OST File Viewer

Preview OST Files in Bulk

Use the free OST File Viewer tool to effortlessly check and explore various OST files, including their contents and mailbox items. This information covers various data like emails, calendars, contacts, notes, and journals. This tool also generates a detailed report for a thorough analysis of the OST file. As a result, it makes it simple for you to view and read the information.

View OST Files Without Attachments

If you want to move OST emails without including their attachments, our tool has another feature called 'Migrate or Backup Emails without Attachment.' This helpful function lets you leave attachment files from your OST emails while moving them. By using this feature, you can save storage space while smoothly changing them without bringing along the attachments.

Open and Save OST Files into Multiple Formats

After carefully scanning your OST files and restoring them to their original state, you can convert them into several formats. This software allows users to save their OST files into PST, PDF, MBOX, EML, EMLX, MSG, CSV, HTML, and DOC. Moreover, this wizard maintains data integrity and bulk conversion, so you don’t need to worry about data loss.

Remove Duplicates Mails

When you use this OST File Viewer, it's smart enough to automatically find and remove duplicate emails during conversion. It removes duplicate emails on the basis of To, From, Subject, and Body. In short, only the actual, original version of each email gets moved, and any extra copies are smoothly removed. Plus, it only converts the first email into an OST inbox, leaving out any unnecessary duplicates.

Split Resultant PST Files

When people using Outlook have big OST files that need to turn into PST, it can be problematic. To help with this, the OST OST Viewer takes care of user problems. The tool has a unique feature called Split PST, which breaks the converted PST files into smaller parts, solving the issue.

Choose Mails Based on Keywords

This tool comes with special filters to make converting emails even more convenient. You can keep specific emails by using certain words or keywords in the process. You have two options to choose from - filters and extra filters. Under the filter section, you can search keywords on the basis of To, From, and Subject. In extra filters, you have a choice to pick keywords based on case sensitive and whole word.

Filtering Emails Using Date Filter

When your OST files have emails or data you don't need, our OST File Reader has a Mail filter option to help you exclude them easily. This feature lets you free up valuable storage space and ensures that only the essential OST files are saved after conversion. You can easily specify the date range—Start Date & End Date—and the tool will take care of it, keeping only the exact data you want.

Custom Folder Name

With the help of this OST File Opener utility, you have the freedom to make folders with names you like. Moreover, this feature helps you to find out the desired emails faster. Plus, you can save your emails with your name, using a mix of the 'To,' 'From,' 'Subject,' and 'Date' details.
