I am currently have prepared a library with a few thousand files which is driven completely by metadata and it works AMAZING, however, I get a lot of issues with metadata library if I am trying to send someone a file via email, or upload a file from email.
To do these tasks I always have to download the file to my computer and only then I can drag and drop to SharePoint or Outlook. I tried to use link attachment but then it just throws me a list of files with no possibility to filter on metadata. Is there any way to make fully Metadata driven library work at all?
