Today I had the joy of someone with a local profile logging on and windows gave them a new one thinking the old one was corrupt.

the only thing the user complained about was the fact when they typed "ad" in to the name box in outlook none of their past user names that they had emailed came up.

After having a quick look around I found this

its extremely simple to do and will save you a lot of headache with the users!!

simply copy the *.nk2 file from %userprofile%\application data\Microsoft\outlook\

You need to close outlook first to move this to the newest profile.

Once copied in you don’t need to do anything else apart from accept the thanks... yeah right like the users would thank you!!


***EDIT***

I've also just found a program called NK2View which works very well you can view edit and delete names from the auto complete file. See info HERE and download HERE
