duplication of forwarded email



let me see which paint and brush I should use : - )

Sorry to reply after so long was on leave but my problem still persists and
so i will keep digging.

There is no forwarding set on his private mail (that would be via MS
Outlook). All forwarding has been set via the ADUC mmc on Exchange.

Just to recap the observed phenomenon:

1. My boss travels a lot and because we dont have OWA for users external to
our network, he uses a public email service (let not worry about whether its
yahoo blackerry gmail hotmail etc as they all behave the same and it means
the issue at hand is not related to the public email service).

2. I have created a contact for his public email service in my AD and set
forwarding of his mail to this account in Exchange.

3. I have selected to keep a copy of on the server so that when he comes
back he see all the mail in his Outlook.

4. What is strange is that he see multiple copies of mail that is forwarded
to him in his public email account.

5. The only exception to this case being when I, or anyone whose mailbox is
on the same Exchange server as him, sends him mail.

6. Otherwise all external mail and mail from other interal users, whose
mailboxes are resident on different servers to his, will generate multiple
copies of the same email in his forwarding email account.

7. I have the latest service pack SP2 for Exchange 2k3 on all the Exchange
servers as well as the latest OS service pack for Win2k3.

8. What I observed when analysing the Internet headers on his forwarded
emails is that it seems when an email is sent to him from say an external
user:

i) the front end server immediately sends a copy to his forwarding
email address
ii) The front end server at the same time sends a copy of the email
to his inbox on his home server.
iii) His home server then also sends a copy of this message to his
forwarding address as per the configuration set on his mailbox.
iv) In some cases a third copy is also sent to his forwarding address
but I cant figure out where it will be coming from and I havent concretely
determined under what cicumstances this occurs.


My questions are:

1. Which server should act on the configured setting of forwarding email as
per the mailbox setting of "Forward email to this address and keep a copy
locally". Is it the front end server or his home server?

2. If its the front end server how does it tell his home server that its
already forwarded a copy and the home server shouldnt worry about doing
something thats already been done?

3. If its the home server that should send a copy how do I stop the frontend
server from being "nosey " and carrying out a function it shouldnt?

Long email I know. I need help and would really appreciate your assistance.

Thanking you in advance,

Mac D

Color me confused, Mac.

Let's start at the beginning - does your boss have forwarding rules set up
on both his private email and in Exchange? If so, that's definitely
problematic.

Hie Missy,

Maybe I shouldnt mention the Blackberry aspect as it may seem its an issue
associated with that. The multiple copies are generated for all forwarded
emails. I setup forwarding to my yahoo account and its doing the same
thing.
My CIO has forwardinf to another email accoutn outside our organisation
and
it does the same thing.

Looking at the Internet Headers information, it seems like the front end
server as soon as it recieves an email for an account with forwarding
enabled, it carries out the forwading instruction. And when the person's
home
server receives the email, it also carries out the forwarding instruction
apparently oblivious to the fact that the front-end server has already
forwarded the email. Hence at least two (cos in some cases I get three
copies
of the same email) copies are send to my forwarding address.

How does forwarding in Exchange work? Which server is meant to carry out
the
forwarding instruction on an account?? My Exchnage "guru" internally
argued
that the forwarding is only carried out when the email hits the person's
home
server, where their mailbox is housed but based on my observation this
isnt
the case. Please shed light on this for me.

Thank you in advance

Are you using Blackberry Enterprise Server, or is he using the desktop
forwarder? In any case, you should not need to set up a rule to forward
mail
to his blackberry, the software will do the job.

HIe,

I am running Exchnage 2003. My CEO has a conatct in our organisation
that
refer to his blackberry contact. I have set the forwarding to also keep
a
copy in his mailbox.

What happens is that three copies of his forwarded email hit his
blackberry
account! Only one hits his internal mailbox.

What I ahve determined is that the front end Exchange server seems to
be
creating the additional copies. Is this how its meant to be (don think
so
cos
its such a nuisance and my CEO keeps complaining about it).

How do I tell the front end server that this guy's mail server is the
one
that will send the forwarded email and it should bother as its creating
havoc? What this also creates as a side effect is that his forwarded
email
hit his blacberry before his internal mailbox (this is due to a slow
link
in
our network which if the fornt end server wasnt sending its own
forwarded
copy of email wouldnt be happening).

Please help.
