Calendar service disconnected after M365 migration

My company recently migrated all sister companies under one enterprise Microsoft 365 account. Since then, in the desktop client, I receive the following message: "Your calendar service has been disconnected from your account. Configure Your Settings."

When I click on Configure Your Settings, I am taken to the Zoom website with the "Select a Service" pop-up. I choose Office 365 and click Next, then Authorize. Then I get the following message: "Configure calendar successfully. You can go to client to check your upcoming meetings."

However, nothing changes. I still see the error in the client.

Thanks for any help you can provide!
