HI
I have Exchange 2010 and sharepoint 2010 with all our user using outlook 2007. what options do I have for collaborations between these systems if I was to install Lync 2013. I have seen posts that mention that you cannot use outlook 2007 and lync 2013 and that you would be better off installing the lync 2010 client?
1. would we be covered from a licensing point of view if we had bought lync 2013 cals but install the lync 2010 software on desktops?
2. what Cals do we require for presence to be available in SharePoint we currently have standard sharepoint cals?
3. what new features will we loose if we install 2010 lync software.
4. if our mobile users use the 2013 lync software will these be able to communicate with the 2010 users?
thanks
J
