Alternate sender email address

Posted on 2009-02-11

Our exchange server is authoritative for several domains.  Our sales staff mostly have Outlook 2003.  We are just installing Exchange 2007 and will maintain a seperate database for 2 of the domains.  Sometimes the sales staff needs to send email with their address being from @domain1 and other times @domain2.  (This is not a case where the 'from' field can be used since they are sending as themselves, not on behalf of someone else.)  Is there some method to achieve this?  It would be particularly helpful if there was some way to reply with the domain name that the email was sent to, rather than having to choose which identity to use.  Another issue would be duplication of email addresses in the GAL.  Any thoughts would be appreciated.  BTW- has anyone used the new exchange 2007 rules to separate out emails into different containers based on the email address it is sent to?

    If there are separate mailboxes then the From field is what you need to use. The primary account needs to be granted Send As permissions.

    Just to clarify - the mailboxes are the same - there are different email addresses within the same user account Joe@domain1 and joe@domain2.  What we are trying to achieve is to use one profile for both email addresses.  As an alternative if under exchange 2007 we add a separate database and put the alternate mailbox and email address there and then give the user full security to that mailbox they can open it under there main account - but this will create duplicate entries into the GAL

    If the email addresses are on the same account, then you cannot select which address the email comes from. As far as Exchange is concerned all users only have one email address - the default. All other addresses are aliases for inbound only.
    If you want to use two different addresses then it has to be multiple accounts or a third party tool such as ChooseFrom from

    Where you locate the mailbox doesn't matter, it does not have to be on a different database.

    Thanks for the suggestion of Choosefrom - I agree with you in terms of the inability of outlook and exchange to do this by themselves but if you don't ask you don't find out.

    Granting full access permission allows users to access mailboxes present in their database. By giving full access permission one can open and read the content of any mailbox but cannot send emails from that mailbox.
