Hi,
  I'm trying to create mailbox enable users in Exchange 2010 using C# .Net web serive, but it is not working. Same code works well as a console application. Web service is returning "No provisioning handler is installed" which is basically happening when it invokes "Enable-Mailbox" command. Please see the code attached below, if I change the command to "Get-Mailbox" then the same web service functions without any issue.

Infrastructure Details:

• Windows 2008 R2 Server
• IIS 6.1
• Exchange 2010 Management tool
• Visual studio 2008

The place which return error is loacted at the line has the following code "if (pipeLine.Error != null && pipeLine.Error.Count > 0)". Please help me with this, I would appreciate if anyone have done Exchange 2010 Mailbox provisioning with C# Web Service and help me out. Thanks in advance.

Testing this in a lab to fill in a knowledge gap just incase it ever comes up as a requirement in the future (I like to learn and test stuff in the lab when I have spare time at work).  It would be used if the company changed namespace, for example, or was bought out.

If you have 2010 set up as webmail.domain.com and wanted to drop the webmail part and move to mail.domain.com (or even if the domain changed to webmail.newdomain.com) is this easy enough to accomplish?  Internal and external DNS are the same (ie webmail.domain.com is used internally and externally).

OWA, Activesync and ECP, etc run off the webmail.domain.com link so the virtual directories would need to be changed which is easy enough.  Where else would the change need to be applied as a lot of the settings configured are not in the console, but powershell only.

The list I can think of is:

1.OWA (2010 console under server config)
2.ECP (2010 console under server config)
3.Activesync (2010 console under server config)
4.OAB (2010 console under server config)
5. EWS (Powershell only)
6.Autodiscoverserviceinternaluri is Autodiscover.domain.com so no need to change
7.Outlook CAS array is Outlook.domain.com so no change required
8.DAG is on DAG01.domain.com so no need to change

Is the above list the only parts that would need changing, or are there more hidden settings somewhere?

Hi,

I have the same problem that someone reported here.

We have 2 UM servers with identical setups (UM config, certificates, etc) in different sites. One works perfectly. The other, you can call and configure your voice mail, call and leave a voice mail or be diverted to another number via a call answering rule.

All this works except the voice mail is not delivered. In the application event log I see:

A pipeline stage encountered the following error. Details : 'Microsoft.Exchange.Net.ExSmtpClient.TlsApiFailureException: A TLS API failure occurred. Error = 0x80090301

This is logged continuously, every minute or so, or more. If I set this UM server startup mode to only TCP, the events are not logged continuously and then only ocurr when someone tries to leave a voice message.

Both servers have UM assigned certificates with the correct subject/DNS names. The corresponding CAS servers have specific receive connectors, configured for TLS, for both the working and non-working UM server IP addresses. I have even loaded the UM certs onto our CAS servers. What-ever I try, the good server just works, and the bad one just logs this error.

Does anyone have any suggestions as to why this is?

Cheers,

Rob

Hi,

Having a problem with Outlook 2003 users viewing each other’s Free\Busy scheduler after they have been migrated.

My setup is as follows

• Running Exch 03 with Outlook 2003 clients, problem the same with cached & online profiles.  
• Have installed Exch 2010 SP2 Rollup4 into our Org.
• From Exch 03 replicated PF’s & System Folders to Exch 2010

What I have checked

• Made sure the PF is selected on the properties of the Exch 2010 databases
• Ran get-publicfolder -Identity "\NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY" -Recurse | fl name,Replicas and the result shows the Exch 2010 PF’s
• Ran the Outlook /cleanfreebusy command without errors
• Left for a few days encase it was slow replication

Any help would be great

Thanks

Hi,

I am looking for some detailed information on configuring loadgen 2010 for exch 2010.

Also our exchange servers are VMware guests. To performance mon the virtual exchange server while loadgen is running I presume I need to run he counters on the host?

Hi all,

I've come across a curious problem. Actually i have a multi-sites Active Directory infrastructure with an Exchange Organization.

On site A, i have two Exchange Server 2010 SP2 with MBX/HUB/CAS and Outlook Anywhere, there are member of a DAG.

On site B, i have one Exchange Server 2010 SP2 with MBX/HUB/CAS, Outlook Anywhere is desactivated, but still member of the same DAG that site A. Users from this site should be able to perform only autodiscover request via EXCH and WEB, not EXPR.

But i've noticed that EXPR requests are still performed by those users, and that the autodiscover proxy server for Exchange in Outlook 2010 is a server member of a third site on which i can't do something. Moreover, users who goes from site B to site A have connections issues, linked to the HTTPS configuration.

By now, i've corrected these settings with a GPO that forces the proxy server for Exchange in Outlook 2010.

But i would like to know why for local request on site B, users perform HTTPS request with EXPR instead of using RPC with EXCH, and how to correct the autodiscover configuration. Any idea?

Thanks.

Hello,

Hello,

We are currently having the following setup:

-         Parent domain: domain.com (Head Office),

child domain: sub.domain.com (Branch site)

-         Exchange 2007 and 2010 coexisted in the parent domain, currently in process of transitioning to 2010.

-         All the users in the sub.domain.com are having mailboxes in the Exchange 2007 in the Parent domain with SMTP domain name: @sub.domain.com.

1-     We need to install Exchange 2010 in the sub.domain.com, so that users will have their mailboxes in the sub domain, how to start it?

2-     And can we move the mailboxes from the parent to child domain. I need the best practice to do this.

3-     If we installed Exchange 2010 in the sub domain, and change the route for sub.domin.com SMTP traffic to the child Exchange server, how will exchange process the email if the mailbox still remains in the parent site? Do we need to create a send connector to forward the mails to the parent site if the mailbox still remains there?

