Case Study: Crowe Clark Whitehill achieves secure, UK-hosted cloud email archiving and major cost savings with Mimecast

Moving Crowe Clark Whitehill to a Cloud-Based Archiving Solution

Crowe Clark Whitehill is a leading UK accountancy firm with 650 employees across seven offices that needed to migrate its email platform from IBM Lotus Domino to Microsoft Exchange. The IT team faced a choice between costly on‑premises archiving that would require extra headcount and a Microsoft cloud option that risked storing data outside the EU, which would conflict with UK data‑protection requirements.

Working with UK partner Applicable, the firm deployed Mimecast UEM Enterprise as a managed, UK‑hosted cloud archiving, continuity and security solution. Mimecast archived emails and attachments older than one year to speed migration, eliminated multiple third‑party systems, provided 24/7 support and consistent security policies, and enabled 10‑year retention with eDiscovery for users. The move avoided major hardware purchases, reduced complexity and delivered significant cost savings while meeting regulatory requirements.
