The Outlook plugin displays the same way as the web version, it is no longer condensed for optimal viewing in Outlook.
We are having a few issues with our Outlook plugin and this would be one of the issues. We are working on it as best we can. Please try logging out, closing Outlook. Clearing the cache for IE, and re-opening.
If that does not help, please try this updated version. https://d2dq6e731uoz0t.cloudfront.net/27d69392edce0cbd2d7128b9c74d070d/as/OutlookTodoist.Adx.exe
