Hi,

We have an e-mail address for our Support team. All support requests
are sent to that one address and are read by our technicians. The
problem is, the support team is quite large, and it's impossible to
tell which requests have been read, which haven't, which are being
worked on, etc, unless you e-mail everyone on the team to say "Hey,
I'm working on this request!"

Is there a way to make the Inbox a resource, so if Bob marked an
e-mail as read, or flagged it, then Billy would see that reflected on
his computer as well?

Thanks!!

Are you using Exchange?
If so, you can use a shared mailbox and make sure all users have permissions
to access it as a secondary mailbox in their mail profiles, & send as that
address, even. Regarding the read/unread status - that's per user, so I
don't know if you'll see it reflected properly, but you could instruct staff
to move messages to another folder in that mailbox once they've dealt with
them, and also try UniSent from www.ivasoft.biz to keep all sent items in
the same place.

Try posting Exchange questions in microsoft.public.exchange.admin and
mention your version of Exchange.
