Simple investigations involving a single email account and straightforward questions may be completed within 1-2 weeks. More complex investigations involving multiple users, various communication platforms, and detailed analysis requirements typically take 4-8 weeks to complete.
Large-scale investigations involving enterprise-wide communication systems, multiple jurisdictions, or complex legal requirements may require several months to complete thoroughly. We work closely with clients to establish realistic timelines based on the specific requirements of each case.
Recovery of deleted emails and messages is often possible, but success depends on several technical factors including the time elapsed since deletion, the specific email system or messaging platform involved, and the level of system activity since the deletion occurred.
Email systems typically maintain deleted items in recoverable folders for periods ranging from 30 days to several months, depending on system configuration. Even after purging from these folders, data may remain recoverable from backup systems, server logs, or unallocated storage space.
Messaging applications present varying levels of recovery possibility. Some platforms maintain comprehensive server-side logs while others implement more aggressive deletion policies. Our forensic specialists employ advanced recovery techniques tailored to each platform's specific characteristics.
The key to successful recovery is prompt action to preserve evidence before it can be overwritten by normal system operations. We recommend immediate consultation when deleted communication recovery is required.
