We are working on a security product for which we want to perform bulk ingestion of raw eml files from inbox of all employees in an organization.

I am new to Microsoft Graph and narrowed down between MS Graph Data Connect vs Graph API to do this job.

1. Am I correct in assuming ingestion of raw eml data with Graph Data Connect will not be feasible as it includes only datasets with fixed attributes. This dataset does not contain any attribute for raw eml download.
2. In this case, Graph API is the only option left, it allows downloading of MIME-Content from email – this seems to include all headers + body of the email. Is this the way to go for downloading eml data?
3. How feasible is ingesting large data using the MS graph API?

4. For organizations with an 365 subscription, this would be free of charge right? Apart from the standard rate limits.
