We have encountered an issue where when end-users click a direct link to a document in SharePoint 2007 that is shared with them via email the document opens in protected mode and then when the user clicks
Edit Document they see the message below.
We're having trouble connecting to the server. If this keeps happening, contact your help desk.
Our scenario is that we use Citrix VDI desktops with IE 9 32-bit and not all of the users are experiencing the same issue even though their desktop sessions are identical.
How do we begin to troubleshoot this?
