WORKAROUND
None.
Currently as per the release notes, the AD & Exchange agents would mandatorily require either Domain admin or Local admin privileges to successfully collect data. In either case if the privileges are revoked the agents would break and hence not collect data.
STATUS
Enhancement request number FVE-I-133 has been submitted to development for consideration in a future release of Foglight for AD and Foglight for Exchange, where the agents can be configured to collect data without Domain / Local admin rights.
