Dear all,
In my organization, I have exchange online and crm dynamics 2015.
I have email router to handle email for CRM dynamics. I have created a shared email "AdviserMasud@myorganization.com", I have mailbox called "AdviserMasud", I have queue name "AdviserMasud". In the queue I am using advisermasud@myorganization.com as the incoming email address.
When I go to my mailbox-->click Approve Email and Test Enable Mailbox, it does not work and give me error message:
Email won't be processed for this mailbox until the email address of the mailbox is approved by an Office 365 administrator. For more information, contact your system administrator.
This mailbox is disabled for email processing. For more information, see the alerts.
My manager is office administrator and he has approved and tried test and enable mailbox and still getting the same error messages.
Here is the user administrator settings related to email:

So, I would like to know
1. What am I doing wrong?
2. How can I enable mailbox for email processing?
Many thanks in advance.
