Problem Syncing Outlook Hotmail Account to IQTELL Website

I've tried to sync my Outlook Hotmail account with IQTELL.com, but with no success. When I'm at the IQTELL website I select Setup a new email account. I'm then prompted to select a provider. I select Outlook. I'm then prompted to enter my email address and password. I enter the email address and password that I use to access my Outlook Hotmail Account on a daily basis and then click add. I then receive the following error message: "Could not establish connection to the mail server with the specified credentials. Please verify the account settings and that you selected the correct provider." I've asked the IQTELL staff to help me breach this impasse, but nothing they've suggested has worked. What's odd is that I'm able to add my Gmail Account to the IQTELL website with no problem. I just enter my email address and password and presto I'm there. I'm hoping that someone in this community has the answer that will help me setup my Outllook Hotmail email account on the IQTELL website. I'd like to be able to access both my Gmail and Hotmail accounts from the IQTELL website.

Thanks in advance for your help. Sincerely, Bryan
