What it is

Stellar Repair for Outlook is desktop software for repairing corrupted Outlook PST files and recovering mailbox data. It can recover emails, attachments, contacts, calendars, tasks, notes and journals, including deleted items, which it marks in red. Users can preview recoverable items and filter emails before saving. The maker says it handles PST files of any size, including encrypted or password-protected files, and works in read-only mode so the original PST is not modified. Recovered data can be saved as PST, EML, MSG, RTF, HTML or PDF. A licensed Microsoft Outlook installation is required to complete desktop repair and save to a new PST. The desktop trial can scan and preview items but cannot save recovered data; 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. The free online plan covers one PST up to 500 MB with a download available within 24 hours; Premium costs $29.99, paid once per file for one PST over 500 MB and up to 5 GB, with a 48-hour download window.

Stellar Repair for Outlook in depth

Read the full write-up

Stellar Repair for Outlook is a PST-repair tool for recovering Outlook mailbox data, offered as Windows software and a separate browser service. It is best suited to people who need to inspect and selectively save recoverable items; the desktop option is the stronger fit for large or repeated jobs, while online recovery is bounded by file size and download windows.

Overview

The desktop product recovers 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 on relevant material instead of exporting everything. Read-only operation preserves the original PST, an important safeguard when the source file is already damaged.

Stellar says the desktop software 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. Batch recovery is supported. Technician edition can export repaired mailbox items directly to Microsoft 365 or Live Exchange, which makes it the relevant desktop tier for administrators placing recovered data back into a live service.

Key features

Selective recovery: Preview and email filters help narrow what gets saved; deleted items are visually marked for identification.

Multiple output formats: Six save formats accommodate Outlook use as well as more portable or document-oriented access.

Local handling: Desktop repair runs read-only and leaves the original PST unmodified.

Browser recovery: The online service runs in Chrome, Firefox, Edge, Safari and other major browsers without local installation. Stellar says uploads are processed over a secure connection without a human touchpoint and deleted after 24 hours on Free or 48 hours on Premium.

Pricing

The desktop trial can scan and preview recoverable items but cannot save them, so it is useful for checking whether the data is recoverable, not for completing a recovery without buying. Desktop plan prices include Professional at $99, paid once, Technician at $199, paid once and Toolkit at $499, paid once; each is described as supporting unlimited file size. Technician is the tier to choose for direct Microsoft 365 or Live Exchange export. Toolkit is the highest-priced tier, but the plan facts do not distinguish its additional capabilities.

A separate Professional (desktop) price is $79 as a one-time purchase, with billing interval not stated; it includes unlimited PST file size, unlimited files and local repair. That lower price is distinct from the 99.00 USD Professional plan, so buyers should confirm which offer and terms apply before purchase. The product also offers online plans: Free costs nothing, requires no credit card and covers one PST up to 500 MB, with download within 24 hours. Premium costs $29.99, paid once, billed per file, for one PST over 500 MB and up to 5 GB, with download within 48 hours. Online recovery suits an occasional single-file job; its per-file charge and capped size make it less compelling for larger or repeated recovery.

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 to a new PST. The browser service avoids those local software requirements, although its one-file size and download-window limits still apply.

Who it's for

Choose Stellar when Outlook users need to recover several kinds of mailbox items, inspect results before export, or preserve the original PST during repair. The desktop route fits people with compatible Windows hardware and licensed Outlook, particularly those handling large files or recurring work. The browser option is more convenient for a one-off file within its size cap. It is not the right desktop choice for someone without Outlook or supported Windows, or for anyone who needs to save from the trial before paying.

Pros and cons

Pro: Preview, filtering and red marking of deleted items provide useful control over what gets recovered.

Pro: Read-only repair protects the source PST, while six export formats cover several downstream uses.

Pro: The online Free tier handles one PST up to 500 MB without a credit card.

Con: Desktop repair and saving require both a supported 64-bit Windows system and licensed Outlook, in addition to at least 8 GB of memory.

Con: The desktop trial cannot save data, and the online service limits file size, file count and download availability time.

Con: The separate 79.00 USD and 99.00 USD Professional desktop prices have different stated terms, so the purchase choice is not straightforward.

Alternatives

Email Recovery Software is a useful starting point for comparing recovery tools. Consider Recovery Toolbox for Outlook if its 39.00 USD personal or 59.00 USD business one-time license and broader listed platform coverage better suit your needs. BitRecover Exchange Recovery is worth considering when a free tier limited to 25 items per folder is enough to assess an Exchange recovery. Exchange EDB Recovery Tool has a free version with a 25-item-per-folder saving and migration limit, making that cap a relevant trade-off for a small recovery.

WholeClear Exchange Recovery is another Exchange recovery option. PST Walker may suit personal users who can work within its Lite license: $32.95 a year, paid once, with viewing and export of up to 15 emails per folder and no updates. For mailbox migration rather than this product's recovery workflow, EdbMails IMAP Migration Tool has a $200, paid once plan for 100 mailboxes across listed IMAP, Exchange, Office 365 and PST routes. MailXaminer is another paid Windows option. Recoveryfix OST to PST may fit a personal user who needs OST-to-PST conversion on one machine, with its listed 39.00 USD one-time license valid for one year.

Verdict

Stellar Repair for Outlook is a sound choice for Outlook users who need selective recovery, broad export options and a read-only repair process, especially when desktop file-size flexibility or Technician's direct Microsoft 365 and Live Exchange export matters. Look elsewhere if you lack licensed Outlook or compatible Windows, need the trial to save data, or want a browser job beyond the online limits.

Verdict

Stellar Repair for Outlook offers desktop recovery with preview and filtering, alongside a browser-based service. Check the desktop requirements and trial save restriction, or the online file-size and download-window limits, before selecting an option.
