On-Premises Exchange to Microsoft 365 Migration — Saudi Arabia

Many Saudi organisations are still running on-premises Exchange Server — 2013, 2016 or 2019 — that is now costly to patch, harder to secure, and approaching end of support. Moving to Microsoft 365 (Exchange Online) removes the server maintenance burden, modernises email security, and unlocks Teams, SharePoint and OneDrive, but a botched migration means lost mail, broken Outlook profiles, and angry users on Sunday morning. The migration itself is the hard part: choosing the right method, keeping mail flowing during cutover, preserving calendars, shared mailboxes, public folders and permissions, and getting DNS and identity right.

Skyline plans and executes Exchange-to-Microsoft 365 migrations end to end. Our engineers assess your environment and mailbox sizes, then select the right approach — cutover for smaller estates, staged or full hybrid (with Entra Connect identity sync) for larger ones that need coexistence and a phased cutover with minimal user impact. We migrate mailboxes, archives, shared mailboxes, distribution groups and public folders, import legacy PSTs, reconfigure Outlook and mobile (including ActiveSync), update MX and autodiscover DNS, and harden the result with Exchange Online Protection and modern authentication. We can also advise honestly when a Saudi-resident email platform better suits your data-residency needs than the global cloud.

• Method selection: cutover, staged, or hybrid with identity sync — matched to your size and risk tolerance.
• Zero-surprise cutover: mail flow, calendars, shared mailboxes, public folders and permissions all preserved.
• Clean DNS and identity: MX, autodiscover, SPF/DKIM/DMARC, and Entra Connect done correctly.
• Post-migration hardening: email security, modern auth, Outlook and mobile reconfigured.

We deliver across Riyadh, Jeddah, Dammam, Khobar and the GCC, with a clear runbook and rollback so the business keeps emailing throughout.
