To adjust the column width, follow these steps:
Leave the Registry Editor open and switch to Outlook. Open the Address Book and see if the column width is acceptable.
If not, close the Address Book, leave Outlook running, and switch back to the Registry Editor to adjust the DWORD Value until you arrive at the column width you want.
As you make adjustments all column widths in the Address Book are adjusted. If the value is too large, such as 1025, you may notice some of the right-most columns disappear.
