In Microsoft Exchange Server, you can perform hard recovery to retrieve missing or inaccessible data. Such recovery is performed after restoration from online backup, in case of serious database corruption. Hard recovery is the process of replaying a log file, which is similar to the soft recovery. In some cases, the hard recovery can not be completed successfully and the database remains inaccessible and unusable. At this point, you need to go for Exchange Server Recovery to get your mission critical and precious data back.

In a practical scenario, when you attempt to carry out the hard recovery of Microsoft Exchange Server, you might come across -1019 error message. After this error message, you may find the following Event IDs in Application Event Log of Microsoft Exchange Server:

Event ID: 0 Source: ESE97 Type: Error Category: Performance Description: (252) Unexpected Win32 error: 0×3E6
