Why We Need To Convert OST Files To Outlook PST?



Most of the users of MS Outlook are quite aware of two types of file formats i.e. OST and PST files. PST files (Personal Storage Table) are the main storehouse of all the data stored in Outlook whereas OST files (Offline Storage Table) contains the replica of data stored in Exchange server. OST comes into existence when the cached mode is enabled from Outlook allowing user to work offline without Mail server. Any changes made will get itself synchronized when connected with the Exchange Server. The blog will be discussing the reasons why we need to convert OST files to Outlook PST file.

Need of Conversion from OST to PST

The main reason why users prefer to convert their Exchange OST mailbox to PST file is the several issues of OST file that makes the OST file inaccessible or corrupted. Some of the causes that lead to the conversion of OST to PST file are as follows:
  • Issue of Exceeding OST Size Limit
    Size limit of OST file varies with different Outlook versions. In Outlook 2007, size limit supported was 20 GB, which was increased to 50 GB in 2010/2013 versions. Usually, the maximum default size limit is set to 20 GB, which is why performance of Outlook slows down when it reaches or exceeds this size limit.
  • Orphaned State of OST file
    Each OST file is bound to particular Exchange Mailbox and any modification made is continuously synchronized to Exchange Server. When the Exchange Mailbox is dismounted/deleted from the server, the OST file will become inaccessible leading to orphaned state.
  • Synchronization Problems
    It arises if there is any interruption while the OST file is being synchronized with the Exchange Server. Since the OST file is encrypted, decryption key of the Outlook profile needs to be matched with the one in Exchange Server. If it does not, OST file will face synchronization problem making file inaccessible.
  • OST Bound to MAPI Profile
    Since OST file is bound to a particular MAPI profile, its access can be only done when the user log in and authenticate using the profile that was originally used to create an OST file. In case of authentication failure, client will restrict user to open Exchange OST file and its contents.
  • Corrupted OST File
    OST file may be corrupted due to power failure during synchronization, virus attack, improper handling of OST file, damaged hard drive/local storage where the OST file was stored, etc. The OST file in corrupted state may lead to inaccessibility and loss of contents in it.

How to Convert OST to PST

As discussed above, the issues in OST file makes the conversion of OST to PST file necessary. However, Outlook does not support direct conversion of OST to PST file. To repair the damaged OST, an inbuilt utility scanost.exe can be used, which is now replaced by scanpst.exe for repair of both OST and PST files. This method is used only to repair slightly damaged OST file and does not convert OST to PST. Therefore, a reliable way for easy conversion of OST to PST file is possible with the help of a third party tool, OST to PST Converter. It has the ability to convert all the data items like emails, contacts, calendars, etc. in Offline OST file to Outlook PST file, keeping the original formatting intact after conversion. The tool also supports recovery of data from corrupted OST file.

Conclusion

The blog has been aimed to focus on various issues associated with Exchange Offline OST file and the need for conversion of OST files to Outlook PST files. It further defines a solution through which user can effortlessly convert OST files irrespective of their states to healthy PST file using OST to PST Converter software.

Techniques to Resolve Exchange Error 0x8004010f and Recover PST from OST File

Error 0x8004010f code is one of the most commonly faced errors when Outlook is used in conjunction with MS Exchange server environment. It is a MAPI error and occurs in several situations such as while downloading the Offline Address Book (OAB) files, while synchronizing OAB, while send/receive execution, corruption in OST file, etc. It is also a commonly encountered error when a new account is created on Exchange server. It has been found that if an organization running Exchange owns an offline list of address generator server, the particular error is usually received. This restricts any further synchronization, send/receive operation and it may also result in inaccessibility of OST file. In such situations, it gets necessary to develop any technique to resolve Exchange error 0x8004010f and recover PST emails from OST file.

Occurrence

  • When it is tried to synchronize the offline address list or OST file in Outlook with cache mode in enable state in Exchange, the below mentioned error message occurs in the folder or directory of Sync Issues. The lines of the error are as displayed below:
  • When it is endeavored to synchronize the .ost file or offline address book in Outlook with cache mode in disabled state in Exchange, the error message mentioned below is a common one.
Further, even after receiving error 0x8004010f if it is tried to transmit mails, the error: “Task ‘Microsoft Exchange Server’ reported error (0x8004010F): ‘The operation failed. An object could not be found’” occurs. With this, the synchronization between OST and Exchange server stops, restricting connection to Exchange mailbox and further conversion of OST file into PST format on the local/ client machine.


Recommendation

It generally takes about 24 - 48 hours for Exchange to generate the OAB for newly formed accounts. In the mean time, if any Outlook client tries to download the OAB then the error 0x8004010F pops up which indicates the failure of the download process. Therefore, new users should not attempt to download the Offline Address Book manually in Outlook. However, if the problem exists even after 48 hours manual download should be performed.

Resolutions

1. To fix the error users can view the Properties in Address list, check the settings of the Exchange server System Manager and verify the validity of address book. If the list is not valid then a new list should be added. The other way is to view Properties in Offline Address Book list and check the settings of Exchange System Manager. Thereafter, the validity of OAB in the Offline address list can be confirmed.
2. The error 0x8004010f can also occur while offline address list synchronization, if the client PC with Outlook has proxy settings and Internet Explorer browser is utilized. To eradicate the issue, Internet Protocol (IP) address of Exchange server 2007 Client Access Server should be listed in the exclusion list by utilizing the steps given below.
  • Open Internet Explorer (IE) web browser
  • Click the tab Tools, then click button ‘Internet Options’
  • In Internet Options window click Connections tab
  • In the LAN settings section, click LAN settings button
  • In Proxy Server section of LAN settings window, check ‘Bypass proxy server for local addresses’ box and then click Advanced
  • Then enter FQDN of Exchange 2007 CAS server and click OK
  • Thereafter restart Outlook program
Some more steps should be executed and are mentioned below:
  • On Exchange server, ensure if the offline address list generator server is running or not.
  • On the local PC, configure one proxy for and uncheck the box ‘Bypass proxy server for local addresses’.
  • Try to download OAB manually because the error occurs while downloading the OAB file also. Then check if the error has been fixed or not.
Most probably, the above mentioned techniques to resolve Exchange error 0x8004010f and recover PST emails from OST file are pertinent enough. But it may not be so and in that case an external recovery tool comes as a solution to the problem.

3. If none of the above recommended methods work out, then the cause of the error points to corruption in OST file. In such situations any professional application should be used to recover data items such as emails, calendars, contacts and others from the damaged and inaccessible .ost file. This is because the built-in OST Integration check tool (scanost.exe) that are present in other releases of Exchange has been removed in 2010 edition of Exchange server. Moreover, if executed in other releases it causes data loss. As a suitable alternative, a third party tool called Exchange OST to PST Recovery solution can be adopted without fear. This is because it recovers data corrupted .ost file and exports them in Outlook PST as well as other formats like EML and MSG. It proves as one of the most appropriate techniques to resolve Exchange error 0x8004010f and recover PST emails from OST file type.
