No, it's not expected, and I haven't seen it before -- sorry for the
unhelpful reply! I just tried it (dovecot imap server), and it worked
both with and without angle brackets on the ID (sometimes brackets can
be an issue).

To be sure everyone's on the same page, how exactly are you searching?
If you're in the *Group* buffer and you hit "G G" on the group, and
paste in the message ID, is the message found? If you're already in the
*Summary* buffer, there isn't really any way to "search" as such,
there's only "limiting" what messages are shown by some criteria -- in
those cases it's true you won't be able to get to unseen messages.

But that should never affect following links from org mode...
