Prerequisites
Before you start, ensure you have:
- Microsoft Outlook installed on your computer.
- The OST file you want to add.
- Access to the email account associated with the OST file (for synchronization purposes).
What is an OST File in Outlook?
An OST (Offline Storage Table) file is a data file used by Microsoft Outlook to store a local copy of a user’s mailbox information. This file type is particularly useful in environments where users need to access their emails and other mailbox contents while not connected to the internet.
When a user is connected to their email server, the OST file synchronizes with the server, ensuring that any changes made while offline are updated once a connection is re-established.
This synchronization capability is essential for users who frequently work in environments with limited or intermittent internet access, such as during travel or in remote locations.
OST files facilitate seamless email management by storing not only email messages but also calendar events, contacts, tasks, and other mailbox items. This comprehensive storage allows users to access and manage their complete mailbox even when offline, ensuring productivity is not hampered by connectivity issues.
The OST file’s role in maintaining synchronization with the Exchange server or other email servers also means that users can work offline without worrying about data loss or inconsistency.
Moreover, OST files enhance the overall user experience by allowing for faster access to mailbox items. Since the data is stored locally on the user’s computer, retrieving and displaying emails, calendar entries, and other items can be quicker than accessing them directly from the server.
This local storage also provides a safeguard against server outages, ensuring that users can continue to access their important information even if the email server is temporarily unavailable.
An OST file is a crucial component of Microsoft Outlook’s functionality, enabling users to work offline, ensuring data synchronization, and enhancing access speed and reliability.
Its ability to store a comprehensive copy of the mailbox locally makes it an indispensable tool for maintaining productivity in a variety of working conditions.
Why Add OST File to Outlook?
Adding an Offline Storage Table (OST) file in Outlook provides several significant benefits that enhance the user experience and functionality of the email client.
Here are some key reasons why you might want to add an OST file in Outlook:
1: Offline Access with OST Files
One of the primary benefits of an OST file is the ability to access your emails, calendar entries, contacts, and other data offline. This is particularly useful if you are frequently on the move or in areas with limited or no internet connectivity.
You can read and compose emails, schedule appointments, and manage tasks without being connected to the internet. Once you reconnect, Outlook will automatically synchronize the changes with the server.
2: Enhanced Performance Using OST Files
Working with an OST file can improve Outlook’s performance. Since the data is stored locally on your device, accessing and managing your emails and other items is faster. This reduces the load on the server and enhances the overall responsiveness of the Outlook application.
3: Reliable Data Backup with OST Files
An OST file acts as a backup of your mailbox data. In case of server issues or data loss on the server side, you still have a local copy of your emails and other important information. This provides an added layer of security and peace of mind, knowing that your data is not solely dependent on the server’s health.
4: Seamless Synchronization with OST Files
OST files facilitate seamless synchronization between your local device and the mail server. Any changes made offline, such as composing emails, deleting items, or moving emails between folders, are synchronized with the server once an internet connection is re-established. This ensures that your mailbox remains consistent across all your devices.
5: Support for Cached Exchange Mode with OST Files
For users connected to Microsoft Exchange Server, enabling Cached Exchange Mode creates an OST file on your local machine. This mode allows you to work efficiently with a copy of your mailbox stored on your computer, while Outlook periodically synchronizes this copy with the server. Cached Exchange Mode is particularly beneficial for improving performance and reducing server dependency.
6: Increased Mobility with OST File Integration
Adding an OST file is advantageous for users who frequently switch between different network environments or devices. Since the OST file is stored locally, you can carry your work seamlessly across various locations and network conditions without worrying about connectivity issues.
7: Handling Large Mailboxes with OST Files
For users with large mailboxes, using an OST file helps manage the data more effectively. Since a local copy of the mailbox is maintained, you can quickly access large volumes of emails and attachments without constantly querying the server, which can be slow and inefficient.
Adding an OST file in Outlook provides a range of benefits including offline access, improved performance, data backup, seamless synchronization, support for Cached Exchange Mode, enhanced mobility, and efficient management of large mailboxes.
These advantages make OST files an essential component for users who rely on Outlook for their email communication and data management needs.
5 Steps to Add OST File to Outlook
Adding an OST file in Outlook can help you manage your email more effectively and ensure you have access to your emails even when you’re offline.
Here are five steps to guide you through the process.
Step 1: Backup Existing Outlook Data Before Adding OST File
Before making any changes to your Outlook setup, it is crucial to back up your existing data. This ensures that you have a copy of your important emails, contacts, calendar entries, and other data in case anything goes wrong during the process.
- Export to PST File: Open Outlook and go to File > Open & Export > Import/Export. Select Export to a file, choose Outlook Data File (.pst), and select the folders you want to back up. Save the file to a secure location. If you get an error while creating the file see how to fix “Couldn’t create the outlook data file” & Secure your data.
- Use Outlook’s Archive Feature: Navigate to File > Info > Tools > Clean up old items. Select Archive this folder and all subfolders, choose a date, and specify a location to save the archive file.
- Copy Important Files: Manually copy essential files like calendar entries and contacts to another location or external drive for extra safety.
Backing up ensures that even if the OST file setup encounters issues, your data remains intact and can be restored easily.
Step 2: Locate the OST File on Your System
Locating the OST file is the next step. The OST (Offline Storage Table) file is where Outlook stores a synchronized copy of your mailbox data.
- Default Locations: The default location for OST files on a Windows PC is usually in the C:\Users\ [Your Username] \AppData\Local\Microsoft\Outlook directory. You can access this folder by navigating through the File Explorer or entering the path in the Run dialog (Windows + R).
