Outlook 2013 logoIf you are familiar with Microsoft Outlook 2010 or earlier versions of Microsoft Outlook, the following list describes features and functionality that have been discontinued or changed in Microsoft Outlook 2013. 


  • Exchange Delivery to Outlook Data Files (.pst) Upon upgrading to Outlook 2013, profiles that are configured to delivery Exchange Server account items to an Outlook Data File (.pst) continue to see the file in the Navigation Pane. However, all new items are delivered to an offline Outlook Data File (.ost) and Cached Exchange Mode is turned on for the Exchange account.


  • Import/Export from applications The Import Internet Mail Account Settings and Import Internet Mail and Addresses options are discontinued. When exporting to Outlook 2013 data to a file, tab separated values, Microsoft Access, and Microsoft Excel aren’t supported. To export to Excel, we recommend exporting data to a comma separated values (CSV) file and then importing the CSV file in Excel.




  • ANSI PST creation The Outlook 97-2002 Data File (*.pst) option isn’t available when creating an Outlook Data File. This change doesn’t impact the automatic creation of ANSI offline Outlook Data Files (.ost) used to support alternate display names for Asian languages.


  • Send/Receive Groups In Mail, on the Send / Receive tab, in the Send & Receive group, the Send/Receive Groups command is replaced with Send/Receive. The Download Address Book command, previously on the Send/Receive Groups list, is now on the ribbon in the Server group. Any previously customized Send/Receive groups are converted to a single group, previously known as All Accounts. If a custom server connection interval had been configured for the All Accounts Send/Receive group, this setting remain in effect for Outlook 2013.


  • Dial-up Networking support Dial-up networking should be configured in Windows. After upgrading to Outlook 2013, default (LAN) connection settings are applied. On the Send / Receive tab, in the Preferences group, the Dial-Up Connection command is removed. In Outlook options, in Advanced, the Dial-Up connections section is removed. When modifying an Exchange Server account, More Settings opens the Microsoft Exchange dialog box. The Connection tab is removed. Outlook Anywhere configuration which was accessible on the Connection tab now appears on the General tab.


  • Exchange Server Download Headers and Then Full Items mode This feature is discontinued. After upgrading to Outlook 2013 if this option was selected, it is automatically changed to Download Full Items.


  • Exchange Server classic offline mode This feature is discontinued. Exchange Server accounts can be used online or in Cached Exchange Mode.
