cPanel to Office 365 Migration
cPanel-hosted email (Bluehost, HostGator, SiteGround, Namecheap, any cPanel host) → Microsoft 365. Mail and folders move server-side; your website, FTP, and databases stay exactly where they are. Only mail routing changes. From $15/user.

Every mailbox. Every folder. Verified.
What staying actually costs.
Shared-host IPs live on blacklists you’ve never heard of. Your quotes land in spam because someone else on the same server runs a newsletter cannon.
cPanel hosts cap mailboxes and inodes. Microsoft 365 gives 50 GB primary + archive — the storage ceiling disappears in passing.
cPanel/Roundcube has no server-side calendar or contact sync. Your business runs on personal phone contact lists. M365 fixes the actual problem.
The MX flip in cPanel’s Zone Editor takes minutes; propagation 1-4 hours. Website, FTP, databases — untouched.
Everything handled. Nothing assumed.
Server-side IMAP sync
Every cPanel mailbox syncs to Microsoft 365 in the background over IMAP — overnight batches so shared-host rate limits never stall the project.
Forwarders, aliases, catch-alls
The classic missed items. We inventory every forwarder, alias, and catch-all in cPanel and recreate them as Microsoft 365 rules and aliases before cutover.
Website stays put
Only MX, SPF, and DKIM records change in the Zone Editor. Your website, FTP accounts, and databases stay on the host exactly as they are.
Webmail contacts runbook
Roundcube/Horde contacts export per-user — we provide the guided runbook and verify the imports landed.
Deliverability reset
Leaving the shared IP means SPF, DKIM, and DMARC configured properly on Microsoft 365 — your mail reputation finally belongs to you.
Old-mailbox decommission
After verification we disable the cPanel mailboxes to prevent split delivery — the failure mode DIY migrations always hit.
Assess. Plan. Migrate. Cutover.
Assess
1-2 days · Source audit, mailbox inventory, domain list. Fixed per-user quote in 24-48 hours.
Plan
1-2 days · Microsoft 365 tenant provisioned, domains verified, MFA + security baseline deployed.
Migrate
Background · Server-side pre-stage sync runs invisibly. Users keep working on the old system until cutover.
Cutover
2-4 hrs off-hours · MX/SPF/DKIM flip, final delta sync, Autodiscover repoint. 30 days hypercare.
The engineers on your project.
No outsourced ticket triage. The same three engineers handle source assessment, tenant provisioning, cutover night, and post-migration support on every cPanel engagement.

The cPanel-specific realities.
Generic migration guides skip these. They are the operational details that decide whether your cutover weekend is boring — which is the goal.
Shared-host IMAP is slow and connection-capped — overnight batch pacing keeps the host from rate-limiting the sync
cPanel has no server-side calendars/contacts (webmail-only data) — users export those individually with our runbook
Catch-alls and forwarders hiding in cPanel are the classic missed item — we inventory them before cutover, not after mail goes missing
