Can deleted e-mails or files be recovered?

Often, yes. Deleted e-mails and files can frequently be recovered through server backups, mailbox retention windows, shadow copies and forensic imaging of drives, but the window narrows quickly, because systems overwrite freed space over time. That is why preservation should begin the moment a suspicion arises: a legal hold stops routine deletion and log rotation, and forensic imaging captures the data with a verifiable hash so it stands up later. How recovery is carried out also matters. To be usable in court in Türkiye under the Code of Civil Procedure (HMK, Law 6100), evidence must be obtained lawfully; where employee accounts are involved, the review must also respect the Personal Data Protection Law (KVKK, Law 6698). We can coordinate the preservation and forensic steps within these limits.
