Microsoft Outlook 2003 and Microsoft Outlook 2007 do not store email addresses you correspond to via email in your address book, what it does, it stores all these email addresses in what is called the cached file called N2K file. The N2K file cannot be read via a regular text editor nor can it be directly imported into outlook contacts.
Many users get bumped when they find this out, (especially noticeable when they receive a new computer).
The utility we have can open up the N2K file and export all the addresses into a CSV file. Best of all, it is free. 🙂
the N2K file can be located at the following path C:\Documents and Settings\(Your USERNAME)\Application Data\Microsoft\Outlook\Outlook.NK2
Download the N2K tool.
If you have similar tools or cool tools please share it with us…. we will credit you for it
Attached is a utility that would extract the nk2 files into csv (so they can be imported into address book)
Once in a CSV, you can easily delete invalid exchange addresses and maintain the smtp addresses.
Please let me know if you have any questions.
it is a beta version but has always worked for me. 😉
