I just started getting an error today when I try to send or reply to an email using Outlook 2003 from either my primary email account that goes through my ISP or my Hotmail email account (using the outlook hotmail connector). I tried rebooting, no change. I also tried "Help, Detect and Repair using the Restore my shortcuts while repairing option selected. Over the weekend I installed a VPN from Private Internet Access and I have tried sending emails with it enabled and disabled and the send still fails with this error:
Task 'pop-server.nycap.rr.com - Sending' reported error (0x800CCC78) : 'Unable to send the message. Please verify the e-mail address in your account properties. The server responded: 530 Authentication is required before sending [R0107005]'
I logged on to my ISP's webmail site and was able to send an email to both of my email accounts in Outlook. I have been running Outlook 2003 on this PC since July and this is the first error I haven't been able to resolve. Any help is appreciated. I am running Windows 7 Professional 64 as an O/S.
