Cigati OST to PST Converter

Free Download Cigati OST to PST Converter for Windows PC. It is a professional mailbox conversion solution designed to convert OST data into PST and multiple other formats while keeping important email information protected.

Overview of Cigati OST to PST Converter

It is designed for businesses, professionals, and individual users who need a reliable way to move Outlook OST mailbox data. It can handle single and multiple files, making it suitable for small tasks and larger enterprise-level migrations. The software focuses on maintaining data accuracy while giving users greater control over the conversion process.

The tool can process emails, contacts, calendars, attachments, and other mailbox information while preserving the original structure. It also provides a preview feature, so users can examine mailbox content before starting the actual conversion. This makes the entire process easier to understand and helps avoid unnecessary data migration.

Convert OST Files to Multiple Formats

The software goes beyond basic OST to PST conversion by supporting several useful output formats. Users can export mailbox information into PST, MBOX, EML, EMLX, MSG, and other supported file types. This flexibility makes it easier to use converted data with different email applications and environments.

Document-based export options are also available. You can save mailbox content in formats such as PDF, DOC, DOCX, DOCM, HTML, and MHTML. These choices are useful when emails need to be archived, shared, viewed as documents, or stored outside a traditional email client.

Maintain Complete Data Integrity

Keeping mailbox information accurate is important during any email migration. The tool preserves the original folder hierarchy, metadata, email properties, attachments, and other important elements while processing OST files.

This means users don't have to reorganize everything after conversion. Folder relationships and message information remain organized, helping the converted mailbox look familiar and reducing the amount of manual work required afterward.

Bulk OST File Conversion

Processing files individually can become frustrating when hundreds of mailboxes are involved. The software supports bulk conversion, allowing users to work with multiple OST files instead of repeating the same process for every mailbox.

This feature is especially helpful for enterprise environments, growing startups, and SMBs handling large-scale email transitions. It reduces repetitive work and makes migration projects easier to manage. Large OST files can also be processed without a specified size limitation, making the tool practical for mailboxes containing years of communication.

Preview Mailbox Data Before Conversion

A built-in preview option allows users to inspect mailbox content before starting the final operation. You can examine available emails and other mailbox items first, which provides a clearer idea of what will be processed.

This is useful when working with large or unfamiliar OST files. Instead of converting data blindly, users can review the mailbox and make more informed decisions. It adds an extra layer of control to a process that can otherwise feel like moving boxes without knowing what's inside.

Remove Duplicate Emails

Duplicate messages can make an email archive unnecessarily large and difficult to manage. The tool includes a deduplication feature that identifies and removes repeated emails during processing.

It can recognize duplicates using properties such as To, From, Subject, Bcc, and Body. Removing repeated content helps create a cleaner mailbox archive and may also reduce unnecessary storage usage, especially when processing large collections accumulated over a long period.

Migration to Cloud Email Services

The software is not limited to saving mailbox data on a local computer. It also supports migration to cloud-based and webmail environments, giving organizations more options when changing their email infrastructure.

Users can migrate OST mailbox information to Office 365, Gmail, Google Workspace, Yahoo, IMAP, and other supported destinations. This is useful when moving from an Outlook-based setup to a cloud environment or consolidating email accounts onto a different platform.

Export Contacts and Calendar Data

Emails are only one part of an Outlook mailbox. Contacts and calendar entries may be equally valuable, especially in a business environment. The tool provides dedicated options for saving this information in commonly used formats.

You can save contacts as VCF files, making them easier to transfer between supported contact applications and devices. Calendar information can be exported into ICS format, providing a convenient way to preserve and move appointments, meetings, and other scheduled events.

Save Emails Without Attachments

Attachments can consume significant storage, especially in old business mailboxes containing documents, presentations, images, and other large files. The software lets you back up emails without including attachments.

This feature helps when the main goal is to preserve message content while reducing the size of the resulting backup. Users can create lighter archives instead of carrying unnecessary attachment data into every migration or backup.

Useful for Business Email Migration

The tool suits professional environments where reliability and organized data handling matter. IT teams can process multiple mailboxes, review content, remove duplicates, and select destinations based on their migration requirements.

Its combination of bulk processing, flexible export formats, cloud migration, and data protection makes complex transitions easier to manage. Instead of relying on several separate utilities, users can handle many common mailbox conversion and migration tasks in one application.

• Processor: Minimum 1 GHz Processor (2.4 GHz recommended)
