Dear Microsoft, I've setup Outlook Anywhere for one of my client, the setting is working. FYI, the server name is "exchange.domain.com" and customer also have another host A record with mail.domain.com The Outlook Anywhere path is mail.domain.com, when the notebook plugged-in to network, the outlook anywhere url will showed as exchange.domain.com Please advise how to resolve it. Thank You.

Are you sure that you looking at the correct setting? The server name is shown in two places. 1. In the server address in the account settings, where it will always show the server name, even externally. 2. In the Outlook Anywhere box, where it will show the URL that you have configured in Outlook Anywhere settings in Exchange. You should verify what Autodiscover is handing out. Without Outlook 2007 or higher running, hold down CTRL while right clicking on the Outlook icon in the system tray. Choose Test Email AutoConfiguration. Run the test and see what addresses are being returned and verify they match what you expect. Simon.Simon Butler, Exchange MVP Blog | Exchange Resources | In the UK? Hire Me.

The server name in your account should be the internal name, with the outlook anywhere settings using the external name.

Hello, Here is the internal mailbox server name: And this is the OA proxy server name: You can use Get-OutlookAnywhere |FL to see the proxy server name. Thanks, Simon

Hi Simon Butter, John & Simon Wu, As illustrated on the setting above, when the notebook connected to LAN, the "proxyserver.exchange.com" willl immediately change to "mbx.exchange.com". Any idea why the Outlook Anywhere address will change when it plugged in to LAN? Thus, when the notebook user go out again and connect via Outlook Anywhere, it can't be connect due to end user do not know the setting. I can provide the snapshots to you, kindly provide me email or anything for me to upload. Thank You.

@smartetchsupport Are you sure there is no GPO being applied on machine changing this setting? Check your GPO's. Sukh

Hi Sukh, Checked, there is no GPO applied for changing this setting. One thing that I can confirmed is:- The DNS Server contains two Host A record for exchange server name which is exchange.domain.com & mail.domain.com Outlook Anywhere set as mail.domain.com Once mobile user(notebook user) come in to office, when it plug the LAN port, immediately Outlook Anywhere url has changed to exchange.domain.com Thank You.

1. Which version of Outlook clients are you using? 2. Oulook 2007/2010 will use the SCP object to connect using the URL's which will take them to your CAS server. (http://technet.microsoft.com/en-us/library/bb124251.aspx) 3. Verify your SCP Url's (Get-ClientAccessServer | fl > C:\cas.txt) 4. Check the following key HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\AutoDiscover on a clent computer and see if any predefined autodiscover URL is specified. Sukh

Hi Sherrie, It’s a Outlook provider issue. Try the following commands in EMS: Set-Outlookprovider -Identity EXPR -Certprincipalname $null Set-OutlookProvider -Identity EXPR -Server $null Thanks, Simon

Hi Sukh, Outlook 2010 Noted here is the result, see below ame : EXCHANGE OutlookAnywhereEnabled : True AutoDiscoverServiceCN : Exchange AutoDiscoverServiceClassName : ms-Exchange-AutoDiscover-Service AutoDiscoverServiceInternalUri : https://exchange.domain.com/Autodiscover/Autodi scover.xml AutoDiscoverServiceGuid : 77378f46-2c66-4aa9-a6a6-3e7a48b19596 AutoDiscoverSiteScope : {Default-First-Site-Name} IsValid : True OriginatingServer : DC01.domain.com ExchangeVersion : 0.1 (8.0.535.0) DistinguishedName : CN=EXCHANGE,CN=Servers,CN=Exchange Administrat ive Group (FYDIBOHF23SPDLT),CN=Administrative Groups,CN=ICLIF,CN=Microsoft Exchange,CN=Servi ces,CN=Configuration,DC=domain,DC=com Identity : EXCHANGE Guid : cb813056-2904-4dbb-b0df-c9012cefde89 ObjectCategory : domain.com/Configuration/Schema/ms-Exch-Exchang e-Server ObjectClass : {top, server, msExchExchangeServer} WhenChanged : 8/12/2010 3:45:29 PM WhenCreated : 3/11/2008 1:55:59 PM Name : EX01 OutlookAnywhereEnabled : False AutoDiscoverServiceCN : EX01 AutoDiscoverServiceClassName : ms-Exchange-AutoDiscover-Service AutoDiscoverServiceInternalUri : https://ex01.domain.com/Autodiscover/Autodiscov er.xml AutoDiscoverServiceGuid : 77378f46-2c66-4aa9-a6a6-3e7a48b19596 AutoDiscoverSiteScope : {Default-First-Site-Name} IsValid : True OriginatingServer : DC01.domain.com ExchangeVersion : 0.1 (8.0.535.0) DistinguishedName : CN=EX01,CN=Servers,CN=Exchange Administrative Group (FYDIBOHF23SPDLT),CN=Administrative Grou ps,CN=domain,CN=Microsoft Exchange,CN=Services, CN=Configuration,DC=domain,DC=com Identity : EX01 Guid : d01b93f8-b14d-4de9-967d-e48f408f9a4d ObjectCategory : domain.com/Configuration/Schema/ms-Exch-Exchang e-Server ObjectClass : {top, server, msExchExchangeServer} WhenChanged : 5/4/2011 6:00:32 PM WhenCreated : 5/4/2011 5:20:15 PM ## However, Outlook Anywhere has been enabled. 4. I cannot get hold of any notebook but few notebooks now having this problem, so i don't think is client's problem.

Hi Simon, My name is Stanley, not Sherrie. You mean by running these command on EMS, it will solve my problem? You can verify the above info. Thank You.

Just to add-on. DC01 = Windows Server 2008 R2 (Domain Controller) who hold FSMO role. EXCHANGE.DOMAIN.COM - Exchange 2007 server EX01.DOMAIN.COM - Exchange 2010 server just added 5/5/2011 for migration purpose.

@smarttectsupport. 1. Use the Get-Outlookprovider to see the values of the autodiscoverconfig. See if they are set, to what your are experiencing. If they are, then use the command Simon has suggested. The outout you posted above wont show this. Sukh

Dear Sukh, Thank You for your reply, here is the result. Get-OutlookProvider Name Server CertPrincipalName TTL ---- ------ ----------------- --- EXCH exchange.domain.com 1 EXPR exchange.domain.com 1 WEB exchange.domain.com 1 I defined mail.domain.com as my outlook anywhere address Well, so should I run Simon's command now?

Yes. Change the EXPR. Post back results. Sukh

Dear Sukh, Before I run the command, just want to verify if I do not have autodiscover Host A record on External & Internal DNS, will it caused any problem? If I run the comamnd before, will it affect any login problem via MAPI? Thank You Set-Outlookprovider -Identity EXPR -Certprincipalname $null Set-OutlookProvider -Identity EXPR -Server $null

1. No. Autodiscover will use various methods to connect. Leave the external host record. 2. Won't effect login via MAPI. Sukh

Here is the result on Get-OutlookProvider after applied the above Name Server CertPrincipalName TTL ---- ------ ----------------- --- EXCH exchange.domain.com 1 EXPR null 1 WEB exchange.domain.com 1 Please advise. Thank You.

Have you tested? Might take some to take effect.

I've run the command, as for notebook user, I only able to know the answer by next Monday.

@Smarttech Nice to know it worked :-) Sukh
