When you send and receive in Outlook, the personal folder or offline folders that you are delivering mail to may stop accepting new items.


This problem can occur because of a modification in Outlook 2002 that limits the size of personal folder (.pst) and offline folder (.ost) files to less than 2 gigabytes (GBs) to prevent the files from becoming corrupted. Mail delivery to the file stops, but you do not receive an error message that indicates why.


To resolve this problem, obtain the latest service pack for Microsoft Office XP. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

The English version of this fix should have the following file attributes or later:
   File name        Version   
   Exsec32.dll     10.0.3117.0
   Outllib.dll     10.0.3124.0
   Outlph.dll      10.0.3124.0
   Rm.dll          10.0.3012.0


Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Microsoft Office XP Service Pack 1.


After you apply this fix, when you attempt delivery to a .pst file that is full (approximately 1.82 GB, 1,957,052,416 bytes, or 1,911,184 kilobytes [KB]), Outlook 2002 displays the following error message in the Outlook Send/Receive Progress dialog box:
Task 'Microsoft Exchange Server - Receiving' reported error (0x8004060C): 'Unknown Error 0x8004060C'
0x8004060C is a unique error code that is designated for a failure to deliver to a .pst file Inbox because the .pst file is full. If you attempt to save any other items to the .pst file, such as an Appointment, Task, or Contact, you receive the following error message:
The file file_name has reached its maximum size. To reduce the amount of data in this file, select some items that you no longer need, then permanently (shift + del) delete them.
When you attempt delivery to an .ost file that is full, you receive the following error message in the Outlook Send/Receive Progress dialog box:
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.'
If you check the Deleted Items folder, there is no synchronization log resulting from this error.

Outlook 2002 users who are connected to an Exchange Server or Exchange 2000 Server computer who have mail delivery set to a .pst file do not receive any notification when the .pst file becomes full. Mail simply stops being delivered to the .pst file and accumulates on the server.
