Adding new Hub Transport server in existing environment

Hi everyone,
Currently we have 5 exchange servers 2010 :
2 CAS Servers (Virtual)
2 MB and Hub Transport servers (Physical)
1 Edge server in DMZ. (Virtual)
Now I have added 2 more servers
with MB and Hub Tranport Roles (VIRTUAL) and want to configure the mail flow from these new transport servers.
Can anyone help with the steps I should follow. Please note we have 1 existing Edge server in 2010 and email flow should be from Hub Transport to Edge server then from Edge to internet.
Existing environment is working fine without any issues. Main reason to do this is to virtualize the physical servers. Mailbox DB already migrated to new servers.
Thanks.

Dear Manish
Please find your answers below
For mail flow to happen through new hub transport I will make the new edge subscription from new HUB server
to Edge server. Is there any other changes I have to do ?
No other changes is required
Create a new edge subscription and then import it and run start endge sync
So when I will do create the new edge subscription then it will delete the old send connectors and will
create the new one?
IT will create old edge sync and create a new edge sync which will not make any impact on your config
Will there be any downtime while doing this activity ?
Better to do this on after production hours since definitely there will be mail delay and may delay more if you try this on production hours

Redundancy For On-Premises Hub Transport Server

I'm using a Hybrid Environment - Exchange 2010 SP3 On-Premises and Exchange Online. Mail routing between the 2 systems happens through one Hub Transport server located on-premises. The default settings mandate using a certificate for SMTP connections, both
ways, as stated
here. The problem is that a certificate cannot be used twice for SMTP inside an Exchange org, so having redundancy in place would require minimum 2 valid certificates issued by a Public CA. Is there a method for getting away with only one cert and having
multiple transport servers balancing the SMTP traffic between on-premises and Exchange Online ?
Two workarounds come to mind - (1) disable requiring TLS, thus lowering security and (2) use a load balancer to offer a single virtual endpoint to be seen by Exchange Online, but put multiple Hub Transport boxes behind this (also being aware of the
Caution entry
here).
Is there another way this could be done ?

Hi,
First, I recommend you check the articles below. We must ensure that the server meets the appropriate prerequisites and system requirements before we begin our installation.
Exchange 2010 Prerequisites
http://technet.microsoft.com/en-us/library/bb691354(v=exchg.141).aspx
Exchange 2010 System Requirements
http://technet.microsoft.com/en-us/library/aa996719(v=exchg.141).aspx
Besides, I suggest you prep active directory and domain manually to check the result.
An article about how to prepare Active Directory and Domains for your reference.
Prepare Active Directory and Domains
http://technet.microsoft.com/en-us/library/bb125224(v=exchg.141).aspx
If the issue persists, in order to troubleshoot the issue more efficiently, I need to clarify some infomation:
1. Are you installing Exchange 2007 into an existing 2003 organization?
2. Did that server or computer object in AD have a prior version of Exchange on it? From the issue, it seems that you have an old Exchange server object still left in Active Directory.

Adding New Customer Address to an Existing one

Adding New Customer Address to an Existing one
Hi
We have a lot customers set up in Oracle and they only have a
ship to address and now we would like to add the bill to address
to these customers. Since there are a lot of customers I was
wondering is there is an open interface we can use to that.
Thank you
alpha

Hi Chandu,
1.In Infospoke -> General tab -> DataSouce(here infobject - 0BPARTNER).
2. Destination tab -> choose radio button(DB Table or Flat file).
3. Goto tab infoobjects -> select required fields you want to send from left to right.
4. Give the selection accordingly(here i think PATRNER). But it should be available in your datasouce(Infoobject-0BPARTNER), if you want to give selection on this. I didnt understad what you mean of <b>"hide"</b> in your previous reply. If this is not available in your infoobject(OBPARTNER), How CAN YOU GIVE SELECTION ON THIS attribute...?
5. Try to add this field in Infoobject(0BPARTNER) and populate.
6. Trnasformation tab.
Here you can see Source Structure, Target Structure and Addin implementation.
Source Structure - system will generate according to the field you selected in InfoObjects tab(You cant change it).
Target Structure - You can define your own structure if you want or you can modify the generated structure. By default system generates Target Structure same as Source structure(if you want to add any more fields you can add here, but you have to populate those fields with your own coding in BAdi), Which is Addin implementation.

