Autocomplete works sporadically

I am having an issue when addressing and email that outlook sometimes shows the autocomplete drop-down and sometimes not, even for the same contact. I am also having an issue with Outlook not closing properly so when I go to shut down I have to manually end the process. Don't know if it is related. I tried to do a detect and repair but it could not file the file they needed.

1. The problems are not likely related.  Outlook gets its autocomplete lists from Contacts list and from NK2 file. NK2 file may be corrupted.  Close Outlook. Search for and rename *.NK2 file.  When Outlook opens, new NK2 file will be created.

NK2 file is located in C:\Documents and Settings\<user>\Application Data\Microsoft\Outlook folder.  It is a hidden file. It is a hidden file. Go to any folder and select Tools > Folders Options > View. Check "Show hidden files and folders".  Click OK.

2. For Outlook not shutting down, there is a program accessing it.  Disable addins.
