Outlook truncating emails in Windows 10 Mobile

[javisasan]

On Windows Phone 8.1, my emails arrived complete but with no images, which is ok. But on Wimdows 10 Mobile messages get truncated at a certain weight, and if they have images the text gets cut. And trying to download them takes a life on my Lumia 535.

How can I take back the previous functionality?

Thanks in advance!
