I installed IE7 last weekend and have given it a run through and all seems well. However after a few days I learned that some of my sent emails (outlook express) were not arriving. It now seems that particular email addresses are OK and receive my mail as normal while others do not. I cannot see any pattern to this but it is totally unacceptable. As the problem seems to have started about the time of IE7 I am assuming this to be the problem. I have found that system restore will not let me go back to any point before the ie7 install. I am contemplating 'rolling back' to IE6 which seems fairly easy if I am to believe some of the posts I have read - using add/remove software from control panel and rebooting twice. Has anybody else had this sort of problem with their mail ? Thanks.
