   The Email Automation dialog box appears.

   • POP3
   • EWS
4. Specify details of the email server:
   1. For IMAP and POP3 server specify the following details:
      • Version 11.3.5.7, Version 11.3.1.13, Version 11.3.4.8 or later :
        • Host Name: Host name of the email server.
        • User Name: User name you want to use to connect to the email server.
        • Server uses secure connection (SSL): Select this option if the email account uses secured connection.
        • Port Number: Port that you want to use to connect to the email server.
        • Auth Type: Choose from the following authentication types:
          • Basic: Uses the username and password.
          • OAuth2 – Client credentials: Uses client credentials flow.

            See Authenticate an IMAP, POP or SMTP connection using OAuth

          • OAuth2 – Authorization code with PKCE: Uses authorization code with PKCE grant flow.

            See Microsoft identity platform and OAuth 2.0 authorization code flow

          Option	Description
          Basic	Enter the password for the username you provided.
          OAuth2 – Client credentials	Provide the following details: Client ID and Tenant ID: Enter the unique client and tenant IDs generated when you registered the application in the Microsoft Azure portal. Client secret: Enter the client secret that you generated for your app in the app registration portal.
          OAuth2 – Authorization code with PKCE	Provide the following details: Client ID and Tenant ID: Enter the unique client and tenant IDs generated when you registered the application in the Microsoft Azure portal. Redirect URI: The redirect URI in your Azure app registration portal. Connect: Click this option to sign into your account, accept the permissions requested to authenticate, and establish a connection with the OAuth server. Note: You must establish the connection only when you connect for the first time. Keep the following considerations in mind when you use authorization code with PKCE. Ensure that the redirect URL format is http://localhost:9090/callback In Redirect URL, only HTTP is supported. URL urn:ietf:wg:oauth:2.0:oob is required while configuring the PKCE on Azure portal. You can add only Mobile and desktop applications when you configure the platforms in Azure portal. The consent page appears only for the first time when you authenticate for the first time. However, when you run your email automation, each time, you are asked to sign in to your Microsoft account and provide the username and password. To log in to your Microsoft account, you must provide the same username that you provided in the Email Automation command to run the bots.

      • Note:

        • For attended email automation, use PKCE flow.
        • The email automation created using Version 11.3.5.7 (Basic and OAuth2.0) will not work in the environments where earlier versions of Enterprise 11 (prior to Version 11.3.5.7) clients are used. However, if the bot is not modified in Version 11.3.5.7, it will continue to work in the earlier versions. Any changes to the email command fields will update the internal structure, and the bots will not work in the earlier versions after these changes.
        • As a best practice, use credential variables for the client secret, password, and other related fields to avoid storing sensitive information.

        The above points also apply to Version 11.3.1.13 and Version 11.3.4.8.

      • Prior to Version 11.3.5.7, Version 11.3.1.13, and Version 11.3.4.8:
        • Host Name: Host name of the email server.
        • User Name: User name you want to use to connect to the email server.
        • Password: Password you want to use to connect to the email server.
        • Server uses secure connection: Select this option if the email account uses secured connection.
        • Port Number: Port that you want to use to connect to the email server
   2. For Exchange Web Services (EWS), specify the following details:
      • Domain Name: Domain name of the EWS server.
      • User Name: User name you want to use to connect to the email server.
      • Password: Password you want to use to connect to the email server.
      • Client ID and Tenant ID: Enter the unique client and tenant IDs generated when you registered the application in the Microsoft Azure portal. These fields are required for OAuth.
      • Exchange Version: Select an option from the list to specify the version of the EWS server you want to use.
      • Exchange Url: Specify the URL of the EWS server.

        You can click the Fetch option to populate the Exchange Url field based on the values you have provided in the User Name and Password fields.

5. Select an option to specify the emails to be deleted:
   • All: Deletes all emails.
   • Read: Deletes emails that are read.
