Microsoft is currently working on a fix for users experiencing issues
with clicking links in the Office Web App. When the link is clicked
nothing happens. As a workaround, affected users can right-click the URL
and open it in a new tab or window. Additionally, if the message is
opened into a separate window, clicking on the URL will work as
expected.
