we are looking to use the MS Graph API to create and send emails our issue relates to an odd behaviour we are experiencing when attaching large files.
All attachments under 3mb work as expected. Per MS documentation when attaching >3mb we should use the "Attach Large Files" API. Per that process we get a session and then chunk the upload, when we start the upload the API immediate terminates.
Has anyone been able to successfully attach a file > 3MB by breaking into smaller chunks and send an email. A similar plugin MS Graph Utilities uploads something larger files by breaking into chunks into One Drive/SharePoint but is there something similar which attaches it to an email?

Appreciate this is a 2 year old post, but if you can share how you sent emails with attachments, and what I'm doing wrong here, I'd really appreciate it!
