Peggy, MSN is apparently messing with their servers again. You are the second person who has complained of that problem today.
Since you were able to write and send a message, you are apparently "in". You can always go get another hotmail passport for use now and fix the old one when all this mess settles down. We don't know when that will be, though. If you get a new passport, change your name slightly, with digits or extra letters, so it will be different than the current one.
