Image src attribute in email body using microsoft graph #42

Closed glensouza closed 4 years ago

glensouza commented 6 years ago

Is there sample code out there for getting an Office 365 email body with the embedded image using Microsoft Graph? So far I've only been able to get an image tag that the "src" attribute does not reflect anything that would display the image that looks something like this: <img src="cid:image001.jpg@01D3E60C.5A00BC30"> and of course, that does not display any images.

I know this is an old issue, but I wanted to provide an answer anyway.

That format in the src attribute indicates that the image is attached to the message. To render it, you must get the attachment that has that CID stamped on it and insert it in the appropriate place. The CID will be in the contentId property on the attachment.
