api sendmail limitations

Question

Hi, i am sending mails with api sendmail. When i attach one file the request is ok ! When attaching 2 files, or a bigger file (> 1MB) the request is broken. {"error":{"code":"ErrorInvalidParameter","message":"The value of the parameter 'Message' is empty."}} When copying the request to the graph explorer the request is OK ! Why is the request broken when doing a web api request and why is the request ok when using graph explrer ?

Hello @dashandwerk.net (Frank Lehmann),

Thanks for reaching out!

If you're attaching a file under 3 MB, you can add the file attachment to a message. If you're attaching a file between 3 MB and 150 MB to a message, you can create an upload session and iteratively upload ranges of the file to attach it.

Hope this helps.
