How to make the Emails you Send with Outlook and
Exchange Appear to Originate from Different Addresses
If you only have a single email address from which you send all your
business and personal emails then you're lucky that life is so simple, email-wise.
It's quite common to need to make the emails you send appear
to originate from different email addresses, depending in which capacity
you are sending the email or which company you happen to be representing.
Confusion or embarrassment can be caused if you reply to
an email with the wrong "From" address. You may be support@ and
sales@ for Company A, and info@ and webmaster@ Company B plus the many other
personal email addresses you have accumulated.
If you use signatures on
you emails you may also need a different signature to match each "From" address.
If you use Outlook and Exchange for your emails, there's more than one
way to have multiple "From" addresses but here is the simplest, most convenient way:-
In addition to your main Exchange account, set up a
dummy POP3/SMTP account in Outlook for each "Send As" address.
Receiving all the emails sent to different addresses in not so hard.
You can have an unlimited amount of alternative email addresses, called
"aliases", assigned to your Exchange account in
addition to your primary email address. Exchange then knows that emails
addressed to any of your aliases belong in your Inbox.
Alternatively, emails to generic addresses such as sales@ can go to the
Sales public folder which you, and other,s can share the task of monitoring and
replying to.
When you click "Reply" to any email in your
Exchange mailbox, or a Public Folder, it doesn't matter who the original
email was addressed to, Exchange always uses your primary email address in the "From" header.
Your primary email address can be changed to any of
your aliases, but not very conveniently. With multiple
POP3/SMTP accounts setup, you can quickly select the "From" address you want to use
which will then, automatically take the signature assigned to that
account. The email you send this way will show the appropriate address in the
"From" and "Return-Path" headers and won't have any of your other email
aliases hidden anywhere else in the email.
You should choose your Exchange primary email address as the one
you will send from the most or the one that will cause least
embarrassment if you forget to change the "From" address from its default.
If you actually received the emails to your aliases via these POP3/SMTP
accounts then Outlook would automatically set the "From" address as the
"To" address of the email you were replying to.
Don't even think about it: the advantages of having all of your email come directly into
Exchange far outweigh this small advantage.
All new emails and replies will therefore default to having your
primary email address as the "From" address.
You need a person with administrative privileges on the Exchange server
to set your primary email address - that's us. You can
email us at info@arrowmail.co.uk to request a change to your primary email address.
This webform should also be used to tell us which aliases you want
associating with your account, and, if these aliases require us to
collect email from a 3rd party POP3 mailbox, we'll need the POP3 server
name and your username and password for it.
You can setup all the extra POP3/SMTP accounts yourself and choose anything at all as
the "From" address without having to consult us.
(There would, however, be no point setting the "From" address to an address where you can't access the replies.)
A copy of all emails you send from an alias address will appear in your Exchange Sent Items folder and be labelled
with the account they were sent from.
Step-by-Step Instructions for Setting Up Different "Send As" Aliases
In Outlook go to:-
Tools - E-mail Accounts… - View or change existing e-mail accounts

The instructions and screen-shots on this page are for Outlook 2003.
The same procedures work equally well for Outlook 2007 except the screen-shots are different.
At some stage we'll prepare an alternate version of this page for Outlook 2007 users. |

You can see, above, there is a single Exchange account and the name
has been set to the Exchange primary email address of johns@arrowmail.co.uk.
The default name for this account is "Microsoft Exchange Server" and if yours says this,
click Change.. - More Settings… and change this to your
primary email address - you'll see why this is a good idea in a minute.
Now click on Add.. - POP3 - Next > and fill in the account details to match your first alias:-
|
|
 |
Notice that the Incoming mail server (POP3) has been given a dummy value.
Under no circumstances do you want to receive any email from this POP3 account so it's best to use a bogus value.
Set the User Information to how you want your email to appear in the recipient's inbox.
The Logon Information is for your Exchange server account which is required for sending email.
Click More Settings…
On the General tab change the name of the account to the alias.
It's not necessary to type anything in the Organization and Reply E-mail boxes
but we recommend putting your alias address again in the Reply E-mail
box to keep those fussy spam filters happy.

