Opening a PST file in Outlook allows you to access archived emails and folders from a previous setup. If you’re wondering how to import pst file in outlook, this guide walks you through every step clearly and quickly. Whether you’re switching computers, restoring backups, or merging old data, the process is straightforward once you know the right menu options.
PST files are Outlook’s native data format for storing emails, contacts, calendar items, and tasks. Importing them is essential when you need to recover old messages or transfer your entire mailbox. Below, you’ll find a complete, step-by-step breakdown for Outlook 2016, 2019, 2021, and Microsoft 365.
What Is A PST File And Why Import It?
A PST file (Personal Storage Table) is a data file used by Microsoft Outlook to store copies of messages, calendar events, and other items locally on your computer. When you archive emails or export your mailbox, Outlook creates a PST file.
Importing a PST file is useful in several scenarios:
- You upgraded to a new computer and need to restore your old emails.
- You have an archived PST from a previous job or personal account.
- You want to merge data from another Outlook profile.
- You are recovering from a system crash or hard drive failure.
Understanding how to import pst file in outlook saves you time and prevents data loss. The process works similarly across most modern Outlook versions.
How To Import Pst File In Outlook
Follow these numbered steps to import your PST file into Outlook. The instructions are for Outlook 2016, 2019, 2021, and Microsoft 365. If you use Outlook 2013 or earlier, the steps are almost identical.
Step 1: Open Outlook And Locate The Import/Export Wizard
First, launch Outlook on your computer. Click on the File tab in the top-left corner of the ribbon menu. This opens the backstage view.
From the left sidebar, select Open & Export. Then click Import/Export. This launches the Import and Export Wizard, which is the main tool for bringing PST files into Outlook.
Step 2: Choose The Import Option
In the wizard window, you’ll see several options. Select Import from another program or file and click Next.
On the next screen, choose Outlook Data File (.pst) from the list. Then click Next again.
Step 3: Browse And Select Your PST File
Click the Browse button and navigate to the location of your PST file. It could be on your desktop, in a backup folder, or on an external drive. Select the file and click Open.
You have three options here:
- Replace duplicates with items imported – This overwrites existing items with the same data from the PST.
- Allow duplicates to be created – This keeps both the existing and imported items, even if they are identical.
- Do not import duplicates – This skips any items that already exist in your Outlook.
Choose the option that best fits your needs. Most users select Allow duplicates to be created to avoid losing anything, then clean up later.
Step 4: Select The Folder To Import From
After selecting the file, you’ll see a tree view of folders inside the PST. You can choose to import the entire PST file or just specific folders like Inbox, Sent Items, or Calendar.
Check the box that says Include subfolders if you want to import everything inside the selected folder. Also, make sure to select Import items into the same folder in and choose your current Outlook profile from the dropdown.
Click Finish to start the import. Depending on the size of your PST file, this may take a few seconds to several minutes.
Step 5: Verify The Imported Data
Once the import completes, you’ll see a new folder group in Outlook’s navigation pane, usually named after your PST file or “Imported Folder.” Expand it to find your emails, contacts, and other items.
If you imported into an existing folder, check that folder directly. You can now access all your archived data right alongside your current mailbox.
Alternative Method: Drag And Drop PST Files
Some users prefer a quicker method. If you have Outlook open, you can simply drag a PST file from your File Explorer directly into the Outlook navigation pane. Outlook will automatically mount it as a new data file.
This method does not technically “import” the data into your main mailbox, but it gives you full access to all items inside the PST. You can then copy or move emails between folders as needed.
To use this method:
- Open File Explorer and locate your PST file.
- Drag the file onto the Outlook icon in your taskbar or directly into the folder list on the left side of Outlook.
- Release the mouse button. Outlook will add the PST as a new data file.
This approach is faster but less organized if you plan to merge the data permanently.
Common Issues When Importing PST Files
Sometimes the import process does not go smoothly. Here are typical problems and how to fix them.
PST File Is Password Protected
If your PST file was created with a password, Outlook will prompt you for it during import. Make sure you remember the password. If you forgot it, recovery is difficult, but some third-party tools may help.
File Is Corrupted Or Too Large
A corrupted PST file may cause Outlook to crash or show errors. Try using the built-in Inbox Repair Tool (Scanpst.exe) located in your Outlook installation folder. Run the tool on the PST file before attempting to import again.
Large PST files (over 50 GB) can also cause issues. Consider splitting the file into smaller parts using Outlook’s export feature, then import each part separately.
Outlook Version Mismatch
PST files from older Outlook versions (like 2003) may not import directly into newer versions. You might need to open the PST in an intermediate version first, then export it again. Alternatively, use a third-party converter tool.
How To Import PST In Outlook For Mac
Outlook for Mac handles PST files differently. The desktop version for Mac does not have a built-in import wizard for PST files. However, you can use a workaround.
First, move the PST file to a Windows computer with Outlook installed. Import it there using the steps above. Then export the data as an OLM file (Outlook for Mac format). Finally, transfer the OLM file to your Mac and import it using Outlook for Mac’s Import option under the File menu.
If you don’t have access to a Windows machine, consider using a third-party PST to OLM converter. These tools are available online but vary in reliability.
Best Practices For Managing PST Files
To avoid headaches later, follow these tips:
- Always keep a backup of your PST file in a separate location, like an external drive or cloud storage.
- Use Outlook’s built-in archive feature regularly to keep your main mailbox small and fast.
- Name your PST files clearly, including the date and source (e.g., “Archive_2023_Work.pst”).
- Close Outlook before moving or copying PST files to prevent corruption.
Frequently Asked Questions
Can I import a PST file without Outlook installed?
No, you need Outlook to import a PST file. However, you can view the contents using third-party PST viewers, but full import requires Outlook.
What if my PST file is too large to import?
Outlook has a file size limit, usually 50 GB for newer versions. If your PST exceeds this, use the Inbox Repair Tool to compress it, or split it using Outlook’s export feature.
Will importing a PST file delete my existing emails?
No, importing adds data to your existing mailbox. It does not remove anything unless you choose the “Replace duplicates” option, which overwrites matching items.
How do I find my PST file on my computer?
By default, Outlook saves PST files in C:\Users\[YourUsername]\Documents\Outlook Files. You can also search for *.pst in File Explorer.
Can I import a PST file from one Outlook account to another?
Yes, you can import a PST file from any Outlook account into any other Outlook profile. The data will appear as a separate folder group unless you manually move items.
