Email forwarding automatically sends messages from one account to another. Any new email that arrives in your Hotmail account (or another Microsoft email account accessed through Outlook.com) will be sent to that address. Do this if you have a Hotmail account or a secondary Outlook.com email account and don't want to log into those email accounts to check for messages.
How to forward messages from Hotmail to another email account
Windows Live Hotmail is part of Outlook.com, so forwarding your Hotmail email to another email address is done through Outlook Mail. When you forward these emails to your Gmail, Yahoo, or other Outlook.com email account, you will still receive the messages, but you won't have to check the accounts all the time.
To forward your Windows Live Hotmail to another email account, follow these steps:
Sign in to your email using Outlook Mail.
