XCCC: Event 28672 with Error Code 80070057 Occurs During Conferencing Services Startup (309557)



The information in this article applies to:

  • Microsoft Exchange 2000 Conferencing Server

This article was previously published under Q309557

SYMPTOMS

During the Conferencing Services startup procedure, the following event may be logged in the Windows NT Application log:

Event Type: Error
Event Source: MSExchangeCONF
Event Category: (7)
Event ID: 28672
Description: An error occurred while processing the meeting request. Error code: 80070057; Message - The parameter is incorrect.

NOTE: Multiple events may be generated. These events correspond to the number of conferencing resource mailboxes you have configured.

CAUSE

During the Conferencing Services startup procedure, the Conference Management Service logs on to each conferencing resource mailbox so that it can be notified of any conferences that were recently booked. After a conference is successfully booked, the calendar item is moved to the Site Conference Calendar mailbox. However, malformed items may exist in the resource mailbox, for example, a resource that was erroneously invited to a non-Exchange Conferencing Server meeting. These malformed items are considered inappropriate to the Conferencing Services and are flagged as "incorrect."

RESOLUTION

To resolve this issue, remove the calendar items that exist in your conferencing resource mailboxes.

NOTE: These error messages do not hinder or impede the Conferencing Services.

STATUS

This behavior is by design.

MORE INFORMATION

An online meeting request is initially sent to the conferencing resource mailbox, and then moved to the Site Conference Calendar mailbox after the meeting is successfully booked. No calendar items should remain in these resource mailboxes. Any items that continue to exist in these mailboxes are flagged as "incorrect."
