Hi Experts
I am stuck on a problem with outlook sending to wrong internal mail address.

Mail environment is Office 365/Exchange online
On a shared mailbox I deleted a mail alias and added the same mail alias to another user's mailbox.

shared mailbox:
User mailbox:

shared mailbox:
User mailbox: renamed from to

The problem is that when I send an email from outlook 2016 to it is delivered to
But if I send send the email from webmail it is delivered correctly to

And email from my colleague end up in the same wrong mailbox, so the problem is not local to my outlook 2016.
I am thinking that there is something in outlook that is not updating correctly.
