Mailbox Replication Service (MRS) – Exchange server 2010

Moving mailboxes is a key part of managing an email service for the long-haul. There will be updated technologies, new business priorities, mergers, acquisitions, hardware and version upgrades. Moving mailboxes is an important part of managing an email service. Check out the latest Geek Out with Perry blog and video to gain some deep insights on our approach to moving mailboxes with Mailbox Replication Service (MRS) and get Perry’s take on this topic and how it works. This technology is also incredibly important if you want to move mailboxes to the cloud on your terms with a hybrid deployment.

Enjoy!!

Exchange 2010 – Distribution group email id – Not able to receive email from external source – Solution

On Exchange server 2010, If you create a distribution group with scope as Universal and type as Distribution, in your domain active directory.

and then you enable the mail from creating the mailbox server, then do the testing of email flow from internal and external.,

if you ever had face an error, “Technical details of permanent failure: SERVER tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 5.1.1 User unknown (state 14).”

Please do the following.

From your active directory, select the property of the group email id, then under mail flow settings, select Message Delivery Restrictions, then select Properties…, new window will open.

uncheck the box which states “Require that all senders are authenticated” and click ok..then apply and ok again.

Give some time to replicate this to Edge server…

Enjoy!!!!

Exchange 2010 – Attachment size – Global setting (for Send & Receive)

Attachment size setting inside Exchange server 2010 for global user settings.

  • Go to your mailbox server
  • open EMC
  • goto Organization configuration
  • goto Hub Transport
  • select global setting tab

Edit the Transport settings and change the parameters as below.

Once you done it, click Apply and ok

Remember one thing, the more you increase the size of the attachment, the load on the CAS & Edge server increase…plus the Virus scanning engine too.

Thats all folks!!!

Exchange server 2010 CAS array to MAPI load balance – Detailed

Most of you guys must have experience the scenario when “Outlook connection lost….” even if you have Exchange server 2010 (with Edge, 2 clustered H&C and 2 DAG configured MB) and Outlook 2010 in place. The reason is that, when you are doing a maintenance on one of the H&C, and if the client is connected to that H&C, communication to the MB is lost. The reason for this is that the cluster load balancing on the H&C cluster handler is not in place, even if the cluster name is published in the DNS server.

In Exchange 2007, 5 server roles that performed distinct functions within the Exchange organization. One role in particular – the Client Access server role – introduced a variety of new Web services, including the Availability service, the Auto discover service and Calendar Concierge services.

In Exchange 2010, same 5 server roles exists. However, there are some significant architectural changes and some shift in responsibilities. The most significant change in Exchange 2010, two new services on CAS called the RPC Client Access and Address Book services establish the RPC (Repote Procedure Call) endpoint for MAPI(Messaging Application Programming Interface), NSPI(Name Service Provider Interface) and RFR (Request for Response) client access. This new functionality replaces the RPC endpoints in the Information Store. The RPC endpoint in the Information Store has not been removed in Exchange 2010, but it has been modified to only accept requests from CAS servers. The RPC endpoint for public folder database access remains on the Mailbox server, however, Outlook clients now communicate directly with the RPC Client Access service on the Mailbox Server for public folder database access, and not with the Information Store.

When CAS starts communicating with the Mailbox server, it makes sense to view it as the Client Access server communicating with the Mailbox database via the Mailbox server that hosts the database. This is especially evident in a load-balanced array of Client Access servers and/or where your environment is configured to use Database Availability Groups that are associated with a Client Access server or Client Access server array.

  • In a non-load balanced environment, the mailbox database is associated with only a single Client Access server.
  • In a load-balanced environment, the Mailbox database is associated with the load balanced array of multiple Client Access servers.

By default, before a Client Access array is configured,

  • all databases are associated with a Client Access server in the environment
  • the Outlook clients communicate directly with the Client Access server until the association with the database is updated to be the Client Access array.

In order for the clients to utilize a CAS array

  1. Create a Client Access array with an FQDN (Fully Qualified Domain Name).
  2. Load balance your CAS servers in a CAS array by whatever method you choose – Both Hardware LB or Windows Network LB are supported load balancers
  3. Add the Client Access servers within the AD site to a load balanced array and in DNS associate the unique FQDN to the Virtual IP of the load-balanced array.
  4. Configure your load balancing array to load balance the MAPI RPC ports – TCP 135, UDP/TCP 6005-65535; or set static ports
  5. Configure the databases to utilize the CAS array… Use the new-clientaccessarray cmdlet to create the CAS array object. Eg: New-ClientAccessArray –Name “Tromso CAS Array” –Fqdn tromso.site.com” –Site “SITEA”

How to Setup!!!..

