Thanks for the fast relies 
I was reading the Sogo 2.2.15 is available to test thread and see that Outlook 2010 needs OpenChange (according to the SOGo image). Will Outlook 2010 work with NethServer & SOGo after the initial install (Windows guy still learning the Linux vocabulary).
I plan on doing the install on Proxmox VE. Would it be better to have a couple of instances of NethServer running - one for mail server & activesync and one for the roaming profiles or just have everything run on a single build?