Hub Transport Server

Dear All,
I have 2 mailbox servers which are in DAG with one HUB transport server it's working fine .
I have a problem with Hub transport server .If we shutdown Hub transport server the exchange mail users they can't login to email . how can we solve this ? or can i create another one Hub transport ? or which one best for
Usss.
I am waiting .

Hi Subash,
I suggest you install one HUB+CAS and configure CAS array to load balance your CAS servers.
http://blogs.technet.com/b/ucedsg/archive/2009/12/06/how-to-setup-an-exchange-2010-cas-array-to-load-balance-mapi.aspx
CAS Array will not load balance by itself you should have a load balancer. It is an object in AD. Please read this to understand about CAS array. http://exchangeserverpro.com/exchange-server-2010-cas-array/
If you have a load balancer it will load balance both HUB and CAS.
if you don't have budget for load balancer you can go with DNS RoundRobin which is not an automatic failover system. Please read these. Threads discussing about DNS RoundRobin and CAS array.

Store Driver of Hub Transport server.

Hi Team ,
I would like to know what is the "exe" name for Store driver of Hub transport Server which is responsible for putting messages to Submission Queue.

Hi,
Store.exe is a process, it indicates that Exchange information store service is running.
The store driver is a software component of the Hub Transport Server that delivers inbound messages to Microsoft Exchange stores, the databases that contain public folder stores and mailbox stores. The store driver also retrieves messages from a user's outbox,
and submits them for delivery.
Hope my clarification is helpful.

Exchange 2010 hub-transport server

i have 2 exchange 2010 hubtransport servers.
ideally when i send email my email should be load-balanced but emails send using hubcas1 goes fine and hubcas2 kepts in queues
suppose if i send at a time 5 mail
3 emails go through hubcas1
2 emails stucks in queue in hubcas2

Hi,
As you said you have added both the hub transport servers in the source server option of the send connector.Same time you have mentioned you don't have the smart host to deliver the emails to the internet and also the server hubcas2 can able to resolve the
external domain namespaces .Then do the following .
step 1 :Then please enable the protocol logging on the send connector to see the why the connections from the server hubcas2 is rejected to send emails to internet.
Step 2: Then do the outbound email test from EXRCA tool by using the ip address or name which is mapped on the MX record which belongs to the server hubcas2.
Please feel free to reply me if you have any queries .

Edge server not forwarding mail to Hub Transport server

I have an exchange 2010 VM with latest SP hosting around 500 mailboxes. I wanted to take some of the load off this box so I set up another box, loaded Exchange 2010 with the latest service pack and loaded the Edge Transport role on it. I ran the new-edgesubscription
cmdlet, copied the file to the HT server and created a new subscription. I have several sites in AD so I chose the site that corresponded to the IP address of the Exchange server. My problem is there is no mail passing between the servers. Here is what I have
tried so far:
I can telnet to port 25 on both the HT and Edge servers, and port 50636 on edge server.
I can ping NetBIOS and DNS name of both machines from each other.
DNS suffix was added PRIOR to installing edge transport role.
Running get-edgesubscription on HT shows the Site being used, but on Edge site is blank, is this normal?
If I run start-edgesynchronization, I can see the data being replicated to the edge.
If I run test-edgesynchronization from HT, the status is Normal.
If I run get-exchangecertificate and look at the cert thumbprint on both boxes, they are different (from what I read they should be?)
Two Send connectors are created and they are both replicated to the edge, along with accepted domains.
Initially, when I created the subscription, I looked in event viewer on HT and saw Event ID 10104 and 1024, but running start-synchronization seemed to replicate so I thought it may be a one time error. This may be my issue. I have a 3rd party cert on my
HT server to accept mail and allow TLS to mail.mydomain.com. Any help would be greatly appreciated. I'm ready to pull my hair out. I have reloaded this edge server twice trying to figure out what is going on.
Jeff Green MCSA/MCSE 2003, MCITP 2008

OK, first off, I'm not sure that adding an Edge server is going to reduce any of the load on your mailbox server - all emails bound for your system are going to hit the mailbox server anyway, so unless you have huge amounts of spam and viruses bound for
your system, the savings will be negligible.
That being said, it's not a bad thing to deploy an Edge Server. So let's see if we can figure out why yours isn't working as expected. When you deployed the edge, did you follow all the steps in the following two articles?
http://technet.microsoft.com/en-us/library/bb124011(v=exchg.141).aspx
http://exchangeserverpro.com/exchange-2010-install-edge-transport-server/
If you did follow the steps, do you now see the Edge Server in the list of Exchange servers in the EMC under Server Configuration (not one of its subnodes)?

