Starting late July, 2013, Microsoft will start unlinking all accounts, of course that if you don’t use this feature, you don’t have anything to fear. But those folks who have linked accounts, the software maker will be providing the forward and send messages from other addresses features. However, you won’t be able to control more than one account with a single sign-in. The main reason for the change is because Microsoft has discovered that many users keep their primary email account information (e.g., password) up to date, but secondary accounts don’t share the same attention, and this becomes a security problem that can compromise all the users accounts. The new change shouldn’t come as a surprise, a couple of months the software maker introduced two-step authentication to make a Microsoft account more secure, but it required to unlink any account linked to a main account. The company is also working on a functionality called “move an alias” to allow users move an email address and emails from one account to another.
