I just installed Office 2013 and one thing I noticed is that Outlook now has two icons on the Taskbar when it is open. If the program is closed, only one icon is displayed.
Any additional Outlook windows also group to this icon so basically the first Outlook is only being used to open Outlook.
How can I get rid of this extra Outlook icon on the Taskbar?
There are various scenarios where this could happen, like with Outlook or Office upgrades and depending on how the initial shortcut was created.
When it happens for all your applications or you see an Outlook icon for each Outlook window that you open, then it is probably caused by a Taskbar setting.
Luckily, it is really easy to solve this for either situation.
Only the Outlook icon duplicates
When only the Outlook icon duplicates when you open Outlook, it most likely depends on the shortcut itself. To solve this, right click the Outlook icon that actually holds the open Outlook windows and pin that one and unpin the other one.
After you’ve pinned the correct Outlook icon, you should also see the Tasks shortcuts in the right click menu.
Only pin the Outlook icon that actually holds the open Outlook window.
All application icons duplicate on the taskbar
When you get a new application icon for each windows that you open, you probably have your Taskbar properties set to “Never combine” or “Combine when taskbar is full”.
To solve this, right click on an empty spot on your Taskbar and choose Properties. In the dialog that comes up, set the dropdown list for the “Taskbar buttons” to: Always combine, hide labels.
For a clean Taskbar, set the buttons option to: Always combine, hide labels.
