VSE 8.8 does not cause this issue. Microsoft has indicated that correcting the Autodiscover provisioning alleviates this problem.
McAfee can't provide advice about how to configure Exchange Autodiscover. You must contact Microsoft Technical Support for assistance to identify the cause of the excessive wait time consumed by Microsoft
MSO.DLL. McAfee recommends that you obtain a Windows Performance Recorder Trace of the node to verify that the issue is related to wait time being consumed by Microsoft
MSO.DLL. If it does
not, contact McAfee Technical Support using the details provided in the Related Information section below.
