Outlook 2019 stopped working

I am a licensed user of Office 2019. My Outlook stopped working one day, and displays these error messages:

Outlook cannot log on. Verify you are connected to the network and are using the proper server and mailbox name. The Microsoft Exchange information service in your profile is missing required information. Modify your profile to ensure that you are using the correct Microsoft Exchange information service.

Second message (after I close the first message)

Cannot start Microsoft Outlook. Cannot open the Outlook window. The set of folders cannot be opened. The information store could not be opened.

It was working one day and broken the next day. I did not change anything and I have the correct passwords for all my Microsoft email accounts (I can access those accounts in the browser and on my cell phone).

What is happening, and how can I fix this?

Using Windows 10, latest patches.

If Outlook 2019 is working well but you cannot log in, you need to re-create your Outlook Profile.

Make sure you have a backup of your email, then go to Control Panel, Mail and remove the Outlook Profile (removes your account).

Restart, make a new Outlook Profile and then try Outlook again. It should work at that point.
