What Exchange administrators realize is that any sort of malfunction or Exchange Server failure can result in downtime that can prove to be disastrous for the organization.

For a business enterprise it can be critical and lead to a great loss.

This makes it possible for the Exchange administrators to bring down the server for maintenance or any other purpose without disabling all the access to the user's mailbox data. Once the Exchange Server is back online, the OST files synchronize with it and whatever work has been done offline gets updated onto the server mailboxes.

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.

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.
