Greetings!
In our project we started to use GRAPH API v.1.0 introduced some time ago and we wanted our users to be able to download *.eml file. For that we found that this is called MIME stream on MS side.
Long story short:
we use TypeScript (TS) and Graph Client library (@microsoft/microsoft-graph-client@^2.2.1);
We use request
await graphClient.api(/me/messages/${msgID}/$value).getStream()
The problem we started to notice is that 15MB email (with some attachments of 3-5MB) takes approximately 30sec to download whereas if email is downloaded via Outlook OWA (trhee dots on email > download) it takes few seconds.
Is there a way to increase the download speed using GRAPH api?
