FAQ — Microsoft 365

Do I need Professional?

Yes — feature microsoft365 typically from Professional.

One Azure app for all my tenants?

LIRENO stores setup per tenant number. Reusing the same Entra app is your choice — values must be saved per MND.

Why is the secret empty after save?

By design — encrypted storage. Leave empty to keep; enter a new value only to replace.

Authenticator worked, then error?

Usually redirect URI / wrong app. → AADSTS500113 · M365 troubleshooting
