Export/Import Suggested Contacts - autocomplete cache - in OUTLOOK 2010

Hi,
 I am going to "disable" an existing user mailbox in Exch 2010 and create a new mailbox with the same username.  When I did this last time, I noticed two problems:
(1) After importing PST into the new mailbox, the user complained about suggested contacts would not come up as he creates a new email and enter the email address. So I like to know how to export and import Suggested Contacts. Even if Suggested contacts did exist in his C drive, when you create a new outlook profile, the new account did not recognize existing Suggested Contacts associated with old mailbox. NK2 was much simpler.

(2)  After I created new mailbox and imported PST into the account, people (on the same network) would get "undeliverable" emails when sending emails to this new mailbox even if username was the same. I learned later that I needed to add X.500 email address to the account instead of waiting for global address book is downloaded into each user's OUTLOOK.

Thank you.

In Outlook 2010, Nickname (.nk2) files have been replaced by the AutoComplete Stream, which is part of the Exchange Mailbox, or pst/ost file.
 
Nirsoft have made a tool called NK2Edit, which despite it's name, can read and write both .nk2 nicknames and stream auto-complete lists.
 
You can grab it from http://www.nirsoft.net/utils/outlook_nk2_edit.htm - run it on the old mailbox, save it as an .nk2 file, then on the new mailbox, either import the .nk2 file (Pre 2010) or click file > Copy to AutoComplete List.
 
2 potential stumbling blocks:

NK2edit will only collect the names from the primary mailbox in the default profile, so you may need to fiddle around in outlook if you have more than one account or profile
 
After firstrun, Outlook 2010 needs to be started from the run command as "outlook.exe /importnk2" - see http://support.microsoft.com/kb/980542

I downloaded NK2Edit and ran it.
Whether I open OUTLOOK with old profile (before mailbox disable) or with new profile (with new new mailbox), NK2Edit shows the names and email addresses of those people that used to come up automatically when I select recipient email address.

Can you explain again how to transport this list to the new outlook profile?

I have already tried "Export to Message stroe (outlook 2010)" and did not make any differece.

You may have to do this longhand by copying the file from the old profile to the new

See the link below that explains where the files are and how to move/rename them

(Make sure to save original files with changed extension (say .old) as a safety backup )

NK2 BackupThis is how I ended up doing it as I had another opportunity to re-create an user mailbox.
Before removing his mailbox, I ran NK2EDIT on the computer with OUTLOOK 2010 and created NK2 file beginning with "Steam_Autocomplete_xxxxxxx.dat.NK2Edit.bak".
Then I renamed this file to "Outlook.NK2".
I disabled the mailbox and re-created a new mailbox for the user.
I created a new user profile "OUTLOOK", opened OUTLOOK 2010, imported PST file and copied OUTLOOK.NK2 into the appropriate folder.
Then I opened Start/Run and typed outlook.exe /importnk2 and almost all entrieds from his old mailbox got transferred to the new mailbox/outlook.
