Is the WRONG Message sent if club officer alias rejected

According to support.toastmastersclubs.org/doc/item/email-lists-and-aliases written by Jane Atkinson, it states that Individual Club Officers aliases are "publicly accessible. Anyone can send an email to these email addresses, but each one can be disabled by the respective officer in their member profile."
First, what is the message returned if the respective officer disabled their alias in their profile?
(I never thought to test it before now.)

Second, I've been getting the following message lately from FreeToastHost Server <server@toastmastersclubs.org>, .
"You do not have the right permissions to send an e-mail to this e-mail address (vpe-681947@toastmastersclubs.org) from paneldiscussion1645@outlook.com . Be sure your "From" address in your e-mail client is the same as your address in your toastmastersclubs.org member profile."
This contradicts Jane Atkinson's definition on who can send messages to officers through this alias. OR is the wrong message being tagged (indexed)? .

paneldiscussion1645@outlook.com is a brand-new, project specific Outlook email account. Messages have been successfully sent from it to VPE, VPPR, VPM at various other clubs, though most haven't been answered yet. For some reason, only one vpe-681947@toastmastersclubs.org seems to get the above error message.

Is there anything wrong with using Officer Alias in the following ways?
1) Placing VPM, VPPR, or VPE aliases in press releases, flyers, events, etc.
2) Using club officer aliases as owners of accounts for seamless transfer on July 1? (For example, opening an Eventbrite account using the VPPR alias as owner, so the current VPPR can not only get notifications of new signups but also access reports through their private accounts. Opening or transferring a Free MailChimp account to VPM ownership, since the VPM logically would be accessing the database and composing messages to registered guests? Maybe also assigning Social Media (Facebook,; Linkedin) accounts as well to VPPR, unless one or both have separate administrators.)
