I have my inbox set up to apply different colors to incoming email based on
the "From" field. Some of my filters have stopped working and I cannot get
them to
function anymore. I have not made any changes to any of the rules. I've
tried to restate the rules and add new ones without success. Some of my
filters are still functioning properly.

All of the filters still function properly on my other mail folders (which I
use to organize old messages). Just not my inbox. If I transfer an
uncolored message from my inbox to one of my organizational folder, sometimes
the message turns the approriate color. If I tranfer a still colored messge
some time the color turns off.

While the Organize pane is open, I have clicked the Automatic Formatting
link at the
top right and examined the individual rules carefully and see if I could
figure out the problem that way. Some of the rules don't work anymore and
some do.

An example of a rule that doesn't work any more is:
Properties of Selected Rule = font is green

Advanced Condition:
Field = From
Condition = contains
Value = (E-Mail Removed)

An example of a rule that still works is:
Properties of Selected Rule = font is pink

Advanced Condition:
Field = From
Condition = contains
Value = (E-Mail Removed)

I am using Outlook Professional 2003. Each of the rules (both wokring and
non working) have around 50 simple one line rules like the above. (basically
50 unique senders).

The problem started concurrently with my .pst file reaching almost 1.9 GB.
I split my mail folders into new .pst files and compacted them so they are
each now, about 800 MB. Could this have corrupted my rules somehow?

I live and breath by my colored e-mails. Any help would be most appreciated.

Does anyone have any insight on this problem?
