Send As Permissions on Additional Domain on Exchnage 2007

Hi all,

I have googled but with no luck.

on our exchange server it has the primary domain 'companya' and all boxes are setup using this.

Now I have an additional domain that I want to be able to receive and send as from 'companyb'.

I have added the domain tot he accepted domains i.e.;

Exchange -> Organization Configuration ->Hub Transport -> Accepted Domains

and added the relevant accepted email address to the users i.e.;

Receipient Configuration -> Mailbox -> selected box -> email-addresses

So I can receive from info@companyb.co.uk inside info@companya.co.uk's mailbox.

However, when I try to send as info@companyb.co.uk from outlook i receive the following error

You are not allowed to send this message because you are trying to send on behalf of another sender without permission to do so. Please verify that you are sending on behalf of the correct sender, or ask your system administrator to help you get the required permission.

Hi,

many thanks for this.

OK, I have added the emailaddress policy for y 'companyb.co.uk' i have done the following;

Exchange -> Organisation Configuration -> Hub Transport -> New Email Address Policy...

I have then for all receipients added the rule %m@companyb.co.uk

This is added with the priority of 1.

However, when I then try to send (from mailbox user@companya.co.uk) as help@companyb.co.uk (help@companyb.co.uk is listed as an email address in the user@companya.co.uk list), I receive the following error email;

You are not allowed to send this message because you are trying to send on behalf of another sender without permission to do so. Please verify that you are sending on behalf of the correct sender, or ask your system administrator to help you get the required permission.

so a step forward i think but how do I add the permissions?

Hi MAS,

I was hoping that we could get away with this ait was just a generic website email. i.e.

services@companyb.co.uk is set to be received by usera@companya.co.uk.

I was then hoping that when the mail comes into usera@companya.co.uk, they could reply with the services@companyb.co.uk.

if this is not possible sending as usera@companyb.co.uk would be good.

I have tested this functionality (i.e. sending as usera@companyb.co.uk from usera@companya.co.uk) and I am still getting the you are not allowed error? Am I missing a step?

Yes if you follow the steps above you should not be getting that error
