We've just completed an exchange migration which finished today, but the SSL certificate also expired today. Users are receiving a prompt referring to the old exchange server, which if they are on 2010 should not be accessing public folder replicas from that box.
I've checked all databases to see if the default public folder database is correct. Some users who in the connection status dialogue show the correct server, still receive the SSL prompt.
Is there something I could have missed, short of getting rid of 2007 completely?
