A Brief about Outlook OST Files

An OST file allows Outlook to work offline by storing a synchronized copy of your mailbox data from the Exchange server. When you reconnect to the server, Outlook syncs any changes made while offline. However, OST files are tied to a specific Outlook profile and Exchange account, so they cannot be directly imported into a new profile or account without first converting or modifying them.

Steps Before You Attach Outlook OST Data File to New Profile

Before you can attach an OST file to a new Outlook profile, there are a few preliminary steps to ensure a smooth transition.

Step 1: Backup Your OST File

• Locate the OST File: By default, OST files are located in `C:\Users\[Your Username]\AppData\Local\Microsoft\Outlook\`. You can access this location by navigating to the folder or by using the search function in Windows.
• Copy the OST File: Copy the OST file to a safe location, such as an external drive or a different folder on your computer, to avoid data loss during the process.

Step 2: Create a New Outlook Profile

After you successfully locate and create a backup of your OST file it is now time to create a new Outlook profile. This can be done by following the steps mentioned below

1. Open Control Panel: Go to the Control Panel on your computer.
2. Select Mail: Find and select the “Mail” option (it might be labeled “Mail (Microsoft Outlook)” depending on your version).
3. Manage Profiles: Click on “Show Profiles” and then select “Add” to create a new profile.
4. Configure the New Profile: Follow the prompts to configure the new profile with your email account details. Make sure to set it as the default profile if you wish.

Steps to Attach Outlook OST Data File to New Profile

After extensive research, we found that there are no reliable methods to directly attach an OST file to a new profile. Therefore, we have divided this process into two steps. First, you need to convert your OST file to PST format, which can be done either manually or with an automated tool. Once the conversion is complete, you can use Outlook’s built-in feature to add the PST file to your new profile.

Step 1: Manually Change Outlook OST to PST

There are two ways to save OST files as PST. The former is a manual way and the latter is the automated way. Let’s explore both these methods in depth.

• Use Outlook’s Export Feature: If you can access the original profile with the OST file, you can open Outlook and export the data to a PST file.
• Open Outlook: Launch the Outlook application with the original profile.
• Go to File > Open & Export > Import/Export: Select “Export to a file” and click “Next.”
• Choose PST Format: Select “Outlook Data File (.pst)” and click “Next.”
• Select Data to Export: Choose the folders you want to export (e.g., Inbox, Sent Items) and click “Next.”
• Save PST File: Choose a location to save the PST file and click “Finish.” You may set a password for the PST file if desired.

Step 2: Professional Way to Convert OST to PST

The manual method is efficient but technical, and there are many cases of data loss or corruption. Therefore, when handling your OST files, it’s essential to choose the best tools available, such as the Regain OST to PST Converter.
