I ran into (yet another) annoying Outlook 2016/2013 bug today. I had an image inside a table. I had the table aligned left. When reviewing in Outlook 2016/2013, the table containing the image was clipping over the text that was wrapping around it. Essentially, it was coving up the first letter of each word that was immediately to the left of the table. Luckily, I was able to find the fix on Campaign Monitor's blog. I just needed to add some MS Outlook specific styles to the left-aligned table, like so:

<table align="left" border="0" cellpadding="0" cellspacing="0" style="mso-table-rspace:6pt;border-collapse:collapse;border:1px solid #ffffff;">
