Just upgraded our office install to 2007 and now the out of office
assistant reports unable to contact exchange server, free busy connection
also appears to be down but all else works fine. OWA is fine and works as
normal. Exchange is 2007 64 bit.
Tried a patch from microsoft on the exchange box which was purported to fix
a possible problem with .net but made no difference.
I have also checked office 2010 and this shows the same problem.
Anyone have any ideas, before I go checking my way through all the auto
discovery settings or just rolling back to office 2003 which works fine.
