for IMAP and POP3 accounts: even if contacts not available within outlook, OL should be able to access Android contacts app.
Sending email to a new receiver first time, is not possible unless email address is copied from contacts app and pasted in OL email. K9 email for Android finds email addresses from contacts app easily.

This worked perfectly for me for years, then it stopped. Multiple times had to re-install and reconfigure Outlook to fix it. Have also reported this via Contact Support option.
