Windows 7: Outlook 2010 auto complete problems

I can't get Outlook 2010 auto complete e-mail addresses to remain from session to session. Auto complete is removed every time I start Outlook again. I can put them in every session by dragging all my contacts to the inbox and pressing control + K to initiate auto complete for all my addresses, but once I close down Outlook and restart again they are not there and I have to physically type the address in which is becoming a bit of a drag. As you can see from the following image I have auto complete selected.

Any help would be appreciated.

For the benefit of anybody else who has this problem I was having trouble getting the auto complete e-mail list to remain after the current session. I had used a program called PC tuneup and it obviously emptied my auto complete list and my usual method of dragging all my contacts to the inbox and pressing control K would only work for the current session. In other words when I closed outlook and reopened it the auto complete list was empty. I ended up downloading a little app called nk2view and it works really well, not to mention that it made adding e-mail addresses to the auto complete list very easy.

This came to rescue:

NK2View - View Outlook .NK2 AutoComplete Information

Now i can see all the suggested contacts in my regular contacts! Thanks a lot!

I guess the lesson here is not to use programs such as PCtuneUp with Win 7 unless one understands all of the ramifications inherent in doing so.

I actually had the problem recur and using NK2View wouldn't work the second time but I eliminated PC tuneup as the culprit as I hadn't run it a second time. I then downloaded NK2Edit and that rectified the problem. It was brought to my attention that I had corrupted the primary .PST file, emptying the "Suggested Contacts" folder. I did run scanpst.exe located in (c:\Program Files\Microsoft Office\Office14), several errors were found, repaired and this time the problem hasn't recurred. So it is probable that using NK2edit and scanpst.exe both work.
