All messages showing as new

[D Canfield]

I just migrated about 3000 accounts to cyrus, and most have gone without 
a hitch.  However, I have one single account in which all of the 
messages in the account show as new/unread no matter how many times a 
message is viewed and no matter what client we use.  The account has 
full lrswipcda acl access to it's own mailbox, and new messages are 
delivered without a problem.  I've run reconstruct -f a number of times 
as well, and the issue persists.  Can anyone offer any suggestions?

Many thanks in advance.
