The AutoComplete information is imported from the IPM.Configuration.Autocomplete_<_hexadecimal code_>.msg, where the placeholder<_hexadecimal code_> represents a long string of numbers and letters. ## Copy and import an .nk2 file ### Step 1: Copy the Auto-Complete file from the old computer 1. Because the default folder is hidden folder, the easiest way to open the folder is to use the command **%APPDATA%\Microsoft\Outlook** in the Windows **Search** box (or, browse to C:\Users\_username_\AppData\Roaming\Microsoft\Outlook). 2. In the Outlook folder, find your Auto-Complete List (.nk2) file. > [!Note] > By default, file extensions are hidden in Windows. To change whether file extensions are shown, in Window Explorer on the **Tools** menu (in Windows 7 or Windows Vista, press the ALT key to see the **Tools** menu), click **Folder Options**. On the **View** tab select or clear the **Hide extensions for known file types** check box. 3. Copy the file to the new computer. The file is small and can be placed on a removable media such as a USB memory stick. ### Step 2: Copy the Auto-Complete file to the new computer 1. On the new computer, in Control Panel, select or double-click **Mail**. **Mail** appears in different Control Panel locations depending on the version of the Microsoft Windows operating system, the Control Panel view selected, and whether a 32- or 64-bit operating system or version of Outlook 2010 is installed. The easiest way to locate **Mail** is to open Control Panel in Windows, and then in the **Search** box at the top of window, type **Mail**. In Control Panel for Windows XP, type **Mail** in the **Address** box. **Note:** The **Mail** icon appears after Outlook starts for the first time. 2. Select **Show Profiles**. 3. Make a note of the name of the profile. You will need to change name of the .nk2 file to match this name later. 4. Copy the .nk2 file to the new computer in the folder in which Outlook configurations are saved. Because the default folder is hidden folder, the easiest way to open the folder is to use the command **%APPDATA%\Microsoft\Outlook** in the Windows **Search** box (or, browse to C:\Users\_username_\AppData\Roaming\Microsoft\Outlook). 5. After the file is copied to the folder, right-click the file, click **Rename**, and change the name to match the profile name that you noted in step 3. ### Step 3: Import the Auto-Complete List You are now ready to start Outlook and import the file, but you must start Outlook with a special one-time command. - Type `outlook /importnk2` in the Windows **Search** box and then press Enter. The Auto-Complete List should now have the entries from your other computer when you compose a message and begin typing in the **To**, **Cc**, or **Bcc** boxes.
