Works fine with MS O365 Exchange, but I think it's all about making sure SES is all set up correctly in your name servers with SPF and DKIM records which is what DMARC enforces. Before I even enabled SES I migrated name servers to Route53 and SES auto configured the necessary records.
I was shocked when I saw Route53 charges for DNS, as I think I've always just used a free service, but at the price of a can of soda per month I suppose it's worth it :-)
