Thanks for shared image!

Please run command.

Add-MailboxPermission -Identity "info" -User "C mailbox" -AccessRights FullAccess

And than OWA retry!

    Hello! Dracarys0507​ 

    Here's how to do it!

    1. Exit Outlook
    2. Delete Autodiscover.xml
    <Path> C:\Users\<username>\AppData\Local\Microsoft\Outlook\
    3. Start Outlook

    Hi

    Thank you. I tried it but it is same. it is just AutoMapping when start Outlook so i can see same pop up of credential in advanced. If it is correct. not pop up of credential like A mailbox. Just B mailbox not added and pop up Windows credential.

    Please run command.

    Remove-MailboxPermission -Identity "info" -User "C mailbox" -AccessRights FullAccess
    Add-MailboxPermission -Identity "info" -User "C mailbox" -AccessRights FullAccess -AutoMapping:$true

    And than Outlook retry.
