ESI Collection+

Defensible Collection of Web-Based Email

Lexbe’s ESI (electronically stored information) Email Collection+ service defensibly collects web-based email archives in preparation for eDiscovery processing, review, and production.

Email collections can represent a significant portion of the ESI in a case today, and web-based corporate, business, and consumer email services are becoming increasingly popular for personal and professional communication. The challenge presented by this trend is in defensibly collecting custodian (email user) web-based email files and preparing them for eDiscovery review.

With ESI Email Collection+, we securely collect web-based custodian IMAP (web email storage folder) email archives and process them into standard Outlook PST format in preparation for further eDiscovery processing and review. Also included with this service are detailed collection and chain of custody reports that fully document our procedures and support evidence admissibility. Avoid the perils of email collection and let us apply our electronic discovery and forensic expertise to deliver precisely what you need to quickly and accurately review email evidence.
