Privacy policy. Thank you. This cmdlet is available in on-premises Exchange and in the cloud-based service. Some parameters and settings may be exclusive to one environment or the other. For information about the parameter sets in the Syntax section below, see Exchange cmdlet syntax. You need to be assigned permissions before you can run this cmdlet.

Privacy policy. Because SMM operates without the operating system's knowledge or control, SMM represents a significant attack surface that could be leveraged by malicious code to compromise or circumvent the OS protections enabled through VBS. Delivering a robust and secure VBS platform requires careful scrutiny and likely updates of SMM code by the OEM to eliminate common vulnerabilities that may be exploited.

The WSMT contains flags which firmware can set to indicate to the operating system which of these specific security best practices have been implemented. Supported versions of the Windows operating system read the WSMT Protection Flags early during initialization, prior to hypervisor and VBS launch, and may elect to enable, disable, or de-feature certain security features based on the presence of these SMM Protections Flags. Rather, all SMM pointers must be validated to be within these safe memory regions.

For information about the parameter sets in the Syntax section below, see Exchange cmdlet syntax. The Set-SmimeConfig cmdlet can change several important parameters than can reduce the overall level of message security. Review your organization's security policy before you make any changes. You need to be assigned permissions before you can run this cmdlet. Although this topic lists all parameters for the cmdlet, you may not have access to some parameters if they're not included in the permissions assigned to you.

To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet.

The OWAAlwaysEncrypt parameter specifies whether all outgoing messages are automatically encrypted in Outlook on the web. Valid values are:. This setting affects the security and privacy of Outlook on the web.

Consult your organization's security policy before you change this setting. A valid value is an integer between 0 and UInt The default value is 60 seconds. When multiple CRLs in a certificate chain must be retrieved, the time limit that's specified by this parameter applies to each connection. For example, if a certificate requires the retrieval of three CRLs, and this parameter is set to 60 seconds , each individual CRL retrieval operation has a time limit of 60 seconds.

If any one of the CRLs isn't retrieved before the time limit expires, the entire operation fails. VA valid value is an integer between 0 and UInt The default value is 10 seconds. If all the required CRLs are not retrieved before the time limit expires, the operation fails. In this example, if any individual CRL retrieval takes more than 60 seconds, the operation fails.

Also, if all the CRL retrievals together take more than seconds, the operation fails. Disabling CRL checking can decrease the time that's required to validate the signatures of signed email messages, but it also validates email messages that are signed with revoked certificates.

The OWADLExpansionTimeout parameter specifies the time in milliseconds that Outlook on the web waits when sending encrypted messages to members of a distribution group that requires expansion.

If the operation doesn't complete in the time specified by this parameter, the operation fails and the message is not sent. When sending an encrypted message to a distribution group, Exchange expands the distribution group to retrieve the encryption certificate of each recipient.

While the distribution group is being expanded, the sender receives no response from Outlook on the web. The timeout value that's specified by this parameter is applied to the expansion of each distribution group.

For example, if an encrypted message is sent to three distribution group, and the value of this parameter is 60 seconds , the entire operation can take no more than seconds. The OWAEncryptionAlgorithms parameter specifies a list of symmetric encryption algorithms that are used by Outlook on the web to encrypt messages.
