OL98: "Error in Background Synchronization" Message Is Slow to Display (241962)
The information in this article applies to:
This article was previously published under Q241962 NOTE: The procedures in this article only apply if you have installed Outlook with the Corporate or Workgroup option. With this option, you can use Messaging Application Programming Interface (MAPI) services. To determine your installation type, click About Microsoft Outlook on the Help menu. If you have the Corporate or Workgroup installation, you see "Corporate or Workgroup".
SYMPTOMS
If a dial-up connection disconnects while you are synchronizing folders, it may take up to 30 minutes for the following error message to appear:
Error in Background synchronization. See detailed log in Deleted Items folder.
CAUSE
This may happen on a mobile computer that has a modem and a network interface card (NIC) installed. While it is connected to the Local Area network (LAN), it may get its Domain Name Server (DNS) and Windows Internet Name Service (WINS) addresses via the Dynamic Host Control Processor(DHCP). The NIC will attempt to connect to the DNS and WINS servers until they time out, even if it is not connected to the network.
Another reason for the delay is that every entry listed under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Exchange\Exchange Provider\Rpc_Binding_Order
is tried. This adds up to a timeout of 2-3 minutes per folder. These networking settings are responsible for the long timeout values.
RESOLUTION
Making the following configuration changes may help reduce the timeout per folder to less than a second. - Remove unnecessary DNS entires. The computer will try to connect to any DNS address bound to your network adapter until it times out. For additional information on how to resolve this problem, click the article number below
