Solution/Workaround/Procedure

The Exchange eseutil command can be used to check the consistency of logs of database:

Example; 'eseutil.exe /k '.
For example if logs of database with prefix E01 are located at c:\logs, then the command to be used is 'eseutil.exe /k "c:\logs\E01"'

Outcome;
The result within eseutil is;

Found Error: Access to source database 'z:\Exchange Server\V14\Mailbox\Public

Folders\E03' failed with Jet error -1811.

Missing log files: z:\Exchange Server\V14\Mailbox\Public Folders\E03{0000232B - 00002468}.log

Solution;
The problem is with the database/logs itself. The customer needs to approach Microsoft for this Exchange Database issue. The Netvault Exchange Server plugin merely uses eseutil.exe for checking consistency.
