Solution to Fix Corrupted OST File and Convert Into PST Format

Though PST files act as the main storage repository of all the data stored in MS Outlook account, another file named OST contains the replica of all data stored in Exchange Server. The OST file comes into use when the user needs to work in offline mode. Once the OST file is connected to Exchange Server, file will synchronize itself with Server where any changes made during offline mode will be updated. In this content, we will be discussing about OST file, its corruptions issues, errors due to corruption, how to fix the OST file and convert it into PST format.

Issues Related to OST File 

The OST file is very much prone to issues that may lead to corruption or inaccessibility. Some of the issues are as follows:

Exceeding Size limit of OST file

The OST file has its own size limit set by different versions of MS Outlook. Maximum OST file size in UNICODE format is 20 GB for Outlook 2007 and it has been increased to 50 GB for MS Outlook 2010/2013. By default, the maximum size is set as 20 GB, which is why when the OST file reaches or exceeds this limit; errors will be encountered slowing down the performance of Outlook and may lead to corruption.

Synchronization Issues

The main reason behind inaccessibility lies on the synchronization issues of OST file. The OST file can only be accessed in the Outlook profile for which it was created. It is because OST file is encrypted and we need decryption key of the Outlook profile that needs to be matched with the one present in Exchange Server during synchronization. If the keys do not match, OST file will not be accessible.

Errors due to Corrupted OST Files

The corrupted OST files will interrupt the smooth functioning of Outlook and users may encounter errors when they try to access the OST file in MS Outlook. Some Errors are as follows:

1. When there is any synchronization issues in OST file with an Exchange Server, this type of error is generated as shown below. 
   
   
   
   
   
2. This type of error is generated when OST file is not able to synchronize with an Exchange Server. 





3. The third most common error is also shown when the OST file is corrupted due to synchronization issues.

Fixing Corrupted OST File & Convert into PST

There are several methods for fixing the corrupted or inaccessible OST file. They are as follows:

Manual Method

Outlook Users can use an inbuilt utility scanost.exe to repair OST files that was present until MS outlook 2010 version. After that, scanpst.exe has been used for repair of both OST and PST files. Though the method makes the corrupted OST to healthy one, it takes unnecessary time and data are not recovered completely.

Third Party Tool

Since the manual method cannot give desired results, users switch to third party tools like OST PST Convert. The tool can successfully recover all the data items like emails, calendars, contacts etc. into PST format keeping the original formatting of all items intact. The users can apply Mail Filter to export only the desired mails that are in and between the date ranges specified.

Conclusion: After discussing all the feasible method to recover data items from our OST file, we can conclude that Third party tool is better option as it maintains the data integrity after conversion. The inbuilt utility may help repair the OST file but it cannot recover data lost due to corruption as it removes the corrupted area only. It is important to keep our OST files healthy or uncorrupted. However, if it is corrupted, we recommend using the OST recovery Tool for complete data recovery from OST file.

How to Fix OST Synchronization Error 8004011D-526-80040115-0

Exchange Server user mailbox gets saved on local machine in the OST file. At both the ends, the data is continuously synchronized, i.e. any changes done at client or server end will be updated when there is frequent connection between both of them.

Any kind of breakage between both of them might lead to synchronization failure that generally affects the mailflow. If the emails are not properly synced between the client and the server, a user can get to know about through following procedure:

Open the OST file, right click on the mail folder that has to be checked for synchronization and click on “Properties”.

Click on the “Synchronization” tab and under it you will find “Statistics for this folder” option. Check out the fields and their values.

• Last Synchronized on: Date
• Server folder contains: No. of Items
• Offline folder contains: No. of Items

If the number of items on server and offline folder does not match, it means that emails are not synced properly. This is the manual method of testing if everything is updated on client or server end. However, there are times when a user is informed about the application about the abnormality in functioning. This is done through error messages like: “Synchronization Error 8004011D-526-80040115-0”.

This blog will explain this concept in detail and will also make you aware of possible solutions to fix orphaned OST file issues.

Why Orphan OST File Cannot Be Accessed?

Some of the situations have been explained above where there are chances of OST file getting orphaned which might give you a picture of reason behind the OST file inaccessibility. To be clearer, the most important factor for OST being accessible is availability of Exchange profile. This is because the Exchange local OST file which is created after enabling Outlook cached mode is bound to the MAPI profile it was created for. So the file can be only accessed in the system in which the authenticated configuration was done. When the configuration is done, an encrypted cookie is stored to the registry of the system with mailbox’s unique ID. So the initial connection with the Exchange profile is extremely important to be established in order to access OST file. In case it is not done, the OST file becomes orphan and one can face problems accessing this file needing to fix orphaned OST file issues to access this data.

An Effectual Tool To Convert Enormous OST File With Advanced Recovery Process

Microsoft Outlook is an emailing client that is deployed both as a stand-alone application as well as in collaboration with Exchange server to send and receive messages in a network confined up to some users. In this blog we will cover up the various file formats supported by Outlook. We will focus majorly on OST files, their corruption and also will introduce a tool to convert enormous OST file with advanced recovery process.

The main difference between Outlook, when used as a stand-alone application and when used in Exchange workstation, is the location and the type of file that stores the corresponding emails and messages. This is defined by the profile that is deployed by MS Outlook. MS Outlook when used without Exchange server stores the mails and data in PST file. In the case when Outlook is used in Exchange collaboration state the data is stored in an OST file. But similar to other file types, the OST file also tends to be unstable and can end up in getting corrupted.

Major Reason For OST Corruption

The biggest reason for the corruption of OST files is exceed in size of the OST file. The OST file is categorized into two sections based on the version of Outlook being used. The Outlook version 2002 and above employed ANSI type OST files and from Outlook version 2003 onwards the OST files have remained to be of UNICODE type. In ANSI type OST files the maximum size of the OST file was restricted to 2 GB. This implies that exceeding the file size above 2 GB would result in the ultimate corruption of the OST file. On the other hand the ANSI type OST file size was exceeded and limited to 20 GB. Due to exceed in the size of the OST file of any type, be it ANSI or UNICODE, leads to corruption of OST file. This is the most probable reason that enormous OST files tend to get corrupted soon.

Other Reasons Behind OST File Corruption

There are several reasons that play a crucial role in the corruption of OST files. Some of them are:

• Virus infection and malware may result in a totally corrupted OST file. The viruses penetrate deep inside the OST file and turn them into an inaccessible state.
• When Outlook terminates due to a power failure or power surge, the OST file can end up crashing. Also, when the user closes Outlook abruptly while it is undergoing through synchronization or some other operation, there are high chances that the OST file will get corrupted.
• The synchronization process between OST file and Exchange server may halt at some point of time, resulting in a corrupted or inaccessible OST file.
• When the OST file synchronizes with Exchange server certain issues in the network such as bad routers or hubs affects the synchronization process, ultimately leading to corrupt OST files.

The Solution!

As they say prevention is better than cure, the ultimate solution for the corruption of OST files is to avoid the files from getting corrupted at first place. But in case your OST files have already gone corrupted, there is no other way out except one. Deploy third party application for recovering the data within the corrupted OST file. One such solution is OST Recovery. It is no doubt, an efficient tool to convert enormous OST file with advanced recovery process. The tool recovers the data residing in the corrupted OST file and saves it in another healthy file say a PST file. Afterwards, the PST file can be easily accessed in Outlook for further usage.
