need assistance with sql query

in my web application, I have a feature where users can message one another. In their "inbox", I currently have a list of all of their message records displayed in the following format:

FROM            SUBJECT                                             DATE
User A           re: subject for msg1                       10-9-2015
User B           re: subject for msg1                       10-8-2015
User A           re: subject for msg1                       10-7-2015
User B           re: subject for msg1                       10-6-2015
User A           re: subject for msg2                       10-9-2015
User C           re: subject for msg2                       10-7-2015
User A           re: subject for msg2                       10-4-2015
User C           re: subject for msg2                       10-1-2015


Instead of having each message displayed in my table, I want to just have one version of each message, similar to how gMail displays messages. so it would look like:

User B           re: subject for msg1                       10-9-2015
User A           re: subject for msg2                       10-9-2015

the latest version would be what displays. For my table structure, I have a table named tblMessages that contains a messageID column, which is unique to that message, as well as a conversationID column, which is how I group messages between two users together. Right now the following query gives me ALL messages for one user:

select id = messageID, 
         starred = case starred when 1 then 'starred' else 'not starred' end, 
         [from] = displayName, 
         subject = msgSubject,
         [date] = sentDate, 
         beenRead = case beenRead when 1 then '1' else '0' end 
from tblMessages m 
         inner join tblUsers u on m.msgFrom = u.userID and u.status = 1 
where msgTo = 100 and 
        to_deleteDate is null 
order by sentDate DESC

Select allOpen in new window

how can I tweak it to return the latest message for each conversation?
