I've been playing around with the Add-MailboxPermission command, and now I want to see what mailboxes I have given myself or another user full access to.
I tried "Get-MailboxPermission -Identity <Mailbox ID 1> | Select User, AccessRights, Deny" and "Get-MailboxPermission -Identity <Mailbox ID 1> | Select User, AccessRights, Deny," however, these do not give me the information I want.
I want to know what users have access to what user's mailbox.
