A client of mine is having issues adding attachments from network shares on the server. Local attachments work fine. The root directory of the network share loads fine, subfolders take a min or so to open. Accessing the shares outside of Outlook works fine. There are no errors in the event log. They are using eEye Blink for AV and I have tried disabling it completely and it has no add-ins listed in Outlook. Any ideas?
