Thanks Diane. Reason for asking this is that whilst pop3 mobile Outlook obviously isn't synchronized.
That is my decision of course, I know. But still wanting the sent items in my Outlook 2016 I want to bcc
to myself.
Found another Android mail app that can do that.
Now I still need to puzzle out a rule that automatically moves those bcc copy Android mails from my inbox
to my sent item box.
Whilst the Outlook for Android app looks nice, I am the last one to argue about that, this bcc thing is important,
so I removed Outlook.
