Hello all. Wondering if anyone has dealt with Outlook 2016 inserting a 1px horizontal line into the body of the email. If so, how did you get around it in RED? Here is a link to the Litmus forums discussion the issue.

Didn't know why the line showed up.

I get that but not with some basic old static files I have, just since things have been responsive. I can fix it sometimes with changing heights and so on as mentioned on litmus, but it's very random, and doesn't always match against Outlook '16 on other computers.

Ok..finally found a solve for this.

<!--[if gt mso 15]>
<style type="text/css" media="all">
/* Outlook 2016 Height Fix */
table, tr, td {border-collapse: collapse;}
tr { font-size:0px; line-height:0px; border-collapse: collapse; }
</style>
<![endif]-->

Thank you sooooo much for figuring this out. I was having the same issue.

For me, this didn't show its ugly head until I did a Save-As, made an adjustment, and tested the email. I saw one row with this issue. Now, when I did another Save-As from the original file, made an adjustment and tested it. Then I saw two rows with this issue.
