Is there a way to fix this, perhaps running it thru a simple filter

pattern matching right-to-left-of-the-subject-line instead of
right-to-left to avoid issues such as spaces, double etc.

If possible, how do I redirect all messages(incoming & outgoing) thru
this filter prior to the outlook engine?

In addition to what Diane said, keep in mind that your replies are
likely in the Sent Items folder and not your Inbox or whatever folder
contains the message to which you replied (but I'm sure you know that),
so even a "by conversation" view won't show messages that aren't in that
folder. You might consider a search folder that encompasses both your
Inbox and Sent Items folders.

Thanks Diane & Brian. I can see the problem here that the thread
mechanism is using the subject title as the grouping name. And yes, I've
seen the somewhere.

0-) Would it be possible to write a filter/handler prior to
sending/receving email? If possible,

1-) how do I insert it so outlook would re-direct all incoming/outgoing
thru this filter?
2-) is there any simple filter/handler example, e.g. prepend the word
TEST on the subject line (after the if it exist), using simple VBA
scripts or C#.

Thanks,

M.
