outlook express 5 - messages received, but no messages in in box

using OUTLOOK EXPRESS 5.

sometimes, outlook express beeps after checking for messages, states 1 or x messages received at the bottom...

and when i go to in box, there are NO new messages.

any ideas?

i've updated and run norton antivirus and no viruses found...

HELP!

 

hello, Do you have any mail(s) blocked ? They would come in to the trash can intead

 

yes, this may be the problem. i found an e mail in the delected mailbox. i will watch and see if this happens each time i appear to be missing one or more e mails..

thank you

 

you can go to oe click tools - message rules and look at the blocked list
