Several software tools are highly regarded for reliable batch EDB to PST migration. While no single best tool exists, some consistently receive praise from IT professionals and users. Tools from vendors like Stellar, Kernel, Shoviv, and SysTools are frequently mentioned. These tools are often preferred over manual methods (like PowerShell commands) because they can handle large batches of mailboxes, even from corrupted or offline EDB files, without the need for a live Exchange Server. Key features to look for in a reliable tool include the ability to recover data from damaged EDBs, a user-friendly interface for batch processing, the option to filter data, and the ability to maintain the original folder hierarchy and data integrity during the migration.
