We are running Notes 8.5.3 in Citrix environment with Windows 2008 R2 x64 and Citrix XenApp 6. When you save a file to a network drive (ie. pdf or word file, it takes from 15 minutes up to several hours to see it through the Lotus Notes in order to attach it into the mail. There is no problem when browsing with explore to find the file, and ONLY Notes has this issue.
