Fix PowerPoint in OneDrive Stuck on 'Please Wait' Loading Screen
Question details
Users are unable to open PowerPoint presentations stored in OneDrive or SharePoint because the file gets stuck on an infinite loading screen.

- Product
- Microsoft PowerPoint, OneDrive, SharePoint
- Device & OS
- Windows / Chromium-based browsers
- Scenario
- Opening a PowerPoint presentation via OneDrive or SharePoint on the web.
- Observed behavior
- The presentation fails to open and displays a continuous message saying 'Please wait... We are still loading the presentation.'
Verify whether this issue happens with all PowerPoint files or just a specific one, and ensure your web browser is up to date.
Allow Third-Party Cookies for Microsoft Domains
Adding essential Microsoft and Office domains to your browser's third-party cookie exception list often resolves the loading error in Chrome and Edge.
Chromium-based browsers like Google Chrome and Microsoft Edge sometimes block the cookies required by Office for the Web to authenticate and load presentations properly. Allowing these specific domains restores access.
In Google Chrome, click the three-dot menu in the top-right corner and select 'Settings'.
Go to 'Privacy and security' on the left sidebar, then click on 'Third-party cookies' or 'Site Settings'.
Under the section 'Allowed to use third-party cookies', click the 'Add' button.
Add the following domains one by one: `cac-powerpoint.officeapps.live.com`, `webshell.suite.office.com`, and `oauth.online.office.com`.
Close your browser completely and reopen it. Log back into OneDrive and try opening the PowerPoint presentation again.
Open the File Using the Desktop Application
Bypassing the web browser and opening the presentation directly from the desktop application avoids browser-based loading errors altogether.
Try WPS Office for Seamless Presentation Management
If Microsoft PowerPoint and OneDrive continue to experience web syncing or loading issues, WPS Office offers a free, lightweight, and highly compatible alternative. Easily open, edit, and save your PPT and PPTX files directly on your desktop without relying on browser-based cloud services.
- 1. Download WPS Office: Get the free installer from the official WPS Office website and complete the installation.
- 2. Open WPS Presentation: Launch the WPS Presentation module from the main dashboard.
- 3. Load your File: Click 'Open' and navigate to your local OneDrive folder to instantly access your presentations.

Frequently Asked Questions
Why is PowerPoint for the web stuck on 'Please wait'?
This problem is typically caused by strict privacy settings in Chromium-based browsers like Chrome or Edge. When the browser blocks third-party cookies from essential Microsoft domains, the authentication process fails, leaving the presentation stuck in a loading state.
Does this loading issue affect all web browsers?
No, users generally report this infinite loading screen only in Chromium-based browsers (such as Chrome and Edge) running on certain Windows versions (like Windows 21H2 and earlier). Browsers like Firefox are typically unaffected by this specific glitch.
How can I tell if the PowerPoint file itself is corrupted?
To test for file corruption, try opening a different PowerPoint presentation from your OneDrive. If other files open quickly and only one remains stuck, that specific file might be corrupted or excessively large. If all files fail to load, the issue is related to your browser settings.
Can I access my OneDrive presentation without using a web browser?
Yes. You can open your presentation directly using the desktop version of PowerPoint, or a compatible alternative like WPS Office, by going to File > Open and navigating to the local OneDrive sync folder on your computer.
