Outlook 2007 and Win 7
No previous problems with Outlook and XP. New clean Win 7 installation and now random failures to send emails.
Tried repairs to Office/ Outlook; Uninstalling Norton; fresh set up for each of my email accounts but nothing cures it. Same addresses are rejected with message from System Administrator that "has not been delivered to following Recipients:" - but no details. Failed emails show up in "Sent" folder but account of sender has been changed from david to sue or sue to rod. Test messages between these go through ok. Is this a win 7 problem because I have tried everything associated with other programmes that I or my friends can think of?
