I have Windows Live Mail.  My sister has Outlook.  We email every day, sometimes several times per day.  Occasionally, an email sent from one of us never arrived at the other's inbox.  Not in trash, not in junk, not in spam, not blocked, as we email daily.  99% of them get through but occasionally they don't and when we try to forward from the sent column, those don't arrive either.  We thought it was because of fonts that the sender sent in and receiver didn't have but it is not that; we have retried and the font just gets changed to default font.  We both used to have Outlook Express and it used to happen back then, also, so I don't think it matters which kind of mail program you are using.  Does anyone know why some emails just never arrive and what happens to them and why? 

This is not a huge problem because after we realize it has happened, we just copy from the original sent email into a new email.  Sometimes it comes through right away and sometimes it has to be sent several times.  We are just really curious as to why this happens; would appreciate if anyone can shed some light on the subject.  Thank you.

Also does anyone know how to get an email or even snail mail to Microsoft?  I haven't been able to find any way to contact them.  I want to tell them how much a lot of us miss stationery that Outlook Express used to have.  I don't understand why WLM doesn't have any, as it was supposed to be an improvement on Outlook Express, but in that respect, it fails.  The only program I can find with stationery is Incredimail and my provider doesn't recommend it and won't support it.  They think it will cause security problems. Also, if you get Incredimail, all your email comes in there, you can't maintain other email accounts like WLM or Outlook or Gmail.  I need two because sometimes one account has problems with it.  Thanks again if anyone can help.
