Following scenario: I have a mail with attachements (pdf, csv) files. I read the messages attachments with graph api /attachements and messageid ! I copied the contenByte value to clipboard and start a new post request with sendmail with attachment. I copied my clipboard to this new post request and want to see, if i can send a mail with attachment. The mail is sent, but the pdf attachment is broken after that. The csv attachment is working fine. What is wrong here ?

                      "message": {
                        "subject": "Hallo Welt",
                        "body": {
                          "contentType": "html",

    Hello dashandwerk.net (Frank Lehmann),

    Thanks for posting!

    As per my Investigation, it seems there is some issue with the value of pdf attachment content Byte which you are using to send mail with attachment i.e., content Byte value you are passing is incorrect. I am able to replicate the same scenario i.e., broken pdf when I am passing incorrect content Byte value.

    I would suggest you compare both (working and non-working content byte values) the content byte values.

    Hope this helps.
