Explanation
This warning message indicates a permissions problem. This may typically be seen in multiple domain scenarios where there are Exchange Servers in separate domains and a Site Connector links the two sites. The account specified in the Override tab of the Site Connector may not have Service Account Admin permissions on the Configuration and Site containers.

User Action
Examine the event description carefully. Ensure that the account listed in the Override tab has Service Account Admin permissions on the Site and Configuration containers on the other site.
