How can I send email to two different emails account for the same
person at the same time using exchage server.
Example: I am trying to send email to someone@go.com in the network at
the same time I wanted to farward it to the same person who has
different account like someone@gmail.com and someone@hotmail
Using Microsoft Exchange server.
So by typing his only network email address I wanted to be able to
send (forward)to his gmail and hotmail. at the same time.

Thanks.

Well, I'm not particularly familiar with the type of email program you
are using, and this may not be the answer you're looking for, but in
my experience, you can usually type johndoe@gmail.com,
johndoe@hotmail.com etc. THe key to that being the place of the comma
and a space between email addresses. Alternatively, you can utiilize
to CC or BCC function if available. Those stand for Carbon Copy and
Blind Carbon Copy, respectively. CC works by sending a copy of the
email to another address, while informing the original recipient that
you have done so. BCC sends a copy just like CC, but does not inform
the original recipient that a copy has been sent elsewhere.

i tihnk if you put BOTH address in your address book under one name,
then send it TO THE NAME, it will work...not sure tho...

youre example differs from the initial question. In answer to the
initial question you could set up a distribution list and add the
various members who you want to be emailed to this list. If you then
want a copy emailed to another address you could just add a filter.

In Outlook, create a distribution list - FILE / NEW / DISTRIBUTION LIST.

Add the appropriate contacts or email addresses.  send your email to
the new distribution list instead of individuals.

I agree with Rafikki.  On Mozilla Thunderbird, one can enter multiple
primary addresses (each on a new line), as well as CC and BC.
