This article illustrates how to configure an POP3/IMAP account and how to send as a domain/user alias in Outlook 2013. If you have user aliases set up for your account, this section describes the steps necessary to send email using the alias address.

For more information, please read the differences between a user alias and a domain alias. If you do not have an alias name for your account, please contact your company network administrator to Add an Alias to Your Zimbra Mailbox.

POP3 and IMAP Account Settings

1. Open Outlook 2013 and Click on the File tab located in the upper-left hand corner.

2. Under the Info section, select the Account Settings drown down arrow to click Account Settings.

3. When the Account Settings window appears, select new to begin creating a new account.

4. When the Add Account window appears select E-mail Accounts and choose Next to Select Manual setup or additional server types. Choosing Next will allow POP and IMAP email services to be selected.

5. You will now need to configure your account settings. These Settings determine the type of account you are creating IMAP, POP3 or Alias SMTP POP3.

6. Click the More Settings button.

7. Click on the Outgoing Server tab.

8. Check the "My outgoing server (SMTP) requires authentication" box.

9. Click the Advanced tab.

10. In the Outgoing server (SMTP) port box, enter 587.

11. Click OK.

12. Click on the Next button to test your account settings and finish the account creation.

POP3 Settings When Sending as an Alias

1. When 'Sending' as an alias, you will want to alter the Email Address field to the alias address rather then the primary address. Additionally, you will need to remove the Incoming mail server information to avoid in inbox duplication. We recommend simply placing "xxxxx" as a substation. Click on More Settings.

2. Within the Settings Window, Under the General tab, type the alias Alias Address into the Reply E-mail field. When completed move to the Outgoing Server tab.

3. Within the Outgoing Server tab, check the box that says My outgoing server (SMTP) requires authentication and select the radial button to Logon using username and password. You will want to place the primary login mailbox address and password in these fields.

4. Click OK to close the Settings window then next to create your account.

Please Note: When Outlook is first launched all accounts perform a Send/Receive. Alias SMTP configured accounts produce an error when attempting to contact the inbound server. The next steps prevent the errors that occur on Send and Receive.

1. Within Outlook 2013, select the Send / Receive tab from the Ribbon. Under the Send/Receive Groups drop down menu, choose Define Send/Receive Groups.

2. Under Group Name, select the All Accounts group and choose edit. Deselecting the Receive Mail Items check box will remove the error and disable the send / receive process upon Outlook start-up.

That's it! In Outlook, create a new email message. Next to the send button, you will see an Accounts button with a drop down selection of the accounts on that allows you to select which email account the email comes from.
