Rule Name

The provider configuration for the Autodiscover service is not valid. To obtain a valid DLL, contact Microsoft Product Support.


This Warning event indicates that an invalid attribute was registered by the provider DLL with the Microsoft Exchange Autodiscover service on the Exchange Client Access server. When a provider registers with the Autodiscover service, the provider must declare certain attributes such as a GUID, request schema, and response schema. If the provider file has specified an invalid attribute to the Autodiscover service, the event is logged.

GUIDs identify objects such as interfaces, manager entry-point vectors (EPVs), and class objects. A GUID is a 128-bit value that consists of one group of 8 hexadecimal digits, followed by three groups of 4 hexadecimal digits each, and followed by one group of 12 hexadecimal digits. The following sample GUID shows the groupings of hexadecimal digits in a GUID: 6B29FC40-CA47-1067-B31D-00DD010662DA.

User Action

To resolve this warning, take one or more of the following steps:

  • Look at the Application log for a detailed description of the event.
