I have a user who proxies an account to address the email. On email
that she has open and responded to, the read status will change back
to un-read. This is causing frustration because then she has to go
back and confirm the message has been addressed.

This does not happen on all message, but it does happen several times
a day.

There is no device being synched with the account. GW windows client
version 8.0.2 HP1, backend 8.0.2 HP2.

No other users proxy the account.
