        Hi,
aha, I see. Thus the Search field has set (when you click the magnifier
icon on the left) "Subject or Addresses contain", eventually only
"Subject contains" option, which is also shown grayed in the Search,
when nothing is filled there.

Such searches are not done on the server, because all of Subject, To
and CC headers are cached in the local cache. The server-side search is
done only/mainly for the body/message contains search type.

Doing a search in a folder which is not selected in the UI (aka in
"Current Folder and Subfolders" or "Current Account" or "All Accounts")
doesn't invoke refresh of the folders, it just reads what is cached
locally. Such refresh may take quite long time (especially when the
folder has many new messages, which means to fill the local cache (the
folders.db file)).

You've an option to check for new messages in all folders (especially
when multiple clients are accessing the folders), which is in account
Properties->Receiving Options tab, or selectively in folder Properties
(in a context menu above the folder in the folder tree on the left of
the Mail view).

        Bye,
