I can... but I got an answer from Microsoft. Windows/Office update KB4011039 is at fault. I have uninstalled that update and things display properly now. From the description of the issue there, vertically merged table cells do not display their contents in Outlook or Word with that update installed. They plan to include the fix in the October monthly update rollup.https://support.microsoft.com/en-us/hel ... -kb4011039
If you still want to see the issue in action, I can send you screen captures with and without the update installed, as well as the XML source in the received email.
