A serious and urgent issue: my emails have suddenly stopped showing attachments, even for older emails. The emails show the larger size but the "Attachments" page empty. I found _compmail.pegasus-mail.ms-windows.narkive.com/blRdiWXT/attachments-not-showing-up but that was 18 years ago. I don't have a state.pmj**; it may have been accidentally deleted. What should I do to safely fix the problem?
