How to Fix Video Uploads Not Working in Microsoft Sway
Question details
The user needs to resolve an issue where Microsoft Sway suddenly refuses to accept video uploads regardless of file format, size, storage location, or web browser.
- Product
- Microsoft Sway
- Device & OS
- not provided
- Scenario
- Attempting to upload video files such as MP4 or MOV into a Microsoft Sway presentation.
- Observed behavior
- The video upload process fails or stops working entirely across multiple Sways, even when trying different files, browsers, and user accounts.
Ensure your internet connection is stable and verify that the video files are not corrupted by playing them on your local media player before attempting to upload.
Check Microsoft Service Health and Server Status
Since the issue affects multiple accounts and file formats, it is highly likely a temporary server-side problem with Microsoft Sway.
Cloud-based applications like Sway rely entirely on server uptime. If Microsoft's servers are experiencing an outage or undergoing maintenance, media uploads will fail universally.
If you have an admin account, log into the Microsoft 365 admin center and navigate to Health > Service health to check for any active advisories regarding Sway.
Visit the official Microsoft 365 Status account on X (formerly Twitter) or use third-party outage tracking websites to see if other users are reporting similar Sway upload issues.
Ask coworkers if they are experiencing the same issue to confirm whether it is a widespread organizational outage or a Microsoft server-side problem.
Test Alternative Browsers and Private Windows
Rule out browser cache issues or extension conflicts that might be blocking the video upload scripts.
Troubleshoot File Storage Locations and Account Types
Changing where the file is hosted before uploading, or testing with a different account, can bypass account-specific glitches.
Create Stunning Presentations with WPS Office
While Microsoft Sway handles web-based storytelling, WPS Presentation offers a powerful, lightweight, and free alternative for creating professional slides. Enjoy high compatibility with Microsoft formats and a seamless, offline-capable experience that doesn't rely entirely on cloud servers for inserting videos.
- 1. Download and Install: Get WPS Office from the official website and install it on your PC, Mac, or mobile device.
- 2. Open WPS Presentation: Launch the application and select Presentation. Choose a free professional template or start from a blank slide.
- 3. Insert Media Locally: Navigate to the Insert tab and click on Video to seamlessly embed local media files directly into your slides without encountering cloud upload errors.
Frequently Asked Questions
What video formats does Microsoft Sway support?
Microsoft Sway generally supports standard web video formats like MP4 and MOV. Ensure your video uses standard codecs like H.264 for the best upload compatibility and playback performance.
Why does my video upload keep pausing or timing out in Sway?
Upload timeouts are usually caused by network instability, overly large video file sizes, or a temporary outage on Microsoft's servers. Try compressing the video to a smaller size or uploading from a different, stable network connection.
Can I embed a video in Sway instead of uploading it?
Yes. If direct file uploads are failing, you can upload your video to a platform like YouTube, Vimeo, or SharePoint, and then use the "Embed" card in Sway to display the video using its embed code.
Does the account type affect video uploads in Sway?
Yes, occasionally an organization's Microsoft 365 tenant settings may restrict certain storage limits or file sharing permissions, which can interfere with media uploads. Testing the upload with a personal Microsoft account can help identify if this is a tenant policy issue.
