I have found that in Outlook Express when I view an unread message on an IMAP
account, it will show up as unread again on the next send/receive (giving me
the "new mail" indication again as well). In other words, the 'unread' flag
is not being changed on the IMAP server. However, I have found that
switching to a mailbox on any other account (such as a local folder) after
reading the message causes the unread flags to be set properly so I do not
get false "new mail" alerts.

My question is, is there any way to either:
1. Set OE to automatically change the flags immediately, or at regular
intervals; or
2. Set OE to automatically switch to the local inbox after a specified
interval, which will force the flags to be updated.

The reason this is a problem is that I often forget to change the mailbox,
so 5 minutes after reading an email I get the "new mail" alert again (and I
am always disappointed!)