Hub Transport Server Routing

Hello All,
We have two AD sites consist of below. Exchange 2010 HT server @ Site 1 is routing mails to both Hub transport Servers @ Site 2. How do i enforce HT server @ site 1 to send all to 2010 HT server @ Site 2 without shutting down the 2007 HT.
Site 1
AD 2008 Server
Exchange 2010 HT/CAS
Exchange 2010 Mailbox
Site 2
AD 2008 Server
Exchange 2010 HT/CAS -> Send Connector source server for external domain.
Exchange 2010 Mailbox
Exchange 2007 HT/CAS

There are by default hidden internal connectors between all the Hub Transport servers so emails can be routed out-of-the-box automatically to all parts of the mail infrastructure without any additional need for manual connectors. It would be good to turn
up logging on these hidden connectors by running the cmdlet below (source is
here, section "Use the Shell to enable or disable protocol logging on the intra-organization Send connector"). This will yield if indeed mails are routed from your 2010 HT in Site1 to the 2007 HT in Site2.
If all mailboxes are moved from 2007, what is the point of keeping that server online ? For manually blocking connections - or making it so that a connection to it is not selected you could either (1) change the default IP ranges the 2007 listens on as to
avoid the 2010 HT in the first site or (2) create a separate AD site specifically for the 2007 HT server's IP (this will increase the cost of the route from the 2010 HT in Site1, making it unattractive for delivering outside mails. However please note that
these 2 methods are overkill and it would be best to see the exact reason of still keeping the 2007 box.

Adding new airport extreme to an existing airport express network...

i currently have a home airport network comprising two airport express units; one attached to the cable modem in the bedroom and the other downstairs in my study (extending the existing network and feeding a shared USB printer and airtunes speakers). i've recently bought an airport extreme, to improve network performance. i also plan to add a NAS in the next week or so.
ideally i'd like to situate the new airport extreme in the study, as i don't want to have to keep the NAS in my bedroom!
my question is this, if i add the new airport extreme to the existing airport network, will i see the benefit of the 802.11n connection, or should the extreme be set up as the primary base station?

... will i see slower transfer speeds (than if it was connected to the extreme) to / from the NAS when accessing it wirelessly from elsewhere in the house?
No. The transfer speed will be limited by the slowest connection, which is almost certainly your wireless connection speed.
If you buy a switch, buy a gigabit switch. Not because a slower one will limit your transfer speed, but because the Extreme is Gigabit and any newer equipment is likely to be as well. The advantage would only be relevant to the wired LAN.
The Express's Ethernet is not Gigabit but there is no reason for it to be, since it cannot connect to anything other than a slower wireless connection anyway.

Error while adding new OVM in server pool

Hi,
Did the subscriber database used for replication before?
Check the MSDistribution_history table in the distribution database. It contains history rows for the Distribution Agents.
In case you encounter the “One or more subscriptions have been marked inactive. Drop and re-create all subscriptions for this node that are failing with this error.” in the Replication Monitor after restarting the Distribution
Agent.
This means that the Distribution Agent is unable to delivery data due to some errors or the job was stopped and the Agent will go into an infinite retry logic.
The Agent will stay in retry mode until the Distribution Cleanup job removes the “cached” transactions from the Distribution Database. At this point the Distribution Agent will no longer have the data needed to “catch
up” the subscriber. As result, the Subscriber will be marked “inactive” and post the following error in the MSrepl_errors table in the Distribution database.

