I can't open any links in my Windows Mail. I get an error message saying "Application not Found" whenever I try. Does anyone have any ideas how to sort this out? Thanks.
What is 'Windows Mail'? Are you referring to Microsoft Outlook? Or do you read your mail through your browser? Did you install/uninstall anything about 2 weeks ago, around the time that the problem started happening?
I'm guessing you upgraded your old Hotmail account to the full version of [broken link removed] Hotmail, using the preview pane layout familiar to users of MS Outlook?
If so, attachments, pictures, and links in messages are blocked by default, and you'll need to change this setting in your preferences, or revert to the 'classic' view.
