In outlook the auto complete gets stored in *.NK2
. Where does it store for OWA 2013 ?
Some people saying that it gets stored on exchange server within user email account. Is there
a way that I can make a copy of this file and put it back when users somehow lost their auto
complete address list? Some of our users are going crazy about losing their email address
cache. All they did was reset IE 10 and the OWA email address cache all gone. which means that
auto complete list is not stored on exchange server under user account?

The auto-complete data is stored directly on the users mailbox database (since exchange 2010).
I had the same problem with a single mailbox. I ended up having to migrate the entire user to a new mailbox (deleted and restored). However this is only on rare occasions.
Few things you can do that usually fix this.
Make sure that works by restarting the outlook client and seeing if it fixed the problem.
If that didn't work your best bet is to initiate a complete mailbox export request via exchange powershell and delete the account. Recreate immediately and re-import data you exported.
Note: When you do this, it will cause everyone's auto-complete for that user you recreated to not work until they re-add the user from the address book or delete that user from auto-complete (price you pay).
