Use the Set-OutlookProvider cmdlet to set specific global settings using the msExchOutlookProvider attribute on the msExchAutoDiscoverConfig object in Active Directory.

Set-OutlookProvider -Identity <OutlookProviderIdParameter> [-CertPrincipalName <String>] [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-Name <String>] [-OutlookProviderFlags <None | ServerExclusiveConnect>] [-Server <String>] [-TTL <Int32>] [-WhatIf [<SwitchParameter>]]

Parameter Required Type Description




The Identity parameter specifies the ADIDParameter value of the MAPI protocol for which you want to set global settings.




The CertPrincipalName parameter specifies the Secure Sockets Layer (SSL) certificate principal name required for connecting to Exchange from an external location.

This parameter is only used for Outlook Anywhere clients.




The Confirm switch causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm switch.




The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory.




The Name parameter specifies a common name for the Outlook Provider Configuration object. This can be a user-friendly name for identification.




The OutlookProviderFlags parameter specifies that Outlook 2010 clients should connect using RPC over HTTP (Outlook Anywhere) before trying RPC over TCP connections. This increases the speed at which Outlook 2010 clients will connect when clients are primarily accessing Exchange over the Internet. The value can be set to ServerExclusiveConnect or to None to clear the flags. For Outlook 2010 clients that access Exchange over both organization intranets and the Internet, the recommended value is None, which is also the default setting.




The Server parameter specifies the Mailbox server to use for Outlook Anywhere clients.




The TTL parameter specifies the duration (in hours) that the specified settings are valid.

If a value is specified, the settings are rediscovered via the Autodiscover service after the duration specified with this parameter. A value of 0 indicates that no rediscovery is required. The default value is 1 hour.




The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf switch.

The Set-OutlookProvider cmdlet creates the global settings for the Autodiscover service. It sets the AutoDiscoverConfig object under the Global Settings object in Active Directory and sets the attributes specified in the parameters listed in the Parameters section.

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Autodiscover service configuration settings" entry in the Client Access Permissions topic.

Error Description



Exceptions Description



This example changes the duration that the Autodiscover service settings are valid for the Microsoft Outlook provider msExchAutoDiscoverConfig.

Set-OutlookProvider -Identity msExchAutoDiscoverConfig -TTL 2

This example causes Outlook 2010 clients to connect exclusively through RPC over HTTP (Outlook Anywhere) before trying RPC over TCP connections when connecting over the Internet.

Set-OutlookProvider EXPR -OutlookProviderFlags:ServerExclusiveConnect

This example makes a change to the global settings for the Autodiscover service attribute in Active Directory. The change clears the flags that cause Outlook clients to connect exclusively through RPC over HTTP (Outlook Anywhere) before trying RPC over TCP connections when connecting over the Internet.

Set-OutlookProvider EXPR -OutlookProviderFlags:None
