My organization asked us to support a limited Microsoft Office license that only allows access to portal web applications, such as Excel, Office, and Outlook online. The only inconvenience is that Outlook does not notify the user when a new email is in the inbox. My end-user expects a sort of number to appear on the tab similar to what Facebook provides.
I tried looking at the Chrome, Firefox, and Internet Explorer options but could not find a third-party application I felt comfortable installing onto a client's computer.
Is there an obvious notification solution that doesn't require the installation of third-party "free" extensions on a browser?
