Outlook Desktop, setSelectedDataAsync sets incorrect color for cell borders in a table

[DmitryKostochko]

In an Outlook add-in for compose mode, we use the setSelectedDataAsync method that inserts HTML with incorrect result, the color is not applied to all borders of a cell.

Expected Behavior

All borders of a cell shall have the specified color.

Current Behavior

Please see the screenshot below.

Steps to Reproduce, or Live Example

Create a new email in Outlook Desktop and execute the following code:
Office.context.mailbox.item.body.setSelectedDataAsync(
'<p>Table</p>' +
'<table style="width: 100%; border-collapse: collapse; border-style: solid; border-color: black;" border="1px">' +
'<tbody>' +
'<tr>' +
'<td style="width: 50.0%; border: 1px solid red;">border: 1px solid red</td>' +
'<td style="width: 50.0%; border: 1px solid black;">text</td>' +
'</tr>' +
'<tr>' +
'<td style="width: 50.0%; border: 1px solid black;">text</td>' +
'<td style="width: 50.0%; border: 1px solid black;">text</td>' +
'</tr>' +
'</tbody>' +
'</table>',
{ coercionType : 'html' },
function (result) { console.log(JSON.stringify(result)); }
);

As you can see, the borders of the first cell are not red.

HTML in Outlook is rendered via Word, which doesn’t always behave the same as Web based HTML renders. We have made the owning team aware of this report, but it is unknown if this will be addressed.

In the meantime, it is likely you should rework the HTML to workaround this issue. Which will also have the benefit of working with older versions of Outlook/Word even if the issue is addressed.
