How to Combine Two Mailboxes in Outlook
Combining multiple mailboxes in Microsoft Outlook can increase your organization and productivity, and save you time. You can configure Outlook to send and receive email from multiple accounts, no matter what Internet service provider (ISP) you utilize. You don't need extensive computer knowledge to set this up. You just need to have some basic information from your ISP.
Click "Tools" at the top of the screen. Highlight and click "Options."
Click "Mail Setup." Click the "Email Accounts" button.
Click the "New" button. It is located at the far left of the box, just below the "Email" tab.
Click the server that hosts the first email account you wish to add. Click "Next."
Type in the email provider information in the boxes that pop up. The required fields and the information will vary based on the provider. You can find the proper settings by selecting the provider's "Help" or "FAQ" option. All major email providers have information about configuring with Outlook.
Type in your password. Click "Remember Password." This is optional, but since you will have multiple email accounts linked to Outlook, it allows you to avoid logging in to both accounts when you start the program.
Click "Check Names" if you are adding a Microsoft Exchange server account. Your name and server will be underlined. If it is not, recheck the information entered in Step 5. Once verified, click "Next." Click "Test Account Settings" if you are adding a POP3 account. Outlook will test your server connection and send a test email. You will see green check marks next to all tasks. If anything is incorrect, a red "X" will indicate failure. Recheck the information in Step 5.
Repeat these steps with the second email address you wish to add. Once complete and verified, all email from both accounts will be merged in Outlook.
