exchange 2010 server
outlook anywhere and autodiscover works from outside the network on windows 7 and outlook 2010, an outlook account can be setup fine.
but on a XP machine with office 2007 I enter the name\email address\password during new account setup and then it constantly asks for credentials connecting to autodiscover.domainname and then 'you must use the mail icon to add an account'
then using the mail icon the error that 'the exchange server is unavailable'
autodiscover.domainname definitely points to the mail server. the ssl certificate works fine internally and obviously on windows 7 externally.
is there a difference between outlook anywhere setup and autodiscover in windows 7\2010 and xp\2007?
