    Is "john.smith@Company portal .com" a valid mailbox within your Office 365 tenant? What does Get-Recipient "john.smith@Company portal .com" show?

    Two thing you need to pay attentions to:
    246239-1.png

    You need to connect to Exchange online module with tenant admin account with have permission to find this mailbox and add permission it:

    Use command below to check whether could find this mailbox first as michev said:

    Get-Mailbox mymail@jitter.com  
    

    Then check whether this account has permission to run Add-MailboxPermission command (Tested with another user mailbox first):

    Add-MailboxPermission -Identity "mymail@jitter.com" -User "anotherUserMailbox" -AccessRights FullAccess

    Anyone know how to supress these errors in Azure Automation runbook ?

    It looks like they are being written to Output window, even if you catch them, out-null them, save them in your own ErrorVariable ... they just keep showing nevertheless as Output stream.
