We had an email rendering issue with Outlook 2016 Pro Plus (running Windows 8) user test.
Our email contained a background image and we used the bullet-proof backgrounds method containing conditional statements.The total weight of the email is under 140k (including images).
All the litmus tests looked good across different versions of Outlook. However, for our employees using Outlook 2016 pro plus, the email content was cut-off/truncated in the preview pane. The only way to repair it was to strip out the conditional statements for the background image and use a solid background color instead.

Curious if anyone else has experienced similar issues with Outlook 2016 Pro Plus.
