# Microsoft 365 Connector

The shared connection that the Microsoft 365 modules use.

The shared connector holds one Microsoft tenant connection and links HR users to existing Microsoft accounts. It is the dependency for Account Management, Outlook Email and Outlook Calendar Sync; enable only the optional modules you use.

An administrator with **Manage settings** configures tenant ID, application ID and client secret in **Settings → Microsoft 365 connection**. The saved secret is encrypted and never displayed. Leave the secret blank to preserve it, or explicitly clear it. Save before running **Test connection**. The test verifies credentials; it does not prove every module permission or mailbox is ready.

To use an existing account, an administrator with **Manage settings** and **Edit employees** opens the employee profile's **Microsoft account** tab and links its Microsoft sign-in name. Unlinking removes the local association and stops features using it; it does not delete or disable the Microsoft account.

Changing the tenant requires linking accounts for the new tenant. Old links and sync checkpoints are not reused across tenants.
