You can't run the ESEUtil /p command to repair a database if a long value (LV) is corrupted in the database in Microsoft Exchange Server 2019 or Exchange Server 2016.
This issue occurs because the schema isn't loaded for the table hosting the LV tree.
To fix this issue, install one of the following updates:
For Exchange Server 2019, install the Cumulative Update 7 for Exchange Server 2019 or a later cumulative update for Exchange Server 2019.
For Exchange Server 2016, install the Cumulative Update 18 for Exchange Server 2016 or a later cumulative update for Exchange Server 2016.
