Click the tools icon and select File > Exit. In the Options window, choose Personal and clear Automatically start the app when I log on to Windows and Start the app in the foreground and select OK. Still determined not to have the status / presence indicator showing in Outlook, I had to find something else to set the DefaultIMApp value to… I picked ‘NotSkype’ and I have been happy since. Stop the automatic Skype for Business startup: Open Skype for Business and click the tools icon and select tools > options from the drop down menu. Skype decided to reinstall itself as the default IM app and insert the annoying grey boxes again. Woohoo – until I restarted Skype and Outlook. My first attempt at removal after cruising through the Skype menus was to delete the newly added registry key at \HKEY_CURRENT_USERS\Software\IM Providers\DefaultIMApp (Skype sets the value to ‘Skype’ and also adds some sub keys). It might be great for some people but the little grey boxes annoy me and it annoys me further that there isn’t a quick way to remove the integration from Outlook. Upon reopening Outlook, you have a presence indicator to the left of each email address (some people have this already with Microsoft Lync). Who wants a Skype toolbar? Now with version 6.1 and 6.2 Skype automatically integrates itself with Outlook 2010 or 2013.

They sneak in more crap with each new version. While I am a big fan of Skype, I hate downloading updates to Skype.
