Hi Team,
I am trying to setup mailbox sharing. But although user test2 shares
INBOX with test1, it is not visible for user1.

you've marked this as list = no, when it shoukld be list = children. Maybe it'll help.

Is there anything obviously wrong in the config?
I suspect a mismatch between %u and %n somewhere but don't know how to
figure out the culprit.
How can I get more relevant debug log output about namespaces / mailbox
sharing?
Or can I run commands to check validity?

I have updated the conf with list = children.
Unfortunately it did not change anything.
