Configurare un'applicazione Azure per Teams

1. In qualità di amministratore, accedi al portale di Azure.
2. Fai clic su Cloud ShellPowershell.
3. Se richiesto, crea un account di archiviazione e accetta le impostazioni predefinite.
4. Per creare l'applicazione, inserisci questo comando e poi fai clic su Invio:

   Install-Module Microsoft.Graph -Scope CurrentUser

5. Se viene visualizzato un messaggio che ti chiede di installare da un repository non attendibile, inserisci Y e poi fai clic su Invio.
6. Copia il seguente blocco di codice, incollalo in PowerShell e fai clic su Invio.

7. Prendi nota delle seguenti credenziali e archiviale in modo sicuro. Se le credenziali vengono divulgate, gli hacker potrebbero accedere a tutti i tuoi dati di Teams.
   • Client secret
   • ID applicazione (client)
   • ID directory (tenant)

1. In Windows, crea un nuovo file di testo normale e chiamalo migration_app_creator.ps1.
2. Copia il seguente blocco di codice, incollalo nel nuovo file e fai clic su Esegui con PowerShell.

Per motivi di sicurezza, ti consigliamo di registrare la nuova applicazione come single-tenant.

1. In qualità di amministratore, accedi al portale di Azure.
2. In Azure Active Directory (Azure AD), vai a Registrazioni app.
3. Fai clic su Nuova registrazione e inserisci un nome per l'applicazione (ad esempio, App di importazione avanzata).
4. Per Tipi di account supportati, fai clic su Solo account in questa directory dell'organizzazione per creare un'applicazione single-tenant.
5. Fai clic su Register (Registrati).

Scegli una delle seguenti opzioni:

Opzione 1: aggiungi manualmente le autorizzazioni

1. A lato, in Gestione, fai clic su Autorizzazioni API.
2. Fai clic su Aggiungi un'autorizzazioneAPI MicrosoftMicrosoft Graph.
3. Per le autorizzazioni dell'applicazione, seleziona:
   • Application.Read.All
   • ChannelMember.Read.All
   • ChannelMessage.Read.All
   • ChannelSettings.Read.All
   • Group.Read.All
   • Member.Read.Hidden
   • Organization.Read.All
   • Team.ReadBasic.All
   • TeamMember.Read.All
   • User.Read.All
4. Fai clic su Concedi il consenso amministratore per la tua organizzazione.

Opzione 2: modifica il manifest dell'applicazione

1. Apri il manifest dell'applicazione.
2. Vai a "resourceAccess" : [ ] e scegli un'opzione:
   • Se "resourceAccess" : [ ] ha già un valore, aggiungi una virgola e poi incolla il seguente blocco di codice.
   • Se "resourceAccess" : [ ] non ha un valore, copia e incolla il seguente blocco di codice.

   { "id": "658aa5d8-239f-45c4-aa12-864f4fc7e490", "type": "Role" },

   { "id": "498476ce-e0fe-48b0-b801-37ba7e2685c6", "type": "Role" },

   { "id": "3b55498e-47ec-484f-8136-9013221c06a9", "type": "Role" },

   { "id": "7b2449af-6ccd-4f4d-9f78-e550c193f0d1", "type": "Role" },

   { "id": "9a5d68dd-52b0-4cc2-bd40-abcf44ac3a30", "type": "Role" }

3. Fai clic su Concedi il consenso amministratore per la tua organizzazione.

1. Nel riquadro laterale, in Gestione, fai clic su Certificati e secretNuovo client secret.
2. Inserisci una descrizione, seleziona un periodo di scadenza e fai clic su Aggiungi.
3. Copia il valore del client secret e memorizzalo in modo sicuro. Il valore viene visualizzato una sola volta.

Importante: memorizza le credenziali dell'applicazione in modo sicuro. Se le credenziali vengono divulgate, gli hacker potrebbero accedere a tutti i tuoi dati di Teams.

Fai clic su Panoramica e annota in modo sicuro le seguenti credenziali:

• ID applicazione (client)
• ID directory (tenant)
