If you are interested why it didn't work before:

dcerpc endpoint servers = epmapper, mapiproxy, dnsserver

Is turning off this lot:

wkssvc, rpcecho, samr, netlogon, lsarpc, spoolss, drsuapi, dssetup, 
unixinfo, browser, eventlog6, backupkey

If you run 'samba-tool testparm -v' , you will get all the defaults as 
well as what is in smb.conf, amongst which is:

dcerpc endpoint servers = epmapper, wkssvc, rpcecho, samr, netlogon, 
lsarpc, spoolss, drsuapi, dssetup, unixinfo, browser, eventlog6, 
backupkey, dnsserver

So by setting 'dcerpc endpoint server' as you did, you have turned all 
the rest off, try this line instead:

dcerpc endpoint servers = +mapiproxy
