| Description | Information Store (3368) The log signature of the existing logfile E00.log doesnt match the logfiles from the backup set. Logfile replay cannot succeed unless all signatures match. |
| Event Information | According to Microsoft: CAUSE: This issue may occur if the Exchange Information Store service (Store.exe) is not running when you restore a full online backup of an Exchange Server 2003 computer. The restore process tries to replay the transaction log files, but because the Exchange Information Store service is not running, this prevents the information store databases from mounting. |
