Sending, receiving, and organizing email in Outlook.com
Hi, I'm John! I will help you with this.
You're not alone, many users are currently experiencing the same issue with Outlook. It appears to be a widespread connectivity problem.
You can check the official service status here: https://portal.office.com/servicestatus/ expand “Microsoft consumer products”and look for the Outlook.com section for details.
For now, please wait until Microsoft resolves the issue and try again later.
I really hope this information is helpful!
