Convert OST to OBI

Understanding OST and OBI file formats

OST (Offline Storage Table) files are used by Microsoft Outlook to store a synchronized copy of mailbox information from an Exchange server, allowing users to access emails, calendar events, and other data offline. OBI files, on the other hand, are associated with Microsoft Outlook's RSS Feeds and are used to store subscription information for RSS feeds within Outlook.

Why convert OST to OBI?

Converting an OST file to an OBI file is not a standard or common conversion, as these formats serve different purposes within Outlook. However, if you need to extract RSS feed data from an OST file and import it as an OBI file, you may need to export the relevant data and re-import it as an RSS feed subscription.

How to convert OST to OBI

There is no direct conversion tool for OST to OBI because of their different functions. However, you can follow these steps to achieve a similar result:

1. Open Microsoft Outlook and load your OST file.
2. Locate the RSS Feeds folder in your mailbox.
3. Export the RSS feed items by selecting File → Open & Export → Import/Export.
4. Choose Export to a file and select Outlook Data File (.pst).
5. After exporting, you can import the RSS feeds into another Outlook profile, which will generate a new OBI file for the RSS subscriptions.

Best software for OST to OBI conversion

The best tool for handling this process is Microsoft Outlook itself, as it natively supports both OST and OBI files. For advanced extraction or conversion, third-party tools like Stellar Converter for OST or KDETools OST to PST Converter can help extract data from OST files, which you can then import into Outlook to create OBI files for RSS feeds.

Summary

While direct conversion from OST to OBI is not possible due to their different purposes, you can use Microsoft Outlook to export and re-import RSS feed data, effectively generating a new OBI file. For more complex needs, specialized OST conversion tools can assist in extracting the necessary data.
