I’ve had to help people through a decent number of computer or profile migrations at work and one of the items that often gets overlooked is the Outlook nickname file. This file is referenced by Outlook when offering auto-complete suggestions as you type in the To, Cc, or Bcc fields, based on who you’ve sent emails to in the past.
Since Outlook 2010, Microsoft changed from using an separate nickname (nk2) file to having the entries be in a hidden message in your default message store. I haven’t confirmed this, but documentation suggests that if you have a nickname file in place when you launch Outlook 2010 for the first time, it will import the entries, automatically. After that, you will need to do it manually. Here are the steps that need to be taken to do so, as provided by Microsoft support (http://support.microsoft.com/kb/980542):
To import .nk2 files into Outlook 2010, follow these steps:
- Make sure that the .nk2 file is in the following folder:
Note The .nk2 file must have the same name as your current Outlook 2010 profile. By default, the profile name is “Outlook.” To check the profile name, follow these steps:
- Click Start, and then click Control Panel.
- Double-click Mail.
- In the Mail Setup dialog box, click Show Profiles.
- Click Start, and then click Run.
- In the Open box, type outlook.exe /importnk2, and then click OK. This should import the .nk2 file into the Outlook 2010 profile.Note After you import the .nk2 file, the contents of the file are merged into the existing nickname cache that is currently stored in your mailbox.
Note The .nk2 file is renamed with a .old file name extension on the first start of Outlook 2010. Therefore, if you try to re-import the .nk2 file, remove the .old file name extension.
I think the nk2 file location has moved around a little in the past, but you should be able to locate it in the same place (%appdata%\Microsoft\Outlook) that you would need to have it placed on the new computer or profile.
