Outlook is specially designed for business users. In general, Outlook is used to send and receive e-mails. You can also maintain information regarding organization and people with whom you’re in contact and also you can keep a calendar of your events, appointments and meetings etc. Outlook is tightly incorporated with the Internet Explorer so that you can access the internet newsgroups and sites. Basically, Outlook has three different options for storing Outlook files i.e. Exchange server mailbox, PST file and OST file. PST (Personal Storage File) files are able to store all emails, contacts, calendar entries, tasks, notes etc.

You can encrypt your PST file using passwords for greater security. Whenever Outlook synchronizes with Exchange Server entire offline data gets reflected in Outlook. Hence, the sending-receiving process is continuous and users can perform their work without any delay. However, there can be synchronization difficulties at times. This leads to the inaccessibility of OST files and the entire offline work done gets trapped. The situation can be overcome with the help of an effective OST to PST conversion tool.

Actually, PST files do not have a built-in capacity for synchronizing the mailbox with Exchange Server mailbox. If you have configured the Exchange server mailbox as the default store location then you can work offline using OST (Offline Storage Table). It works both in a normal offline mode and also cached exchange mode, which automatically synchronizes data between the local cache and the server even when the server connection is not available. The most common synchronization error which you can witness is:

            “A problem occurred while doing OST sync operation for user 'username'”

This error further describes the message details and the name of the last synchronized folder. This failed synchronization error can occur if you have performed some changes in your profile settings or has changed the server name and items. There could be a problem in linking with a mailbox containing one or more damaged email message. No local area network access is available to the client computer.

Another nasty error which you witness is:

“Problem occurred while doing OST sync operation”

To overcome this, first, make sure that there has been no profile editing on a client computer. If a change has been made, then make sure the mailbox is healthy. The damaged email items should be deleted and you should synchronize the mailbox after some time when the proper network connection to Exchange is available.

To avoid above mentioned scenarios remove all the unwanted items from your Exchange server based email folder which is set to be synchronized to the OST file. Always move your files from a synchronized folder to any non-synchronized folder on Microsoft Exchange Server and move your significant files from synchronized folder to PST file and then permanently remove data from a synchronized folder. If the OST file is damaged and cannot be converted into PST, use third-party applications to Convert OST to PST File.
