Promote Get MIME content of a message (preview)
Per the [versioning documentation](https://docs.microsoft.com/en-us/graph/versioning-and-support) I am making a request to promote the O365 Graph API capability to [get MIME content of a message](https://docs.microsoft.com/en-us/graph/outlook-get-mime-message) from beta to general availability.
This is a requirement for our application as we need to save the emaill in our system. This functionality is available in the [EWS API](https://docs.microsoft.com/en-us/exchange/client-developer/web-service-reference/message-ex15websvcsotherref) but we would like to use the Graph API.
Is there any sort of timeline that could be provided for when this might make it into general availability?
