MSExchange Message Security

Alert Type


Rule Path

Microsoft Exchange Server/Exchange 2010/Edge Transport/Message Security

Rule Name

No valid TLS certificate was found. Exchange can't update the Active Directory Lightweight Directory Service (ADLDS) credentials.


This Error event indicates that a valid Transport Layer Security (TLS) certificate was not found on the server on which this event occurs. A TLS certificate is required for a Hub Transport server to use and update the EdgeSync replication account credentials.

User Action

To resolve this error, use one or more of the following methods:

  • Create a new TLS certificate for the server, and then resubscribe the Edge Transport server. You do not have to remove the Edge Subscription to resubscribe. To overwrite the existing Edge Subscription, run the New-EdgeSubscription cmdlet in the Exchange Management Shell on both the Edge Transport server and the Hub Transport server. For more information, see New-EdgeSubscription

  • Review the Application log and System log on your Exchange 2010 servers for related events. For example, events that occur immediately before and after this event may provide more information about the root cause of this error.

  • Review the Operations Console in Operations Manager for detailed information about the cause of this alert. For more information, see the "Introduction" section in this topic.

  • Resolve your issue by using self-support options, assisted support options, and other resources. You can access these resources from the Exchange Server Solutions Center. From this page, click Self-Support Options in the navigation pane to use self-help options. Self-help options include searching the Microsoft Knowledge Base, posting a question at the Exchange Server forums, and others. Alternatively, in the navigation pane, you can click Assisted Support Options to contact a Microsoft support professional. Because your organization may have a specific procedure for directly contacting Microsoft Technical Support, be sure to review your organization's guidelines first.
