Cost-effective routing between M365 and private local servers — premium cloud mailboxes for the people who need them, economical local mailboxes for everyone else.
Pay cloud prices only for the mailboxes that genuinely need cloud features.
Everyone stays @yourcompany.com — senders and recipients never see the difference.
Notification, scanner and system accounts without per-seat fees.
Not every user needs a full Microsoft 365 mailbox. A hybrid setup gives your leadership and client-facing teams M365, while warehouse, factory-floor or high-volume notification accounts live on a private mail server at a fraction of the cost — all under one domain, completely invisible to the outside world.
Like everything we do at V12, this comes with our family-run promise: honest advice, transparent pricing, and zero-jargon support from the same engineers who built your system.
Inbound mail is routed per-mailbox to M365 or your local server — automatically and reliably.
TLS-only, fail2ban-protected, properly authenticated private mail that stays off blacklists.
Shared global address list and smooth internal mail between cloud and local users.
Multi-layer spam and malware filtering on both legs of your mail flow.
IMAP/ActiveSync for local mailboxes — mail, contacts and calendars on any phone.
Promote a user to M365 (or back) in minutes as roles change — no address changes ever.
We classify every mailbox: who needs Teams and shared calendars, who just needs reliable email.
Routing topology, server sizing and security policy are mapped and costed transparently.
The local platform is built, DNS updated, and split routing enabled with careful testing.
Deliverability is monitored for weeks after go-live; filters and policies tuned to your traffic.
