I sometimes use Open with Explorer to navigate through our file structure. It is painfully slow. My IT company say this is because you shouldn't use the Open with Explorer view and should just use the SharePoint interface but this is impractical in some cases (such as moving files, inserting multiple attachments/hyperlinks in emails). I don't understand why Microsoft would include this feature if it shouldn't be used.
I have turned off 'Automatically detect settings' in Internet Options
Any help would be greatly appreciated
