How to Convert OST to MSG Format Without Losing Data

Users of Microsoft Outlook frequently need to store individual emails separately for backups, legal documentation, or sharing particular communications with other users. Converting OST emails to MSG format becomes highly helpful in these situations. A single email with all of its information—subject, sender, recipient, date, and attachments—is stored in MSG files. But it's not as simple as it seems to convert OST to MSG, particularly if the OST file is large, orphaned, or not connected to the Exchange server.

This tutorial describes the OST and MSG file types, why users require OST to MSG conversion, how to do it manually, and when using a professional solution is the best way to prevent data loss.

Understanding OST and MSG File Formats

Outlook stores a local copy of mailbox data that is synchronized with an Exchange or IMAP server using OST (Offline Storage Table) files. Even when the Internet is down, users can still check emails thanks to these files. However, OST files are server-dependent and cannot be opened independently on a different system. However, individual Outlook emails are stored as MSG files. Each MSG file contains an email, its attachments, and its metadata. Email archiving, legal searches, and sharing individual messages without exporting the entire mailbox are all common uses of this format. Users sometimes struggle with this conversion because Outlook does not provide a direct option to export OST emails to MSG in bulk.

Why Users Need to Convert OST to MSG Format

Here are several examples of why you may want to convert OST emails into the MSG file format:

• Email preservation for compliance or legal-oriented reasons
• Email sharing with clients or co-workers
• Email archiving of important messages, as they will be maintained separately
• Retrieving email messages from an orphaned or otherwise inaccessible OST file
• Reducing the need to export an entire mailbox when exporting only certain messages is desired

It is critical that data integrity be preserved during conversion to the MSG format in all examples mentioned above.

Manual Method to Convert OST Emails to MSG Format

Outlook lets users save emails as MSG files, but it's a difficult process that works best for a limited number of emails.

Method: Use Outlook to Save OST Emails as MSG

Steps:

• Start Microsoft Outlook from your Desktop.
• Confirm that the OST file is accessible and linked to Microsoft Outlook.
• Open the Mailbox folder that contains the e-mail messages that you want to convert.
• Double-click on the e-mail message you want to convert to open it.
• From the top menu, select "File", then select "Save As".
• Under "Send using the Outlook Message Format", select "Unicode (*.msg)".
• Select the folder where you want the e-mail messages to be saved and click "Save".

Repeat these steps for each email you want to convert.

The Manual Method's Drawbacks

Although this method works, it has several drawbacks:

• Emails need to be saved individually.
• Not appropriate for large mailboxes
• Needs Outlook to be completely operational.
• Unable to manage corrupted or orphaned OST files
• Time-consuming and human error-prone

These restrictions make manual conversion unfeasible for individuals handling hundreds or thousands of emails.

Reliable Way to Convert OST to MSG Without Data Loss

Emails can quickly be extracted from OST files and converted to MSG format using this software, with attachments, headers, and folder structure remaining untouched. The software maintains both accuracy and data safety. It does this by accepting both connected and orphaned OST files for usage and allowing users to preview their emails before conversion.

Steps to Convert OST to MSG Using the Tool

1. Start the software that converts OST to MSG.
2. Choose the OST file from your system by browsing it.
3. To load all mailbox data, scan the file.

Conclusion

For many users of Outlook, converting OST emails to MSG format is often a practical need; however, doing so manually can be unreliable and take much longer than desired. Outlook does allow for the storage of single emails as MSG files, but when dealing with large mailboxes or when dealing with a large OST file, this solution doesn't work. Using a professional conversion process provides accurate results, saves time, and prevents data loss. As a result, users are able to safely and easily convert from OST to MSG for the purpose of improving email management based on mailbox size and accessibility.
