I have a 15-user perpetual starter license.
Reading the differences beteween editions on Zimbra - Compare Products I noticed that one option for the starter edition has disappeared, '
Windows Mobile and other smartphone Contact, Calendar, Task sync' is no longer checked.
Compare to the version of may 2011 on web.archive.org:
Zimbra - Compare Products - the option is checked.

What does that mean?
If I upgrade to Zimbra NE 8, will I loose Contact, Calendar and Task sync for my mobile devices? It is working now in my Zimbra NE 7 server.
