is there a way to 'highlight' or color a message that was sent to me
when I am the blind copy recipient. I don't want to accidentally reply
all when no one knows that I got the message.
Yes and no.
First, just because you aren't on the To or CC line does NOT necessarily
mean you were BCC'd. Exchange Server DLs wouldn't put you on the To/CC line
and neither would any Internet mailing list.
If you want it to be just a hint...
Go to Tools - Organize
Select Using Colors
Click Automatic Formatting
Click Add
Type whatever you want for the Name
Select whatever color/font you want on the Font button
Click Condition
Go to Advanced
Field - Address - CC, Condition Does not Contain: your address
Field - Address - To, Condition Does not Contain: your address
That *should* work. You may need to toy with it a little bit to get it to
work.
