Hi everyone. Company1 has been around for 25 years. It currently has a

Windows 2003 Enterprise R2 domain running Exchange 2003 Enterprise Edition.

Company1 created a completely new company, Company2. Management doesn't want

Company1 and Company2 to be affiliated in any way as far as the outside

world is concerned. However on the inside Management wants the following:

1. Some employees with remain exclusively with Company1.

2. Some employees will be moved to Company2.

3. Some employees will be with both companies and need to be able to send

out e-mail from either company separately from @company1.com and

@company2.com.

4. They want to able to share/view calendars between Company1 and Company2.

By the way, Company1 and Company2 will be at the exact same physical

location and located on the same LAN.

OK, now it gets even crazier. At the same time Company1 has purchased

another company, Company3. Company3 is located three thousand miles away.

They have a Windows 2008 Domain and their e-mail server is hosted at a

outside hosting provider. A VPN connection through the Internet is setup

between Company1 and Company3 but the forests/domains are not trusted. Just

as with Company2 Management doesn't want Company3 to be affiliated in any

way as far as the outside world is concerned with Company1 or Company2 but

on the inside they want all three companies to be able to share/view

calendars and be able to send e-mail out of their respective domains,

@company1.com, @company2.com, and @company3.com. I told you this was crazy.

The big thing that Management wants to be able to do is share/view calendars

across all three companies. I really need some help with this one. I am not

sure if this can be done. I would appreciate any advice. Thanks for the

help.

It's not difficult to host multiple public/Internet domain names in

Exchange - through the cunning use of recipient policies you could ensure

that anyone in Company1 gets user@company1.com for email, and same for

Company2 and Company3.

The issue is, does management care if savvy recipients can tell that

company1, company2, and company3 mail are hosted on the same Exchange server

(by looking in the headers, etc)? If not, this is not a big deal to set up.

The only problem you will run into is if they want a user to have email

addresses on both/all domains - you can't send mail from anything but the

default SMTP address without third party add-ins (ChooseFrom at

www.ivasoft.biz) or some very convoluted settings which I don't recommend

for a company this size.

This is the rub right here. Sometimes companies don't care, but sometimes

they do and that opens a whole new can of worms

Thanks Lanwench and Martin for the quick replies. Unfortunately they do care

because they could get in trouble with some of their Partners if it

discovered that Company1, Company2, and Company3 are tied together in any

way. I should also throw it out there that they are willing to spend money

to get a proper solution. If that means setting up additional

forests/domains, purchasing servers, purchasing additional Internet

connections, etc., they will do that. Let me know what you think. I have

never come across a situation like this before. Is there any chance that the

new version of Exchange, Exchange 2010, and the new version of Outlook that

are going to be released at the end of this year will help in this scenario.

I may be able to convince them to hold off until those products come out if

they will help.

Thanks

Why not move Company1 and Company2 to the Cloud with Company3 email.

That way they all have their own AD, and have unity in email only.

Probably cheaper ultimately too.

This was exactly what I was thinking. I would move them to the cloud and let

them rip.

It will almost certainly cost less than deploying more orgs.

Yep. But will they be able to collaborate/share between them?

They could be provisioned as a single Cloud Customer so yes. Also if they

were setup and configured as 3 seperate Cloud customers if the Provider is

decent, then yes they should still be able too.

Setting up a single cloud with three sites that can share calendars

internally sounds very appealing. Any recommendations on providers that can

do something like this. I contacted RackSpace, www.rackspace.com, and they

said they couldn't do it. Thanks.

I just talked to Microsoft since they offer Hosted Exchange too and they

said it can't be done either. They have be in the same domain to view/share

calendars.

Do you really mean "share" calendars, or did you mean that they should

be able to see each other's free/busy times? The two are very

different.

See each other's free/busy times. Basically act like one organization.
