Stellar Repair for Outlook Software Review

Stellar Repair for Outlook is a renowned PST file repair software from Stellar® to repair corrupt or damaged Outlook PST files and recover your mailbox items, such as emails, calendars, contacts, notes, etc., with 100% integrity.

In this article, we will have a quick look at the Stellar Repair for Outlook software and share our review that might help you decide whether you should get this tool or skip it to fix your corrupt PST files.

Why You May Need Stellar repair for Outlook?

Before we share our review, let’s understand the need for third-party PST file repair software.

When you add an email account (POP3) in Microsoft Outlook, it creates a Personal Storage Table or PST to store all your mail items, such as emails, calendar, contacts, notes, etc., on your local system. PST is also a preferred file format when it comes to creating Outlook or Exchange mailbox backups.

You may also archive your old emails to PST file format for safekeeping and reducing the mailbox or PST file size. However, PST files are prone to corruption due to various reasons, such as,

  • Large-size or oversizing
  • Virus or malware intrusion
  • Incompatible or faulty add-ins
  • Abrupt system shutdown or crash
  • Force close or improper Outlook termination

And many more.

Although Microsoft provides a free ScanPST.exe or Inbox Repair Tool with MS Outlook to repair corrupt or inconsistent PST files, the tool has some limitations, as mentioned below, that may lead to failure and cause data loss.

  • ScanPST or Inbox Repair tool is recommended for PST files weighing 2GB or less. If you try repairing a large PST file, the tool may stop responding or get stuck during the repair. It may also crash and cause further damage to your PST file.
  • The tool can repair minor PST file corruption. However, if you try restoring severely corrupt PST files, the tool may fix them by removing or purging irrecoverable mail items that can lead to data loss.

However, with tools such as Stellar Repair for Outlook, you can repair large-sized, severely damaged, or password-protected Outlook PST files and restore all your mail items to a new PST file. You may also export the recovered mail items to an existing Outlook profile, Office 365, or Live Exchange Server account.

We recently got our hands on the Stellar Repair for Outlook software, and here is what we think of it.

Stellar Repair for Outlook- An Overview

Stellar Repair for Outlook reconstructs corrupt or severely damaged Outlook PST files and exports the mail items in a new PST file at your desired location. You can use the software to extract your emails, attachments, contacts, tasks, notes, journals, etc., from inaccessible PST files.

The software is also capable of repairing encrypted or password-protected PST files.

It also offers advanced features, such as the option to split a large PST file into smaller equivalent PSTs based on a date range or size. You may also choose to compact a large PST file to make it smaller, which helps protect PST files from corruption. In addition, it also saves your local drive storage and reduces mailbox size.

User Interface

Stellar Repair for Outlook features an easy-to-use and intuitive user interface inspired by the MS Outlook app. As a result, you will find the user interface quite familiar, making it easy for any user to repair and save mail items from corrupt PST files to PST and other multiple formats, such as EML, MSG, RTF, HTML, and PDF. You may also export a repaired PST file directly to your Office 365 account or Live Exchange mailbox.

It also allows you to export individual emails to PST and other supported formats.

You can fix a PST file up to 50GB in size.

The software auto-locates your default PST files associated with configured email profiles in your Outlook for repair. You may also choose PST files manually for repair or use the ‘Find’ option to locate the PST files if you are unsure where PST files are stored on your system or external media.

The software parses corrupt or damaged PST files, and displays all mail items in a three-pane preview window with a tree-like structure, making it easier to locate important mail items and save them.

You can preview all mail items displaying email body text, contacts, hyperlinks, tasks, calendars, and journals.

It also recovers deleted mail items and highlights them in Red color.

In addition, you can also save this scan information or repaired PST file information in the DAT file, which helps you resume saving the recovered mail items later from where you left them, saving time when you need to deal with a large or severely damaged PST file.

You can install the software on Windows 11, 10, 8.1, 8, and 7. Also, it supports MS Outlook 2019, 2016, 2013, 2010, 2007, 2003, and five international languages—English, Italian, German, French, and Spanish.
