MIME format support for Outlook mail and attachments, translate item ID APIs are now available in Microsoft Graph v1.0

Today, we’re excited to announce  general availability of the following Microsoft Graph APIs:

You can now use these APIs in Graph v1.0 to implement production apps that require access to the raw contents of an email message or an attachment. You can download file attachments in binary format or item attachments in MIME format. Also, you can translate the format of identifiers of multiple resources by specifying the source and target ID types.

These APIs had been among our top user asks and we’re happy to roll these out on v1.0 endpoint worldwide. You can access these APIs on the v1.0 endpoint by using syntax like the following:

GET https://graph.microsoft.com/v1.0/me/messages/{message-id}/$value 
GET https://graph.microsoft.com/v1.0/users/{id | userPrincipalName}/messages/{message-id}/attachments/{attachment-id}/$value
GET https://graph.microsoft.com/v1.0/me/translateExchangeIds

Try them out using Microsoft Graph Explorer.

If you have any feedback or suggestions for these or other APIs, please let us know via the Uservoice forum.

Happy coding!
