  6. Configure BEMS to communicate with the Microsoft Exchange Server, Microsoft Office 365, or hybrid environment

Configure
BEMS
 to communicate with the
Microsoft Exchange Server
,
Microsoft Office 365
, or hybrid environment

If your
BEMS
 environment uses
Microsoft Graph
 to communicate with
Microsoft Office 365
, see Configure BEMS to communicate with a Microsoft Office 365 environment using Microsoft Graph API. You must allow
BEMS
 to authenticate to
Microsoft Exchange Server
 or
Microsoft Office 365
 to access users’ mailboxes and send notifications to users’ devices when new email is received on the device. A hybrid modern authentication environment (for example, on-premises
Microsoft Exchange Server
 and
Microsoft Office 365
), allows the on-premises
Microsoft Exchange Server
 to use a more secure user authentication and authorization by consuming OAuth access tokens obtained from the cloud. For more information on how to configure an on-premises
Microsoft Exchange Server
 to use hybrid modern authentication, visit configure-exchange-server-for-hybrid-modern-authentication?view=o365-worldwide.

    BEMS
     with OAuth tokens to authenticate to
    Microsoft Office 365
    . In a hybrid environment, authenticates to on-premises
    Microsoft Exchange Server
    **
    .
    1. In the
      Authentication Authority
       field, enter the Authentication Server URL that
      BEMS
       accesses and retrieve the OAuth token for authentication with
      Microsoft Office 365
       (for example, https://login.microsoftonline.com/<
      tenantname
      >). By default, the field is prepopulated with https://login.microsoftonline.com/common.
    2. In the
      Client Application ID
       field, enter the
      Entra
       app ID for the credential authentication. For instructions, see the App ID for BEMS using credential authentication.
    3. In the
      Server Name
       field, enter the FQDN of the
      Microsoft Office 365
       server. By default, the field is prepopulated with https://outlook.office365.com .
    4. In the
      Redirect URI
       field, enter the URL that the IDP redirects the administrator to when the client app ID is authorized and the authentication tokens are provided. If you remotely log in to the computer that hosts the
      BEMS
       and perform the configuration from the computer's browser, enter
      https://localhost:8443/PassiveAuth
      ), otherwise enter
      https://<FQDN of the computer that hosts the BEMS instance in lower case
      >:8443/PassiveAuth
      The URI must be the same URI as the
      BEMS
       URI and whitelisted in the
      Entra
       portal for the application ID.
    5. Click
      Login
      .
    6. Enter the credentials for the service account.
    7. Click
      OK
       to acknowledge that the authentication tokens were obtained.
    8. Important:
      BEMS
       doesn't automatically refresh the OAuth tokens. Repeat steps e to g to refresh the OAuth tokens. The tokens expiration time depends on your tenant policy (by default, the token expiration is 90 days). When the OAuth tokens expire, email notifications on the users' devices stop. The OAuth token expiration is displayed after you log in to the IDP.
    *
     If
    BEMS
     uses Credential Authentication to authenticate to a
    Microsoft Office 365
     environment, you must enable Modern Authentication. For more information, visit deprecation-of-basic-authentication-exchange-online. 
    **
     The
    Microsoft Exchange Server
     on-premises must be configured to use hybrid modern authentication. For more information, visit configure-exchange-server-for-hybrid-modern-authentication?view=o365-worldwide. 
  4. In a
    Microsoft Office 365
     environment that uses Credential or Client certificate authentication, enable Modern Authentication and use mutual TLS authentication. Complete the following steps:
    1. Select the
      Enable Modern Authentication
       checkbox.
    2. If your environment uses Client certificate authentication, in the
      Authentication Authority
       field, enter the Authentication Server URL that
      BEMS
       accesses and retrieve the OAuth token for authentication with
      Microsoft Office 365
       (for example, https://login.microsoftonline.com/<
      tenantname
      > or https://login.microsoftonline.com/<
      tenantid
      >). By default, the field is prepopulated with https://login.microsoftonline.com/common.
    3. In the
