Hello Everyone,

I need suggestions on following Scenario.

Currently we have
- Primary AD server 2008
- HUB/CAS 2010 server
- Mailbox Server 2010
total 3 servers at the office for messaging.
What we want to do is, we want to deploy new server (HUB/CAS/Mailbox) at the ISP or another location with stable internet link.

So, someone send an email to us, it should reach to our new server at the ISP or new location first, then copy of mail should reach to current servers at the office.

The main reason is, our primary internet connection is not too stable and we want to receive emails while our internet connection down.

Also want to know that, do we need to move our AD to new location?
How about License, we need to buy same licenses for new location?

Hi,

Since it will create a lot of complexity and I am doubting if it is supported I wouldn't recommend this solution.

I would rather ask your ISP if it is possible to use a fallback mailserver of them. This fallback server will also be listed as MX record in your DNS configuration.

What happens if the internet connection is down mail will be delivered to your fallback server. Once your connection is back online it will deliver the mail to your server.

Regards,
Johan

Thanks for your reply Johan,

But I'm still confusing with

What type of Mail Server that we should place at the ISP?
(i.e - exchange 2010 HUB/CAS/MAILbox)

In your email you said, that fallback server will receiving emails while our primary ones is down.

so that server should includes (HUB/CAS/MAILbox)? also Active Directory connection??

Can you explain more detail? I'm a bit novice in exchange.

Thanks!

It looks like you are looking for a workaround when the solution is to upgrade your internet connection or change providers so you have a stable connection. I also would not recommend your proposed plan for a number of reasons:
  1. Placing a server at your ISP would mean that you are stretching your active directory to your ISP, greatly reducing security for your domain
  2. The failback solution you are looking for will not work because of the way exchange is designed. You can only have one mailbox in an Exchange organization so configuring the "forwarding" will be a little bit complex.

In my opinion, you have two options:
  1. Upgrade your internet connectionr
  2. Register with 3rd party mail services like mimecast or postini. Not only will they do virus scanning and spam filtering for you, they will also hold your email in the case your exchange is not reachable. Once connection is re-established, all the held mail will be sent to your organization.

Hi,

As de.blackman said postini or a mailserver from your provider probably not an exchange server but something linux based.

Johan

Guys!

How about we deploy a new HUB/CAS Server on backup internet link?

And make DNS MX record with priority

@ MX 10 current.mail.server.com
@ MX 20 Backup.mail.server.com

HUB / CAS Server -----> Primary internet Link

HUB / CAS Server ---> Backup internet link

MailBox Server

please advice.

You are not going to want to do that. If it even works (dont see how, unless you have a vpn to your ISP.

I think what you mean is have an externally hosted mail relay. Fine, do a send connector and receive connector for their host. Very easy and supported.

There is more to why you cant do what you are suggesting than I have time or desire to put in an email.
