I have a PC running Windows 7 with Office 2010 SP1. I connected a POP3 account to it and imported contacts into it from Windows Mail as contact cards.
However replying to some emails doesn't work. Probably about 1 in 5 of them. I can't seem to find anything unique about the email addresses it wont reply to.
As an example Karen (Karen@email.com) has sent an email when I click reply it passes Karen into the reply to field however it doesn't validate as an email address so when you try to click Send it it doesn't recognise 'Karen' as a valid email address. Yet other email addresses work absolutely fine when I reply to them.
If I add Karen as a contact (Karen a s a display name) and her correct email address it will work as the Check Names function finds the correct info for 'Karen'
Any ideas what could be causing this. This is happening on at least 10+ unique email addresses from different domains so it's not a problem with the email address I'm sending to.
Seems to be something within Outlook causing this.
Thanks for any help in advance.
