Not sure if this happens with 10.0.0 - 10.0.2, or with standard, or with other versions of Outlook.
On three systems, the Outlook address book was missing after the patch. When applying the patch, you should check this or emails sent wont be recorded in ACT!. Easy to fix, but annoying if you miss it.
Would appreciate if other users with standard or different versions of Outlook or XP who have updated to 10.0.2 could check the address book in Outlook and confirm this?
ACT! Preferences still showed the address book... I just clicked on on it in ACT! and it was re-added in Outlook.
