I was having the same issue too, only in Outlook 2016, so thought I'd share my problem and solution in case it helps anybody else.
In our email boilerplate we narrowed it down to removing all font styles from any <td> elements, such as font-weight, font-size etc, and instead applying those styles directly to typography elements and <spans>.
We only had those styles down as a fallback, so removing it fortunately didn't impact the email design. This solution works for us with tables of any height (tested on over 700px height).
Feel free to check it out and use our boilerplate at Cogentro.com.
