How to Convert OST to PST with MS Outlook?

Converting an OST (Offline Storage Table) file to a PST (Personal Storage Table) file in MS Outlook is a common task for users who need to move data from their local Outlook profiles or migrate from Exchange servers. Here's how you can do it manually:

Method 1: Export to PST via Outlook (Best for Regular Users)

• Open Microsoft Outlook: Start Outlook with the profile linked to your OST file.
• Ensure that Outlook is connected to the internet, particularly if you're using Exchange, so that all your data is synced.
• Create a New PST File: Go to the File tab in Outlook.
• Select Account Settings > Account Settings.
• In the Account Settings window, click on the Data Files tab.
• Click on Add to create a new PST file. Choose a location and name for this file.
• Copy OST Data to PST: Go to the left panel of Outlook, and you'll see your OST data (e.g., Inbox, Sent Items, Calendar).
• Right-click on the folder you want to convert (such as Inbox), and click Copy Folder.
• Choose the newly created PST file as the destination and copy the data over.
• Repeat for Other Folders: Repeat the same process for other folders like Sent Items, Calendar, Contacts, etc.
• You can also manually drag and drop items (e.g., emails) from the OST folders to the PST folders.
• Close Outlook: After the data has been copied, close Outlook. Your OST data should now be in the PST format and can be accessed anytime.

Method 2: Using the "Archive" Feature in Outlook

• Open Microsoft Outlook: Open Outlook and ensure your OST file is connected.
• Enable AutoArchive: Go to File > Options > Advanced.
• Scroll down to AutoArchive Settings and make sure AutoArchive is enabled.
• Manually Archive to PST: Click on the File tab again.
• Select Tools and then Clean up old items or choose Archive.
• Choose Archive this folder and all subfolders and select the folder(s) you want to archive (e.g., Inbox, Calendar).
• Choose to archive items to a new PST file or an existing one.
• Finish and Exit Outlook: After the archive process completes, the items will be stored in the PST file you created.
• Close Outlook, and you’ll now have a PST file containing your data.
