הגדרת אפליקציית Azure ל-Exchange Online

1. נכנסים לפורטל Azure כאדמינים.
2. לוחצים על Cloud Shell Powershell.
3. אם מוצגת בקשה, יוצרים חשבון אחסון ומאשרים את הגדרות ברירת המחדל.
4. כדי ליצור את האפליקציה, מזינים את הפקודה הבאה ולוחצים על Enter:

   Install-Module Microsoft.Graph -Scope CurrentUser

5. אם מופיעה בקשה להתקין ממאגר לא מהימן, מזינים Y לוחצים על Enter.
6. מעתיקים את קטע הקוד הבא, מדביקים אותו ב-PowerShell ולוחצים על Enter.

3. שימו לב לפרטי הכניסה הבאים ושמרו אותם במקום מאובטח. אם פרטי הכניסה יודלפו, האקרים יוכלו לגשת לכל הנתונים שלכם ב-Exchange Online.
   • סוד לקוח
   • מזהה האפליקציה (אפליקציית הלקוח)
   • מזהה הספרייה (הדייר)

מטעמי אבטחה, מומלץ לרשום את האפליקציה החדשה כדייר יחיד.

1. נכנסים לפורטל Azure כאדמינים.
2. ב-Azure Services, עוברים אל App registrations.
3. לוחצים על New Registration (רישום חדש) ומזינים שם לאפליקציה (לדוגמה, Advanced import app).
4. בקטע סוגי חשבונות נתמכים, לוחצים על חשבונות בספרייה הארגונית הזו בלבד כדי ליצור אפליקציה לדייר יחיד.
5. לוחצים על הרשמה.

בוחרים אחת מהאפשרויות האלה:

אפשרות 1: הוספת הרשאות באופן ידני

1. בצד, בקטע Manage (ניהול), לוחצים על API permissions (הרשאות API).
2. לוחצים על Add a permission (הוספת הרשאה) Microsoft APIs (ממשקי API של מיקרוסופט) Microsoft Graph.
3. בקטע הרשאות לאפליקציה, בוחרים:
   • Calendars.Read
   • Contacts.Read
   • Directory.Read.All
   • Group-Conversation.Read.All
   • Mail.Read
   • MailboxFolder.Read.All
   • MailboxItem.Export.All
   • MailboxItem.Read.All
   • MailboxSettings.Read
   • Tasks.Read.All
   • User.Read.All
4. לוחצים על Grant admin consent for your organization (מתן הסכמה של אדמין לארגון).

אפשרות 2: עריכת המניפסט של האפליקציה

1. פותחים את המניפסט של האפליקציה.
2. עוברים אל "resourceAccess" : [ ] ובוחרים אפשרות:
   • אם כבר יש ערך ב-"resourceAccess" : [ ], מוסיפים פסיק ואז מדביקים את בלוק הקוד הבא.
   • אם אין ערך ל-"resourceAccess" : [ ], מעתיקים ומדביקים את קטע הקוד הבא.

   { "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": "f10e1f91-74ed-437f-a6fd-d6ae88e26c1f", "type": "Role" },

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

3. לוחצים על Grant admin consent for your organization (מתן הסכמה של אדמין לארגון).

1. בצד, בקטע Manage, לוחצים על Certificates & secrets New client secret.
2. מזינים תיאור, בוחרים תקופת תפוגה ולוחצים על הוספה.
3. מעתיקים את Client secret value ושומרים אותו במקום מאובטח. הערך מוצג רק פעם אחת.

חשוב: צריך לאחסן את פרטי הכניסה של האפליקציה באופן מאובטח. אם פרטי הכניסה יודלפו, האקרים יוכלו לגשת לכל הנתונים שלכם ב-Exchange.

לוחצים על Overview ורושמים במקום בטוח את פרטי הכניסה הבאים:

• מזהה האפליקציה (אפליקציית הלקוח)
• מזהה הספרייה (הדייר)
