Consult the event log on the server for other "ExchangeStoreDb" and "MSExchange Search Indexer" events for more specific information about the failure. Reseeding the catalog is recommended via the 'Update-MailboxDatabaseCopy' task.
Note:
If the mailbox database copy is the only copy, Exchange Search must create a new content index catalog. You can use the ResetSearchIndex.ps1 script to do this.
