I get an issue on some users where Certificate error popup pops up, i narrowed down that this only happens to some users using outlook 2010, anyone got any info regarding this or what i need to look at?
We run Exchange 2007
Exchange 2007 self signed smtp cert and havent got a PKI in place
We only use entrust as our Trusted Cert Authority for Webmail SSL, Autodiscover etc,
Software/Hardware used: Exchange 2007, Outlook 2010
