Graph API support for O365 email export/import in eml (binary) format
Requirement - Graph API support for O365 email export/import in eml (binary) format
EWS provides support to export and import emails in the said format, this is particularly useful when we require export of an email or any item with full fidelity that includes all meta-data and attachments.
While Graph API can provide us all the meta-data, but import of an eml file is not permitted. Looking forward for this feature, as this can be used to backup mails on my local machine and restore if it is lost for some reason.
This will also ensure, feature parity between EWS API and Graph API
Paul Colby commented
Just to clarify, the "full fidelity" format provided by EWS is not the same as the eml file format used by Outlook. It's actually based on (possibly identical to) the Fast Transfer stream format defined in [MS-OXCFXICS].pdf, but officially opaque in the EWS specification [MS-OXWSBTRF].pdf.
But yes, I definitely want this feature too. And agree that Graph API cannot claim feature parity with EWS without it.
