A corrupted Lotus cc:Mail message (.ccm) file may cause the Microsoft Exchange Connector for Lotus cc:Mail to use up to 90 percent of the CPU and subsequently stop the processing of all inbound mail messages.



CAUSE
The 'Contents:' field is mandatory in a cc:Mail message. If the cc:Mail message is missing this field because of corruption in the body, the cc:Mail Connector loops indefinitely.

WORKAROUND

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 3.
