Re: Sending mail to users without Exchange accounts

Yes, I believe it should work for them just fine. When you send a message
to bob@xxxxxxxxxxxxx, Exchange will first look for a local email address.
If it can't find one in AD, it then carries out the "Forward all mail with
unresolved recipients to host box" step and mail is sent to your 3rd party
email hoster. As long as the 3rd party hoster has an account for
bob@xxxxxxxxxxxxx, the message will be stored on the 3rd party hoster's
server.
Now, things may get a bit more complicated if you are using the POP3
Connector to download ALL mail for "ourdomain.com" accounts via a "global"
POP mailbox at your 3rd party hoster. I'm not sure if a "loop" will be set
up. I'm thinking the mail would be downloaded to your Exchange server and
then those messages with no corresponding AD email address would be
forwarded back to your 3rd party email hoster. The next time the POP3
Connector does a download, I'm not sure if the same non-AD messages will
again be downloaded and then returned to the 3rd party hoster. I don't know
if this would cause any problems if the external (non-AD) user is reading or
downloading his mail at the time of a POP3 Connector download.
It may be best not to use a global mailbox for downloading mail for your
Exchange users. Might be better to set up the POP3 Manager to download
individual POP3 account mail just for those users who have AD email
addresses.

Thanks for the quick reply Merv. I have a question after reading the KB
article that may be obvious (sorry if it is). The users we're having the
problem with don't exist in AD either (they are people involved with our
organization, but don't work here and don't use any of our computers).
Will
this solution work for them too? Thanks so much for your time.

We use POP3 mail accounts from our webhost for our organization's
email.
We
use the POP3 Connector to download the emails to Exchange - which works
fine.
We run into a problem sending email to any address ending with
@ourdomain.com if the user does not have a mailbox in Exchange. For
instance, Bob has the email address of bob@xxxxxxxxxxxxx (hosted by our
web
host). Bob doesn't have a mailbox on our Exchange server because he
doesn't
work here in the office. When we try to send an email to him from the
office
we get a 5.1.1 error returned to us stating that, "The email account
does
not
exist at the organization this was sent to. Check the email address,
or
contact the recipient directly to find out the correct address." It's
nice
that Exchange keeps local emails local, but is there a way that it will
only
keep those emails local that have a mailbox?
I'm using SBS 2003 Standard. Thanks for any advice.
