Two methods exist to import PST files to Outlook: manually or professionally. For the manual method, open Outlook and navigate to File > Open & Export > Import/Export. Select Import from another program or file and choose Outlook Data File (.pst). Look for and select the PST file and specify the import location (i.e., the mailbox being used now or a new folder). Choose whether or not to import subfolders and handle duplicates. Click Finish to complete the process. This method has direct control over importing but requires careful selection of destination folders to avoid cluttering.

Manual PST imports are restricted, for example, file size restrictions (typically 20-50GB) due to Outlook performance problems. Very large PST files may result in crashing or corruption. Manual imports also do not allow for automatic scheduling or batch processing, so they are slow for multiple files.

Using the DRS Softech PST to Office 365 Migration Tool is the best way to import PST files into a fresh Outlook installation in Office 365. It simplifies the migration process, maintains data integrity, and offers a smooth transition without the risk of data loss or corruption. It provides a secure and automated personal use or enterprise-level migration solution for Outlook users. The tool eliminates time-consuming manual migration steps by directly importing PST files to Office 365 mailboxes.
