Hello

I am trying to attach multiple large files (i.e. pdf, Docx) using Graph API by creating an upload session.

But Receiver received only the first attachment as I think while uploading bytes of the second file upload session is not being created.

I am using below link for reference:

Link : https://learn.microsoft.com/en-us/graph/api/attachment-createuploadsession?view=graph-rest-1.0&tabs=http

So if anyone can guide with this scenario will be appreciated.

And please let me know if you need any detail to guide me with this.

    I remember a handy code sample at the following thread; so you may want to give a try with that.
