How to Import OST File into Outlook

[Ryancooper]

To Import OST file into Outlook manually, first, you'll need to convert the OST file to PST format, as Outlook doesn’t allow direct importing of OST files. Start by launching Outlook and navigating to File > Open & Export > Import/Export. Then select Export to a file, choose Outlook Data File (.pst), and select the folders to export. This process, however, is challenging as it relies on the original Outlook profile used to create the OST file, meaning if you no longer have access to that profile, you can’t open or export the OST.

For a simpler and more reliable solution, the Migrate Cloud Data OST to PST Converter Tool is highly recommended. This tool allows you to effortlessly convert OST to PST without needing the original profile, preserving email structure and attachments. Once converted, you can import the PST file into Outlook quickly and securely, saving time and reducing the risk of data loss.
