NFS Server setup not working(?)

Hi.
Using Servers Ultimate to start a new NFS server on my Android device - Z ultra rooted.
I have firewall turned off both on the server and client.

First I replaced the "linker" file due to google disabling of pie
error: only position independent executables (PIE) are supported.

NFS server is able to being executed now.

192.168.1.84 = server
192.168.1.90 = client

When active I can see my client in the Server ultimate log on the android when searching the network with yast: 192.168.1.90 - New request...
But the server (android phone) says, this version (3) not handled: min=2 max=2...**

What does this mean?
I have NFS server working on Windows 7 and FreeNAS and client working on Suse so this issue is isolated to android. Not my network or my client.

Having the option to choose and setup NFS servers in the Servers ultimate app must mean its possible to use NFS on android?

Exchange Server on stock email app?

I'm coming from a 4.4 Nexus 5, where if I add an account to the standard email app I get the choice between POP3/IMAP/Exchange.
On the 5x, the stock app doens't have Exchange as an option?
I like keeping gmail (personal) with the gmail app, and the stock email app for my business mail.
How do I enable exchange?