On the Outgoing Server tab select My outgoing server (SMTP)
requires authentication and Use same settings as my incoming server.
There's nothing to do on the Connection tab.
On the Advanced tab you can, if you wish, select:- This server requires an encrypted connection (SSL)
This will make emails sent between Outlook and Exchange use an encrypted
connection. However, it doesn't guarantee that your emails
will remain encrypted for the entire journey to the recipient's inbox as, once it's left our servers,
it's out of our control.
Repeat this process to add more "Send As" aliases and when you've
finished, the E-mail Accounts page will look something like this:-

You can use the Gmail web interface to forward all emails to PhantomMenace@gmail.com to
john.smith@arrowmail.co.uk and, for the other 3 accounts, you can let us
know the POP3 server, username and password details and we will
configure our servers to check for and download, new emails to your
Exchange Inbox every 15 minutes.
Email us at info@arrowmail.co.uk to give us the required configuration information.
The final step is to prevent these new POP/SMTP accounts from attempting to collect email and causing an
error message. From Outlook, click on the down-arrowhead next to the Send/Receive button:-

and select Define Send/Receive Groups… from the drop-down menus:-
|
|
 |
Select the All Accounts group and then click Edit…

Except for your main Exchange account, select each account in turn and make sure
Include the selected account in this group and Send mail items are
both ticked and Receive mail items is unticked:-

Creating a New Email and Choosing the "Send As" Alias
In Outlook, when you click New to open a new email window you can see that there is an Accounts option:-

Click Accounts to get a drop down list of the available "From" addresses:-

Select the required account and the new email shows a message confirming which account will be used to send the email:-

If different signatures have been setup for the accounts in:-
Outlook - Tools - Options - Mail Format - Signatures then the correct signature
will be automatically applied to the new email when you change the "From" address.
For this to work correctly, all accounts must have been assigned a signature.
If you don't want an account to have a signature then make a new
signature called Nothing, which is blank, and assign it to that account.
When typing in the body of the email it's easy to stray into the signature area.
This is fine unless you then change the account you are sending from and the signature changes.
This will cause any text, from the body of the email, that you typed in the signature area to disappear.
To prevent this, it's a good idea to start the signature with a visible divider, such as a row of dots:-

Any Stationery and Fonts option that you select in Outlook will be
applied to all accounts so we advise you to just use signatures to
achieve any "branding" or fancy effects.
Is this the Perfect solution for multiple "Send As" aliases?
Not quite, but it beats any other method I've seen. Here are some of the problems:-
|
|
1 - |
When you send emails from an alias, the emails travel to our servers using the SMTP protocol over port 25.
You can select to use secure SMTP instead of standard SMTP and so
security isn't an issue, but getting through firewalls might be. All other communications between Outlook and
Exchange use TCP port 443 which is a good bet to be open on almost any
firewall you meet while SMTP Port 25 is a fairly common port to block as
viruses can use this port to send their own emails. You may therefore,
occasionally find a situation where you can receive all emails and send
ones using your primary email address but any email sent from an alias
remains stuck in your Outbox. We offer the option to connect to our servers over a VPN connection that
uses different TCP ports again but, while this gives you another option,
the required VPN ports may also not make it through the firewall that's blocking SMTP.
If all else fails we've setup a webpage for Arrowmail customers which just
requires HTTP to send an email and you can use any From address from the domains
you've registered with us:-
http://websend.arrowmail.co.uk
|

Outlook Web Access has no "Send As" option and so all emails you send will show
as originating from your primary email address. If this is a
problem, the http://websend.arrowmail.co.uk webpage
is available for Arrowmail customers.

The Microsoft way of sending as another user is to allocate your account the
"Send As" permission within Exchange for various other real accounts, such as a
mail-enabled public folders, or dummy accounts that have been setup just
to provide you an alias. Using the POP3/SMTP account method we recommend,
bypasses all this "Send As" permission checking and allows you to "Send As"
whoever you want, even the managing director. If people sending
emails from addresses they shouldn't is ever a problem, then the
Exchange server logs will show which username was used to authenticate for sending each email.
If you're an Arrowmail customer
and your users know about our
http://websend.arrowmail.co.uk page then they can send their email from there instead.
