you're supposed to be working with, and the boss may see it as evidence that you're not capable of working out your problems on
your own. Copying both bosses is almost always overkill.
Most email isn't stored locally on your workstation; most of it is stored
elsewhere in your organization, on a server that's maintained by computer worker bees. This has the advantage to you, the user, of not clogging up your own personal hard disk with mail messages. The server's
hard disk gets clogged up instead.
So what's a computer worker bee to do? Simple: Schedule periodic
deletions. Where I used to work, all messages over 30 days old were
deleted once a month. The computer folks usually gave us plenty of
notice, and it was easy enough to save important messages before they
were deleted. Easy, that is, if you didn't have hundreds of messages
from the last two months to sort through. Or if you didn't forget to deal
with them till you were halfway across the country on a trip.
The result of an automatic deletion is that your old email messages --
which have supplemented or replaced your paper chron file -- disappear. That might be great; there might be messages there that you'd
rather have disappear. On the other hand, someday you might want a
copy of the note your boss sent you saying "Don't worry about the Furshlugginer project; it's a low priority right now."
What can you do? A number of things:
Protect yourself: Remember to save copies -- on paper, on your
own workstation, or both -- of your own important email messages.
