Rregarding Citrix and roaming users, I have found a support document (http://www-01.ibm.com/support/docview.wss?rs=475&context=SSKTWP&context=SSKTMJ&context=SSRNU3&context=SSRNUY&q1=citrix&uid=swg21158619&loc=en_US&cs=utf-8&lang=en) that states clearly: “The Roaming User feature and/or Roaming User functionality of Notes/Domino is NOT supported in a Citrix environment”.
Will roaming users on a Citrix platform be supported in Notes 8.5?
