When you start Microsoft Outlook 2013 or Outlook 2016 for the first time, your nickname cache (stored in the profilename.nk2 file) is imported into a hidden message in your default message store.
Note profilename is the name of your Outlook profile.
For example, if you are using a Microsoft Exchange account, the nickname cache is imported into a hidden message in the Exchange mailbox.
Note Outlook 2007 and earlier versions store the nickname cache .nk2 file in the following folder.
Note If you have multiple Outlook profiles, the nickname cache from each profile is merged into your new Outlook 2013 or Outlook 2016 nickname cache on the first start of Outlook by using that profile. Therefore, you may find more than one .nk2 file renamed to .nk2.old.
