How Do I Back Up PST Files?

Backing up PST files is one of the most direct and effective ways to protect your Outlook data. Here is how to do it step by step:

🛠️ Method 1: Export from Within Outlook

With this method you can export specific folders or the whole mailbox to a .pst file:

1. Open Outlook.

2. File > Open & Export > Import/Export: click this option.

3. “Export to a file”, then go on to “Outlook Data File (.pst)”.

4. Select the folders you want to back up (for example the Inbox).

5. Choose the destination and file name.

6. You can optionally add a password.

7. Click “Finish” to complete the process.

Outlook then exports the selected folders to a .pst file, which you can keep wherever you like.

📂 Method 2: Copy the PST File Manually

If you already have a PST file, you can back it up by copying it directly from the file system:

1. Close Outlook.

2. Go to the file location: C:\Users\<UserName>\Documents\Outlook Files

3. Select the relevant .pst file and copy it with Ctrl + C.

4. Paste it to an external disk, a cloud folder or another safe location with Ctrl + V.

Because Outlook is not running, this method keeps the file intact and gives you a safe backup.

🔐 Security Tips

• It is recommended to keep your backup files in an encrypted folder.

• If you use an external disk or cloud backup, enable two-factor authentication.

• Back up regularly and check file sizes (large PST files can affect Outlook performance).
