Retention policy apllies to mailbox but didnot works

Good Day.

It is a very strange situation.

1. I`ve created retention policy tag "Move to deleted from Inbox 7" - move to Deleted 7 days old mails

2. I`ve created retention policy with this tag (1) "test" and apllied it to test mailbox

3. Started Start-ManagedFolderAssistant

In Outlook 2010 i`ve connected this test mailbox, when i am looking in Inbox-Folder-Policy i see that "Move to delted from Inbox 7" tag applies to folder, but it didnot works  because in my Inbox folder there are mails older than 7 days...

So what can i do to make this policy works?

Thank you.
