The From picker offers the member's primary mailbox again on each org alias domain, with an id like <mailbox>:alias-domain:<domain> to keep it unique in the list. The client sent that id back as a mailboxId when a non-default alias domain was picked, and the send or draft failed with a 400 parsing it as a UUID. The row now says aliasDomain: true and carries mailboxId, the real mailbox, so the client can tell it apart.
