Search for mails in iCloud does not work

When I type a name or mailaddress in the lookup-box no results are returned for mails in my iCloud.com-account. Nothing, no results at all…

Sending and receiving mails with iCloud.com is no problem…

Why does look-up not work with iCloud.com?

Thanks for your reply but your suggestions do not solve the problem…

Check that you have “All Folders” selected and that you select "Subject, Sender, Receipients, Body, Notes and Attachments in search dropdown as in the V10 example below.

That works for me in my iCloud acct

If that still doesnt find anything, try “unchecking Use Server Search if available” and try again.