Goto one of the CAS server where the NLB is ( to read more about New-ClientAccessArray cmdlet, click here )

[1] Check is there are any pre-created CAS Arrays. PS Command : Get-ClientAccessArray

[2] Create new Client Access Array. Run the Cmdlet in EMS New-ClientAccessArray -Fqdn server.contoso.com -Site “Redmond” -Name “server.contoso.com”

[3] Associate databases with this CAS Array –

Use this CMDLet to add mailbox database to CAS array. Add all mailbox databases at once – Get-MailboxDatabase | Set-MailboxDatabase -RPCClientAccessServer “CASNLB.contoso.com”

Now the best part –

Configuring Outlook 2010 using Auto Discover

If you already configured Outlook client, Close the outlook, then goto Control Panel->Mail and change the Server name to the new CAS NLB name

If you are going to use a new outlook configuration, Auto discover will return the new CAS NLB name.

Thats all folks!!! Enjoy!!!

An error occurred during discovery of the database availability group topology. Error: An error occurred while attempting a cluster operation. Error: Cluster API “AddClusterNode() (MaxPercentage=12) failed with 0×80070005. Error: Access is denied.”

If the witness server you specify isn’t an Exchange 2010 server, you must add the Exchange Trusted Subsystem universal security group to the local Administrators group on the witness server. These security permissions are necessary to ensure that Exchange can create a directory and share on the witness server as needed. If the proper permissions aren’t configured, the following error is returned:
Error: An error occurred during discovery of the database availability group topology. Error: An error occurred while attempting a cluster operation. Error: Cluster API “AddClusterNode() (MaxPercentage=12) failed with 0×80070005. Error: Access is denied.”

If you specify a witness server, you must use either a host name or a fully-qualified domain name (FQDN). Using an IP address or a wildcard name isn’t supported. In addition, the witness server cannot be a member of the DAG.

Un-installing/De-commissioning Exchange server 2007 Mailbox from Passive cluster node for Exchange 2010

  1. Open the command prompt of the Passive mailbox server..make sure you logged in as domain administrator.
  2. Go to C:\Program Files\Microsoft\Exchange SErver\Bin
  3. Type the command setup /mode:uninstall

Now you have successfully uninstall the Exchange server mailbox role from the passive node, but the cluster environment server information still exists, and we need to remove that as well.

To do that we need to…

  • Open the Cluster Management Tool
  • Expand the cluster resource name
  • Expand the Nodes
  • Right click the passive node server
  • Click on More actions -> click on “Stop cluster service”

 

 Once you “Stop Cluster Service”, then click on More actions again and click Evict and click the Evict Node….

Once you done this, restart the server.

Once the server is up…do the following too

  1. Open the Server manager console
  2. Click on Features and then click on Remove Features
  3. Uncheck Failover Clustering
  4. Click on Yes to reconfirm and click on NEXT
  5. Click on Remove.
  6. After the Server is restarted
  7. Remove any remaining files and folders from the Exchange Server program files folder and subfolders.

Thats the end of Exchange Server 2007 Mailbox de-commissioning on a Passive node….Now go to the Active mailbox server of Exchange server 2007

This process is not as same like passive node. Here we can’t go with uninstall command only, because this server holds the culstered mailbox server information and it is online. In order to remove this,

Go to the command prompt..change the directory to C:\Program files\Microsoft\Exchange Server\Bin

Type command setup.com /removeCMS /CMSName:<Clustername>

This will take the mailbox now offline from the cluster…

Now type setup /mode:uninstall

Once you finish this uninstallation, Exchange server 2007 last mail box has been remove from your domain..now do the evict

Goto command prompt (If the command prompt is open, close it and open it and then type

Cluster <mailbox cluster name> node <nodename> /force

That’s the end of the “EXCHANGE SERVER 2007 DE-COMMISSIONING PROCESS”

Now you are completely depended on Exchange server 2010.

Active Directory operation failed on *DomainController*. This error is not retriable. Additional information: Insufficient access rights to perform the operation.

When you try to move a mailbox from Exchange 2007 to Exchange 2010,  following error occured:

Error:
Active Directory operation failed on *DomainController*. This error is not retriable. Additional information: Insufficient access rights to perform the operation.
Active directory response: 00002098: SecErr: DSID-03150E8A, problem 4003 (INSUFF_ACCESS_RIGHTS), data 0

The user has insufficient access rights.

Exchange Management Shell command attempted:
’*OUStructure*’ | New-MoveRequest -TargetDatabase ‘Mailbox Database 1985885663′ -BadItemLimit ‘-1′

To resolve this error…..by editing the Advanced Security Settings for that user,

  • Open Active Directory Users and Computers
  • Find the user of which the mailbox error occured
  • Open  the properties of the user and go to the security tab (if this is not available, choose view and then advanced features in the AD users and computers under  MMC)
  • Click on [Advanced]
  • Check the box at the bottom which says “Include inheritable permissions from this object’s parent” and then click [OK] twice.
Error fixing

Then try to move it and it will work…
