To import an old Outlook PST file into the new Outlook Mail, you can use the manual method provided by Microsoft. Follow these steps:
- Open the new Outlook and go to File > Open & Export > Import/Export.
- Choose "Import from another program or file" and click Next.
- Select "Outlook Data File (.pst)", then click Next.
- Browse and select the old PST file you want to import.
- Choose whether to allow duplicates or replace them, then click Next.
- Select the mailbox or folder to import and click Finish.
Challenges of the Manual Method
- Data Loss or Corruption: If the PST file is large or damaged, there’s a risk of data loss.
- Folder Structure Issues: The manual method may not always preserve folder hierarchy.
- Time-Consuming: Large PST files take a long time to import manually.
- Compatibility Errors: Older PST files might not be fully compatible with the latest Outlook versions.
