DMARC: Domains hosted with Microsoft can be configured to use the hosted domain in the envelope address. This allows SPF to apply to DMARC checks.

DKIM: DKIM can be configured for Office 365. First, try: http://o365info.com/how-to-enable-outbound-dkim-signing-for-your-domain-in-office-365-part-5-of-5/ If that doesnt work, see: http://blogs.msdn.com/b/tzink/archive/2015/10/08/manually-hooking-up-dkim-signing-in-office-365.aspx
