Inbox "read" messages deleted when quit inbox folder

[Guest]

My Windows Mail is OK, but few days ago something happened with my inbox, all
messages marked as "read" are deleted when I quit inbox and come back. I can
read the messages, they are not deleted as long as I do not quit inbox, but
as soon as I do it, when I come back, messages are gone forever, they are not
even in the "deleted items". Partially I solved the problem by selecting "do
not mark messages as read" but that's not a long term solution. This problem
occurs only in Inbox folder and only with "read" marked messages, all others
remain undeleted. Any ideas? Thanks.

Thank you brink, it works again! I really don't know how it could happen, I
didn't change any setting! Anyway, thanks again.

My window mail is deleting the mail that I reseve but have not yet read, can
you help me find a solution? I've had this problem for a couple of days now.
I just don't understand why.
