I have a cluster deployment with one search cluster and one indexer cluster. Recently I upgraded MS Exchange App to the search cluster: Upgraded windows_TA from 5.0.1 to 7.0.0 Upgraded Exchange TAs from 3.5.1 to 4.0.1 Upgraded Exchange App from 3.5.1 to 4.0.1 Removed windows infrastructure app 1.5.1 The TAs are also pushed to the indexer cluster. I also have removed the windows_apps.csv lookup under Exchange app as there is a newer copy under windows_TA, which suppressed "Could not load lookup=LOOKUP-app4_for_windows_security" error. I did not change anything else to the App. However, every indexer reports  “Could not load lookup=LOOKUP-user_account_control_property “ error for any searches. The user_account_control_property lookup come with the Windows_TA and is readable by any user/app by default. Could somebody help? Thanks in advance!     ... View more
