Transfer Outlook 2010 Auto-Complete to new computer

MSOutlook2010-AutoComplete1

Outlook has an function to suggest email addresses as you start to type them in, commonly known as the ‘auto-complete’ feature.

It works by keeping a list of people you’ve emailed so when you go to write a new email address and start filling out the ‘to’, ‘cc’ or ‘bcc’ field it will suggest the similar email addresses.

Previous versions of Outlook stored this list in a file called ‘Outlook.nk2’ however Outlook 2010 now uses an XML file called ‘stream_autocomplete’.

Transferring the file to a new computer or user profile is a simply copy and paste process:

Please Note: Outlook needs to be closed

  1. First you need to find the file. The location may be different depending on if you’re using Windows XP or Windows 7/Vista:

    2. Windows 7 / Vista – C:\Users\%username%\AppData\Local\Microsoft\Outlook\RoamCache
