Okay, I have a Horizon 7.13.1 environment with FSLogix and Instant Clones. There are a number of AppVol applications (non-writable) that are added depending on users group membership. Office 2016 is part of the base image. When someone saves or modifies a document in one of the AppVol applications (like foxit PDF editor) and then in Outlook creates a new email to which they want to attach the file, it doesn't show up under the "Recent documents" dialogue -- the user has to browse to the folder where the document was saved and attach from there. Is there a way around this? Is this because Office is in the desktop image and the other app is in an AppVol and they don't communicate like that?
