This guide will assist you with adding or Importing the AutoFill / AutoComplete file created from Outlook 2010 / 2013 / 2016 or Outlook 365 account.

This will allow the user to automatically autofill/populate an email address when composing a new email that is being sent to a previous contact.

Follow the steps below

  • Important that you make sure you have closed Microsoft Outlook

  • Click on the Windows Start Button which is different depending on the version of Windows.

    Windows 7  

    Windows 8 / 8.1 / 10

  • Then double click on Computer if using Windows 7.

    For Windows 8 or 8.1 users, type Computer and select the Computer tile

    Windows 10 just click on File Explorer which is on the menu bar or right click on Start and select File Explorer

    Windows 7

    Windows 8 or 8.1

    Windows 10

  • Then go to the following folder taking in to account that the Example_User folder is normally your user name


    The AppData folder is a hidden folder, to see hidden folders please refer to the Windows 7 & 8 – Show Hidden Files and Folders article

  • Make a backup of the Stream_Autocomplete… files before you make any changes!

  • Rename the Stream_Autocomplete…. file in this folder to oldStreaming_autocomplete…..

  • Copy the source file you saved from your other computer or Outlook version into this folder and name it the same name as the original file name from the step above.

    Otherwise if you are wanting to copy your autocomplete from a different profile you should see a Stream_Autocomplete… file that is alot larger in size.

    Take a copy of that file and rename it to your new Stream_Autocomplete file.
