Frequently Asked Questions

Ans: Yes. The SysInfo OST Recovery Tool performs all recovery operations locally on the host system without transmitting mailbox data to external servers. Since the recovery process is conducted entirely offline, it ensures complete data confidentiality and aligns with enterprise security, privacy, and compliance requirements.

Ans: Yes. The SysInfo OST Recovery Tool is designed to process large and oversized OST files without imposing file size restrictions. It can efficiently recover enterprise-grade OST files exceeding 50 GB, including files larger than 80 GB, while preserving mailbox structure and data integrity throughout the recovery process.

Ans: Yes. The tool can recover OST files stored on internal drives, external USB devices, network locations, and backup media, provided the OST file is accessible through the Windows file system. If the storage device is physically damaged or the OST file cannot be accessed, the storage medium must first be restored using appropriate disk, RAID, or storage recovery solutions.

Ans: The current version does not include a dedicated email deduplication engine. However, administrators can perform selective recovery using Date Range filters, folder selection, and advanced Search options to exclude duplicate or unnecessary mailbox items before exporting the recovered data.

Ans: The SysInfo OST Recovery Tool is available in Single User, Administrator, Technician, and Enterprise editions. Each license is designed to accommodate different deployment requirements, ranging from individual workstations to large-scale enterprise environments.

Ans: SysInfo OST Recovery Tool supports OST files created by Microsoft Outlook 2003 and later, including the latest Outlook versions. It automatically detects the OST file format and applies the appropriate recovery method, ensuring seamless recovery across mixed Outlook environments without requiring manual configuration.

Ans: SysInfo OST Recovery Tool offers Standard, Advanced, and Deep Recovery modes to handle different levels of OST corruption. Standard Recovery is recommended for minor corruption; Advanced Recovery is suitable for moderate corruption such as synchronization or indexing issues; and Deep Recovery performs a comprehensive scan for severely corrupted or inaccessible OST files. Deep Recovery should be used only when Standard or Advanced Recovery does not provide satisfactory results, as it requires additional processing time.

Ans: Yes. SysInfo OST Recovery Tool can recover deleted emails, contacts, calendars, tasks, notes, journals, and other mailbox items that still exist within the OST database. Recoverable items are displayed in the preview before saving. However, if the data has been permanently removed or overwritten within the OST file, recovery may not be possible.

Ans: Yes. SysInfo OST Recovery Tool supports the recovery of encrypted OST files. Since OST files are associated with Outlook profiles and Windows user accounts, access depends on the integrity of the OST file and the corresponding Outlook profile. If the Outlook profile or Windows account credentials are unavailable, additional authentication may be required before accessing mailbox data.

Ans: No. The SysInfo OST Recovery Tool does not provide direct export of recovered mailbox data to Microsoft 365 or Exchange Server. It allows you to save the recovered mailbox in PST, MSG, EML, MBOX, DBX, or Archive format, which can then be imported into Microsoft 365 or Exchange Server using Microsoft's native import utilities. Alternatively, if you need to view OST or migrate it directly to Microsoft 365, you can use a dedicated OST management solution.

Ans: Yes. The tool preserves the original folder hierarchy, email metadata, timestamps, attachments, categories, read/unread status, flags, and other mailbox properties throughout the recovery process.

Ans: SysInfo OST Recovery Tool allows users to generate and save a detailed TXT log report of the recovery process. The log contains information such as the selected OST file, recovery start date and time, recovery mode, processing status, scanned folders, and any errors encountered during recovery. These logs assist administrators with auditing, troubleshooting, and maintaining recovery documentation.

Ans: Yes. The tool supports both 32-bit and 64-bit editions of Microsoft Outlook and is compatible with all major Windows operating systems, making it suitable for enterprise deployment.
