With further testing, I am NOT buying this line of thought that it is the "blame all" Antivirus app that is causing this problem of getting duplicate emails (downloaded at the same time) with MS "Live Mail"!! And here is my proof -
My wife and I each have brand new notebooks, here's an HP and mine an MSI, both came preloaded with Windows 7, Live Mail and in neither case did we activate or use the 90 day Norton AV. In both cases, I uninstalled Norton immediately and installed on both
AVG Free (same version), just as I do for many of my clients (I am an IT hardware consultant).
She has three of four email accounts she uses regularly and as I do. With AVG Free, all scanning modules active on both notebooks, her notebook does NOT download duplicate emails. On mine it does.
I've turn email scanning on and off and on and off and it makes no difference, Live Mail downloads duplicates most of the time.
As far as I am concerned this is a bug in Live Mail, since I've noticed also that mine is slow to delete, mark as SPAM, move, etc. emails and on her system, this is not the case (my MSI has a 2.6ghz Core2Duo, her's a 1.8ghz AMD Dual Core, so it is not a
processing issue).
So, perhaps uninstalling Live Mail and reinstalling is a solution? Can this be done with Win 7??
Of course I'd just rather have just plain Windows Mail; or better yet Outlook or even Outlook Express!!! NEVER any problems like this with either of those email clients!
