Move your mailboxes to Exchange Online with a planned cutover, tested mail flow, and no gap where email simply stops arriving.
We map every mailbox, distribution list, permission and shared calendar before touching anything, so nothing gets left behind.
DNS and MX record changes are timed and tested carefully, so incoming email keeps arriving throughout the cutover.
The same team that plans your migration configures, tests and supports Exchange Online afterwards — no handover gaps.
Moving mailboxes to Exchange Online sounds like a technical formality until you're the business relying on it — a poorly planned migration can mean missing emails during the cutover window, calendars that lose shared appointments, distribution lists that silently stop forwarding, or mailbox permissions and delegate access that never get recreated on the new platform. Proper exchange online migration services exist precisely because moving from an on-premise Exchange server, a previous hosted email provider, Google Workspace, or an ageing IMAP setup, involves more moving parts than a simple "copy the emails across" job: DNS and MX record changes, autodiscover configuration, mailbox permissions and delegate access, shared and resource calendars, distribution lists and mail-enabled security groups, and PST archives that need importing without losing folder structure.
The method matters as much as the mechanics. A cutover migration moves everything in one window and suits smaller mailbox counts; a staged migration moves users in batches over days or weeks, useful for larger organisations; and a hybrid migration keeps some mailboxes on-premise while others move to the cloud, often used where a phased transition is preferred. Choosing the wrong method for your mailbox count and business tolerance for downtime is one of the most common reasons a migration ends up feeling far more disruptive than it needed to be.
Getting DNS and MX records right is where migrations most commonly go wrong for smaller businesses without dedicated IT resource. Change the MX record too early, before mailboxes are actually ready in Exchange Online, and incoming mail can be lost or delayed. Leave it too late after mailboxes have moved, and users end up checking the wrong inbox. A properly planned migration sequences DNS changes precisely against mailbox readiness, so there's no window where email has genuinely nowhere reliable to land.
The businesses that get burned by a bad Exchange Online migration usually share the same pattern: a provider who quoted quickly without auditing the existing environment, DNS changes made without a tested rollback plan, and distribution lists or shared mailboxes that were assumed to "just carry over" and never got checked until someone noticed a customer enquiry had gone unanswered for a week. None of this is complicated to avoid — it just requires someone to actually map the environment properly before touching DNS records, rather than treating exchange online migration services as a one-afternoon job that ends the moment the last mailbox shows a green tick.
Every migration begins with a discovery call and a technical audit of your existing environment — how many mailboxes, how much data each holds, which distribution lists and shared mailboxes exist, and what permissions and delegate access are currently configured. We map every dependency against Exchange Online before quoting, so there are no surprise gaps discovered mid-migration.
We plan MX, SPF, DKIM and autodiscover record changes against a tested timeline, so mail flow transitions smoothly rather than dropping into a gap between the old and new systems.
Shared calendars, resource bookings, distribution lists and mailbox delegate permissions are mapped and recreated in Exchange Online, not left as a "figure it out later" problem for your team.
Where mailboxes have local PST archives, we import them into Exchange Online preserving folder structure, so years of email history aren't dumped into a single unsorted folder.
A complete, managed migration to Exchange Online.
A full review of your mailboxes, data volumes, distribution lists and permissions, with a written migration plan before anything is moved.
MX, SPF, DKIM and autodiscover records sequenced and tested so incoming mail never has a gap to fall into.
Emails, calendars, contacts and PST archives migrated with folder structure and permissions intact.
Every group, shared mailbox and resource calendar recreated and tested in Exchange Online before go-live.
Your team is shown how to access their new mailbox, with the same support desk on hand for anything that needs adjusting afterwards.
Every mailbox, calendar and distribution list is tested against a checklist before we call a migration complete, not just a sample of the busiest accounts.
We keep your previous mail platform accessible during the transition period wherever possible, so there's a fallback if anything needs more time to bed in.
From your first call to a fully tested, live Exchange Online environment.
We review your current mailboxes, data volumes, distribution lists and permissions in detail before quoting anything.
We agree a migration method — cutover, staged or hybrid — and a DNS cutover date that fits around your business.
Mailboxes, calendars and distribution lists are migrated and tested, with the old system kept available as a safety net.
