Understanding PST Files and the New Outlook
Before you begin the import process, understand what a PST file is and how the New Outlook application handles data.
What is a PST File?
A PST (Personal Storage Table) file is a proprietary file format used by Microsoft Outlook to store copies of messages, calendar events, and other items within Microsoft 365 software. These files allow you to back up your Outlook mails or transfer Outlook data between computers or Outlook profiles.
New Outlook: Key Changes for Data Management
The New Outlook for Windows represents a significant redesign and a distinct version of Outlook. It offers a streamlined interface and enhanced performance. For data management, the New Outlook integrates more closely with cloud services. It handles PST files differently from its classic counterpart, primarily focusing on cloud-synced mailboxes. Direct, client-side PST imports function differently.
New Outlook Vs Classic Outlook
It is crucial to understand the distinction between New Outlook and Old Outlook regarding PST file handling. Outlook Classic directly supports importing and opening PST files for full integration into your profile. New Outlook, however, is primarily a cloud-centric application. It does not natively support direct PST import in the same way Classic Outlook does. Instead, you typically add an email account where your data (including PST content) might reside, or you use a specific import utility if available. This guide addresses the current methods available within the New Outlook experience.
Important Preparations Before Importing
Proper preparation prevents potential issues during the import process. Complete these steps before attempting any import.
A. Backup Your Existing Data
Always back up your existing Outlook data before making significant changes to prevent potential data loss. This ensures data recovery if an unforeseen issue occurs. You can back up your current Outlook profile or any important data files.
B. Ensure Outlook is Updated
Make sure your New Outlook application is updated to the latest version. Microsoft frequently releases updates that include bug fixes and feature enhancements, which can improve the import process.
C. Locate Your PST File
You must know the exact location of your PST file on your computer, typically created by Microsoft Office Outlook. Common locations include the Documents\Outlook Files folder or specific directories where you saved previous Outlook backups. Note the full path to your PST file.
Step-by-Step: Importing a PST File into New Outlook
The New Outlook environment handles PST files through a slightly different mechanism than Classic Outlook. Follow these methods carefully.
Method 1: Using the Import/Export Wizard (Recommended for Migrated Data)
This method is recommended if you are migrating from Classic Outlook (e.g., Outlook 2013) or have access to the Classic Outlook application. New Outlook does not have direct “Import PST” import options as Classic Outlook does. Instead, you generally import data into an account that New Outlook then accesses.
Part 1: Export From Outlook Classic
1. Open Classic Outlook: If you have Classic Outlook installed, open Outlook.
2. Access Import/Export: Go to File > Open & Export > Import/Export.

3. Choose “Export to a file”: Select this option and click Next.

4. Select “Outlook Data File (.pst)“: Choose this file type and click Next.

5. Select Folders to Transfer: Choose the data that you would like to transfer to New Outlook and click on Next.
6. Export Outlook data: Browse for a location, provide a name for your backup file, and then select Finish.
7. Allow Import to Complete: Outlook will import the data. This process may take time depending on the PST file size.
8. Verify in New Outlook: Once the import completes in Classic Outlook, open New Outlook. If the account you imported into, such as a Microsoft Exchange account, is synced with New Outlook, the imported data will appear.
Method 2: Opening a PST File Directly (For Viewing Only)
The New Outlook application does not directly “open” a PST file to integrate it into your folder list on the left side in the same way Classic Outlook does, especially for accounts configured with IMAP. For viewing PST content in New Outlook, you typically add an account to New Outlook that already contains the data, or you might need to use a temporary workaround.
Currently, New Outlook does not support directly opening a .pst file for display as a separate data file like Classic Outlook. Its design emphasizes cloud-synced accounts. If you need to view data from a PST, you generally need to:
- Import it into Classic Outlook first (as described in Method 1) and then access that account via New Outlook.
- Utilize a third-party PST viewer if you only need to view the contents without full integration.
This limitation is a key difference in data management between the two Outlook versions.
Troubleshooting Common Import Issues
- You may encounter issues during or after the import process. Here are solutions to common problems.
PST File is Corrupted
If your PST file is corrupted, the import will fail.
- Use Scanpst.exe: Microsoft provides an inbox repair tool called Scanpst.exe. Locate this utility (it’s usually in your Office installation directory) and run it against your PST file to repair any errors.
- Try Data Recovery Software: If Scanpst.exe fails, consider using specialized third-party PST data recovery software.
Import Process is Slow or Freezes
A large PST file can cause slow performance or freezes.
- Close Other Applications: Close all other unnecessary programs on your computer to free up system resources.
- Break Up Large PST Files: If possible, consider breaking a very large PST file into smaller ones using Classic Outlook’s archive features before importing.
- Ensure Sufficient Disk Space: Verify you have ample free disk space on your drive.
Note: In such cases it may help to use an Outlook transfer tool like Remo Outlook Backup & Migrate.
Missing Data After Import
If some data appears to be missing after the import.
- Check All Folders: Thoroughly check all folders, including subfolders, in your imported account. Sometimes data might be imported into a different folder than expected.
- Verify Import Steps: Review the import steps you followed to ensure no steps were missed or incorrectly executed.
- Search for Items: Use Outlook’s search function to look for specific missing items.
Frequently Asked Questions About PST Imports
No, you typically import one PST file at a time using the Classic Outlook Import/Export wizard. You must repeat the process for each individual PST file you wish to import.
Yes, when you import a PST file using Classic Outlook’s Import/Export wizard, the original folder structure within the PST file is preserved. The folders will appear as subfolders under the destination you choose.
The “Import/Export” option is found in Classic Outlook, not directly within the New Outlook application interface. If you are in New Outlook, you will not find this option. You must switch to or install Classic Outlook to perform the direct PST import.
