Outlook calendar plug-in with Edge

I have a user on our Enterprise account using Outlook for calendar/mail and Edge as his main browser.  We've set up the Outlook plugin to connect Zoom and it works fine until he shuts down his machine. When he turns back on, the connection to his Zoom account is lost and he needs to log in again through the Outlook plugin.  Does anyone know if this could be an issue with Edge?  Is there a trick for keeping the setting?
