You cannot delete a new MessageBox in BizTalk Server 2004 (835863)

SYMPTOMS

If you create a new MessageBox in the Microsoft BizTalk Server 2004 Administration Console with the Disable new message publication option enabled, and then you try to delete the MessageBox immediately, you receive the following error message:

The MessageBox cannot be deleted because it may still contain incomplete instances. Ensure that there are no incomplete instances in the MessageBox, and try again.

CAUSE

BizTalk Server does not know for sure that there are no active instances of a MessageBox. The error message that is described in the "Symptoms" section of this article is a generic error message to tell users that there may be incomplete instances.

RESOLUTION

Once you create the MessageBox, you must wait until the cache refresh interval passes before you delete the MessageBox. This delay makes sure that there are no active instances.

To determine the cache refresh interval, follow these steps:

Open the BizTalk Server 2004 Administration MMC snap-in.
Right-click Microsoft BizTalk Server 2004, and then click Properties.
Click the General tab.

The value of the cache refresh interval is displayed in seconds.

After you disable the MessageBox publication, wait until two times the specified cache refresh interval has elapsed before you try to delete the MessageBox. For example, if the cache refresh interval is 15 seconds, wait 30 seconds before you try to delete the MessageBox.
