I've have an NE version 6 server that's using the free 10 user license that was available with the zimbra appliance (now MIA).
I want to upgrade to version 7, but I read some where that my license will no longer work. This means I can either pay for the NE starter pack or go to the OSE.
If I move to the OSE I'll lose ActiveSync which would really suck.
There appears to be two main alternatives: Z-Push and ZeXtras Mobile Module.
What experience does anyone have with these two and how do they compare with Zimbra's NE ActiveSync?
