Applies to: Exchange Server 2016

This cmdlet is available only in on-premises Exchange Server 2016.

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

For information about the parameter sets in the Syntax section below, see Syntax.

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

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

Set-OutlookProvider -Identity msExchAutoDiscoverConfig -TTL 2

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 Clients and mobile devices permissions topic.


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 specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.

  • Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax: -Confirm:$false.

  • Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.




The DomainController parameter specifies the domain controller that's used by this cmdlet to read data from or write data to Active Directory. You identify the domain controller by its fully qualified domain name (FQDN). For example, dc01.contoso.com.




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 how Outlook clients should connect to the Exchange server. The value can be set to ServerExclusiveConnect, ExternalClientsRequireSSL, InternalClientsRequireSSL, or to None to clear the flags. The recommended value is None, which is also the default setting.




The RequiredClientVersions parameter specifies the minimum version of Microsoft Outlook that's allowed to connect to the Exchange server. This information is in the Autodiscover response to the client connection request. Valid input for this parameter is "<MinimumVersion>, <ExpirationDate>".

<MinimumVersion> is the version of Outlook in the format xx.x.xxxx.xxxx. For example, to specify Outlook 2010 Service Pack 2 (SP2), use the value 14.0.7012.1000.

<ExpirationDate> is the UTC date-time when connections by older versions of Outlook will be blocked. The UTC date-time is represented in the ISO 8601 date-time format: yyyy-mm-ddThh:mm:ss.fffZ, where yyyy = year, mm = month, dd = day, T indicates the beginning of the time component, hh = hour, mm = minute, ss = second, fff = fractions of a second, and Z signifies Zulu, which is another way to denote UTC.

An example of a valid value for this parameter is "14.0.7012.1000, 2014-01-01T12:00:00Z".




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 simulates the actions of the command. You can use this switch to view the changes that would occur without actually applying those changes. You don't need to specify a value with this switch.
