Several months ago, when setting up one of the aliases on my hotmail account in outlook.com, I typed in a name, which apparently contained an apostrophe.  I didn't think catch it at the time and the program did not challenge it.  It accepted the name and set it up with the apostrophe.    I just now caught this and when I try to setup another alias for the same name, without the apostrophe, it says the name is already assigned.  While the account with the apostrophe works,  I believe the account without the apostrophe is mine but I can't get to it.  Who do I contact to get this resolved?
