Seen Flag problem and kolab sam question

[Philipp Weber]

Hello,

i have the following problem.

The clients are working with Thunderbird and Roundcubemail together in a
shared mailfolder but the seen flag isnt working.

The big problem is they all working on incoming new mails.

Where can be my problem?

$> kolab lam shared/***@ddomain.de
Folder shared/***@domain.de
lrswipkxtecdn anyone

Follow up question:

When i do
$> kolab sam shared/***@domain.de anyone full

Is it automaticly recursive?

Thanks mates
