End users can connect with their mailbox using many clients via POP3 or IMAP. This article explains how to connect to a mailbox using Outlook 2013 via IMAP.
1) Open Microsoft Outlook 2013.
2) On the File tab, click Account Settings. The Account Settings window is displayed. The E-mail tab is opened by default showing all your set up e-mail accounts (if there any).
3) Click New... The Add Account Wizard starts. Select E-mail Account and click Next.
4) Select the Manual setup or additional server types radio button at the bottom of the Wizard screen, and then click Next.
5) On the Choose Service page, select POP or IMAP, and then click Next. Enter the Exchange Server configuration parameters in the appropriate fields. For help finding your configuration parameters, see this article.
6) Click More Settings. A multi-tabbed dialogue box is displayed.
7) Move to the Outgoing Server tab, and then select the My outgoing server (SMTP) requires authentication checkbox. Then click Use same settings as my incoming mail server.
8) Move to the Advanced tab. Advanced properties of your e-mail account are displayed. Configure them as follows:
Under Incoming server (IMAP), next to Use the following type of encrypted connection, select SSL in the drop-down list.
Under Outgoing server (SMTP), next to Use the following type of encrypted connection, select TLS in the drop-down list.
9) Click OK to save your changes.
NOTE: Port 25 (Outgoing Server) is selected by default. Some service providers block this outgoing port. If the configuration test fails or you have trouble sending outgoing mail via this port, try changing it to 465 or 587.
10) On the POP and IMAP Account Settings page, click Next. After Outlook tests your account, click Close to close the Test Account Settings dialog box.
11) Click Next, and then click Finish.
After following the above steps, you have configured Outlook 2013 to connect with your mailbox via IMAP.
