What happened?

I tried to send more than 50 MB of attachments. According to the discussion below the endpoint allows a maximum of 4 MB.

Notes

Maybe use createUploadSession when the attachments exceed 4 MB? I also want to take a look in this and create a pull request for this, but I don’t know when.

There is a security risk in this, because Mail.ReadWrite permission is required and this allows the user to read all emails of all users.
