I know many of you are frustrated with this but please do not blame Aqua Mail. This is a Microsoft Outlook problem and they are still unclear on how to fix it. You should be following these complaints with Microsoft. Not only does my Hotmail account not work with aqua mail but it also doesn't work with Fairemail. Microsoft outlooks own Twitter DMed with me and then they want me to follow a support complaint with Outlook support. Who is managing their Twitter page if not outlook support? I go to their Outlook support page which is useless. Can you log in to your Microsoft account, yes. Can you log in at outlook.com, yes and then they act like there is no problem. There are more ways to access your account than that. Then if you try digging further into their support pages they just reference using their app as if that's the only app they can use. All my other Outlook accounts work just fine except for my Hotmail so something strange is going on.
