Reasons behind EDB file errors and their prospective solution Arlen Pledge . 19th Jul 2016 . 1 Reply

Since the release of version 4.0 in 1996, Microsoft Exchange Server has seen several technological changes and has proved itself the best amongst its competitors. However, its vulnerable nature couldn’t be changed till now. EDB file corruption is the most common issue shared by all MS Exchange Server users across the globe. For understanding the whole concept of EDB file corruption, we must understand the purpose of the EDB files.

EDB is one of the key file format maintained by Exchange Server. EDB files preserve and store user’s mailbox information on the Exchange Server. Just like other mailboxes it carries mail components like emails, Calendar, Notes, Contacts, appointments etc. These mailbox components can get formatted or corrupted due to various hardware issues, making complete mailbox inaccessible. Whereas, several software issues can also turn EDB files corrupt stopping all the Exchange Server transactions at once. Some of the issues causing EDB corruption have been described below:

  • Overloaded EDB file due to multiple users

  • Interruption in power supply causing abrupt system shutdown

  • Accidental removal of mailbox or one of its components

  • Jet Engine Transaction causing series of errors

  • EDB data loss caused by header corruption or formatting

  • Usage of malicious software affecting integrity of residing EDB files on the system

  • Corruption of associated hard drive in which EDB backup files reside

  • Corruption of any associated software affecting EDB file

Apart from these issues, many other issues result in EDB file error. These issues cause following errors:

1.Jet engine error 1018

This error generally occurs when the header value differs from the resultant value during an event. It also occurs due to error in NTFS file system or when the corrupt data is assigned to unidentified location.

2.Jet engine error 1019

This error occurs due to invalid logical links and pointers among pages. The associated applications or Exchange Server issues cause it. It generally shows up when uninitialized page found to be in use.

3.Jet engine error 1022

This error is caused by corrupted EDB file. It occurs due to misinterpretation of number of log file pages. This error prevent user from accessing any other EDB files too.

Prospective solution of the errors

Although Eseutil and Isinteg are availed by MS Exchange Server to resolve, linked issues and errors but these two inbuilt utilities have some limitations. They often fail to resolve rigorous errors even after several attempts. Therefore, experts suggest obtaining certified EDB to PST converter software, which is capable of solving all the problems associated with MS Exchange Server versions. It is always safe to test the software’s features before paying a hefty amount for its license. Utilize Kernel for Exchange Server recovery software, popular third party software possessing all the capable features of perfect EDB recovery software. It not only removes errors from the required files but also permits user to manage them efficiently. It lists the recovered files components in sequence, so that user can select and preview them easily, before taking any saving step. User can even migrate the recovered files to Office 365, Live Exchange Server, Archive mailboxes, Private folders etc for safekeeping it form further damage. Get an idea about the software by downloading its free version. Checkout more info visit at: http://www.exchangerecoverytools.org/

Email services are core component of any Exchange organization. When Exchange Server services are halted due to any reason, all the other services associated with it stop responding. In such a case some user would go through panic state and some would look up to the backup the files and folders for rescue. But restoring backup files may not be the best solution always. The most important thing to do in such crises situation is to resume the flow of mails as quick as possible, because restoration of entire Exchange database can be time consuming. So it is advised to restore mail services first and then get back the remaining database subsequently. Here we have outlined four easy ways using which user can easily restore mail services rapidly:

1. Recognize and Rebuild the infrastructure of Corrupt Exchange Server:

Step1: Check the Active directory to identify the failed Server.
Step2: Open the directory then reset the account of the computer associated with the corrupted Server.
Step3: Install on the failed Server
Setp4: Modify the name of the computer in order to keep it identical with the name of the failed server.
Step5: Now, connect the server to the domain.
Step6: Add the Exchange Server installation media in the server.
Step7: Click Run and write this command: Setup.com /M:RecoverServer

2. Using Dial Tone Recovery Method:

Step1: Form a new database by running this dial tone recovery command: New-Mailbox Database --Name Dialtone --EdbFilePath D:DialtoneDialTone.edb (Note: Build the database in a free space)
Step2: Type Get-Mailbox command to restore the list of the mailboxes carried by the corrupted Server.  
Step3: Use Set-Mailbox cmdlet to restore the mailboxes.
Step4: Now, mount the database using Mount-Database cmdlet: Mount-Database --Identity Dialtone

3. Recover Old data from Exchange Server:

Step1: Go to the recovery storage group to restore your backup.
Step2: Merge your recovery storage group with the data that has been collected in the dial tone database.

