Thank you for reply.

Thanks a lot!

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.

    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.
