Adding multiple mailboxes by adding a single email address in outlook

Question

Before I begin , I want to apologize for asking such a childish question.

I saw yesterday user that had 4 mailboxes in his outlook. Whereas I saw only 1 account and 1 .pst file attached to outlook. So, my question is that is there a way to add multiple mailboxes just by adding one email address to outlook. For e.g. I have added [email protected], but it should automatically install [email protected], [email protected] and [email protected] as soon as I install [email protected] to my outlook.

Is this something I have to do on the M365 admin portal?

Please assist.

In outlook side, firstly, you should add the [email protected] account then add [email protected], [email protected] and [email protected] one by one via 'Add Account' button manually. Once you done this, restart outlook, then choose the profile you have configured just now, you can see theses three accounts appear in outlook at the same time. If you done it in this way, it is not a smart way, you always need to manually add these accounts manually in other PC when you want to login in [email protected] account and wants [email protected], [email protected] and [email protected] to be kept.

If you are exchange administrator, you could follow below guidance to make these [email protected], [email protected] and [email protected] automapping to the primary account [email protected].

Add-MailboxPermission -Identity [email protected] -User [email protected] -AccessRights FullAccess -AutoMapping $true

Add-MailboxPermission -Identity [email protected] -User [email protected] -AccessRights FullAccess -AutoMapping $true

Add-MailboxPermission -Identity [email protected] -User [email protected] -AccessRights FullAccess -AutoMapping $true

Full Access permision allows the delegate to open the mailbox, and view, add and remove the contents of the mailbox and the mailbox auto-mapping feature uses Autodiscover to automatically open the mailbox in the delegate's Outlook profile.
