Hi, I'm Estrella. I'll do my best to help you.
There are currently several reports of the same issue with Outlook. From what I’ve checked, it appears to be a problem with the service. You can check the status here: https://portal.office.com/servicestatus/
You will need to wait until Microsoft fixes the issue.
Thank you so much for the prompt response! I will bookmark the link and track the resolution there.
