All good after the posting below
Mark from OpenDNS, support lead responded to my support request and shed some light how this recent snafu I had with my OpenDNS configuration.
Apparently he said, I have selected Webmail as a category to block in my filter setting. Hmm…
Anyway, the initial setting I selected was “high” and I customized it by removing certain categories like social networking, visual search engine etc.
Maybe, just maybe I overlooked the Webmail category….
Anyway, the question I have is, how come Hotmail was not categorized as Webmail?
In addition to resetting the password etc, I have also now added two white list, live.com and google.com - just to be safe.
Will continue to use this OpenDNS and see what other issues I may encounter in my home network in Dubai.
I may register the IP address of the network in Singapore, that is when I get home.
