NK2 not working

Jarryd - 04 Dec 2006 10:12 GMT
Hi,

I have a user who cached nicknames are not working.  It seems to have reset
itself as it can only remember addresses that have been sent to this
morning.  However, if I look in the file (which is 1MB big) I can see the
list is jam packed full of addresses.  Why can't Outlook read them.  I have
tried to recreate the profile by deleting it using the Mail program, and
then deleting all the profilename.* files from app_data\ms\outlook folder,
then recreating the profile with the same name, sent an email to recreate
the nk2 file, closed Outlook and copied the original 1MB nk2 file to the
folder to overwrite the newly created one.  This hasn't worked.  Please
help.

TIA,

Jarryd

When you recreated the new profile, what didn't work? You will have an empty
NK2 file at that point.

Hi Russ,

I recreated the profile.  After sending a message an empty NK2 file was
created.  I copied the original 1MB NK2 file to the profile folder,
overwriting the "empty" one.  I then opened Outlook, created a new message
and typed a letter in the To field.  Unfortunately it didn't suggest
anything and I know that it should have.

Best regards,

Charles

Hi all,

For anyone out there that has suffered this problem I have a solution for
you.

1. Download NK2.info from http://www.nk2.info/
2. Open profilename.nk2 file with NK2.info and export to CSV.
3. Delete the profilename.nk2 file with Outlook closed.
4. Open Outlook and create a temporary folder in your Contacts folder, e.g.
TMP-CONTACTS.
5. Import CSV fileinto temporary contact folder.  (You might want to open it
and edit / clean it up.)
6.Take Oultook offline by disconnecting it physically from the network,
create an email message and send it to everyone in the temporary contacts
folder.
7. Close Outlook (which will save all the addresses to the newly created NK2
file), and reopen it and delete the message in the Outbox before
reconnecting to the LAN / internet.

HTH.

Renaming the old NK2 file to match the new profile is easier.

Well I would expect that. You cannot overwrite an NK2 file. You would have
to rename the old file to match the new profile.

Unless the NK2 file it corrupt, which may happen any time Outlook fails
to shutdown properly. In that case using my program (NK2.info) could
prove helpful.

NK2 files rarely become corrupt. The links to them become corrupt
frequently. Recreating the profile fixes that.

Russ,

I think in your experience it may be rare. As I stated before, any time
Outlook disconnects without properly closing the NK2 file, it may
corrupt. For people who have some problem with their computer (such as
crashing, or Outlook closing) this could be a frequent occurrence. On a
normal, stable machine, I agree that the NK2 file will not typically
corrupt. Since we're dealing with people who are having some problem
with the NK2 file, we should not rule out that it may indeed corrupt
its self.

Actions like opening in Wordpad, or notepad, then saving the file can
also corrupt the double binary structure of the NK2 file. Wordpad and
notepad can not read double binary properly.

Josh Davis

From what I've seen, the connection to the NK2 file becomes corrupt more
easily than the file itself. That's why creating a new profile, then
renaming the NK2 file so the new profile can use it often works. That's the
only way to determine whether the problem is a corrupt profile or corrupt
NK2 file without using a third party utility.

Does NK2info detect and repair a corrupt NK2 file?

I totally agree with you, Mr. Valentine.

As for repairing NK2 file corruption, unfortunately NK2.info will not
physically manipulate the NK2 file. In the case of a corrupted NK2
file, it may still read the e-mail addresses and names associated with
them. The thought is that you would then be able to import this
information into another program -- presumably Outlook.

Of course one could then repopulate a new NK2 file using contacts, with
a little bit of work. I believe you're familiar with the process.

OK. Got it. It sounds like the solution for recovering from a corrupt NK2
file is largely independent of NK2.info, then, since exporting the
information will not provide a method for populating a new NK2 file and
users can already repopulate an NK2 file from their Contact data.

Unfortunately, if the user has some addresses in his or her auto
complete list, they will not be able to repopulate an exact NK2 file
without first getting those addresses into their contacts.

This is where NK2.info comes into play.

After exporting the auto complete addresses to their contacts using
NK2.info, they can then repopulate a new NK2 file using Outlook. The
best method to do this would be to create a new Outlook Address Book,
and import your addresses from NK2.info into this newly created OAB.
Now just repopulate the NK2 file and you're done!

Based on this, NK2.info may prove helpful when a NK2 file becomes
corrupt.

Since most users use the autocompletion cache for their more frequent
recipients, odds are most of those addresses are already in their Contacts
Folder, so they can just repopulate from there.
If they wanted to use NK2 info to bring their autocompletion entries into
Outlook, they would need to import to a Contacts Folder. You can't import
into the OAB. It does not exist.

As I stated above, you should create an Outlook Address Book in your
contacts folder. For instance you might call it "My NK2 imports". Your
"Contacts" folder is an OAB, and you would create this other OAB inside
of your "Contacts".

I have to respectfully disagree with the odds. It's not responsible to
assume that your Auto complete addresses are already in your Contacts,
anyway. The NK2 file caches an incredible amount of Names and E-mail
addresses. The obscure e-mail address you need may be in there -- and
not your Contacts. To prevent this I highly recommend you export your
NK2 addresses, somehow.

Either way will work -- depends on what the user wants, and the risk
they're willing to accept.

It's better to call it a Contacts subfolder. Calling it an Outlook Address
Book will confuse people becasue they will try to import into the Outlook
Address Book, which of course is not possible.
You're probably right about newer Outlook users. Many of them may have built
up an autocompletion cache without ever having populated their Contacts
Folders. Backing up the NK2 file is a good idea for those users. I'm not
sure exporting them to a different file format works as well. It certainly
doesn't for PST files.

Is it possible for someone to suggest how to copy the NK2 folder for a user
of Outlook 2003 who had to go through a data recovery process before
restoring the Outlook files? Something clear and succinct? Would be much
appreciated.

Perhaps this will help: http://www.ingressor.com/autocompletetips.htm .  See
the "Migrating your NK2 file to  a new machine" section.

If the free utility works I'd say use it.  However, you may want to review
our latest release of NK2 File Management software.  The latest release will
actually repair a corrupted NK2 file, that means you get to keep ALL of the
valuable contents including SMTP Name and email addresses, Exchange Gal
references and x500 data, etc.  Check us out at www.ingressor.com  You can
have our software analyze your Nk2 file for errors.

Save the NK2 file.  Then when you create the new mail profile, while outlook
is closed, delete the NK2 file Outlook created anew (if it did) and replace
it with the saved NK2 file, giving it a file name that matches the name of
the new mail profile.  Start Outlook and it should use the renamed NK2 file.
