Adding POP3 Account to Exchange Users

Thread rating: 
Reda Hanna - 29 Sep 2003 23:59 GMT
We currently have a Small Business Server with 10 User
Accounts. Each user have an internal e-mail
(user@domain.local) and an external POP3
(user@company.com).

I have used the POP3 connector to add the POP3 accounts
so that our SBS server with get the (user@company.com) e-
mail and direct it to the (user@domain.local).

The problem exists with a couple of users who are
sometimes in the office and other times are travelling
away. They need a way to get there POP3
(user@company.com) e-mail to the Outlook 2002 and using
OWA can check any local (user@domain.local) e-mail that
other emloyees might sent them. But the SBS server will
automatically download the e-mails for (user@company.com)
and download it to the Exchange account
(user@domain.local)

Is there a way to keep the e-mails on the ISP server for
a day or two to allow the mobile user to get his e-mail
on his notebook through his Outlook 2002 rather than  
using OWA to check his Inbox.

Configure the smtp connector to leave a copy of messages on server when downloading pop3 mail.

>Configure the smtp connector to leave a copy of messages on server when downloading pop3 mail.

I don't believe this is correct...

If he's refering to the POP3 connector, there's no such
option available... you need a 3rd party product (such as
www.popbeamer.com) to acomplish this.

However, maybe I'm missing something here but why do you
OWA for checking local mail and Outlook for external
mail? Why don't you use OWA for everything... just like
when you are in the office? There are other ways to
acomplish what you want, but since you already setted up
OWA... why do it another way?

My $0.02,

Left a step out sorry....

Don't use pop3 at all, let the smtp service do everything.  Configure the SMTP connector to forward pop3 mail to outside server and configure clients to receive incoming pop3 mail.  Tell your client to leave a copy of downloaded messages on server.  Done, problem solved.

The problem is that the OP is using POP3 to collect their mail - not SMTP.
Any method to send email back out to an ISP mail server is just more pain
than it's worth.  If it were me, I'd set up the laptops to VPN into the
server, then run Outlook over the VPN.  Voila!  Another option would be to
create a second profile in Outlook on the remote users' laptops.  Open up
your SBS to accept incoming IMAP, and configure the second profile to
connect to your server via IMAP.  It works for slow connections by only
downloading message headers, and all email (both external & internal) is
left on Exchange, allowing it to be backed up.

Remember - keep it simple!  ;^)

I agree with Chad...

But, if they already using OWA... then they have everything already running.
I don't think it can get any simpler than that. I'm waiting to see a
compelling reason why not use OWA for both (internal/external mail).

Since the OP indicated that they wanted to get their email 'into Outlook' -
it is possible that they need offline access to the messages, in which case
OWA doesn't cut it.  Otherwise, I agree that OWA is pretty simple  ;^)

Thank you all for the feedback ...

Well ... This is what I am going to do and tell me your
comments ...

1. Back up the user personal folder to a local PST file
on his notebook

2. Delete his mail box on the Exchange Server

3. Open his Outlook and configure it with his 2 different
POP3 email accounts where one is user@company.com and the
other is user@earthlink.net

4. Log off Outlook

5. Add the user Exchange Mail box Account again
user@domain.local

6. Go to the User Control Panel, and under Mail, I
connect him to the Exchange Server.

The problem with the above solution is that the local
mail will be delivered to his Local PST file whenever his
is connected to the company's network whereas the OWA
will be limited in terms of usability from outside of the
company except for checking the Public Folders ...

Please advice if this idea is OK or if you have other
comments.

I am having a similar problem.  On my clients laptop we have Outlook
configured to get exchange mail using the pop3.  This use to be working
until recently.  We have the option on the clients Outlook, checked to leave
a copy of the message on the server.  This allowed my user to receive email
using the SMTP on his work workstation and then also receive the same
messages on his laptop when at home.  This was working until I applied the
recent post sp3 update.  Now I get the message, "Report error 0x80042104
'Your email server does not have the features required to allow messages to
be left on the server'"  Does anyone know how to help?

Chad - They are not sending email "back out" to an smtp server, it's being forwarded the first time they send it; I'm not sure how you are arriving at this conclusion unless you are refering to the remote users, who should be using their isp's smtp server.  Setting up vpn access is much more tedious than configuring the smtp connector (provided that they even have or want a vpn for that matter).  Not to mention that mapi can be very slow at times across a vpn.

Reda - All you need to do is configure smtp to forward to a smart host.  From system manager, go to the properties of your default smtp virtual server, then delivery/advanced.  Enter a smart host for your outbound pop3 mail (email.company.com).  Configure outlook clients to retreive the pop3 mail and leave a copy of downloaded messages.  Your remote users should be configuring outlook to use their isp's smtp server while abroad.  This solution works flawlessly if done right.  Easier than setting up a vpn I think and faster too.  Chad's solution could be used as well; a vpn is a viable solution if you had to go that way.

Good luck!

Hi John -

I've re-read this thread, and I'm obviously missing something here.  We're
all here to learn, and we know that there's more than one way to skin a cat,
so I'm hoping that you can clarify this for me.  I can identify where I'm
lost:

I'll gladly admit that I don't see exactly what you're suggesting here,
specifically in regard to configuring the SMTP connector to forward pop3
mail to the outside server.  I follow your suggestion to drop the POP3
connector and just use SMTP (thus hosting their own mail).  After that, I'm
just not connecting the dots.  What pop3 mail are we forwarding after we
stop using pop3?  What outside server are you referring to?  (Because once
they switch to pure SMTP mail, their email is no longer stored on any server
besides their SBS).  In which case, the remote users would need to connect
to their SBS to retrieve their mail.  Is that the method you are
recommending?  If so, my only comment is that depending on the tech level of
the users (and their tendency to 'play') - if the 'leave messages on server'
option is deselected, all of the email from their exchange mailbox will be
downloaded to the local pst.  In addition, we haven't dealt with what to do
when these remote users are back in the office and connected to the LAN.
Are we still going to have Outlook pop-ing the server?  Or are we going to
have two separate Outlook profiles (1 for POP / 1 for Exchange)?

Like I said, I'm just not following your recommendation - so hopefully you
can clear this up for me.

John... there's something here that's not clear.

ISP POP3 servers <- SBS servers download POP3 mail from them.
If you set up to the SBS server to forward again to the outside you will end
up on the same cycle.

Even if you weren't using POP3... then with SMTP the mx record for the
domain will be pointing to same SBS server so you can't forward to another
server because it will eventually come back (the smarthost idea). The only
way to do what you are mentioning is using another domain to forward mail
to... but that's something totally different.
