Same kind of problem on my Mac. I'm running OS 10.11.6. and an Epson WP4530 printer. My envelopes printed fine until I installed 365. Now on a #10 envelope, the return address is 2-1/4" inches down from the top, and the sender address of off the page -- this even though everything appears as it should in the preview in the print dialog box. (It all prints on 8.5"x11" pieced of paper.) I spent an hour with tech support, first on chat, then on level one phone support with screen sharing, but they could not help me. I'm now waiting for level two support to call me.