Recover the data through third party recovery tool:

The above three ways are outlined when a single Exchange Server is corrupted. But they would be of no help when the database is severely corrupted or multiple Exchange database files are corrupted. You can take the help of a third party EDB to PST Converter tool to get your database back. Download Kernel for Exchange Server recovery software, a prominent third party Exchange database recovery tool and resume your work flow in a short span of time. The software is embedded with advanced Exchange recovery features, so you can modify the recovered database according your requirements. You can also use this tool to export your recovered database files to Live Exchange Server or to Office 365 mailbox. http://www.exchangedatabaserecovery.edbtopstfile.net/

Eseutil is an inbuilt device in MS Exchange Server that assists users with repairing the corrupted EDB file or Exchange database. Despite the fact that it is exceptionally valuable, in any case you will lose some information while utilizing it to repair EDB files (Exchange database). The Eseutil does not repair the corrupted database in genuine, indeed it remakes the database and erases the invalid information which are recognized amid the rebuild process.

Isinteg – To repair exchange server

Another inbuilt utility in Exchange Server is Isinteg that assists users with performing a search through an offline data store for integrity weaknesses. The issues and mistakes which are detected by the Isintig, can easily fixed by by utilizing it. To run Isinteg.exe,  you need to go to the command prompt.

Before utilizing the Eseutil and Isinteg tool, you have to perform a few activities which are given  below:

Creating of replica of a exchange server database: You have to make a replica of the corrupted database to repair EDB files. On the off chance that you are not certain about the database's location database files or the names of the files, you can take assistance from the Exchange Server Manager. By getting to the database properties from the Exchange Server Manager, you can find the files. You will be diverted to the database page where you will find a listing of file names and paths.

Before performing the repairing activity, verify the database file you are going to repair is legitimately properly dismounted. To check it, open the Exchange Management Console (EMC) on your system and navigate to the Organization Configuration. Click on Mailbox, and after that pick the Database Management tab. In this tab, you can see every one of the databases in your Exchange organization. The database file you are going to repair, is likewise there. Verify the document is dismounted when you find in the Mounted section. On the off chance that the file is mounted, just right-tap on the information and select the Dismount Database command.

Confirmation of disk space: This is the last activity in which you have to affirm the disk space to perform the repair task. Verify you have the empty space of no less than 20% of the aggregate database size.

Easily run Eseutil from the command prompt?

    Go to Start > Run or simply press Win+R.
    Now in the run box, type “cmd” and press OK.

Acquaintance of Exchange Server database Error 1018 Henri Walgor . 15th Oct 2015 . 1 Reply

Error 1018 usually occurs because of the following reasons:


Checksum value of page in with header isn't going to match up the worth re-calculated though any kind of function is carried out with ESE databases.


There is certainly either a number of miscalculation together with NTFS report program or maybe the results is it being published with an completely wrong location within the hard disk.


The Exchange Server at times acts wary itself and generates this error. This happens when the server generates an incorrect checksum value for the page.


The Exchange Server from time to time works careful itself along with builds that mistake. This kind of takes place when the server builds a completely wrong checksum value for the page.


Fixing the Exchange Error 1018

Eliminating errors are the most common term that system professionals often come across. The main focus of the user is to meet the minimal essential criteria which is required to relieve the system-in-use. Being the most common strategy, it is widely accepted and even highly recommended. The same strategy in used in eliminating the error 450 in exchange server.

Exchange servers are prone to binary mishaps, known as errors, which most often tend to affect the exchange server files and their execution upon any command from user system. Any alien command or disproportion of hardware utility may lead to serious damages to the exchange server files.

Exchange Server Error 450-Aboriginal server error

Exchange server error 450, when displayed, indicates a serious issue with rejection of email by the exchange server. This error is witnessed with some domains, while other domains does not display error messages.

450 4.7.1 Client host rejected: cannot find your reverse hostname

This error implies that the concerned server is keen to verify the address with which user has sent an email. Usually, when sender sends the email, the email reaches to the server, which in turn verifies the IP address from where it is coming from. If the server produces a failure report of mail failure, then error is simultaneously generated. This error is also faced when the recipient address is not valid and access to the server is not valid.

450 4.7.1 Recipient address rejected: Access denied

Resolutions for Exchange Server Error 450

The consequence of error 450 is very well known to the system administrators. However, the solution to such problem must also be known to the user as it may act as smart remedy to get rid of the tingling issue.

  • Check Reverse DNS: Sometimes The Reverse DNS is linked to an Internet Service Provider, which must actually be linked to Fully Qualified Domain Name (FQDN). Therefore, error 450 is caused. The user must ensure that domain name is not invalid and must create a valid setup.
  • Check Blacklisted IP Addresses: If your email id is blacklisted, then server will never identify your email id and it will reflect the commands back to the user who has initiated the mails.

The above mentioned resolutions may somehow assist you in rescuing EDB and STM file but in case where severe file corruption is involved, user must take assistance from a reliable third-party tool like Kernel for Exchange Server.

Executing common chores with Kernel for Exchange Server
