Outlook 2007 .NK2 file

[Mike]

What is the limit for the Outlook 2007 Auto-Complete file (.nk2). I have seen
conflicting reports on blogs that the limit for the .NK2 file for Outlook
2003 & 2007 is 1000 addresses and then I've seen it is 1000 for 2003 and 2000
for 2007. I have a technician with a user with Outlook 2007 that has over 900
but I don't believe he has broken the 1000 mark. The issue is new addresses
are saved to auto-complete list but old ones are missing. Any ideas to the
cause of this would be appreciated.

Has nothing to do with the limits (1000 for OL 2002 and 2003, 2000 for OL
2007 and 2010). The feature is not reliable. Outlook frequently loses its
connection to an NK2 file whenever it doesn't close properly. More
