I have almost the same problem with my email. I have noticed it for quite some time and since it is an intermittent problem, I have never done anything about it, but tonight I was frustrated to the point of researching for help!
My problem is that whenever I add a new address in my address book, and then try to send an email, the addresses I just added won't show up in the "To" section. When I go to check the address book, they are there. If I wait a few hours or days, the new addresses will then show up! I also always have an "error" message at the bottom of the pop up window whenever I try to send new emails or forwards. Sometimes the email will send, sometimes it won't.
Also, I set up groups for my address program and it used to work - but now I can't add any new addresses to any of those groups.
All of this makes it very frustrating when you need to send business emails. Please help.
