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.

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.

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.

Resolve:

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.

Professional users are cognizant about the fact that Exchange Servers are not free from faults. By the same token, some users would require to access their mailboxes and data from multiple devices and locations. It is not expedient that accessibility to Exchange Server can be maintained every time, everywhere.

As a resolve, Microsoft offered Exchange users a perk to work on their emails and Outlook items even in the absence of connectivity with the Exchange Server. OST files are Offline Storage Table files that are the clones of an Exchange user mailbox and are stored on the local machine. Whatever changes are made to the user mailbox or emails in the OST file get updated on the Exchange Server mailbox by synchronizing the .ost files with the server.

OST Corruption

Though, it does seem like a piece of cake to work both on-line and off-line on MS Outlook without the shackles of device or location dependency, there is a flip side to the coin as well. The OST files succumb to corruption owing to multifarious reasons like:

• Hardware failure (disk crash)

• Abnormal Outlook termination
• Virus attack or Trojan malfunction
• Errors during synchronization

Resolution

These factors forestall the automatic synchronization of Outlook OST file with the MS Exchange Server.

Tips to Solve Error: '.ost is already in use by the maximum number of applications'

An Outlook Offline Folder (.ost file) allows users to access Exchange mailbox data even in offline mode and then synchronize the changes at next secure connection with Microsoft Exchange Server. This efficiency of Outlook is quite useful in scenarios of low or inappropriate connectivity. But similar to other files, an OST file can also get corrupt. Such situations necessitate that you either restore from backup or use a Convert OST tool that retains the capability of converting a corrupt OST to PST file and thus recover ost file.

Following is an instance of such probable events in Microsoft Outlook. Consider a user using Microsoft Outlook 2003. At one point of time, it might come across the below error message:

“The file OST_File_Path\outlook.ost is already in use by the maximum number of applications. Close some of the applications, and then try again.”

Outlook user receives this error repeatedly.
