Hi there
We had a major change to our network in late 2009 including netware to AD, new desktop Operating systems and a new mail system. We decided to go with live@edu for all our users - 240 staff and about 1000 of our 1360 students (not all the young ones). We did engage a microsoft partner to set up the password synchronisation with AD, so that mail accounts are created as we create users.
Have used the SSO portal kit supplied and managed to get this working - it is not flash, but i guess I could now pay for someone to make it better - kids like it though as there is seamless access from sharepoint to their email and skydrive.
Staff love outlook (most had not used it before), and I like having home versions and school versions using the client. Positive feedback from students on the skydrive and sharepoint/outlook integration.
We have no internal mail server and have had few problems with outages (one failed update to a server in some other country that Microsoft then rolled back)
Our assessment - could we recommend it - yep!
I think Microsoft are doing some serious catching up.
Cheers
