Hi Dick Sevier,
>>because when I start an email in the blank following the "to" panel, several possible email addresses pop up.
Do you mean the auto-complete name cache which pop up when typing the first few letters of an email address or contact name? If this is the case, I'm afraid it cannot prove "The contacts must be there somewhere" as the auto-complete cache is separate
from the contacts.
Do you have the latest version of iCloud for Windows installed? Earlier versions of iCloud have some compatibility issues with Windows 10 which also affects Outlook functionality. Please make sure you installed the latest version of iCloud and then
see whether this issue continues.
Regards,
Steve Fan
