Dear @Bob Seals
Thank you for posting your question in the Microsoft Q&A forum.
Based on your description, that message usually shows up if there’s a problem with your account or the Microsoft servers itself. It could be a temporary issue, so firstly, try restarting Outlook or your computer.
This is something known from Microsoft:

User impact: Users may be unable to access their mailbox using any connection methods. More info: Impacted connection methods include, but may not be limited to: - Outlook.com - Outlook Mobile - Outlook desktop client
Here are some suggestions maybe helpful to you:
- Check Internet and VPN
- Make sure you have a stable connection.
- If you’re on a VPN, disconnect and try again.
- Update Outlook App
- Go to File → Office Account → Update Options → Update Now.
- Outdated builds often cause this error.
- Sign Out and Sign Back In
- Remove the affected account from the app and re-add it. This refreshes authentication tokens.
