'Problem occurred while doing OST sync operation' Error and Recovery

Outlook offline folders or OST files give an efficient medium to work with Exchange Server contents while no network connection is available. When you connect to the network connection, you can synchronize the folder with associated Exchange Server mailbox and update its contents. The OST file in such situations gets converted into a PST file that you can use with Outlook. However, in certain conditions, you might fail to do so. The OST file synchronization operation might fail and the OST file might remain orphaned. To cope up with such problems, you need to use a third-party tool that could Convert OST to a Outlook usable PST file.

For an instance, consider that try to synchronize an OST file, but the sync process fails. When you view the Exchange Server event log, it shows the following entry:

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

The error further describes the message details and name of the folder last synchronized.

Cause

OST Sync process might fail due to below possible reasons:

1-The user has performed some changes in its profile settings that has changed the server name and other items

2-The associated mailbox contains one or more damaged email messages.

3-No local area network access is available to the client computer

Solution

To solve the above discussed issue, try following these steps:

1-You need to ensure that there has been no profile editing at client computer. If it is, correct them.

2-Make sure that the user mailbox is healthy. Delete damaged email items, if any and then duplicate the behavior

3-Try synchronizing the mailbox after some time when proper network connection is available.
