Thanks Dan and Daley,
Dan, now I understand this icon means, Hi Daley you're right its working now, and there's a lot of function to be enable in conf.php, By the way I was confused why everytime I opened the Webmail services all my previous mails are downloaded again in my MS Outlook, I need to enable my IMAP services coz we need to open our mail remotely even if we're not in our office. I keep playing around some config to edit but no luck, I've been using this feature in sme 5.1.2 and there's no problem. In short everytime we open our webmail in our house, then when we get to office we use MS Outlook and Express and pop our mails it seems is all double even if the mails are already downloaded.
What should be the cause of this, is this a bug of 5.6, is there any update to be download?
Thanks a lot guys, have a nice day...
