Configuring OAuth - Microsoft Office 365

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.

Open

Add the Redirect URI

Give your app a name and set the web redirect URI.

Open

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:

• IMAP.AccessAsUser.All

• offline_access

• SMTP.Send

• User.Read

Add a Client Secret, OR upload an X509 certificate.

Finally, navigate to Certificates & secrets on the left hand panel, create a client secret and copy that to safe location.

To upload an x509 certificate instead, click upload certificate. The same x509 certificate will be sent by FlexDeploy. In this case, use a certificate-type credential.

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 auth type in Email Settings and add:

1. SMTP Host Name - smtp.outlook.com

2. SMTP User

3. Client Id

4. Client Secret / Certificate

5. Tenant Id

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.

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.

Once you test

If you authorized as the wrong user, you will get the error:

Bad User is Authenticated But Not Connected

If you get that, reauthorize as the correct user, and then test again. Similarly, if you authorized as one user and need to authorize as a different user in the same session, then make sure to sign out of Microsoft first (usually this would be signing out of https://portal.microsoftonline.com). You may also want to run just this step with FlexDeploy from on Incognito or inprivate browser. Otherwise, the first user’s credentials will automatically be used with the authorization instead of prompting you to login as the second user. You will see this error when testing the email configuration:
