I have an office 365 for home subscription and downloaded outlook for mac. It was fine for the first several weeks. However, recently, when I open Outlook, I always get the prompt that - "Outlook couldn’t verify your Office 365 subscription. Please make sure that you’re connected to the Internet." There are 2 buttons, "Remind me later" & "Retry". Clicking latter only pops up the prompt again so I just click on the former to dismiss the prompt. Everything works fine after that. I enter my password and get connected. Note that I don't want save my password in keychain for security purposes - not sure if that has something to do with this prompt. I've read that it has something to do with proxy and my internet. I only use my home internet as my mac is not my main work laptop.
