Solution

• If the Enterprise Vault Storage Service is not running, start it, then check the review page to see if the item can be previewed.
• If the service is running, restart the Enterprise Vault Storage Service on the EV server to attempt to clear any stuck processes from memory, then check the review page to see if the item can be previewed.
• If restarting the service does not resolve the issue, restart the EV server to clear any stuck processes from memory and to reregister in the EnterpriseVaultDirectory database.
