Question

Hi all,
I tried following the document: https://learn.microsoft.com/en-us/exchange/client-developer/legacy-protocols/how-to-authenticate-an-imap-pop-smtp-application-by-using-oauth but unable to get through this step: https://learn.microsoft.com/en-us/exchange/client-developer/legacy-protocols/how-to-authenticate-an-imap-pop-smtp-application-by-using-oauth#register-service-principals-in-exchange.

When following : Register service principals in Exchange

I trying to execute below command :

Add-MailboxPermission -Identity "john.smith@contoso.com" -User 

Answer 1

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

Answer 2

@Vinay Sharma

Two thing you need to pay attentions to:

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.
