When you send and receive in Outlook, the personal folder
or offline folders that you are delivering mail to may stop accepting new
This problem can occur because of a modification in Outlook
2002 that limits the size of personal folder (.pst) and offline folder (.ost)

corrupted. Mail delivery to the file stops, but you do not receive an error
message that indicates why.

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
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:
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
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.
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.
Both offline files and personal folders files stop accepting data in Outlook 2002 and Outlook 2003
