It is the file format created by Microsoft Outlook to store a copy of your mailbox data, including emails, contacts, and calendar items. Over time, these files can grow large and take up considerable space. If you are running out of space on your current Exchange Server and want to move your OST file to another location, this blog will guide you.

So, let’s get started without further delay!

Why user move their OST file to another location?

Users may move their OST (Outlook Offline Storage Table) files to another location for various reasons. Here are some of the most common reasons:

  • Storage Space Issues: One of the primary reasons is running out of disk space on the current drive. Moving the OST file to another drive with more available space can help prevent performance issues and ensure that Outlook continues to function smoothly.
  • Data Migration: When switching to a new computer or email client, users may need to migrate their Outlook data, including OST files, to the new system. Moving the OST file to a different location is often a step in this migration process.
  • Performance Improvement: If the current drive where the OST file is located is slow or experiencing performance issues, users may move the OST file to a faster or more reliable storage medium to improve Outlook’s performance.
  • Data Security: Users may have concerns about the security of their email data and want to store their OST files in a more secure location, such as an encrypted external hard drive or a cloud storage service.
  • Accessibility: Some users may want to access their Outlook data from multiple devices or locations. Moving the OST file to a location accessible from different devices, such as a cloud storage service, can enable this.
  • Maintenance and Troubleshooting: Moving the OST file to another location can be a troubleshooting step if the existing OST file becomes corrupted or is causing issues with Outlook. Creating a new OST file in a different location may resolve these problems.

It’s important to note that when moving OST files, users should follow best practices and ensure that Outlook is properly configured to use the new file location to avoid any data loss or synchronization issues.

This method involves modifying the Windows Registry, so proceed with caution:

  • Close Outlook if it’s open.
  • Press Windows + R to open the Run dialog box.
  • Type “regedit” and press Enter to open the Windows Registry Editor. Add a New ForcePSTpath Registry Entry to change OST file location

If you’re not comfortable with the Registry Editor, consider seeking assistance from a knowledgeable IT professional.

Why Professionals Don’t Prefer Manual Methods?

The manual methods described to move an OST file to another location have their advantages, but they also have some potential drawbacks or limitations. Here are some of the potential loopholes or issues you may encounter when using these methods:

  • Data Redownload: In Method 1 (creating a new profile) and Method 2 (turning off Cached Exchange), Outlook may need to redownload your mailbox data, which can take time, especially if you have a large mailbox. This can also consume network bandwidth.
  • Complexity: Modifying the Windows Registry, as described in Method 3 (adding a ForcePSTPath Registry entry), can be complex and carries some risk. Making incorrect changes to the Registry can cause system instability or data loss if not done correctly.
  • Data Loss: If you’re not careful during the manual process, there’s a risk of losing data or email synchronization issues. This is particularly true if you don’t back up your OST file before making changes.
  • Incomplete OST Move: These methods primarily address changing the location of the OST file but do not necessarily “move” it as you would with a regular file. This means that in some cases, you may still need to manually copy the OST file to the new location and remove the old one, potentially leading to data fragmentation or other issues.

To minimize the potential issues and loopholes, always perform these operations with caution, create backups, and consider using automated tool. Additionally, keep your Outlook and Windows software up to date to benefit from any improvements or changes in handling OST files.
