Moving users to different subscription - effects on current mailbox?

Good afternoon, all!

We have an interesting wrinkle on a new subsidiary of one of our customers. There's a user who wants a mailbox for people they expect mail from, such as customers, employees, and other known contacts. They also want a mailbox essentially as a "honeypot," to catch unsolicited mail from people who figure out the naming convention and start sending spam. The "good" mailbox has an O365 E5 and Mobility E3 license assigned and the "honeypot" just has an Exchange Online Plan 1 assigned.

We found out that the licenses for these two need to be swapped. Is there a way to do this behind the scenes and not affect the mailboxes? The mail address won't change, so I think this can be done according to this article, but I need to check and be sure. In any event, I'll probably back up the user's mail on their laptop anyway.

Thanks to all for looking!

Gregg

    Yes, that will work, but why not simply convert the honeypot mailbox to a shared mailbox, give full access to whomever needs and not use license at all for it?

    The licenses are only required for the user mailboxes accessing the shared mailbox.
    You can send as a shared mailbox and the shared mailbox does not need to be licensed as long as its below 50GB :)
