Office365 REST API - Creating a calendar event with attachments

Question

I am unable to create a calendar event with attachments using Office365\'s Rest API. Creating events without attachments is not a problem. Trying to create events with attac

Answer 1

I see this too! I'm able to post an attachment to the event after it's created, just not include one with the initial create payload.

So as a workaround, you can create the event, then do

POST /me/events/{eventid}/attachments

{
  "@odata.type": "#microsoft.graph.fileAttachment",
  "name": "$(fileName)",
  "contentBytes": "$(base64EncodedString)"
}

I'll check with the calendaring folks on this to see why it's not working during the initial POST.
