We are having an issue with office 2007 crashing. It seems to happen when we upgrade a users PC and use the windows easy transfer that transfers the user NK2 file to the new computer. The user (not all, but about 25%) of users experience outlook crashing when typing an email. We rename the NK2 file to a .old extension (incase we need to access later) and this seems to cure the problem everytime. However, we have some angry users because they have spent 5-10 years building that NK2 file and rely on it heavily. Is there another work around to outlook crashing other than deleting/renaming the Nk2 file? Thanks.

You can try this utility, to either repair the file or move its data to a new file.

Or this one to dump the data out to a PST file and import it into Contacts where it should be.

Most importantly, impress upon your users that spending years to lovingly build up a temporary cache file that is subject to random corruption and data loss is NOT the way to go about it. That is what the Contacts part of Outlook is for. Anyone who loses important data because they were depending on the auto-complete cache to remember things for them deserves what they got.

It seems that this is not an issue with the NK2 file. We are still having users (A LOT OF USERS) experience crashing within outlook and cannot find the cause of it. We have disabled most of the add-ins, tried removing the Nk2 file, and also running /cleanprofile.
