Proxy access displays wrong number of items in mailbox

When proxying a user the mailbox seems to be empty although it should contain about 180 items.

Removed all proxy rights before running a local gwcheck (Analyze / Fix DB) with the 'proxyminreset' option in the MISC tab twice. Another gwcheck ran on the server with identical options. Reassigned proxy rights afterwards but unfortunately nothing changed.

Anny suggestions welcome.
