Thanks. We'll let you know when a new response is added.

The first thing you need to consider is that this upgrade can’t be done <i>in-place</i>.

You will need a second machine to do the upgrade.

- If you want to be really cool you can go copy the N2K file from your users computers so on the new setup they will have all their Autofills and such. The N2K is located in User/Appdata/Roaming/Microsoft/Outlook/Outlook.N2K
