How to Resolve Outlook Error 0x00040820 message

Communication is incomplete without exchange of emails and MS Outlook is the best way to send/receive emails. It is easy to use, get hold of and make amendments. It works in accordance with MS Exchange Server that takes care of proper delivery of emails to their respective addresses. Even if there is less or no connectivity, emails are delivered without fail.

Offline Storage Table files take care of emails in offline mode. This folder stores entire email data including mailboxes, attachments etc in an offline folder. This folder allows user to work offline. As soon as MS Outlook finds internet connectivity, the OST folder is synchronized with Exchange server and emails are sent/received. OST files work as backup also when user accidently deletes his email id or under some virus attacks.

There are instances when you might be trying to synchronize the OST file in MS Outlook 2002 with MS exchange Server and it fails giving you the following error:

“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.”

This is one of the problems in OST files, called as oversized OST file issue. When OST files reach their upper size limit that is of 2GB, users are unable to access entire emails and other related data from these offline files. This was a common issue with MS Outlook 2002. One can take some preventive measures to avoid such mishap:

  • Delete all unwanted items from the Server based email folders permanently
  • Move entire data from synchronized folder to a non synchronized folder on the MS Exchange Server
  • Move data from synchronized folder to a PST (personal storage table) file and delete the data from synchronized folder permanently

MS Outlook has an inbuilt tool to deal with such issues. Scanost.exe file can be easily located at:

C:\ Documents and Settings\ username\ Local Settings\ Application Data\ Microsoft\ Outlook\ outlook.ost

Scanost.exe is the utility that helps in removing extra space, which appeared due to the permanent removal of this data. If there is no empty space, Scanost.exe will not work at all. It runs to synchronize and compare missing files and is an integrity check tool.

The best alternative to successfully deal with OST files error is to convert it to PST file format and save it separately. Permanently deleting or shifting emails from the inbox is not so easy and doing it all manually requires high expertise and technical skills.

Usage of third party software, Kernel for OST to PST software is preferred. This user-friendly, easy to use interactive software easily convert OST to PST within few clicks. Follow this to get more detailed information about conversion. The software flawlessly converts entire mailbox items keeping their hierarchy and format intact.
