About the impact of user provisioning from Azure AD

Hi.

The Zoom account and the Azure AD account used for authentication in our university's various systems are currently separate. I'm thinking about switching to license user provisioning from Azure AD. However, many of the license users currently registered with Zoom are using the same email address as their sign-in ID as their Azure AD account. If a user specified for provisioning to Zoom from the Azure AD side has the same email address, what would be the impact on the originally registered Zoom user account? For example, would any data recorded and saved in the cloud with that account disappear?
