Move without the mess
Office 365 Migration
Moving your email and files to Office 365, which Microsoft now calls Microsoft 365, is a solved problem. Companies still botch it weekly. The difference is planning, and a team that has done the cutover enough times to know where it bites.
What we migrate from
Google Workspace is the most common starting point, followed by on-premise Exchange servers that have earned their retirement. We also move aging POP and IMAP hosting, other tenants after a merger or acquisition, and the awkward hybrid setups a previous provider left half-finished. Mail, calendars, contacts, shared mailboxes, distribution groups and files all come across, with permissions intact.
How an Office 365 migration actually goes
First an assessment, where we count mailboxes, measure data, and find the things nobody mentioned, like the scanner that emails through the old server or the alias the owner forgot exists. Then a pilot group proves the process on a few real users. Then staged syncing moves the bulk of the data quietly in the background over days, while everyone keeps working. The cutover itself usually lands on a Friday evening, and by Monday morning mail flows to the new home with the old system still readable as a safety net.
Microsoft documents the mechanics thoroughly in its own migration guidance. The mechanics are not the hard part. Sequencing, DNS timing, and the hundred small user-facing details are.
What goes wrong when it is rushed
Mail silently bouncing for hours because DNS changed in the wrong order. Shared mailboxes arriving without their permissions, so accounting cannot open invoices on Monday. Calendar invites detached from their meetings. The one printer that could scan to email, suddenly mute. Old phones still pulling from the dead server. None of these are exotic. All of them are preventable, and preventing them is most of what you are paying for. A planned Office 365 migration makes them non-events.
What an Office 365 migration costs
Pricing follows mailbox count and source complexity rather than drama. A clean Google Workspace tenant with twenty users is a very different job from a fifteen-year-old Exchange server with public folders and a departed admin, and the assessment tells us which one you have before anyone quotes a number. Licensing is the other half of the conversation: most companies discover they are paying for a heavier plan than they use, and right-sizing licenses during the move often covers a meaningful slice of the project cost.
Timeline runs from about a week for small, tidy tenants to a month for layered ones, with almost all of it invisible to your team. The only moment users notice is the cutover weekend, and the Monday after a well-run Office 365 migration is famously boring: people log in, mail is there, files open, and the help desk phone stays quiet. If Monday is not boring, we are on it before your staff finish their coffee, with the old system still readable as the fallback. Licensing gets rightsized in the same pass, so you stop paying for seats nobody uses, and you leave the project with a clear map of who owns what in the new tenant.
After the cutover
We do not leave at go-live. Security defaults get set properly, multi-factor authentication comes on from day one, and mailbox rules that attackers love to abuse are locked down. Then the licenses you are now paying for start earning their keep through Microsoft 365 support, and if the move is part of a wider platform change, technology migration covers the rest of the estate beyond email.
