You don’t mention Public Folders, and while Microsoft
tried to sweep them under the rug in Ex2007, they’re still needed for Mac
users. If you haven’t set those up, that could be why the Free/Busy
info isn’t returning anything for the Mac users because Entourage still
uses them to store FB info as well as download the GAL.

Subject: [MSUNAG] Strange Exchange issues
We’ve been tangling with Exchange
lately and I wanted to throw this out there in case anyone on the list had any
ideas. Thanks in advance for any advice or pitying glances you can throw my
way.
Client environment is AD domain with Office 2007 and 2008 deployed. Server is
Exchange 2007 SP1. Primary email addresses are firstname.lastname@domain, but
logon is [log in to unmask] PC users cannot see certain Mac users’
calendars / free-busy information.
When a PC user looks at free/busy information, the availability service returns
an error. Other Mac users can be seen by the PC users. The commonality between
these users is that the Mac users that can be seen have used Outlook on a PC in
the past. Additionally, Exchange isn’t creating legacy free/busy mailboxes
for users that haven’t logged on through Outlook, even though I was under
the impression that the free/busy service was supposed to crawl calendar data
and create those automatically for legacy use. (to provide legacy compatibility
with calendar entries made on OWA / Entourage) PC users can see Mac calendars
when in Online mode, but still can’t see free/busy information unless
that Mac user logs in with Outlook on a PC to create a legacy free/busy
mailbox. Once the legacy mailbox is created, the Availability Service returns
the proper free busy information.
Questions: why does a legacy free/busy mailbox need to exist for proper
Availability Service functionality; why can PC users only see Mac calendars in
Online mode, not in Cached; does the free/busy service on the Exchange server
only update legacy mailboxes or can it be used to create them for Mac / OWA
clients.
From reading the Microsoft documentation it looks like everything is set up as
it’s supposed to be, which is where I hit the wall.
Thanks,
