The Bat always downloaded my mail automatically when I turned on PC, as it was set. Suddenly you will not download more and you will see a table where it is written: "The server did not provide the root certificate during the session, and no the root certificate appears in your address book. This connection may not be safe. Please contact us your server administrator. Continue anyway? " My OK is the discharge. What should I do to get back to automatic mail unloading?
