Microsoft 365 Migration

Email migration to Microsoft 365 - without losing a single message.

From Gmail, Zoho, Rediffmail, GoDaddy or your aging on-prem Exchange - we move your mailboxes, contacts, calendars and shared aliases to Microsoft 365 over a planned weekend cutover.

You don’t fear “the migration.” You fear losing emails.

Every owner who calls us about email is really worried about the same five things. We’ve handled all of them — quietly, on a weekend, with zero data loss.

  • “Will anyone lose old emails or attachments?”
  • “What if my domain breaks and customers can’t reach us Monday?”
  • “What about shared mailboxes, distribution lists and aliases?”
  • “Will my team have to reconfigure Outlook on every laptop and phone?”
  • “Is Microsoft 365 actually cheaper than what we have today?”
Built for: 5–500 mailboxes Schools / NGOs Multi-location SMBs

FAQs

Will my users lose email during the cutover?
No. We perform two delta syncs before the cutover and a final delta sync immediately after. Any in-transit mail is queued by the source server and delivered to Microsoft 365 once MX flips.
How long does the project take?
A 10-mailbox migration typically wraps in 5-7 working days. A 50-user project takes 2-3 weeks including training. Larger or hybrid projects are scoped per phase.
Do we need to buy Microsoft 365 licences from Intrys?
No - we'll happily migrate to a tenant you already own. But buying through us bundles licence + project on a single GST invoice and unlocks our 14-day hypercare for free.
What about archived mail and shared drives?
Mail archives migrate to Online Archive in Exchange Online (50-100GB depending on plan). Shared drives can move to OneDrive or SharePoint - quoted separately.
Is data residency in India guaranteed?
For tenants provisioned in the India data region, your mailbox data is stored in Microsoft's Pune and Chennai data centres - in line with the DPDP Act, 2023.