- Outlook Settings: Open Outlook, go to File > Account Settings > Account Settings. In the Data Files tab, you will see the path of the OST file associated with your email account.
- Hidden Files: Ensure that hidden files and folders are visible. In File Explorer, go to View > Options > Change folder and search options. In the View tab, select Show hidden files, folders, and drives.
Locating the OST file is essential for the next steps where you will configure Outlook to recognize and use this file.
Step 3: Configure Your Email Account in Outlook
Configuring your email account correctly is crucial for Outlook to work with the OST file.
- Open Outlook: Launch Outlook and navigate to File > Account Settings > Account Settings.
- Create a New Profile: In the Profiles tab, click Add to create a new profile. Enter a name for the profile and set up your email account. Ensure you choose the Manual setup or additional server types option for more control.
- Enter Email Settings: Input the necessary email account settings, such as the incoming and outgoing server details, username, and password. This information is typically provided by your email service provider.
Properly configuring your email account ensures that Outlook can communicate with your email server and sync data accurately. For a seamless email experience, consider using a reliable email hosting provider like ARZ Host.
Our secure and scalable email hosting solutions are designed to support effective email management and ensure your communication remains smooth and reliable.
Step 4: Set Up Outlook to Use the OST File
Once your email account is configured, you need to set up Outlook to use the OST file.
- Open Data File Settings: In Outlook, go to File > Account Settings > Account Settings. Select the newly created profile and click Change.
- More Settings: In the new window, click More Settings, then go to the Advanced tab.
- Offline Folder File Settings: Click Offline Folder File Settings, then Browse to locate and select the OST file you found earlier.
This step ensures that Outlook uses the correct OST file to store and retrieve your email data, enabling offline access.
Step 5: Synchronize Outlook with the Server Using OST File
The final step is to synchronize Outlook with your email server to ensure all your data is up-to-date.
- Open Outlook: Ensure you are connected to the internet and open Outlook with the new profile you created.
- Initiate Sync: Outlook should automatically begin syncing with the email server. You can monitor the sync progress in the status bar at the bottom of the Outlook window.
- Check Data: Once the sync is complete, check to make sure all your emails, contacts, and calendar entries are present and correct.
Synchronizing with the server ensures that all your latest emails and other data are available in Outlook and that any changes you make while offline are updated when you reconnect. To enhance this process and streamline your workflow, consider leveraging email automation tools to boost your business.
Following these steps carefully will help you add an OST file in Outlook efficiently, ensuring you have a robust email management system in place.

FAQs (Frequently Asked Questions)
1: What is an OST file, and why would I need to add it to Outlook?
An OST (Offline Storage Table) file is an offline folder file in Microsoft Outlook that stores a synchronized copy of mailbox data from the Exchange server. This allows users to access their emails, calendar entries, contacts, and other data even when they are not connected to the internet.
Adding an OST file to Outlook is crucial for users who need to work offline and synchronize their work with the server once they reconnect. It is particularly useful for people who frequently travel or work in areas with limited internet access.
By using an OST file, users can continue to work seamlessly and ensure that all their changes are updated on the server when they go online again.
2: How can I add an existing OST file to my Outlook profile?
To add an existing OST file to your Outlook profile, you need to follow several steps. First, ensure that Outlook is closed. Locate the OST file you want to add, which is typically found in the default location: C:\Users\YourUsername\AppData\Local\Microsoft\Outlook.
Copy this file to a safe location if needed. Open Control Panel, go to the Mail settings, and select “Show Profiles.” Choose the profile you want to add the OST file to, and click on “Properties.”
In the Mail Setup window, click on “Data Files,” then “Add,” and select “Outlook Data File (.pst).” Browse to the location of your OST file and add it. Note that Outlook will convert the OST file to a PST file as it cannot directly open an OST file created for another profile. Restart Outlook, and your data should now be accessible.
3: What should I do if Outlook cannot open the OST file?
If Outlook cannot open the OST file, it might be due to corruption or a synchronization issue with the Exchange server. Start by using the built-in Inbox Repair Tool (Scanpst.exe) to repair the file. Locate Scanpst.exe in the Outlook installation directory and run it.
Follow the prompts to select the problematic OST file and initiate the repair process. If this does not resolve the issue, consider using third-party OST to PST converter tools that can recover data from corrupted OST files and save it in a PST format, which can then be added to Outlook.
Additionally, ensure that your Outlook and Exchange server settings are correctly configured, and try recreating the OST file by deleting the old one and letting Outlook generate a new one during the next synchronization.
4: Can I add an OST file from a different profile or another user’s account?
No, you cannot directly add an OST file from a different profile or another user’s account to your Outlook profile. OST files are linked to the specific profile and account that created them and are encrypted for security reasons.
However, you can convert an OST file to a PST file using various third-party tools. Once converted to a PST file, you can add it to your Outlook profile using the “Open Outlook Data File” option under the “File” menu.
This way, you can access the data contained in the OST file, albeit in a different format.
5: Is it possible to import an OST file directly into Outlook without conversion?
No, it is not possible to import an OST file directly into Outlook without conversion. OST files are intended for offline use and synchronization with the Exchange server and cannot be imported directly like PST files.
To access the data in an OST file, you must either synchronize it with the Exchange server using the original profile or convert it to a PST file using a third-party OST to PST converter.
Once converted, the PST file can be imported into Outlook through the “Import/Export” wizard or opened directly within the application. This process ensures that all the emails, contacts, and other data from the OST file are accessible in your current Outlook profile.
