The direct method to connect to a resource to Microsoft 365 or Exchange is described here. A more advanced method to connect to a resource to Microsoft 365 or Exchange using Delegate access is described here. In some business environments, the way of directly connecting to resource calendars is not allowed without the permission of the Microsoft 365 or Exchange administrator. This could be due to enterprise IT policy or other restrictions. For example, the user is not allowed to give consent to the app and as a result, the app is not able to connect to the 0365 or Exchange resource. In this scenario, the user must send the approval request to the 0365 or Exchange administrator. Then the user can consent to the app to connect to the resource, once the admin approves the request. 

1. The admin can restrict the user to give consent to the app through the Azure admin portal. Then they need admin approval before using the app.
2. The user/resource can send the approval request to the admin by following these steps.
3. Open the Meeting Room Schedule app, Settings, Calendar connection, Exchange/0365, enter the resource credentials and press Save & Exit.
4. Copy the code from the resulting popup and press OK
5. Enter the code in the Microsoft popup in the browser and press Next.
6. Enter the resource credentials in the following popup and sign in.
7. At this stage, there are two possibilities.
   1. user/resource can send the approval request to the admin
   2. user/resource can send the approval request to the admin

 

User/Resource can send the approval request to the admin

1. Microsoft warns that the admin approval is required and displays the approval request. Enter the justification in the given field and press Request approval.
2. Microsoft will send the approval request to the admin.

 

User/Resource cannot send the approval request to the admin

1. Microsoft warns the user if he cannot send the approval request to the admin.
2. The admin can enable the users to send the approval requests to the admin.
3. Go to Azure admin portal, Enterprise applications, Consent and permissions, Admin consent settings. Find “Users can request admin consent to apps they are unable to consent to” under Admin consent requests and select Yes. Press Save to save the changes.
4. Repeat the steps from 1 to 6 above, from the main chapter, and send the approval request to the admin.

 

Approval request to the admin

1. Microsoft will send the approval request to the admin via email.
2. Click on Review permissions and consent
3. Review the permissions request and press Accept
4. Now the user/resource can sign in and use the Meeting Room Schedule application. Repeat steps from 1 to 6 above from the main chapter.
