What does a Microsoft 365 email migration involve?
A Microsoft 365 email migration means moving your business email from your existing provider — such as a hosting company's webmail, Google Workspace, or an old Exchange server — to Microsoft 365 (formerly Office 365). The process involves transferring mailbox data, updating DNS records so that new email routes through Microsoft's servers, and verifying that everything is working correctly afterwards.
Done poorly, email migrations cause lost emails, spam delivery failures, and disruption to the business. Done properly, the cutover is seamless — users continue receiving email with no gaps in history.
London PC Fix handles M365 email migrations for small businesses across London, including all DNS changes, mailbox transfers, and post-migration testing.

Email Migration — Common Questions
Can you migrate our business email to Microsoft 365?
Yes. We migrate London businesses from hosted email providers, Google Workspace, and legacy Exchange to Microsoft 365, handling the technical process from DNS configuration to mailbox transfer.
Will we lose emails during the migration?
No. We plan migrations carefully to preserve email history and minimise disruption. We test delivery before and after the cutover and prefer to migrate during low-traffic periods.
How long does a Microsoft 365 email migration take?
For most small businesses with 5–15 users, the technical migration takes a few hours. Planning and preparation add time. DNS changes take up to 24–48 hours to propagate fully across the internet.
Do you handle the DNS changes?
Yes. We manage all the DNS changes needed for email delivery, including MX records, SPF, DKIM, and DMARC. We can guide you through the changes at your domain registrar or make them directly if you provide access.
What if something goes wrong after migration?
We provide post-migration support to resolve any issues that appear after the cutover — missed email, spam filtering problems, calendar sync issues, or mobile device configuration.
