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.
