Hello,
I was setting up the trial on Office 365. I had a page that offered a check box for Exchange and Lync. I did not want to incorporate these servers at this time. I checked the boxes and hit next. The guide switched to a your complete page. My question is if I decide to switch and use Exchange and Lync would it be possible or would I need to start a new subscription. I have the E3 plan (Non Profit is cheaper for local Office installs). Since I am payning for Exchange and Lync how hard would it be to start them in this subscription?