Staff guidance and ongoing support after go-live, so any teething issues are resolved quickly.
We treat migration as a project with a plan and a checklist, not a switch you flip and hope for the best. Every migration starts with a proper audit of your existing environment, so we know exactly what needs to move before we quote or schedule anything.
DNS and MX record changes are sequenced and tested carefully — this is where most DIY migrations go wrong, and we manage that process directly rather than leaving it to a generic support ticket.
We keep your previous mail system accessible during the transition wherever possible, so there's always a safety net if something needs more time, rather than a hard cutover with no way back.
Distribution lists, shared mailboxes and delegate permissions are mapped and recreated properly, not left as a mystery for your team to untangle after go-live.
As an IT support provider first, your Exchange Online environment sits under the same support desk as the rest of your IT, so any issue afterwards is one call, not a search through separate supplier contracts.
Our managed plans start from £20 per user per month and include cloud backup for Microsoft 365 data as standard, so your mailboxes are protected against accidental deletion from day one, not left relying solely on Microsoft's default retention.
We're also honest about timelines and dependencies. If your mailbox count or PST volume means a staged approach will genuinely be smoother than a single cutover weekend, we'll say so upfront rather than promising the fastest possible timeline and letting quality slip to hit it.
We treat every migration as a project with a plan, not a leap of faith.
We map your existing environment in full before proposing a plan, so there are no surprises once the migration begins.
MX, SPF, DKIM and autodiscover changes are sequenced and tested, not left to a generic checklist.
We don't switch off your existing mail platform until the new one is proven, so there's always a fallback.
We test every mailbox, calendar and distribution list against a checklist before calling a migration complete.
A named contact throughout your migration, not a ticket queue you have to explain your situation to repeatedly.
Managed plans include cloud backup for Microsoft 365 data, protecting mailboxes beyond Microsoft's default retention.
Local PST archives are imported with folder structure intact, not dumped into a single unsorted folder.
The same team managing your migration also supports Exchange Online afterwards, under your existing IT plan.
A clear quote agreed after the audit, so there are no surprise charges once the migration is under way.
The cost of an Exchange Online migration depends on the number of mailboxes, the total data volume, and how complex your existing distribution lists and permissions are. Straightforward migrations for a small office with a handful of mailboxes are typically quick and low-cost; larger organisations with complex shared mailbox structures and PST archives take longer to plan and test properly. Our managed IT plans start from £20 per user per month and can bundle Exchange Online support and cloud backup together. We scope an exact, fixed quote after the initial audit rather than publishing a generic price list that won't reflect your setup — get in touch for a free consultation and a clear migration plan.
The most common failure point in a rushed migration is DNS records switched before verifying that mailboxes are actually provisioned and receiving mail correctly in Exchange Online — a premature MX change can mean incoming email bounces or gets delayed for hours while the sending server's records are stale. The second most common issue is distribution lists and shared mailboxes copied across in outline but never tested with a real email, so a group address that used to reach the whole sales team silently goes nowhere after cutover and nobody notices until a customer complains about no response. The third is PST archives left behind entirely, either because nobody flagged them during the audit or because importing them felt like an optional extra — years of email history then effectively become inaccessible once the old mailbox is decommissioned. We plan around all three as standard, which is why our migrations rarely produce the kind of horror stories that prompt businesses to search for a proper exchange online migration service in the first place.
Migration providers vary enormously in how thoroughly they scope a job before starting, and that difference shows up directly in how smooth your cutover actually feels. Ask specifically how DNS and MX record changes are sequenced — a migration that switches MX records before mailboxes are actually ready in Exchange Online is a common cause of lost or delayed email. Ask whether distribution lists, shared mailboxes and delegate permissions are recreated as standard, or treated as an optional extra.
Timing matters: plan a migration around your business calendar, not the provider's availability, and confirm the old system stays available during the transition in case anything needs more time.
Getting started: we offer a free consultation and environment audit before any commitment, so you know exactly what a migration involves and what it will cost before agreeing to anything.
Ask about rollback: a good migration plan always includes a way back to the old system if something unexpected comes up on cutover day, not just a forward-only plan that assumes everything will go perfectly.
