SYMPTOMS
========
When a news client logs on to an Exchange Server computer that acts as a news
server, and then issues a "STAT" command, the Exchange Server information store
service may stop unexpectedly because an access violation occurs. The stack dump
is similar to the following:
FramePtr RetAddr Param1 Param2 Param3 Function Name
1143f984 78021646 1143f99c 011315b7 1143fdf0 0x7801031c

CAUSE
=====
The issue can occur if the information store sends a message in response to the
client that issued the STAT command. Because the related message has a percent
sign in the message ID, the information store incorrectly processes the
character as a type field character when the response message is composed, which
results in an access violation.
RESOLUTION
==========
To resolve this problem, obtain the latest service pack for Exchange Server 5.5.
