Here's a step-by-step guide to converting OST to PST using Microsoft Outlook's Import/Export Wizard:
Step 1: Open Microsoft Outlook on your computer.
Step 2: Create a new Outlook PST file (if you don't have one already) by going to "File" > "New" > "Outlook Data File" and selecting the PST format. Choose a location to save the PST file and provide a name for it.
Step 3: Go to the "File" tab in the Outlook menu.
Step 4: Select "Open & Export" and then click on "Import/Export" to open the Import and Export Wizard.
Step 5: In the Import and Export Wizard, select "Export to a file" and click "Next."
Step 6: Choose "Outlook Data File (.pst)" as the file type to export and click "Next."
Step 7: Select the OST file you want to convert by using the "Browse" button. You can also choose whether to include subfolders.
Step 8: Choose the destination folder in which you want to save the converted PST file. You can either select an existing folder or create a new one.
Step 9: If you want to exclude specific folders from the conversion, click on "Filter" and set the criteria according to your preferences. Otherwise, proceed without applying any filters.
Step 10: Check the box labeled "Replace duplicates with items exported" if you want to handle duplicate items during the conversion process. Click "Finish" to start the conversion.
Step 11: Outlook will prompt you to set a password for the PST file (optional). You can set a password or leave it blank, depending on your preference.
Step 12: Wait for the conversion process to complete. The time required may vary depending on the size of the OST file.
Once the conversion is finished, you will have a PST file containing the converted data from the OST file. You can import this PST file into Outlook to access your mailbox data.
Note: This method assumes that you have a connected Exchange account in Outlook and the OST file is in a healthy state. If your OST file is corrupt or inaccessible, you may need to use third-party OST to PST converter tools for recovery and conversion.
I would like to suggest Kernel for OST to PST Converter software. The software provides a comprehensive preview feature that allows you to preview the contents of the OST file before initiating the conversion. You can view emails, attachments, contacts, calendars, and other items to ensure the accuracy of the conversion.
