// field log — security firm, 500+ users
No mail server. No timeline. No problem.
A global security firm of 500+ people lost their hosted mail server to ransomware — with no recovery timeline from the provider. Every employee, cut off from email.
// the situation
The only surviving data was scattered PST and OST files sitting on individual computers across the organization. Client communication and daily operations were dead in the water.
// what we did
Restored email for the highest-impact users first while standing up a complete Microsoft 365 environment in parallel. Systematically recovered historical mail from local files across the company and deployed Exchange Online with security policies fit for a security firm — all while the original server stayed dark.
// results
> Critical teams back on email within days.
> All 500+ users migrated to Exchange Online — history included.
> Zero dependency left on the compromised infrastructure.
