Hi Gina,
This issue is likely tied to an ongoing service incident in the Microsoft 365 admin center MO1550821. Microsoft is currently investigating a widespread service degradation preventing users from connecting to multiple Microsoft 365 services, including Exchange Online.
Currently, Microsoft is actively investigating the issue on their end, so there is no action needed from end users at this time.
In the meantime, please ask your IT administrator (if they still have access to the Microsoft 365 admin center) to monitor MO1550821 under Health > Service health for further updates. Having them use the "Report a problem" feature will also help Microsoft log the impact on your organization's tenant.
I hope this information is helpful.
