Public folder store and Mailbox store are the components of Exchange store. These stores further contain different files in them. In mailbox store, the files are priv.edb, priv.stm and in public folder store, the files are pub.edb and pub.stm. Both these Exchange store components are vulnerable to corruption and their corruption can stop the working of Exchange store service, which can lead to complete inaccessibility of Exchange Server database. To get over the corruption of mailbox store and public folder files, you can run an utility known as 'eseutil/p'. However, in some cases, this utility does not prove helpful to repair damaged database. For such cases, the last solution is a third party Exchange Server recovery tool.
Suppose, you use MS-Exchange database of around 300 GB. The Priv.edb file of your Exchange Server database has got corrupted and you executed the 'eseutil/p' command to resolve the issue. The repairing process by 'eseutil/p' command proceeded successfully, but suddenly stopped with an error message. The error message can be written as below:
“Assertion Failed: dPercentage >=0, file G:\ese97\src\eseutil\edbutil.cxx, line 563.”
Repair process remained incomplete and the data of Microsoft Exchange database became totally inaccessible. After that, the above error message appears every time you try to repair the Exchange database.
Why the error is coming?
The cause, that is responsible for the above stated error message is the corruption of priv.edb file and 'eseutil/p' utility falls short to solve the problem of corruption.
How the error can be solved?
For resolving above error message and to make the data of Exchange Server accessible, You have to follow the below suggestions:
- Use the latest or highest service pack level for Exchange Server 5.5.
- If, the problem still remains the same, you can use an up-to-date backup to restore the database.
If backup is deficient to restore the data or is not available, then you need to go for a third party Exchange Server Recovery product. Such third party Exchange recovery software easily solves the problem of corruption and makes the Exchange Server database accessible. These tools are very simple and even can be used by a person from a non-technical background. You need not have to possess knowledge about Exchange server and once you use the tool, it provides detailed instruction to perform the repair operation.
