Case Study: Lagan Group achieves near-zero email downtime and fast e-discovery with Mimecast

Mimecast provides Lagan Group with Email Safety Net for Office 365

Lagan Group, a diversified construction and manufacturing company supporting 450 email users across 52 sites, relied on email as a critical business tool but had suffered outages and was moving from on‑prem Exchange to Office 365. While Office 365 offered 99.9% uptime, the IT team needed near‑zero downtime, a fully compliant searchable archive, mobile access to historical mail, and stronger security.

They implemented Mimecast’s Unified Email Management/Email Safety Net alongside Office 365, gaining a 100% continuity SLA, a perpetual cloud archive searchable from any device, mobile archive access, and robust anti‑spam/anti‑virus protection. The result: downtime concerns eliminated, e‑discovery completed in minutes, noticeable productivity gains (one user reported ~40 minutes saved per day), reduced IT stress and the freedom to focus on strategic projects.
