I can't figure this one out... I just put out a few new machines with a brand new Win7 x64 build, including Outlook 2010 x64.
Two of the clients have an issue where they enter someone's name, or someone enters their name, they get the MailTip saying that the address is an invalid recipient address. This happens with the client's OWN e-mail address, as well as a person or two otherwise...
The e-mails will send, and nothing seems to fail about the e-mail, the Mail Tip is just displaying when it shouldn't. Any ideas?
