Resolving the 0×00040820 error
The concept of synchronizing OST file with the Exchange Server comes into picture when after working in the offline mode, you want that the changes made in the offline mode must be reflected on to the Exchange Server mailbox.
However, you are not always successful in synchronizing OST files with the Exchange Server mailbox. Many a times, you fail to synchronize your OST file with the Exchange Server mailbox and get an error message instead.
Let’s consider a real life scenario wherein when you attempt to synchronize your OST file with Microsoft Exchange Server mailbox, you get an error message. Here we would like to mention that your OST file has reached the 1.82 GB size limit. The error message is as follows:
“Task ‘Microsoft Exchange Server’ reported error (0×00040820): Errors in background synchronization. In most cases, further information is available in a synchronization log in the Deleted items folder.”
The aforementioned error message suggests you to look for further information in the synchronization log present in the Deleted Items folder, but the fact is that the synchronization log is absent in the Deleted Items folder in the Exchange Server mailbox. It is also not present in the Deleted Items folder in the OST file as well.
Now let’s focus on knowing the actual cause behind the occurrence of the aforementioned error message.
The reason behind the error is that your OST file has reached the 1.82 GB size limit and this is the size limit set for OST file in Outlook 2002. This simply means that whenever your OST file in Outlook 2002, reaches the size limit of 1.82 GB, there is a possibility that it becomes faulty.
In order to resolve the aforementioned error message, take up any of the following measures:
Use the Shift + Delete key combination to permanently delete unwanted and undesirable emails and other data items from the Exchange Server mailbox.
On the MS Exchange Server, move the data from any synchronized folder to non-synchronized folder.
Move the data from the synchronized folder to PST file.
However, if you are not able to resolve the issue even by any of the aforementioned measures, then use a professional OST to PST converter tool to convert OST to PST files.
