Know How to Rename OST File – The Simplest Way
Need to rename OST file? Then here is the complete guide that you can follow. An Outlook data file called an OST (Offline Storage Table) file is used to save a synchronized copy of mailbox data locally. It enables users to work with contacts, calendars, emails, and other mailbox data even when Outlook is unavailable. Although renaming an OST file is not too difficult, it should be done properly. When an OST file is inaccessible or renamed, Outlook may build a new one. Therefore, before making any modifications, users should be aware of the procedure and any potential consequences.
What is the Need to Rename OST File?
- To identify an OST file associated with a particular Outlook account
- To troubleshoot Outlook synchronization problems
- To prevent Outlook from using an existing OST file
- To organize multiple Outlook data files
How to Rename OST File Manually?
The manual method involves locating the OST file through Outlook’s account settings and then renaming it through Windows File Explorer.
Step 1: Close Microsoft Outlook
First, save any ongoing work and close Outlook.
Wait a few moments to ensure that Outlook has completely exited. If necessary, open Task Manager and check that no Outlook process is still running.
Step 2: Find the OST File Location
- The easiest way to identify the relevant OST file is through Outlook.
- Open Outlook and navigate to the account or data-file settings.
- You can also commonly find OST files under the user’s local Microsoft Outlook data directory. The precise location can vary depending on the Windows and Outlook configuration.
- The important thing is to identify the correct .ost file associated with your Outlook account.
Step 3: Open the File Location
- Once you have identified the OST file, open its location in Windows File Explorer.
- Before changing anything, check the file name and extension carefully. Make sure that you are working with the intended OST file rather than another Outlook data file.
Step 4: Rename the OST File
- Right-click the OST file and select Rename.
- Enter a new name while retaining the .ost extension. For example: Outlook_Old.ost
You can use a descriptive name if you have multiple OST files, such as: Account_Old.ost
Try an Alternative Technique to Rename OST File
Sometimes renaming an OST file is not enough. You may want to preserve the contents of the OST file, access its data independently, or move mailbox information into a more portable Outlook format. In that case opt for CubexSoft OST to PST converter. PST (Personal Storage Table) is an Outlook data-file format commonly used for storing and transferring mailbox information. This suitable solution can extract mailbox items from an accessible OST file and save them in PST format.
The software can be particularly helpful when:
- You need a backup of accessible OST data
- You want to migrate mailbox information
- You need to preserve emails before troubleshooting
- You want to access OST contents through a PST file
- Outlook is unable to use the original OST file normally
- You need to extract data from an old or orphaned OST file
Manual Renaming vs. Conversion Tool
These two approaches serve different purposes.
Manual OST renaming is mainly useful when you want to change the file name or troubleshoot Outlook by preventing it from immediately using an existing OST file.
OST to PST conversion, on the other hand, is focused on extracting and preserving mailbox data in PST format.
If your only goal is to rename the file, the manual method is usually the simplest option. If your goal is to preserve, migrate, or extract data from an OST file, conversion to PST may be more appropriate.

Wrap Up
As long as Outlook is closed and the right file is found, renaming an OST file is a simple Windows-based procedure. Finding the OST file, renaming it while keeping the.ost extension, and then restarting Outlook is the fundamental process. Users should keep in mind, but, that renaming an OST file does not equate to backing up its contents. After renaming an OST file, Outlook might produce a new one, therefore it’s not a good idea to expect that any unsynchronized data from the previous file would be present in the new one. So, the software solution might be taken into consideration as an extra choice if maintaining the mailbox data is the top priority. For backup, migration, or future use, it can assist in exporting accessible OST data into another PST format.
