Case Study: Currie & Brown achieves a secure Office 365 migration and seamless access to legacy email with Mimecast

Currie & Brown Secures Office 365 Migration with Mimecast

Currie & Brown, a global physical‑assets management and construction consultancy with about 700 email users, migrated from on‑premise Novell GroupWise to Office 365 but faced several challenges: no seamless access to legacy GroupWise mail, weakened anti‑spam/anti‑malware protection, limited long‑term archiving and resilience, and growing mailbox/Outlook performance issues.

They deployed Mimecast Unified Email Management to ingest the legacy archive, provide unified search across historical and Office 365 mail, and restore stronger security and continuity. The result was immediate access to historical email, AS/AV issues resolved from day one, reduced on‑prem storage and compute costs, improved mobile and desktop search, and overall better user productivity and resilience.
