DISCUSSION

Users have reported that attempts to upload files larger than 2GB to SharePoint result in failure. This limitation affects both SharePoint Online (365) and On-Premises SharePoint (2016/2019) environments.

Root Cause

• The file size limitation is dictated by SharePoint’s server configurations and Microsoft’s platform boundaries.
• In Automate, all SharePoint operations rely on CSOM (Client-Side Object Model), which itself does not impose file size limits. However, SharePoint’s backend enforces these restrictions.
• The default maximum file size for uploads is 2GB in most configurations.

Details

• SharePoint On-Premises (2016/2019):
  See official Microsoft documentation for software boundaries and limits:
  https://learn.microsoft.com/en-us/sharepoint/install/software-boundaries-limits-2019
• SharePoint Online (365):
  For cloud environments, refer to:
  https://learn.microsoft.com/en-us/office365/servicedescriptions/sharepoint-online-service-description/sharepoint-online-limits
• These limits may vary depending on the SharePoint version, authorization type, and server setup configured by SharePoint administrators.

Workarounds and Alternatives

• Some third-party tools may use alternative SDKs or APIs that support chunked uploads, potentially bypassing the 2GB limit.
• Automate does not support partial/chunk uploads, so files must be within the allowed size limit.

Recommendations

• Before uploading, verify the file size and ensure it does not exceed the 2GB limit.
• For larger files, consider splitting them or using alternative storage solutions.
• Consult your SharePoint administrator for possible configuration changes or approved third-party tools.
