Looking at the MS Outlook View menu and then Arrange by sub menu, you can see an option to arrange by "Conversation". This begs the question: is it even possible to have a conversation by email? I mean how many times have you put something in an email only later to discover that you were misunderstood?
Omar Khayyam, writing 1,000 years ago, seemed well aware of the perils of the ill-considered e-mail:
The moving finger writes; and, having writ
Moves on: nor all thy piety nor wit
Shall lure it back to cancel half a line,
Nor all thy tears wash out a word of it.
Most conversations are better off conducted over the phone or in person.
It seems we are not the first to discover this....
