cutover and user access planned around the data move.
Email migration scope
An email migration is only complete when messages can be sent and received reliably and users can access the new mailbox.
Supported messages and folder structures are migrated from the agreed source mailboxes.
Contacts and calendar data can be included where the source system and migration method support them.
Mail-routing records are changed at the planned cutover so new messages reach Microsoft 365.
Sender-authentication records are configured appropriately for the services that legitimately send as your domain.
Reconfiguration requirements for Outlook, phones and other clients are identified and assigned.
Inbound and outbound mail flow, access and a representative sample of migrated data are checked.
Common scenarios
A business may have outgrown personal Gmail or Hotmail accounts, inherited several hosted mailboxes, or need better control over leavers, aliases and shared addresses. Moving to Exchange Online can create a consistent platform, but the source limitations still matter.
We identify who owns the domain, where DNS is managed, which systems send email and how users work today. That information shapes the cutover and helps prevent overlooked scanners, websites or line-of-business systems from losing mail access.
Our process
Exact tasks vary by service, but the project remains structured and visible.
Understand the current environment, users, data and constraints.
Agree the target setup, responsibilities, sequence and scope.
Create and configure the destination before moving production data.
Move supported mailbox data and perform the agreed mail-routing and domain cutover.
Test sending, receiving, user access, Outlook configuration and representative migrated items.
Provide clear documentation and explain the completed setup.
Scope and delivery
A defined business email migration commonly includes:
Security and disruption
IMAP migrations normally move email but not calendars, contacts or every mailbox feature. Other source systems may support more complete data transfer. We explain this before choosing the method.
DNS propagation, cached credentials and client reconfiguration can affect the user experience around cutover. The plan identifies the expected transition and who will complete each user-side task.
Why Next Layer IT
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.
Frequently asked questions
Clear answers to common questions about scope, timing and delivery.
Tell us about your projectMany providers can be migrated, but available protocols, authentication and export options vary. We confirm the source capabilities before agreeing what data is included.
Addresses using a domain you control can usually be recreated in Microsoft 365. Addresses owned by a consumer provider, such as an @gmail.com address, cannot become your Microsoft 365 domain address.
The migration and DNS sequence is designed so mail continues to route to an active system. The exact approach depends on the source and may include a final synchronisation after the MX change.
The relevant records are reviewed and configured for the agreed sending services. DMARC should reflect genuine senders and is not applied blindly with a restrictive policy.
Yes, where included in scope. We establish the number and type of devices so reconfiguration responsibilities are clear before cutover.
