Message Tracking in Exchange 2010

For the Message Tracking in Exchange 2010, it can't show the recipients field. Any idea ?

In our current setup, all external receipents are routed through a smart host provided by our ISP. Will that be the problem ?

Hi, if you open the message tracking log on the hub server do you see the recepients?

The hub role is installed on the same server.

Does it caused by the smart host as there is no record shown in Exchange ..

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

florin_sCommented:
well, I do not think that this is because of the smart host

If you perform a message tranking with powershell do you see the recepients?

Find some hint for the problem. We have two exchange ex1 and ex2 running in DAG. EX1 is currently active. I suppose all the emails should go through EX1.

When I run the Message tracker on EX1, I can't see the recipent email. However, I can find it on EX2.

Any idea ?

if you have two hub servers the message flow is automatically balanced between them, and you have to look on both to find the messages

Even under DAG, both EX1 & EX2 will be used for mail routing ? Under Organization Configuration --> Database Management, the mail database for EX01 is shown as active while EX02 is not.

the hub servers are not load balanced automatically, my mistake here :), they are load balanced if you have a NLB or something else there in front of them

It seems to me that you don't so you have to do the message tracking on the one that is configured for routing

Under Database Management you see the active / passive databases(you can click on one and see on which server it is active), this is not related to what we have discussed, I mean the routing.

EX1 is the active mailbox database currently.

I just come up with an idea. Will there be a possibility that Hub Transport role can be shared between two exchange, EX1 & EX2 but database role can only active on EX1. If that's true, it can explain the transport role is taking care by EX2.

If the transport role is installed on two exchange servers but in front of your HUB's you don't have any load balancing then the routing will take place with only one HUB

The MBX servers in a DAG environment can be configured so that one is active and one passive

Sorry, what do u mean "transport role is installed on two exchange servers but in front of your HUB's" ?

So, only one Exchange will be picked for transport role.. but why EX2 is selected instead of EX1 ?

Any criteria ?

"You can install the Hub Transport server role on the same hardware with any other internal server role or on a server that's dedicated to the Hub Transport server role. You must deploy a Hub Transport server role in each Active Directory site that contains a Mailbox server role. Deploying more than one Hub Transport server per site provides redundancy. When you install more than one Hub Transport server in an Active Directory site, the connections are distributed."

In my case, two hub transport roles are installed on two Exchange, do u mean the standby Ex2 can take up the hub transport role ?

Tks. My case is outgoing emails, not incoming emails. And no NLB is configured.

In this case, can the email use EX2 for outgoing email although EX2 is not active under DAG database Management.

Tks again.

The DAG has nothing to do with the routing.
For the outgoing emails you can do this by sending them directly into the internet or to a smarthost from a provider

To test my understanding, does both EX1 & EX2 currently involve in Hub Transport ? I haven't setup Window NLB ?

No only one HUB is used, normally you can configure the load balancing from DNS (this is the cheap way)

You can not configure Windows NLB because it is not supported.

The expensive way is to buy a Hardware Load Balancer

So, why EX2 is used instead of EX1 when sending emails outside ?
0
florin_sCommented:
one of them is used, it depends which one you have configured, only one if you haven't configured some load balancing method

AXISHKAuthor Commented:
Last question,

Both EX1 & EX2 is used as transport role and EX2 is picked up as Hub transport. In case EX2 is fail, will Exchange use EX1 for mail transport ?

Tks

florin_sCommented:
you have to configure it manually to pick up the messages

AXISHKAuthor Commented:
Sorry. Where should I manually configure to use another Transport server (ie, EX1) even though I have already put these two servers under source tab in case EX1 is failure ?


Great thank.

For internal use (within your AD environment) you do not have to do anything special to configure the HUB servers,for load balancing, they load balance the mail traffic by default.

For external use, please see this link: http://araihan.wordpress.com/2010/03/17/how-to-configure-exchange-2010-hub-transport-ht-server/

This link also explains the hub-cas scenarios: http://social.technet.microsoft.com/Forums/exchange/en-US/3230ffc6-8b4d-4393-a0ef-5d3398a3126e/redundancy-hubtransport-exchange-server-2010

But I think this is another topic than your original one, and if you wish to discuss it further please open another question
