Additionally, a tool for converting OST files to PST that preserves the integrity of the mail items is going to be covered. This program can extract mail items from inconsistent, orphaned, or unreadable OST files. MS Outlook uses an Outlook data file known as an Offline Storage Table, or OST (also known as an Offline Folder file), to store your emails, attachments, notes, contacts, and other mail items. All of your contacts, emails, and other mail items are accessible to you through the OST file even if you are not online. The Procedure for Adding an OST File to a Fresh Profile Step1: Get Your System Ready Setting up your system is the first step. Once you have saved all of your work, close any open apps. In the process of attaching the OST, this will help avoid any disputes or data loss. Additionally, make an OST file backup. Having a backup is always a smart idea, even though attaching the OST file to a new profile is a safe operation. Your ability to view the emails in the OST file will be restored with its assistance. Depending on the Outlook and Windows versions, the OST file's default location changes. Still, the following place is typically where you may find the OST file: C:/Users/Your_Username/Local/AppData/Microsoft/Outlook Take a Look at Code Step 2: In Outlook, Create a New Profile • Shut down Outlook and launch the Control Panel. • Go to Mail (32-bit) under User Accounts. • In the Mail Setup window, click Show Profiles. • After selecting Add, choose a name for your new profile.

This empty profile will have the OST file attached to it. • Next, return to the Mail Setup window. By choosing the profile and selecting Remove, you can get rid of the previous one. • Click Yes to confirm when the prompt displays. Step 3: Join the new profile with the OST file. • Go into Outlook. An email account sign-in prompt will appear. (4)Log in to your newly established profile by providing your email credentials. All of the email items from your previous, inconsistent, or unreadable OST file will be downloaded to a new OST file that Microsoft Outlook creates and attaches to your updated profile. • Outlook will synchronize and download all mail items to your OST file after generating and adding the OST file to the new profile. Step 4: Examine the Information in the OST File Associated with the New Profile. Check your mail items after the OST file has been attached to the new profile. • If there are multiple profiles, open Outlook and select a different one. • Verify that all of the information in your mailbox—including contacts, calendars, and emails—is available and displays as it should. You have successfully attached an OST file to a new profile if everything appears to be in order.
