Change Addressbook Column width in Outlook 2000

To adjust the column width, follow these steps:
 

• Click Start and click Run.
• In the Open box, type regedit, and then click OK.
• In the Registry Editor navigate to the following key:
• HKEY_CURRENT_USER\Software\Microsoft\Exchange\Client\Options
• With the Options subkey selected, on the Edit menu, point to New, and then click DWORD Value.
• For the name, type AddressBookColWidth, and then press ENTER.
• Double-click AddressBookColWidth, and in the Value data box, type the width you want. You may have to change this setting until you arrive at the number that best suits your needs. A recommended starting point is 79.
• Click OK to save your entry.

 
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.
