2007 and above (both Outlook and Exchange) will use the free/busy web-service preferentially to look up free/busy info. They do those lookups primarily via e-mail address.
Versions of Outlook and Exchange prior to 2007 treated sub.domain.com as the same as domain.com in some places and as different things in other places. ________________________________ From: Alex Fontana [afontana...@gmail.com] Sent: Wednesday, July 01, 2009 5:43 PM To: MS-Exchange Admin Issues Subject: Free/busy question... Exchange 2007 SP1, OLK 2003, 2007 and OWA Have an availability address space of sub.domain.com<http://sub.domain.com> with an access method of public folder. We have a recipient of type mailUser with an external SMTP address of u...@sub.domain.com<mailto:u...@sub.domain.com>. The free/busy data for this user is perfectly visible from OLK2007 and OWA, but not from OLK2003. Seems I'm missing something here...if the access method is public folder aren't OLK (both versions) and OWA going to \non_ipm_subtree\schedule+ free busy\EX:/O=org/OU=AG/cn=recipients/cn=user.eml for free/busy? This users legacyExchangeDN is /o=org/ou=ag/cn=recipients/cn=user Thanks, alex
