Set mail_debug=yes. What does it log when 1) logging in and 2) when it
creates the %% directory (or is that also on login)?

prefix = shared.%u.

Although this won't work well because your username most likely has '.'

'/', but that can then cause problems with existing clients that use
your system (possibly requiring some kind of client cache refresh /
account recreation).
