Install Exchange 2007 SP2 on SBS 2008
Currently running through an Exchange Service Pack 2 install for Microsoft's Small Business Server 2008. For ease of reference I thought I'd briefly list the main three steps below:
- Download the Exchange 2007 Service Pack 2 - Exchange 2007 Downloads
- Run through the following KB Article referencing "You cannot install Exchange Server 2007 Service Pack 2 on a Windows Small Business Server 2008-based computer" - KB973862
- Download the Service Pack Installation tool for Small Business Server 2008 - KB974271
*Update*
Service Pack 3 is now available for Exchange 2007 which no longer needs the above steps to install. I believe it is support for SBS 2008 and as per a few we've done already goes on straight away.
Outlook Web Access IIS Redirecting HTTP to HTTPS
One thing I still find with users is that they love to mistype URLs! One common mistake is to enter in the Outlook Web Access URL without specifying the https:// prefix, so here's how we can have http:// automatically redirect to https:// for the OWA directory
Note: this is based on a Small Business Server 2008 install although can apply to any standard Exchange 2007 setup
Step 1) Open up the IIS Console and expand the appropriate Site containing the OWA folder. Select the OWA folder.

Step 2) Open up the Error Pages icon.

You should now see a list of the default error pages

Step 3) On the right side of the window under Actions click Add

Step 4) Create the following custom error page and click Ok
Status Code: 403.4
Select Respond with a 302 redirect
Enter the full HTTPS URL to your OWA location e.g. https://mail.mydomain.com/owa
Step 5) Test the redirect is now working from a client machine