Integrate new MA without changing the existing environment

Hi,
Can any one please suggest me for the below scenario.
Consider in the current environment. , we have deployed FIM sync server and configured three management agent of type ADDS. There are some rule extension deployed for exchange and Lync. FIM Portal and MS Bhold is not installed and used. Total
number of user are 15k.
Now we have new requirement to integrate a new AD and new Ldap management agent to provision and provision 500 user.
For these new 500 users, we also need FIM Portal and MS Bhold.
We don't want to make any change in the existing configured MA. Can we implement like this.
1. Install FIM Portal and MS bhold on the existing server on which FIM syn server is already installed.
2. Configured the new management for new AD and Ldap.
3. Configured the FIMMA to allow only the new 500 user to provision in FIMService based on some criteria which can get from the new AD and Ldap.
4. Do the required configuration of MPR,Syn rule etc in FIM Portal.
5 .Do the configuration export and import the user in Bhold for only new 500 users to approval, groups management etc.
OR
Install the FIM Portal and Bhold and then reconfigure the all exiting management agent using the FIM Portal GUI.
Please suggest which is best way. If we need to reconfigure the all the existing MA using FIM Portal or just install the FIM Portal and Bhold and configure the required MA for new 500 users only.
Thanks
Harry

Thanks Dominik for your response,
So it means there will not be any performance issue if we keeps existing MA in Synchronization server (without FIM Portal) and install the FIM portal and Bhold to manage and create new AD and LDAP MA for new 500 users using FIM Portal GUI.
As well as per my understanding, only 500 cals Licence will be required because only new 500 users will be managed by FIM Portal (FIMService) and MS Bhold. Cals license will not be required for rest old 15K user because these
will be managed by only by Synchronization server(FIMSynchronizationService ) not FIMSevice.
Please correct me.
Thanks
Harry

Adding new value fields to an existing and productive operating concern

Hi,
I would like to have 5 new value fields active in 4 out of 6 operating concerns that I am working with.
Is it correct that I could do this one of the following ways:
1. Use a value field that exists already in an operating concern and rename it?
In this case is it necessary to regenerate the operating concern?
Do I transport the change ?
2. Create an entirely new value field, and assign it to the operating concern?
Is it necessary to regenerate the operating concerns in question?
Do I transport the change?
3. Select a value field that is currently in the system but is not assigned to any operating concern eg some kind of SAP delivered value field? How do I assign it to the op con? Do I need to re gen the op con?
Which way is the best or is there a 4th option?
Thanks for your help in adviance
Regards
Aisling

Hi,
This note is a catalogue of notes of consulting notes where SAP tell you steps, reports to use and son . If you read them (these notes and related notes) you have the steps, guides, reports that you must use. Better advice. Try a solution with all steps in mind and check it in a quality enviroment. As you know there a lot of things in CO-PA concern (you have your own tables, with your own fields, your reports as KE2Rxxxx, and so on), your secondary indexes, etc.. , the best is try the solution in your Quality Enviroment (a quasi-clone of your production enviroment) and check the results (create SO, invoices, after modifications to check possible problems,...).
Regards,
Eduardo
pd: I forgot. If the size of tables (CE4xxxx, CE1XXXX, ...check them with DB02) are so big, get the opinion of a Basis Consultant. Surely in the before note there notes about this issue.

Adding new custom field in already existing custom tab for MM01

Hello Guru,
I have a requirement that add a custom field in already existing custom view of MM01. I did the following steps :
1. I have cerated a new field in MARA using APPEND structure.
2. I have found the function group(Y_FE_MARA) that already there other subscreens, so that I have added another subscreen in that function group and created a field from MARA in the screen.
3. in SPRO went for the path Logistics General->Material Master->Configuring the Material->Define Structure of Data screens for Each Screen sequence
In the 3rd step, I have choosen already existing screen sequence(Y1) and went for Data Screens and choosen for Custom tab and double click on subscreens and then I have added the program as SAPLY_FE_MARA and subscreen number(011) and saved it.
After all the above steps, I have run MM02/MM03 then the field is not getting displayed in the screen of custom view.
Did I miss any steps here? Please suggest me if I did something wrong.
Thanks and Regards,
Muralikrishna Peravali

Hi Raymond,
Thank you for the reply. As per the note some one already implemented the Screen Enhancement with 2 custom views. I need to add the field in any one of existing custom view. So for this I have created a Subscreen in copied function group of MGD1(Y_FE_MARA). But in the function group already 10 Subscreens were created. Is this is the problem? or else copy the FG MGD1 into another FG and create the subscreen will be feasible to my scenario?
Please suggest me.
Thanks and Regards,
Muralikrishna Peravali
