User could not send from another email address belong to himself

post from vpn. reason: can not access wordpress.com from China.
When user mailbox have multi email addresses, for example a@corp1.com and a@corp2.com, primary email address is a@corp1.com. And he wants to send a mail with mail from a@corp2.com. Then he will get a NDR that he does not have permission to send as a@corp2.com.
This is by designed. Do not try to change the behaved.

To help user get what he want, here is a workaround.

1 create a new public mailbox for him.
2 assign full access and send as privilege on the public mailbox for him
3 change primary email address on the public mailbox to a@corp2.com at the meanwhile change his email address to a1@corp2.com
4 ask helpdesk engineer to add the public mailbox opened in his mailbox account from outlook account settings.
