How to change to oAuth2 Authentication for Connect to Mail

Question:
How can I best switch over my Connect to Mail configurations to using OAuth2 authentication?

Answer:
Please refer to the following guide on how to enable OAuth2 authentication for Connect to Mail:

Background Information
Microsoft has stated Basic Authentication is officially announced to be deprecated effective October 1, 2022. After this date, it will no longer be possible to configure Basic Authentication for Exchange Online systems. 
With the upcoming deprecation, it'll become necessary to implement OAuth2 authentication to ensure that your Connect to Mail jobs remain functional. Making the changes can vary depending on your situation with which DocuWare system you are using. Please consider the following scenarios with respect to how to begin using OAuth2.

For additional information regarding the deprecation of basic authentication, please see: Deprecation of basic authentication/exchange-online

***Note: Even when Basic Authentication is disabled, SMTP Auth will still be available.***

For Cloud Customers without creating a self-created app in Azure
There is no need to create a Mail Service configuration since we already deliver everything for connecting to your Office 365 mail account with OAuth2. Go to your “General Email” plugin and connect directly with your Office 365 account by selecting the “Exchange Online” option.


For Cloud Customers using a self-created app in Azure
If you want to connect to Office 365 with your self-created app, follow the steps below:

Register the OAuth app in your organization's Azure Active Directory

1. Switch to your organization's app registration and click on the New registration plus icon [https://portal.azure.com/#blade/Microsoft_AAD_IAM/ActiveDirectoryMenuBlade/RegisteredApps]
   
2. Give it a display name and provide a Redirect URI such as "https://my-company.com/DocuWare/Settings?link=MailCapture" 
   Note: The Redirect URI is case-sensitive and must be accessible from the internet. This redirect url will be called by Microsoft after a user has successfully authenticated
   
   
3. Open the "Authentication" menu from the left and scroll down to the header "Implicit grant". Please ensure both "Access tokens" and "ID tokens" are checked, then save your changes.
   
4. Switch to the "Certificates & secrets" menu and create a new client secret. Please store this client's secret safely. We will need it later while registering the app in DocuWare Mail Services.
5. Next, on the app registration menu, select "API permissions" and add a new permission.
   • Select here "Microsoft Graph" from the Microsoft APIs and click on "Delegated permissions"
   • Add the following permissions below and store your changes: 
     • offline_access
     • openid
     • EWS.AccessAsUser.All
     • User.Read
       
6. Finally, click "Grant admin consent for YOUR COMPANY NAME" from the overview of configured permissions. This is step is optional. If you don't grant access now, an organization administrator must do it afterward. Otherwise, the user won't be able to grant permission for Connect to Mail.
    
7. Congratulations! You now have successfully configured your personal OAuth2 app. Switch to the overview and copy the values of "Application (client) ID," "OAuth 2.0 authorization endpoint (v2)," and "OAuth 2.0 token endpoint (v2)" (from the Endpoints menu). We will need them for registering in the mail services plugin
   

1. From the Azure Active Directory, open the blade "Enterprise applications"
2. Next, move to "Consent and permissions" [https://portal.azure.com/?l=en.en-us#blade/Microsoft_AAD_IAM/ConsentPoliciesMenuBlade/UserSettings]
3. In the submenu "User consent settings (Preview)," select "Allow user consent for apps from verified publishers, for selected permissions (Recommended)"
   
4. Click-on permissions are classified as low impact and the Exchange Web Services APIs. It should be displayed as the following:
   
   Permissions
   EWS.AccessAsUse.All
   Offline_access
   profile
   openid
   email
   User.Read
   
   
5. Remember to save your changes, and users will now be able to grant access to this app. Please proceed to the following section.

1. Open the DocuWare Configurations [https://your-DocuWare/DocuWare/Settings]
2. Open the Mail Service plugin and select create a new Exchange mail service
3. Make sure the Authentication type is set to "Use OAuth2 Authentication"
4. Fill in all details that you've noted down while creating the new Azure Active Directory app registration.
5. Don't forget to enter the exact same Redirect URI from the registration (e.g. "https://my-company.com/DocuWare/Settings?link=MailCapture")
6. It may be required to change the Exchange Web Services URL.
7. Store and save your configuration
8. Now, you're able to use this new Exchange mail service connection in the General Email plugin.

1. Open a browser and navigate to the Azure Active Directory admin center, and log in using a personal account (aka: Microsoft Account) or Work or School Account.
2. Select Azure Active Directory in the left-hand navigation, then select App registrations under Manage.