4-     One more thing, the sub.domain.com users are having two e-mail address policies; the @sub.domain.com policy and the default policy which is @domain.com , I have tried to remove the second policy, but it is not editable.

Thanks in advance.

Hi,

I have an exchange 2003 (sp2) organization.

I want to migrate to exchange 2010.

My users are using actually: outlook clients (2003, 2007, 2010).

I want to verrify two things before dowing the migration:

• Do users having their mailbox being moved remain offline until the operation completes?
• After installing the new exchange server, do the outlook profiles need to be recreated using autodiscovery?
• Do the outlook clients uses the legacy url?

Thank you.

I have a server running exchange 2010. The other night we had a power failure and our exchange server has not worked since. At first the exchange store wouldn't start and outlook would not open on the client computers. However now that is fixed and outlook opens fine. All the messages are in the inbox and calendars work. I am not able to send or receive mail though. All the exchange services that I can tell need to be started are, I have also tried rebooting the server.

Any ideas on where I should start at?

Hello,

My company wants to upgrade from SBS/Exchange to 2008 R2 and Exchange 2010 to replace our SBS boxes.  I have seen a number of articles that address this, but none that involve my situation involving two SBS boxes. Our main office has two SBS 2003 R2 boxes, one that has Exchange loaded (mail.company.local), and one that acts as a file server (city.company.local).

I've read that I can join one the 2008 R2/Exchange 2010 to the mail.company.local domain and migrate, but that is a separate forest, and I want the main forest to be city.company.local and eliminate the mail.company.local domain or at least have it in the same forest.

My question is can I join a 2008 R2/Exchange 2010 box to the city.company.local domain and migrate the mail.company.local Exchange to that domain without the ability to establish a trust between the new server in city.company.local and the old SBS box? If not, how should I go about doing this migration and keep city.company.local as the forest?  Thanks in advance!

Exchange 2007 8.1 SP1 Migration to Exchange 2010 Stuck with "setup /Prepareschema" (May be caused by NO SP2 on 2007)

2 x DC2008R2 Domain Controllers

1 X SRV2003R2 with CAS 2007 SP1

1 x SRV2003R2 with CAS 2007 SP1 

1 x SRV2003R2 with Mailbox/Hub 2007 SP1

Running enviroment, Exchange 2007 all working. Mailflow OK.

Good evening,

I have a customer with a running Exchange 2007 SP1 8.1 (Build 240.6), enviroment. Sadly we did not check the SP Level of the Exchagnge itself which should be SP2 at least to upgrade to Exchange 2010 SP1. The customer has 1 x Mailbox/Hub and 2 x CAS Server running on 2003R2.

We did all complex pre tests but completely forgot to check the SP level of the Exchcnage 2007 itself.

The user we do this is Enterprise and Schema Admin.

Currently we are stuck with: setup /prepareschema which gives us following error. Should we:

1) Undo the LDIF Changes if we can (How?)

2) Install SP2 on the existing missing Exchange 2007 SP1 (3) and then redo the Setup /Prepareschema?

Thank you for any help

The following link http://technet.microsoft.com/en-us/library/bb125224(EXCHG.141).aspx states:

***
If you run the Exchange 2010 Setup wizard with an account that has the permissions required (Schema Admins, Domain Admins, and Enterprise Admins) to prepare Active Directory and the domain, the wizard will automatically prepare Active Directory and the domain. For more information, see Install Exchange Server 2010. However, if you're deploying a new Exchange organization, and you're preparing your Active Directory schema and domains using a computer running Windows Server 2008, you must first install the Active Directory management tools on the Windows Server 2008 computer prior to preparing the schema or domains. To do this, run the following command.
***

I am doing a fresh install with Exchange 2010 Standard with SP1 rolled in on a Server 2008 R2 domain member and NO previous exchange server.  Is the above stating I NEED to install AD Manangement tools first or is it only talking about older Windows Server 2008 as apposed to 2008 R2? 

Just want to be clear as to whether I have to manually do the preparation or will the setup wizard handle it automatically.

Thanks,
Greg

I use a a cvs file with this fields: Name,Alias,UserPrincipalName,Database,OrganzationalUnit,Password. The problem is that the OrganizationalUnit I want to put the users is Users - Company,Users - Test

When I use this command in EMC: Import-csv "c:\newusers.csv"| foreach {new-mailbox -name $_.name -alias $_.alias -userPrincipalName $_.UPN  - Database "First Storage Group\Mailbox Database" -Org Users -Password (ConvertTo-SecureString $_.password -AsPlainText -Force) }, the usermailboxen are made in Users. I have tried DB1,"OU,OU",DB1,{OU,OU}, etc. Can anyone tell me what the syntax must be?

Hi,

We are hosting several domain in our organization. I prefer to use a different IP for each domain to send emails. Or even I would like to be able to send bulk emails like newsletters and stuff like this through a different IP address and a different server name.

I know that I can set up a send connector on the edge server to use a specific IP address, but I wonder how I can instruct exchange to se use this connector for a particular sender or domain?

We have a recurring issue of DL owners being out sick/vacation etc when changes to the DL must be made. The results in calls to the help desk.

I see that we can add multiple individual owners from the Exchange Management Consolde, but we do not want to create confusion on who the "primary" owner of the DL is when someone looks at the DL properties from Outlook.

Is there a way to grant a group of users the right to add and remove members from a DL without making them appear as the DL owner?

Another option would be for the primary owner's name to always appear on the top of the list regardless of alphabetical order.
