What is Outlook Cache?

Outlook Cache is a feature of Outlook that stores email messages, calendar events, and other data locally on your computer. This cache helps Outlook to quickly access data without having to download it from the server again. It also helps Outlook to run faster and more smoothly. However, over time, the cache can become corrupt or outdated, leading to errors and slow performance. In order to avoid these issues, it’s important to periodically delete your Outlook Cache.

Understand the Outlook Cache

Outlook Cache is stored in a hidden folder called the “OST” (Offline Storage Table). This folder stores a copy of all the messages, contacts, and other data from your mail account. It also stores a copy of your calendar, tasks, and other items. The OST folder is automatically updated when you receive new emails or when you make changes to your calendar or other items in Outlook.

Clear the Outlook Cache

The easiest way to clear the Outlook Cache is to delete the OST folder. This can be done by pressing the Windows key+R to open the Run window, then typing in %appdata% and pressing Enter. This will open a folder called Roaming, which contains the OST folder. Right-click on the OST folder and select “Delete”. This will delete both the OST folder and its contents, effectively clearing the Outlook Cache.

How to Disable Outlook Cache

If you find that you need to disable the Outlook Cache, it can be done through the Control Panel. Start by opening the Control Panel, then click on “Mail” and select “Show Profiles”. Select your profile and click the “Properties” button. In the Properties window, select the “Advanced” tab and uncheck the box labeled “Use Cached Exchange Mode”. This will disable the Outlook Cache.

Using a Different Outlook Profile

If you need to use an Outlook profile with a different set of settings, you can do so by creating a new profile. To do this, open the Control Panel and click on “Mail”. Select the “Show Profiles” button and then click the “Add” button. Enter a name for the new profile, then select the “Finish” button. Select the new profile when you open Outlook and it will use a different set of settings.

Manually Delete Outlook Cache Files

In some cases, you may need to manually delete Outlook Cache files. To do this, open the Run window (Windows key+R) and type in %appdata%. Select the Roaming folder and then go to the Microsoft\Outlook folder. Delete any files with the .ost or .nst extension. Be sure to only delete these files and not any other files in the Outlook folder.

Check for Corrupt Outlook Cache

If you are experiencing errors with Outlook, it may be due to corrupt Outlook Cache. To check for corrupt Cache, open the Run window (Windows key+R) and type in scanpst.exe. This will open the Outlook Inbox Repair Tool, which can be used to scan your Outlook Cache for errors. If any errors are found, you can use the tool to fix them.

Backup Outlook Cache

It’s a good idea to periodically backup your Outlook Cache to avoid data loss. To do this, open the Run window (Windows key+R) and type in %appdata%. Select the Roaming folder and then go to the Microsoft\Outlook folder. Copy the OST file to a secure location, such as an external hard drive or a cloud storage service. This will allow you to restore your Outlook Cache in the event of a problem.

Use a Third-Party Tool

There are several third-party tools available that can be used to manage your Outlook Cache. These tools can be used to delete the cache, backup the cache, and check for corrupt files. They can also be used to optimize Outlook for better performance. It’s important to choose a reliable tool that is regularly updated to ensure compatibility with the latest version of Outlook.
