SYMPTOMS

In large systems, public folder replication status messages may grow to a large number and size.

CAUSE

This issue can occur because in Exchange Server 5.5, each server in the Exchange Server organization that has a public information store sends at least one status message each day to every other server in the organization that has a public information store. In an Exchange Server organization that has hundreds of servers that have public information stores, these public folder status messages can overload the low bandwidth links.

RESOLUTION

To resolve this problem, obtain the latest service pack for Exchange Server 5.5. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

STATUS

Microsoft has confirmed that this is a problem in Microsoft Exchange Server version 5.5. This problem was first corrected in Exchange Server 5.5 Service Pack 4.

MORE INFORMATION

A new algorithm is implemented in this fix that dramatically reduces the number of public folder status messages in most systems.

The following are the changes that the new algorithm provides:
  • The unconditional status broadcast and site-folder broadcasts during the information store startup are now removed.
  • When the status of a public folder is broadcast once, another status broadcast is not sent unless some changes are made locally to that public folder.
  • Each time a change is made, the status send time is set to 24 hours from the time that the change was made. The network is not flooded with the same status message over and over. Instead, the message is sent more than once only if something has changed.
