I personally use Skype as my default IM client and that also integrated with Outlook at home. At work, we use Skype for Business and there Outlook integrates with Skype for Business.
I recently upgraded my home computer to Office 2016 via our company’s Office 365 licensing and now Skype no longer integrates with Outlook 2016. When I log on with Skype for Business at home, I found out that it now integrates with Outlook instead.
Do I need the Home or Personal edition of Office 2016 for integration with Skype or can I somehow set which IM client should integrate with Outlook?
Both Skype and Skype for Business (previously known as Lync) as well as Cisco Jabber can integrate with the IM functionality available in Outlook 2010, Outlook 2013 and Outlook 2016. This means that you can see people’s Skype or Jabber availability, reply to an email via an IM or directly start a call or chat all from within Outlook.
When you are using Skype or Jabber and then install an Office edition that includes Skype for Business, Skype for Business is set as the default IM client in Windows. Similarly, when you are using Skype for Business and then also install Skype or Jabber afterwards, it will set Skype or Jabber as the default.
It would have been nice if there was an easy way to select your IM client for Outlook straight from within Outlook or the IM client itself. Sadly, this is not the case, but you can still set it directly via the Registry.
IM Providers Registry key
The Registry key which stores which IM client can integrate with Outlook is:
Below this key, you’ll find several sub keys which represent the IM clients that you have installed on your system (and registered themselves as such).
IM Providers key, you’ll see a value called
DefaultIMApp. This value should correspond to one of the sub keys. When you change the value of
DefaultIMApp, restart Outlook and your new default IM application and Outlook should now use that as the application for IM integration.
When you want to use Skype for Business as the default, the
DefaultIMApp value should be set to
Lync as that was the previous name of Skype for Business and that name is still being used in several places for backwards compatibility.
If you don’t want to modify the Registry yourself, you can download the zip-file below. Within it, you’ll find ready made reg-files to set Skype, Skype for Business (Lync), Communicator or Cisco Jabber as the default IM application. Simply double click the correct reg-file to automatically set the value.
Various IM clients can integrate with Outlook but choosing a default requires a Registry fix.
Note: Changing the default IM provider also affects the other Office applications of course. For instance, when you use the Contact Card in Backstage or the comment section in Word.
Supported IM clients
Please realize that you can’t simply pick any IM client and expect its integration to work in Outlook or other Office applications. If it doesn’t offer any Office integration features, setting this key to that application will disable the Reply with IM, chat, call and on-line availability functions in Outlook.
Amongst the supported IM clients are: Skype, Skype for Business, Lync, Office Communicator 2007 R2 and Cisco Jabber. The level of integration depends on a combination of the IM client being used and the version of Outlook.
Note: Windows Messenger got discontinued so setting MSN Messenger as the default is no longer supported.
