I have been using Outlook 2007 for many years (Outlook 2003 before that) and have never had any problems. I have updated to Win8 on my desktop about a month ago and the day before yesterday I found that I was unable to send any mail but my receive was OK. This also happened at the same time on my laptop which is running Outlook 2007 on Win 7. Both machines are 64 bit. Upon sending on both I get the error -
'Task 'my email address here' - Sending reported error (0x800CCC78): 'Cannot send the message. Verify the email address in your account properties. The server responded: 550 Not permitted'
Needless to say I have checked everything and tried to send to different addresses.
I saw mention somewhere that Win 8 does not support POP - my three accounts are POP/SMTP, but if this is a problem why am I seeing it on my WIN 7 laptop?. I have my own domain name and my one account the add is
pop.oneandone.co.uk (my domain supplier)
I also use a spam filtering service (clearmymail) - all my incoming mail goes through them and I get regular reports and all of that is OK.
I am not keen to go over to Outlook.com as I will loose my email address.
All help gratefully received
