Outlook / Microsoft 365 Sync Troubleshooting
What this is and why it happens
Section titled “What this is and why it happens”Microsoft Entra is a service that helps your company control who can access what in your organization. It allows your IT team or an admin to manage users, their devices, and the apps they use.
Often, companies prevent team members from granting third-party applications access to their company’s data without administrator review and approval, to ensure the app meets security and compliance standards.
