How do I associate POP3 accounts with Exchange Calendar Info

[jstrummer]

We have installed Exchange 2003 for the calendar sharing. But, for
now, we need to retain our pop3 email accounts that are handled by an
outside ISP.

Is there a way to associate each user's Calendar (shared through
Exchange 2003) with their pop3 email account?

Right now, when a user uses the Meeting Request feature, they can see
other staff members' Free/Busy information, but when they send the
meeting request, it's routed through Exchange's domain.local. We need
to have the meeting request routed through our POP3 account for now.

Is there a way to tell either Exchange or the Outlook client that the
user's Calendar should be associated with a particular POP3 email
address?

Thanks!

No, you can't associate a pop account with the calendar. properly
configured, it's not necessary.

exchange also.

We tried to set up Exchange as you suggest, but the problem was that it
appeared that email sent from people within the domain to people in the
domain was never sent to the POP3 server run by the ISP. This creates
problems because various employees need remote webmail access provided
by the ISP.

Am I correct about how Exchange handles "internal" email, or is there a
way to make Exchange send the email to the POP3 server. Thanks!
