My indexes fail immediately after success, and each database reports the following error

The indexing of mailbox database MDB11 encountered an unexpected exception.

    Hi @Xiangtian Yang

    Do you have a DAG deployment or it is a standalone Exchange 2016 server?
    If it is a standalone server, I would recommend rebuilding the index and see if it can resolve this issue.

    Here are the steps:
    1.stop the "Microsoft Exchange Search Host Controller" and "Microsoft Exchange Search" services on the Exchange server
    2.locate the path of the databases (By default it would be C:\Program Files\Microsoft\Exchange Server\V15\Mailbox\<database name>
    3.delete the folder which has a guid name in the database folder

    4.start the "Microsoft Exchange Search Host Controller" and "Microsoft Exchange Search" services
    5.wait for the index to be rebuilt

    This method was tried and unsuccessful. I had three DAG nodes, I deleted one and it returned to normal
