Have a 2008 SBS server with XP, Vista and 7 computers all patched simple network setup. One user on the network when opening outlook 2010 is prompted by a security alert stating that the ceritficate name is invalid. 2003 and 2007 outlook users do not get this error. I do not know if the other 2010 user gets this message but have heard no complaints. We have a go daddy cert on the server. When i view the cert on the problem machine the cert does not match the go daddy cert we are supposedly using. How do I fix this without breaking for rest of users? This is a clean load of win7 pro and office 2010 by the way.
