As an individual I am eager to purchase Exchange Online Plan 1 as detailed on the below link.
http://office.microsoft.com/en-in/exchange/compare-microsoft-exchange-online-plans-FX103764022.aspx
Need to understand if I can buy and use this account as an individual. If yes, (a) I do not have a domain name for now, (b) what will be the default domain name I will receive at the time of buying, (c) can I start using the account immediately, and, (d) am I required to have any backend systems before I consider or process this purchase.
