Outlook AutoComplete cache

Many times I have been asked about the Outlook address auto complete cache.  This is the way Outlook provides email addresses you have sent or received mail with in the To, CC, or BCC fields in mail messages.  I thought this wasn’t possible in the past.

Not so, apparently.  This cache is stored in the “profilename.nk2″ file, where “profilename” is the name of the Outlook profile.  This file is hidden, so “view hidden files and folders” must be enabled in Windows Explorer.  It resides in the “%USERPROFILE%\Application Data\Microsoft\Outlook” folder.  Just copy this over to the new location to bring the autocomplete cache along and remember to rename the file if the destination Outlook profile name is different.

More details for this process can be found in this post at mycomputeraid.com.
