Stellar Repair for Outlook

Stellar Repair for Outlook is a PST-repair tool for people trying to recover mailbox data from a damaged Outlook file. It best suits Outlook users who need to review and selectively export recovered items, or administrators who need Technician’s direct Microsoft 365 or Live Exchange export. Its choice between local repair and a limited browser service is useful, but the desktop route depends on compatible Windows hardware and licensed Outlook.

Overview

The desktop software recovers emails, attachments, contacts, calendars, tasks, notes and journals, including deleted items, which it marks in red. Previewing results and filtering emails before saving give users a way to narrow what they export. Because it works read-only, the original PST is not modified or overwritten.

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. Batch recovery is supported. The Technician edition also exports repaired mailbox items directly to Microsoft 365 or Live Exchange, which is more useful for administrators who need to restore data to a live service than for someone who only needs a local file.

Key features

• Selective recovery: Preview and email filters help users inspect results and choose what to include or exclude before saving.
• Multiple output formats: PST, EML, MSG, RTF, HTML and PDF accommodate Outlook use as well as access through other formats.
• Local handling: Read-only operation preserves the source PST, while the desktop product’s unlimited file-size claim makes it the more suitable route for large files.
• Browser recovery: The online service runs without local installation in Chrome, Firefox, Edge and Safari. Uploads are processed over a secure connection without a human touchpoint; files are deleted after 24 hours on Free or 48 hours on Premium. Those short download windows call for prompt retrieval.

Pricing

The online service has a clear single-file model. Free (online) costs nothing, requires no credit card, and covers one PST up to 500 MB, with the download available within 24 hours. Premium (online) costs $29.99, paid once, billed per file, and covers one PST over 500 MB and up to 5 GB, with download available within 48 hours. These are practical for an occasional file within the size cap, but neither is a fit for larger PSTs or repeated batches.

Desktop choices vary. Professional (desktop) is shown at $79, paid once, with the billing interval not stated; it includes unlimited PST size, unlimited files and local repair. The Professional plan is $99, paid once at the regular price and supports unlimited file size. Technician is $199, paid once and adds direct export to Microsoft 365 or Live Exchange. Toolkit is $499, paid once, also with unlimited file size. The available plan details do not identify what additional capabilities Toolkit includes, so the price alone does not establish a reason to choose it over a lower tier. Desktop trial users can scan and preview, but cannot save recovered data, so it does not replace a paid export route.

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 required to complete repair and save recovered data to a new PST. That makes desktop repair a poor fit for Mac users or anyone without licensed Outlook. The browser service avoids those local requirements and supports major browsers.

Who it's for

Choose Stellar when you need to recover and inspect PST mailbox contents, especially if the file is large, you need multiple export formats, or you want the original left untouched. Technician is the relevant edition when direct Microsoft 365 or Live Exchange export matters. The browser service suits a one-off PST within its 5 GB ceiling. Look elsewhere if you need desktop repair without Outlook installed, or if online download windows do not leave enough time to retrieve the file.

Pros and cons

• Pro: Recovery spans common mailbox items and deleted data, with preview and filters before export.
• Pro: Read-only repair avoids altering the original PST, and desktop handling supports unlimited file size.
• Pro: The online option skips installation and offers a free single-file route up to 500 MB.
• Con: Desktop repair requires supported 64-bit Windows, 8 GB of memory and licensed Outlook.
• Con: The desktop trial cannot save recovered data, so users must pay to complete an export.
• Con: Online service is limited to one PST per purchase and to 5 GB on Premium, with a 24- or 48-hour download window.

Alternatives

Email Recovery Software is the broader category to compare if you have not settled on a particular recovery tool.

• BitRecover Exchange Recovery is a Windows freemium alternative whose free plan saves 25 items per folder; consider it if that cap is sufficient for your Exchange recovery.
• Exchange EDB Recovery Tool has a free version with a 25-item-per-folder saving and migration limit; choose it if that allowance meets your needs.
• Recovery Toolbox for Outlook is an alternative with a Personal License at $39, paid once for noncommercial personal use.
• WholeClear Exchange Recovery offers a Personal plan at $299 a year for up to 20 systems, or a Professional lifetime license at $399, paid once.
• PST Walker has a Lite License at $32.95 a year, billed as a one-time payment, for personal use with viewing and export of up to 15 emails per folder.
• EdbMails EDB Recovery is a Windows option without a free plan; its Personal Edition is $99, paid once for lifetime licensing and unlimited mailbox recovery and export.
• EdbMails IMAP Migration Tool is a Windows alternative for IMAP/POP3 mailbox migration, including a 100-mailbox plan at $200, paid once.
• MailXaminer is another Windows alternative.

Verdict

Stellar Repair for Outlook is a strong fit for Outlook users who need selective, read-only PST recovery and varied export options, particularly when large files or direct Microsoft 365 and Live Exchange delivery are involved. Choose the online service for a single smaller PST when browser access is preferable. Look elsewhere if you cannot meet the desktop Windows and Outlook requirements, or if the online file-size and retrieval limits are too restrictive.
