Greetings, I have Windows Messenger (with the 4.6 update and the add-ins). I also have a cell phone account that allows 2 way SMS (text messaging). I would like to activate the option that allows buddies to send a text message to the mobile device, through their Messenger interface. The problem: Open Messenger - Tools - Edit my mobile settings Phone number is entered. Under mobile settings, the allow people to send messages ... option is greyed out. When I select the Mobile Settings button, an MSN window with the link: http://mobile.msn.ca/hotmail/confirmUser.asp?URL=/messengerok.htm&mobID=1, but displays the message, "HTTP 500: Internal Server Error. The page cannot be displayed " I have notified MSN mobile, but they have yet to provide a solution... Anyone else experience this or find a solution ? Thanks.
