Exchange 2003 and Outlook 2003 introduced a unique method for
accessing Exchange server from both sides of the firewall
securely without a VPN. RPC over HTTPS in Exchange 2007 and
Outlook 2007 is now called simply Outlook Anywhere. Rather than
opening up several RPC ports, RPC is tunneled through HTTP. With
SSL, only port 443 needs to be available for Outlook Anywhere to
work outside of the firewall. Outlook Anywhere requires Outlook
2007 or Outlook 2003 installed on Windows XP SP2 or Windows
Server 2003. Outlook 2003 clients can use Outlook Anywhere as
they did RPC over HTTPS, but they cannot take advantage of the
Autodiscover Service and will need to be configured manually.

The calendar in Outlook Web Access 2007 does not include a month
view. Microsoft hopes to bring a month view back in a later version,
but for now, its day, work week, and week views only. Additionally,
these views are available only in the premium OWA client which is
available in Internet Explorer. The OWA "light" client, which
displays in all other browsers, offers a day view only.
The good news is that Exchange 2007 SP1 is the "future version" and
contains a month view in the premium version while the light version
continues to have a day view only.
IE6+ on Windows is the only supported version for OWA Premium
because of the cost, time constraints, and customer needs. A small
percentage of users use something other than IE6 or greater on
Windows and an even smaller percentage of this group need to access
an Exchange server. At this time the cost to tweak the advanced AJAX
behaviors used by OWA for this small group with is better spent on
improving other aspects of OWA (including adding new features).
Exchange Server 2007 Service Pack 1 Beta 2 was released to MSDN
and TechNet Plus subscribers last week. I can honestly say I'm
impressed with the features in this SP.
I've always felt that upgrading to Exchange 2007 RTM was not an
option for smaller sites because the Exchange Management Console
lacked a GUI to configure many frequently used settings. That's
not going to be an excuse much longer. SP1 adds a GUI for
configuration many common options, including public folders, POP
and IMAP access. A wizard guides you through setting SendAs
permissions.
OWA gets back a lot of features left out of Exchange 2007 RTM
due to time constraints. This includes personal distribution
lists, S/MIME, rules, the monthly calendar view, deleted items
recovery, and public folder access.
Among the other improvements in SP1, you can install the
management tools on Windows Vista and Windows Server 2008 and
the Move Mailbox administrator tool can import and export to a
.pst
Standby Continuous Replication (SCR) is new feature providing
high-availability to organizations, allowing them to quickly
recover from failures. Mailbox data is continuously replicated
to a standby server using the built-in log file shipping
technology so that if the primary server goes down, the standby
server is ready to be activated.
