Just to make sure I got you right:

The shared mailbox has been migrated to dovecot correctly.  I call it
'sharedbox' for now.

The user's mail has also been migrated correctly.  Let's call her/him
'user'.

Then I would run

  doveadm sync -1 -u user -m shared.sharedbox imapc:

to sync the flags for user 'user'.  Correct?

Makes sense.

We have individual flags for shared mailboxes now and configured dovecot
accordingly (see dovecot -n output attached).

Thanks so far!  I hope this will work!
