Cause

This issue occurs because the referenced transaction log in the E07.chk file has increased beyond the log files that are required in the header file of the Exchange database.

Resolution

Before you can resolve this issue, you must verify that you have this specific issue and that all transaction log files that are required by the database are present and readable. To do this, follow these steps:
  1. Open a command prompt and dump the database header by using the following command: 
    Eseutil /mh <path to .edb file>
    This command shows you that the database is in a "Dirty Shutdown" state. The database requires the transaction log files that resemble the following: 27974-27994 (0x6d46-0x6d5a)

    Note The transaction log numbers and names are only examples. Your transaction log numbers and names will differ.
  2. Obtain a dump header of the E07.chk file by using the following command:
    ESEUTIL /MK <Path to E07.chk>

    The output of this command resembles the following :

    Note In this case, the header of the checkpoint file is located in the 0x6D5A (Decimal=27994)transaction log file.
  3. Verify that all transaction logs required by the .edb database are present and readable. To do this, follow these steps:
    1. Open a command prompt in the directory that contains the transaction log files for the storage group.
    2. Use the following command to dump the sequence of transaction logs in this directory. 
      Eseutil /ml E0X

      Note This command verifies that all transaction logs are readable and that there are no gaps in the sequence of log files.
    3. In this case, you see the output resembles the following:

No damaged log files were found.

Operation completed successfully in 0.578 seconds.

      Note Make sure that all log files that are required by the database are present in the transaction log file directory.
  4. After you do this, rename the .chk file to E07.chk.old and then mount the database again. Therefore, the database ignores the .chk file and reads all required log files into itself.
