Hello AugLearn,
Thank you for reaching out to Microsoft Support!
It looks like the issue you're encountering is related to the size of the file you're trying to convert. The Microsoft Graph API has limitations when it comes to handling large files for conversion. It's an expected behavior if you are handling with large files.
Chunked Upload and Conversion: Instead of trying to convert the entire file at once, you can try uploading the file in smaller chunks and then converting each chunk separately. This approach might help in managing the file size limitation.
Hope this helps.
