                                                                   .GetAsync();

it's throwing below error

Cannot write more bytes to the buffer than the configured maximum buffer size: 2147483647.

Could you please help me with this issue.

Hi @Babu P ,

Consider using Partial range downloads, Note that you must append the Range header to the actual @microsoft.graph.downloadUrl URL and not to the request for content.

Hope this helps.
