Got an orphaned OST file? Try OST to PST Converter Tool

I have been a regular Outlook user and my company deploys MS Exchange Server for managing our business communication via emails. Over the period of a few initial months I never really understood the technology behind MS Outlook and Exchange Server, as it was not part of my job. I am just a regular guy with a regular, non-technical business profile.

However, that all changed one day when my Outlook OST file became orphaned. Just a day before there had been a lightning strike close at hand which caused a serious hardware failure with our Exchange Server. In order to restore everything, a new server was built. This is where the problem creeped up.

Our administrator created similar usernames as per the previous profiles. Though the sole intention was to keep it as simple as possible so that users don't actually face a problem when they work with the new server, it actually created a serious problem for me.

When I tried to logon to the new server with my old username, my OST file became orphaned as for the Exchange I was a totally different user having a different SID. This threw me in complete panic. I had tons of critical emails, important contacts and all my appointments that I had lost access of.

This brought upon a new revelation about the concept of Outlook OST Recovery and the need of OST to PST Converter tools. An OST file can become orphaned if any of these 3 factors get modified or deleted- MAPI profile on client computer, OST file and user mailbox. In other words, when the user mailbox becomes unavailable on the server permanently, the OST file becomes orphaned.

An orphaned OST file signifies loss of valuable data as it becomes unusable. An OST file can only be accessed with the profile that it was created with. To work around this situation, the OST file needs to be converted into an importable PST file.

An OST to PST Converter tool extracts all the user mailbox items such as emails, contacts, notes, tasks, appointments, journals, To-do lists and calendar entries into a new or existing PST file. More so, the data formatting for emails and messages remains intact after the conversion process.

To carry out OST to PST Conversion, third party tools come handy. There is a huge list of reliable OST to PST Converter tools that can recover data from the orphaned OST file into a usable form for almost all major versions of MS Outlook. After a fair research, I went with “Stellar Phoenix OST to PST Converter”. The software worked wonders for me and I got all my data back within a few simple steps. The demo version of the software showed me all the mailbox items that it could actually recover and once I was satisfied, I went ahead and purchased it. Glad to say, it was worth the money.

MS Exchange Server is widely incorporated in organizations using Microsoft infrastructure. It is a messaging platform that facilitates quick and easy transfer of emails and other information to the users within the organization. Data is stored on the server in the form of user mailboxes and the messages sent by the server are received in the Personal Folders (PST) file on the client side. Another useful file created in MS Outlook is the Offline Folders (OST) file. This file can be assumed as a backup copy of your mailbox on the Exchange Server. It provides offline access to your Exchange data and can be synchronized with the server to reflect changes done to the file in the user mailbox.

In order to access an OST file, you need an Exchange mailbox account. However, you may occasionally run across situations when the OST file becomes unusable. This happens more often due to deletion or removal of user mailbox on the Exchange Server. If the mailbox gets deleted, the corresponding OST file saved locally on the user's computer becomes orphaned. Thus, you might face critical loss of business information. In yet other situations, the OST file may fail to synchronize with the Exchange Server due to corruption in the file or the mailbox on server. OST file corruption may stem from different factors like oversizing of OST (crossing 2GB size limit), malware, hardware issues, application errors, etc. To work around such problems, you should first convert OST to PST, create a new Exchange account, and then import your Personal Folders file with account settings to the new Exchange account. In the event of corruption, the OST file should be repaired and then converted.

Resolving Outlook OST accessibility issues owing to RPC Connectivity

Microsoft Exchange Server creates OST files in the cached mode that are the exact replicas of server mailboxes but are stored on a user's local computer. These OST files need to synchronize with the Exchange Server in order to reflect all the work done in the offline mode on the actual server mailboxes. Sometimes when the OST file is tried to be accessed it returns the following error message:

The name could not be resolved. The Microsoft Exchange address book was unable to logon to the Microsoft Exchange Server computer.

Root of the problem:

The aforestated error is the result of one or more missing/corrupt RPC registry entries. RPCs (Remote Procedure Call) protocol registry keys are deployed by Microsoft Outlook to make calls to the network. RPCs permit users to send calls to many different protocol stacks, the most common one being TCP/IP. If one or more of these registry keys are missing, Outlook fails to establish a connection with the Exchange Server. Moreover, in the absence of required RPC entries Exchange Services are not registered to respond to client requests.


To identify and troubleshoot the RPC issues RPC Dump can be used. The three most essential RPC components required by Outlook to connect successfully are:

1.The endpoint mapper
2.Exchange Information Store service with the Universal Unique Identifier (UUID) of a4f1db00-ca47-1067-b31e-00dd010662da.
3.The Name Service Provider Interface (NSPI) with the UUID of f5cc5a18-4264-101a-8c59-08002b2f8426.

RPC Dump should be run through the following command prompts:

rpcdump.exe /i > rpcdump.txt
rpcdump.exe /p > rpcdump.txt

In order to restore the missing RPC registry values follow these steps:

1.Verify registry entries
2.Verify the version of the DLL file
3.Remove and reinstall TCP/IP

If this is still not able to resolve the issue, then the OST file has become corrupt and needs to be recovered by OST to PST Conversion. Myriad OST errors are encountered owing to corrupt or orphaned Outlook OST files. The only way for efficacious Outlook OST Recovery is through reliable third party tools. One such sought after tool is “Stellar Phoenix OST to PST Converter”.

It is feasible to recover data from a corrupt or damaged Outlook OST file

MS Exchange provides users an option to work offline and access their mailbox data even in the absence of a connection using the ‘Cached Exchange’ mode. These changes are automatically synchronized when a connection is made to the Exchange server. If Outlook synchronization with the Exchange server fails, you may lose all the valuable piece of work that was done offline. As a consequence, you could face serious data loss. This usually happens when your Outlook offline folders (.ost) file is damaged. An OST integrity check tool can be used for repairing the corrupt OST file. However, if the problem persists, you can easily convert your OST to PST using a reliable third-party utility.

For instance, you use MS Outlook 2002. When you try to synchronize your OST file (that has crossed the size limitation of 1.82 GB) with the Exchange Server, you may receive the following error message on your screen:

''Task ‘Microsoft Exchange Server’ reported error (0x00040820): Errors in background synchronization. In most cases, further information is available in a synchronization log in the Deleted items folder. ''

Deleted Items folder of Exchange Server mailbox and OST file do not show the synchronization log.

Why an error is occurring?
Above error message is caused because in Outlook 2002 the size limit of an Outlook OST file is 1.82 GB. As the OST file has crossed the predefined size limit, it may be corrupt.

How an error can be solved?
The following methods will help you resolve this problem:
  • Permanently delete all e-mail messages from any server based e-mail folders that are arranged to be in synchronization with the Outlook OST file.
  • Transfer the data from any synchronized folder to a non-synchronized folder on the Exchange Server.
  • Transfer and permanent deletion of data from a synchronized folder to an Outlook PST file.
However, if you are still facing problems, you need to take help of a third party OST to PST converter. These software are capable of efficiently converting all orphaned or corrupt OST files to equivalent PST files.
