These issues are not unique to emails sent from Envoke, the glitches are with Outlook itself. 

Thin lines are inserted in emails in Outlook 2016 (or 2019) on Windows. This is a known bug with Outlook 2016's old Microsoft Word based rendering engine. 

Also in Outlook 2016 running on Windows, not all line heights are working as intended. For example line heights of 1.3 and 1.8 look the same.

When headlines wrap in Outlook, often a larger line height gap will appear than in other email programs.

In other cases, Outlook may add 20 - 30% more line height than expected.

Displaying transparent PNGs doesn't work reliably.

Multi-column layouts don't display well in the Outlook App: the columns don't stack correctly in mobile view. If Outlook App display is critical to you then you should switch to a single column layout that isn't dependent on multiple columns stacking on small screens.

Select versions of Outlook (360, 2019 and 2021) might show a band of background colour around partial width, left or right aligned images when using image blocks. An example of this is a small logo aligned right in the message header. The recommended workaround is to create a header image that is the full width of the header block (660px), and centre aligned, to display the header without this artifact.
