Hi Mike:
This is not as serious an issue as it seems. Mail that is sent to your
exchange server will not be returned to sender for some time after it can't
find your server. So while mail would be delayed, you should be able to get
your server back on line before your mail starts bouncing back to the
sender. It would be a rare, catastrophic occurrence that would put you off
line for any extended time.
There are a couple of things you can do to limit your exposure. Use quality
hardware, a great UPS, and have known good backups. If your organization
would be in serious pain without a constant flow of mail, you can have a
duplicate, tested server and images of your system and data partitions ready
to put back on line should the main SBS be non recoverable.
Having said that, if you absolutely, positively cannot be without mail for
even a short time, then perhaps a hosted solution with failover would be
best for your company. You could use "Outlook Anywhere", OWA, or even call
it down to your local desktops with pop3.

So that mean if SBS is down no emails for no one until sbs is up and
running,
so the secondary mail server is just a storage where emails will go when
it
couldn't contact primary mail server and can only be downloaded through
POP3
connector, that means each user account will need to be configured to get
pop3 from mail.secondarymailserver.com??
Also is there any solution where if SBS is down people could still get
as long as there is interet connection?

The information for the temp or backup server resides in the DNS MX
records
you setup with your DNS hosting service. Of course you have to use a mail
server with agreement from whoever owns it (usually your ISP will provide
it
if asked). The POP3 connector is configured by running the CEICW, but
again
you need to be using a mail server which allows for POP3 download when it
is
just storing the mail while your server is down.

Hi Costas
Thank you for the reply. Here is what I need to know: Where do you set
up
secondary mail server details, is it just the matter of entering ip
address
of ISP or more setup on SBS? and how do you configure POP3 connector so
that
the clients would get email even sbs is down?

That, more or less, is the same depending on how you set it up.
You can have a secondary mail server (which can be your ISP's mail
server)
that receives the emails when your server is down. In this scenario,
you
will have to setup the POP3 connector to download the emails after
your
SBS
server goes back online. The advantage to this scenario is that you
can
use
an email program to access the emails (at your ISP or wherever the
secondary
mail server is), while the server is down.
A backup mail server is a temporary storage location where the emails
are
queued when SBS is down. When SBS is down, the backup mail server
knows
to
forward the messages in the queue to the server. The problem with
this
scenario is that you can't use a mail program to read the emails while
in
the queue.
Hope that clarifies it a bit.

What is the difference between secondary mail server and backup mail
server.
What would be appropriate for SBS03, and what are steps to create
one?
Thank you.
