+ 0 Votes Problem with Outlook 2010 Tony AW 2 years ago It has now tranpired that the problem lie with the router. Whilst this appeared to be working OK it was not allowing messages sent auth.smtp. The router has been changed and everthing now seems to be fine. Incidentally the router was my third smc router; none have lasted for more than two years. This one was a year old and still undrer warrenty, but to claim this is from where I am in Thailand is not worth the effort which would be involved; and I cannot afford any downtime.Thank you.
