When a Virus is detected within the attachment store, it is important to know which mailbox this message belongs to so that the infected workstation can be identified and cleaned.
Run the following query against the Archive Manager Database:
select name from mailbox
where mailboxid in
(select mailboxid from mailboxmessage
where messageid in
(select MessageID from attachment where attachmentfileid='45'))
Replace the number 45 with the name (Number) of the infected file.
