When a Microsoft Exchange Server database is corrupt, it is directly reflected when you try to use or start Information Store service. Thus, if you are unable to start the service, one of the possible reasons can be database corruption. The further scenario illustrates one of such problems and then the possible MS Exchange Repair solutions to correct it.

Consider a case when you try to start Information Store service of Exchange Server and it doesn’t proceed as expected. In addition, you receive the below mentioned error message in system log or on screen:

“The Microsoft Exchange Information Store service terminated with service-specific error 4294966277.”

On examining the issue, when you view the Application Event log, the following entry is observed:

Event ID: 0
Source: ESE97
Type: Error
Category: Logging/Recovery

Description: MSExchangeIS ((451)) -1019

Event ID: 1120
Source: MSExchangeIS
Type Error
Category: General

Description: Error 0xfffffc05 initializing the Microsoft Exchange Server Information Store database.

The above symptoms indicate database corruption and thus when you run Eseutil repair utility, the following message is received:

“-1019 0xFFFFFC05 JET_errPageNotInitialized Repair Only: Read an unused page 4294966277”

Consequently, the corrupted database cannot be repaired.

Explanation

JET_errPageNotInitialized error typically indicates a blank page. But, if it occurs when starting the information store, this shows database page corruption. There can be several pages that cannot be initialized. So, Eseutil cannot repair this database.

Disable all anti-virus applications, file backup programs, and low-level access utilities
