Dear Beena Ojeda,
Good day! Thank you for posting to Microsoft Community.
I'm sorry to hear that you're experiencing issues with Outlook. It sounds like you're being prompted to allow the server autodiscover-s-outlook.com to configure your account settings, but nothing happens when you click "Allow".
Typically, this warning appears when Microsoft Outlook redirects an AutoDiscover operation from HTTP to HTTPS. Therefore, when you click allow in your outlook, that means you will not be asked or get this warning pop-up message about this specific server again for this Outlook for Mac profile.
However, in order to understand your query and provide possible solution, could you please provide us with the screenshot of your Outlook version details? see What version of Outlook do I have? - Microsoft Support.

I look forward to your response. Kindly note that the above requested information is required for further analysis and troubleshooting of your situation. Your patience and cooperation are much appreciated.
Thanks for your precious time. Have a nice day.
Sincerely,
Libeamlak | Microsoft Community Moderator
