The Event Log on our Exchange 2007 Server is regularly throwing up the following warning message
Event Type: Warning
Event Source: MSExchange ADAccess
Event Category: Validation
Event ID: 2161
Process edgetransport.exe (Transport) (PID=4424). Object CN=QGSL,CN=Folder Hierarchies,CN=First Administrative Group,CN=Administrative Groups,CN=QGSL,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=QuestPBC,DC=quest,DC=com read from exch1.QuestPBC.quest.com failed validation. Attribute: PublicFolderTreeType. Error message: The value of property 'PublicFolderTreeType', 0, is not defined in the Enum type 'PublicFolderTreeType'.. Invalid data: 0.
Can someone tell why this is happening and how I can stop it from doing it.
I have been told that we used to have an old Exchange 2K3 that has been uninstalled.
