Ok so you have signed for Office 365 and would like to use Lync on your work laptop, but your company has not moved to Lync OR you have Lync for work but cannot add people outside of your organization and you would like to use your personal Lync, then what options do you have? This is part of my Office 365 blog post series
No worries, you can have OCS/Lync or Lync/Lync work in tandem. This is what I have on my work laptop
What I did was to install Windows XP Mode and configure Lync /Office 2010, the works you know in XP and I was all sorted!
Download Windows XP Mode and off you go!
Note: Assuming your OS is Windows 7
