/me/{messages,events,contacts} are not store-wide
result collection class?
check https://developer.microsoft.com/en-us/graph/docs/concepts/query_parameters
efficient attachment streaming? using our own $value approach for now..
bulk copy/move/delete?
childFolders recursion/relative paths
Message.{isDraft, webLink, inferenceClassification}?
Event.{webLink, onlineMeetingUrl, uniqueBody, responseStatus, isCancelled}?
Attachment.{contentId, contentLocation}?
/me/{mailFolders,contactFolders,calendars} -> which folders exactly?
@odata.context: check exact structure?
ICS, filters etc & pagination?.. ugh
user, calendarresource fields
$filter, $search (events?$search=bert doesn't work in graph?)
