SYMPTOMS
When the information store (Store.exe) receives a message that includes a double-byte character set (DBCS) display name with a missing tailing byte by means of Post Office Protocol version 3 (POP3) or Internet Message Access Protocol, Version 4rev1 (IMAP4) protocol, the information store causes an access violation with the following call stacks:
