Ever since I installed Avast 5.0, I am getting the following error in Outlook Express when sending emails using Hotmail:
“Protocol: SMTP, Server response: '503.5.5.2 Only one STARTTLS command can be issued per session, Port: 587, Secure (SSL): Yes, Server error: 503, Error number:0x800CCC65”.
Working environment:
Windows XP Professional with SP3
Outlook Express 6
Avast 5.0.545.
I forgot to mention that the error comes when sending emails using hotmail (have modified original post to reflect this). Microsoft specifies port 587 for SMTP when using Hotmail in OE.
