Stellar Repair for Outlook

Stellar Repair for Outlook is desktop software for repairing corrupted Outlook PST files and recovering mailbox content. It can retrieve emails, attachments, contacts, calendars, tasks, notes, and journals, including deleted items, which it marks in red. Users can preview recoverable content and filter emails before saving. The maker says it handles PST files of any size, including encrypted or password-protected files, and runs in read-only mode without changing the original. Recovered data can be saved as PST, EML, MSG, RTF, HTML, or PDF. A licensed Microsoft Outlook installation is required to finish desktop repair and save to a new PST; the desktop trial scans and previews but cannot save. Desktop use requires 64-bit Windows 11, 10, 8.1, or 8 and at least 8 GB of memory. A browser-based service is also available without local installation. Online options include a free plan for one PST up to 500 MB and a $29.99 per-file Premium option for one PST over 500 MB and up to 5 GB.

The product offers desktop PST repair and a browser-based option, with previews and several export formats. Check the Outlook and Windows requirements before choosing desktop repair.

It suits Outlook users who need to recover mailbox data from a corrupted PST file and want to preview items before saving. Desktop use requires a licensed Outlook installation and a supported 64-bit Windows system.

Stellar Repair for Outlook is a PST-repair product with a Windows desktop app and a separate browser service. It best suits Outlook users who need to recover and selectively export mailbox data; the main caveat is that desktop repair requires both compatible Windows hardware and licensed Outlook.

Overview

The desktop software can recover emails, attachments, contacts, calendars, tasks, notes and journals, including deleted items, which it marks in red. Previewing results and filtering emails before saving let users focus an export on the material they need. Read-only operation avoids changing or overwriting the original PST, a useful safeguard when working with damaged mail files.

Stellar says the desktop product handles PST files of any size, including encrypted or password-protected files. Recovered data can be saved as PST, EML, MSG, RTF, HTML or PDF. The Technician edition can also send repaired mailbox items directly to Microsoft 365 or Live Exchange, which is more practical for administrators restoring data to a live service than exporting a file first.

Key features

• Mailbox recovery: The range of recoverable items extends beyond email to calendars, contacts, tasks, notes and journals; deleted items are visually marked for identification.
• Selective recovery: Preview and email filters help avoid saving unwanted material. Batch recovery is supported for larger jobs.
• Multiple exports: Six output formats cover Outlook-compatible PST files as well as portable document and message formats.
• Browser option: The online service runs in Chrome, Firefox, Edge, Safari and other major browsers without installing desktop software.
• Upload handling: The service says files travel over a secure connection, are processed without a human touchpoint, and are deleted after 24 hours on Free or 48 hours on Premium. Those windows matter if a recovery cannot be downloaded promptly.

Pricing

The desktop trial can scan and preview recoverable items but cannot save them, so it helps assess whether the expected data appears without providing a usable recovery on its own. Desktop paid plans are one-time purchases: Professional is $99, paid once, Technician is $199, paid once, and Toolkit is $499, paid once. Each lists unlimited file size. Technician is the clearest fit when direct export to Microsoft 365 or Live Exchange is needed; Professional suits local PST recovery without that stated integration. Toolkit is the highest-priced tier, but no additional capabilities are described here to distinguish it.

The browser Free plan costs nothing, requires no credit card, and covers one PST file up to 500 MB, with download available within 24 hours. Premium costs $29.99, paid once, billed per file, and handles one PST file over 500 MB and up to 5 GB, with a 48-hour download window. These are straightforward choices for a one-off recovery within the relevant size band, but the per-file charge and single-file limit make them less suitable for repeated or bulk work.

A separate Professional (desktop) offer is priced at $79, paid once and includes unlimited PST file size, unlimited files and local repair.

Platforms

The desktop software requires 64-bit Windows 11, 10, 8.1 or 8 and at least 8 GB of memory. A licensed Microsoft Outlook installation is also required to complete repair and save recovered data as a new PST. That makes the desktop route a poor fit for users without Outlook or a supported Windows PC. The online service avoids those local requirements, but imposes its own size, per-file and download-window limits.

Who it's for

Choose Stellar when a damaged PST contains multiple kinds of mailbox data, when selective preview matters, or when you want several export formats and a read-only repair process. It is also a sensible fit for organizations using Technician's direct Microsoft 365 or Live Exchange export. Users with one smaller file can start with the free browser option; those with larger one-off files can consider Premium. Look elsewhere if you need desktop saving without licensed Outlook, a non-Windows desktop workflow, or more flexibility than the online file and time caps allow.

Pros and cons

• Pro: Preview, filters and red-marked deleted items make it easier to identify what to recover before saving.
• Pro: Read-only operation preserves the source PST, while six export formats support different follow-up workflows.
• Pro: The browser service provides a no-install route, including a free option for one file up to 500 MB.
• Con: Desktop completion requires licensed Outlook and 64-bit Windows with at least 8 GB of memory.
• Con: The trial cannot save recovered data, so recovery itself requires a paid plan.
• Con: Online recovery is limited to one file per plan, with a 5 GB ceiling on Premium and short download windows.

Alternatives

Recovery Toolbox for Outlook is worth comparing for its $39, paid once Personal License or $59, paid once Business License, particularly when those license terms better fit the intended use. BitRecover Exchange Recovery has a free tier capped at 25 items per folder, a useful starting point if that ceiling is sufficient. Exchange EDB Recovery Tool also has a free version with a 25-item-per-folder saving and migration limit. PST Walker offers a $32.95 a year Lite License described as a one-time payment for a one-year, personal-use license, with viewing and limited export rather than unrestricted recovery. WholeClear Exchange Recovery is another option to compare for its Linux, macOS and Windows platform support. DataNumen Outlook Repair is a paid Windows alternative with a free trial and no free plan. DataNumen Exchange Recovery is a paid Windows option with a trial and a listed one-user license price of $199.95, paid once. EdbMails EDB Recovery is a Windows alternative with a Personal Edition priced at $99, paid once.

Browse the broader Email Recovery Software category if none of these fits the recovery job.

Verdict

Stellar Repair for Outlook is a strong match for Outlook users who need selective PST recovery, broad mailbox-item coverage and flexible exports, especially when Technician's direct Microsoft 365 or Live Exchange export is useful. Its main reason to look elsewhere is the desktop dependency on Windows and licensed Outlook; for a small one-off file, the browser service is more convenient but tightly limited by size, file count and download time.
