Microsoft Office Outlook is a multi-faceted productivity software, with many subtleties that few home users take advantage of. Outlook's email management function is probably the single feature that most home users and small business users use on a daily basis. However, it is not typically used to its full capacity. One of the great features of Outlook is that you can set up multiple email accounts in your Outlook email manager, giving you access to all your email in one powerful tool. In order to set up multiple email addresses in Outlook, follow the steps below.
Open Outlook and go to the Mail page.
Go to the "Tools" menu, and select "Options."
Select the "Mail Setup" tab.
Select the "E-mail Accounts" button.
The "E-mail" tab will be pre-selected when you come to this window. Select the "New" option on the left side of the window.
Choose your email service type. This selection defaults to "Microsoft Exchange, POP3, IMAP or HTTP", and this selection will work for most applications. Press "Next."
Enter your name as you like it to appear – the name has no effect on gaining entry to your email accounts.
Enter your email address.
Enter and re-enter your email account password. Press "Next". Outlook will test the connections, send a test email to your mailbox, and attempt to access it. Once complete, it will give you a "Success" message, and you may hit the "Finish" button.
When you return to your mail page, you will find your newly added mailbox on the left ribbon, under other existing boxes. Congratulations, you have added a new mailbox to your Outlook.
