Our Story

25 years of Exchange infrastructure

We started as Christensen Software in December 2000 with a single mission: solve real email infrastructure problems for IT administrators running Microsoft Exchange Server. In December 2025, we moved distribution to Servolutions IP Corporation — same team, same commitment, sharper focus.

Our approach has always been the same: build software that installs in minutes, requires minimal configuration, and then runs reliably for years. No bloat, no cloud dependency, no subscription lock-in for on-premise tools. When something breaks, you reach the developers directly.

Today our product suite spans POP3/IMAP connectors, outbound SMTP routing, and Outlook add-ins for Exchange Server — plus MailSync Hub, our new cloud sync product for Microsoft 365 environments.

How We Work

What we believe about software

Reliability over features

A product that runs for five years without incident is worth more than one with twenty checkboxes that occasionally fails. We build for uptime.

Direct support, no queues

When you have a problem, you talk to someone who can actually fix it. Not a tier-1 script reader — the engineers who wrote the code.

Honest licensing

On-premise products are one-time per-server license. No per-user fees, no forced upgrades, no subscriptions for software that runs on your hardware.

Questions? Contact us directly.

We're a small company. When you email us, you hear back from the people who built the product.
