Exchange Online Migration and Management

Exchange Online migrations are one of the most common projects we deliver. Organisations come to us running Exchange 2013 or 2016 on premises, sometimes older, and need to move their email to Microsoft 365 without losing a single message or disrupting daily operations.

The migration itself is the straightforward part. What separates a good Exchange project from a painful one is the preparation: mailbox sizing, identifying shared mailboxes and distribution lists that need restructuring, mapping calendar delegates, testing mail flow rules, and planning the DNS cutover so users wake up on Monday morning with everything working.

We also handle migrations from non Microsoft platforms: Google Workspace, Lotus Notes, Zimbra, and hosted POP3/IMAP services. These tend to be more complex because calendar and contact formats do not always map cleanly, but we have dealt with enough of them to know where the problems hide.

Beyond migration, we configure Exchange Online security properly. That means anti-phishing policies, Safe Links, Safe Attachments, DKIM/DMARC/SPF records, and conditional access policies that prevent email access from unmanaged devices. Most organisations we assess have at least two or three security gaps in their Exchange configuration that they did not know about.

Evocate provides ongoing managed services for Exchange Online including mailbox monitoring, quota management, security policy updates, and helpdesk support. Call 1300 386 228 to discuss your email environment.
