Email Address Policy in Exchange 2007

Hi there,

Managing SBS2008 with Exchange 2007, I am tasked with assigning email addresses from their multiple accepted domains, dependent on their Company/Department settings in each user's Organisation tab.

Does EAP stop being applied to a user once that user meets the selection criteria? Or, is it cumulative? In other words, if I have multiple EAPs, will all EAPs be applied to the same user as long as they meet the selection criteria?

If the answer to the previous questions is that only the highest priority EAP is applied to any one user, is it a case of a different EAPs for each combination of scenarios?

For example...

ACCEPTED DOMAINS
thebigcorp.com
business1.com
business2.com

COMPANY OPTIONS IN ORGANISATION TAB
The Big Corp

DEPARTMENT OPTIONS IN ORGANISATION TAB
All if user is to have all email addresses
Business 1 if user is to have an email address @business1.com
Business 2 if user is to have an email address @business2.com

POSSIBLE SCENARIOS
The user has a blank COMPANY and a blank DEPARTMENT: they get the email address thebigcorp.local
The user has The Big Corp as their COMPANY and a blank DEPARTMENT: they get email addresses at thebigcorp.local and thebigcorp.com (set as a the reply)
The user has The Big Corp as their company and Business 1 as their DEPARTMENT: they get email addresses at thebigcorp.local, thebigcorp.com and business1.com (set as the reply)
The user has The Big Corp as their COMPANY and Business 2 as their DEPARTMENT: they get email addresses at thebigcorp.local, thebigcorp.com and business2.com (set as reply)
The user has The Big Corp as their COMPANY and All as their DEPARTMENT: they get email addresses at thebigcorp.local, thebigcorp.com (set as reply), business1.com and business2.com
The user has a blank COMPANY and Business 1 as their DEPARTMENT: they get email addresses at thebigcorp.local and business1.com (set as reply)
The user has a blank COMPANY and Business 2 as their DEPARTMENT: they get email addresses at thebigcorp.local and business2.com (set as reply)
The user has a blank COMPANY and All as their DEPARTMENT: they get email addresses at thebigcorp.local (set as reply), business1.com and business2.com.

I guess what I'm really asking is, "What is best practise for implementing such a scenario"?

Thanks in advance.

Regs,
Bill.

Hi,

As far as I know (I just chekced it on my exchange 2010 server) it only applies the EAP with the highest priority that matches. So you need to create a different EAP for all combinations and make sure you get the priority right.

One note, it looks like the EAP add's the new policy so it doesn't remove existing aliases
Thanks ronnypot. I've already spotted that gotcha! It would be nice if you were given the option to remove all addresses and apply only those dictated by EAP.

I've also done some testing of my own and have come to realise that multiple EAPs, covering all scenarios, are need.

Having said that, I have noticed in my testing that the "Default" policy is applied, regardless of which of the higher EAPs were also applied.

So, in summary, it appears that the highest priority EAP meeting the selection criteria is applied AS WELL AS the default EAP policy.

Would everyone agree with this?

In the absense of any further enlightenment, I will accept ronnypot's as the solution.

I just checked that but if you have created new EAP's the default EAP isn't applyed anymore.

I created a new user and it only applies the EAP with priority 1 and not the default

I host a SBS 2008 for three businesses and have a similar requirement as far as using EAP with a dependent on the Company field in AD. My issue is that when we use the SBS Console to create a User there are no options to add a Company - so what I need to do is then go into AD and add the Company Name and then apply the appropriate EAP.

Does anyone have any better solution for me?
I was a little disappointed that no Exchange Experts jumped in with advice. It seemed ronnypot and I muddled through on our own.

Did I post the question in the wrong group?
