Resetting the SPO file handler cache

File handlers are cached in two ways: locally in the browser, and on the server. These caches have a timeout of 24 hours, meaning it can take up to 48 hours for updates to a file handler manifest to appear for users. Nevertheless, you can follow the instructions below to expedite the process.

To reset the cache:

1. Open the browser window and navigate to OneDrive. Submit the request below to refresh the server-side cache for OneDrive:

https://{tenant}-my.sharepoint.com/_api/v2.0/drive/apps?ForceRefresh=1

2. Submit the request below to refresh the server-side cache for SharePoint as Administrator:

https://{tenant}.sharepoint.com/_api/v2.0/drive/apps?adminForceRefresh=1

3. Clear the browser’s local data.

To clear the session cache for a specific application in Chrome, follow these steps:

1. Open Chrome and click the three dots in the upper-right corner of the window. Click More Tools and then Developer Tools. Alternatively, you can press Control-Shift-I (on Windows/Linux) or Command-Option-I (on Mac) on your keyboard.
2. In the Developer tools panel, click the Application tab.
3. In the left-hand panel, under Storage, expand Local Storage. Find your SharePoint site, right-click, and choose Clear to remove the stored data.
4. Under Storage, expand Session Storage. Find your SharePoint site, right-click, and choose Clear to remove the stored data.
