I have a list with a rich text column. When I add a hyperlink (using the toolbar) that points to a network location, SharePoint is stripping the URL from hyperlink. Hyperlinks with URLs to web sites are fine. I have tried both:
I get the same result. The data is display as a link but there is no URL embedded in it. When I open the item to edit it, only the text remains
Edit: I can get it to work by just putting in the UNC directly as text, as long as it does not contain spaces. I tried to use %20 for spaces but the link includes the encoded chars in the path when you try to open the it.
