HTTPS Required - Microsoft requires the requesting application to be hosted via HTTPS. A FlexDeploy installation only using HTTP will not be able to use Microsoft OAuth.
Create the Application in Azure AD
Register a New App
Navigate to the Azure portal and select Azure Active Directory from the browser. Once there click on App Registrations and register a new app.
Add the Redirect URI
Give your app a name and set the web redirect URI.
This should be your FlexDeploy server with the following path /flexdeploy/rest/v2/oauth
Request Permissions
After clicking register copy the client id and tenant id on the home page of the application. Next click on API Permissions
On the API Permissions screen, click Add a Permission and select Microsoft Graph → Delegated Permissions.
You will need to add the following permissions:
User.Read
Mail.Send
Mail.ReadWrite (Only if you are configuring Email Approval)
You may need your admin to grant consent for the permissions above, which they can do by navigating to the same screen as above and hitting the currently disabled ‘Grant admin consent’ button
Add a Client Secret
Finally, navigate to Certificates & secrets on the left hand panel, create a client secret and copy that to safe location.
Be sure to copy the value of the secret. The secret id is not needed.
Update FlexDeploy System Settings
Match the Server Base URL
First, make sure your FlexDeploy Server Base Url in General Settings matches what you entered in Azure Application redirect.
Populate OAuth Information
Next, select Microsoft OAuth for the SMTP and/or IMAP auth type in Email Settings and add:
SMTP User - This is the user that will be logging in to graph with
Client Id
Client Secret
Tenant Id
SMTP From Address - The user must have permission to send from this address, or it won’t work.
Authorize and Validate
In order to authorize, you should login to http://outlook.com as the user you wish to authorize as first. Otherwise, especially if you are using SSO, it is likely that you will be authorizing as the wrong user. The idea is that when you click authorize, it will ask you who to login as, and you will select (or type) the same user that you have in the imap user / smtp user box that you are authorizing. You may need to use an incognito tab or guest window if your network signs you in automatically.
After populating the necessary fields, click either the Authorize or Re-Authorize buttons. At this point you will be re-directed to Microsoft to authorize FlexDeploy as the same user that you have in the imap user / smtp user box that you are authorizing. If everything is successful you should be redirected back to this page:
or
Once authorization is complete, you can test the configuration by clicking on the Test Email Configuration button located at the bottom next to Save.
Sends a test email to the logged in user's email address to validate the SMTP OAuth settings.
Reads the inbox of the Approval Reply Address to validate the IMAP OAuth settings.
If you authorized as the wrong user, you will get the error:
