How to Display SCL (Spam Confidence Level) in Outlook 2007

Firstly, download and install this Exchange Event Sink as described here:

Secondly, create a custom formula field to display the SCL as described here:

The use of Right([Comments],5,2) allows an SCL of -1 through 9 to display correctly.

Of course, if you are using Outlook 2007 with Exchange 2007 you can see the Spam score by looking at the Internet headers - I have not seen a method to display this on the Outlook email list page yet.

Downgrade Exchange 2007 B2 to Exchange 2003 SP2

Oh, what fun and games I had.

First I backed up all the mail:

• Outlook export to PST
• ExMerge (Hey - It worked on Exchange 2007!)
• NT Backup of store

Then I removed Exchange 2007 and reininstalled Exchange 2003 - Except it didn't quite go that smooth,

The installation errored saying that it could not install the information store and to check the install log. I found this error message:
mode = 'Install' (61953) CBaseAtom::ScSetup (f:\titanium\admin\src\udog\setupbase\basecomp\baseatom.cxx:842)
Error code 0XC00736B1 (14001): This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem.

Tracing back up the install log found this message:
Interpreting line -- ID:31259 --
CInsParser::ScProcessLine (f:\titanium\admin\src\libs\exsetup\hiddenw1.cxx:1225)
Error code 0XC00736B1 (14001): This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem.

Tracing back futher led to this line:
Copying c:\program files\common files\microsoft shared\cdo\cdoex.dll
Preserving existing copy of c:\program files\common files\microsoft shared\cdo\cdoex.dll
Sure enough, typing "regsvr32 c:\program files\common files\microsoft shared\cdo\cdoex.dll" produced the same error code.

I deleted the copy of cdoex.dll and replaced it with the copy from the Exchange Server 2003 CD and re-ran the regsvr32 command - It worked. I clicked "Retry" and the install completed.

I did receive an error message about the wrong version of mapi32.dll being on the hard disk so I also replaced from the CD too.

Applied Exchange 2003 SP2 and visited Microsoft update to apply some hot fixes and everything appears to be working well.

Blog Outage

Sorry for the outage - I needed to remove Exchange Server 2007 B2 from my test server and return to Exchange 2003 SP2.  This did not go smoothly and I had to do a lot of troubleshooting.
Part of this troubleshooting involved removing IIS (and all the wen sites with it) which brole ASP.NET 2.0 and everthing that relied on it.
Everything is installed and working again (except my ISP connection is down).
Everything should be back to normal.
