3. Zapisz te dane logowania i przechowuj je w bezpiecznym miejscu. Jeśli dane logowania wyciekną, hakerzy mogą uzyskać dostęp do wszystkich danych Exchange Online.
   • Tajny klucz klienta
   • Identyfikator aplikacji (klienta)
   • Identyfikator katalogu (najemcy)

Ze względów bezpieczeństwa zalecamy zarejestrowanie nowej aplikacji jako jednego najemcy.

1. Zaloguj się w portalu Azure jako administrator.
2. W Azure Services (Usługi Azure) otwórz App registrations (Rejestracje aplikacji).
3. Kliknij Nowa rejestracja i wpisz nazwę aplikacji (np. Aplikacja do importu zaawansowanego).
4. W sekcji Supported account types (Obsługiwane typy kont) kliknij Accounts in this organizational directory only (Tylko konta w tym katalogu organizacyjnym), aby utworzyć aplikację z jednym najemcą.
5. Kliknij Zarejestruj.

Wybierz jedną z tych opcji:

Opcja 1. Ręczne dodawanie uprawnień

1. Z boku w sekcji Zarządzaj kliknij Uprawnienia interfejsu API.
2. Kliknij Add a permission (Dodaj uprawnienie)  Microsoft APIs (Interfejsy API Microsoft)  Microsoft Graph.
3. W sekcji uprawnienia aplikacji wybierz:
   • Calendars.Read
   • Contacts.Read
   • Directory.Read.All
   • Group-Conversation.Read.All
   • Mail.Read
   • MailboxFolder.Read.All
   • MailboxItem.Export.All
   • MailboxItem.Read.All
   • Tasks.Read.All
   • User.Read.All
4. Kliknij Grant admin consent for (Przyznaj zgodę administratora dla) Twojej organizacji.

Opcja 2. Edytowanie pliku manifestu aplikacji

1. Otwórz manifest aplikacji.
2. Otwórz “resourceAccess” : [ ] i wybierz opcję:
   • Jeśli “resourceAccess” : [ ] ma już wartość, dodaj przecinek, a potem wklej poniższy blok kodu.
   • Jeśli “resourceAccess” : [ ] nie ma wartości, skopiuj i wklej ten blok kodu:

   { "id": "798ee544-9d2d-430c-a058-570e29e34338", "type": "Role" },

   { "id": "089fe4d0-434a-44c5-8827-41ba8a0b17f5", "type": "Role" },

   { "id": "7ab1d382-f21e-4acd-a863-ba3e13f7da61", "type": "Role" },

   { "id": "4f0a8235-6f6f-4ec7-9500-34b452a4a0c3", "type": "Role" },

   { "id": "df021288-bdef-4463-88db-98f22de89214", "type": "Role" }

3. Kliknij Grant admin consent for (Przyznaj zgodę administratora dla) Twojej organizacji.

1. W sekcji Zarządzaj kliknij Certyfikaty i obiekty tajne Nowy tajny klucz klienta.
2. Wpisz opis, wybierz okres ważności i kliknij Dodaj.
3. Skopiuj wartość tajnego klucza klienta i zapisz ją w bezpiecznym miejscu. Wartość jest wyświetlana tylko raz.

Ważne: przechowuj dane logowania do aplikacji w bezpiecznym miejscu. Jeśli dane logowania wyciekną, hakerzy mogą uzyskać dostęp do wszystkich Twoich danych Exchange.

Kliknij Overview (Przegląd) i zapisz te dane logowania:
