I have a Windows 10 computer running Outlook 2003.
All works fine except when I click [To] button to select the recipient or click Tools from the menu and choose Address book, I get an error. So far I have tried the following:
(1) I ran SCANPST.EXE, repaired Outlook.pst (it found two errors and fixed them), but to no avail.
(2) I created a backup PST file, deleted existing default profile "Outlook" in Control Panel and re-created a new profile "Outlook". Then Outlook created a new pst file "Outlook1.pst". Then I imported backup PST file, but to no avail.
(3) When I run "outlook.exe /safe" and open address book, no error is displayed. But when I open in normal mode, I get an error.
What else can or should I try? This outlook is installed a Stand-alone PC (no network or domain).
