Troubleshoot File Upload Size Limits in Microsoft Copilot for Edge and Web
Question details
The user requires clarification on the file upload size limits for Microsoft Copilot for Web and Edge under Microsoft 365 E3 or E5 licenses.
- Product
- Microsoft Copilot
- Device & OS
- not provided
- Scenario
- Attempting to perform product demonstrations using Microsoft Copilot and needing reliable file upload capabilities.
- Observed behavior
- The file upload limit appears unclear and behaves inconsistently, making it difficult to conduct seamless product demonstrations.
Verify that your Microsoft 365 E3 or E5 subscription is active and ensure your web browser is updated to the latest version before testing uploads.
Consult Microsoft Q&A and Clear Browser Data
Since Copilot upload limits can vary by license and updates, posting to Microsoft experts ensures accurate information. Clearing your browser cache can resolve local inconsistencies.
Microsoft Copilot features and limitations frequently evolve. If documentation is unclear regarding specific E3 or E5 file upload limits, the official Microsoft Q&A forum is the best escalation path. Additionally, browser-based caching issues can sometimes falsely trigger upload limit errors.
Navigate to the Microsoft Q&A platform and post your specific limit question. Ensure you apply both the 'Microsoft Copilot' and 'Microsoft Edge' tags so the correct product experts see and address your query.
If the upload behavior is inconsistent, open your browser settings (in Edge, go to Settings > Privacy, search, and services), and clear your cached data and cookies to remove corrupted site data.
Open a different web browser, navigate to Copilot for Web, sign in with your E3/E5 account, and attempt the file upload again to rule out browser-specific limitations.