      Client Application ID
       field, enter one of the following
      Entra
       app IDs depending on the authentication type you selected:
    4. In the
      Server Name
       field, enter the FQDN of the
      Microsoft Office 365
       server. By default, the field is prepopulated with https://outlook.office365.com.
    5. Optionally, select the
      Use Credentials if Modern Authentication fails
       check box to allow
      BEMS
       to communicate with
      Microsoft Office 365
       in the event that
      BEMS
       can't access the modern authentication source. When you select this check box, you must provide the
      BEMS
       service account credentials.
    6. Optionally, select the
      Use Mutual TLS Authentication
       check box to allow
      BEMS
       to respond to mutual TLS authentication requests. This step requires that the mutual TLS certificate is imported into
      BEMS
      . For instructions, see Import the trusted mutual TLS certificates into the BEMS keystore.
    When you configure Modern Authentication, all nodes use the specified configuration.
  5. Under the
    Autodiscover and Exchange Options
     section, complete one of the following actions:
    Task
    Steps
    Override Autodiscover URL
    If you select to override the autodiscover process,
    BEMS
     uses the override URL to obtain user information from the
    Microsoft Exchange Server
     or
    Microsoft Office 365
    . For more information about best practices when enabling autodiscover, see Best practice: Enabling autodiscovery.
    1. Select the
      Override Autodiscover URL
       checkbox.
    2. In the
      Autodiscover URL
       Override Autodiscover field, type the autodiscover endpoint (for example, https://autodiscover<
      domain
      >.com/autodiscover/autodiscover.svc).
    Autodiscover and
    Microsoft Exchange Server
     options
    1. Select the
      Swap ordering of <
      domain.com
      >/autodiscover and autodiscover. <
      domain.com
      >/autodiscover
       check box to assist in resolving the autodiscover URL. Consider selecting this option if the order results in timeouts or other failures.
    2. Optionally, modify the
      TCP Connect timeout for Autodiscover url (milliseconds)
       field as required to prevent failures when autodiscovery takes too long. By default, the timeout is set to 120000. The recommended timeout for the Autodiscover url is between 5000 milliseconds (5 seconds) and 120000 milliseconds (120 seconds).
    3. By default, the
      Enable SCP record lookup
       checkbox is selected. If you clear the checkbox,
      BEMS
       does not perform a
      Microsoft Active Directory
       lookup of Autodiscover URLs. This option is not available when Override Autodiscover URL is selected.
    4. Optionally, select the
      Use SSL connection when doing SCP lookup
       check box to allow
      BEMS
       to communicate with the
      Microsoft Active Directory
       using SSL. If you enable this feature, you must import the
      Microsoft Active Directory
       certificate to each computer that hosts an instance of
      BEMS
      . This option is not available when Override Autodiscover URL is selected.
    5. By default, the
      Enforce SSL Certificate validation when communicating with Microsoft Exchange and LDAP server
       check box is selected. If you clear this setting and use an un-trusted certificate, then the connection to the on-premises
      Microsoft Exchange Server
       fails.
    6. By default, the
      Allow HTTP redirection and DNS SRV record
       check box is selected. If you clear the checkbox, you disable HTTP Redirection and DNS SRV record lookups for retrieving the Autodiscover URL when discovering users for
      BlackBerry Work
      Push Notifications
      .
    7. Optionally, select the
      Force re-autodiscover of user on all Microsoft Exchange errors
       checkbox to force
      BEMS
       to perform the autodiscover again for the user when the
      Microsoft Exchange Server
       or
      Microsoft Office 365
       returns an error message.
  6. In the
    End User Email Address
     field, type an email address to test connectivity to the
    Microsoft Exchange Server
     or
    Microsoft Office 365
     using the service account. Click
    Test
    . You can delete the email address after you complete the test.
    If the service account is correctly configured and the test fails,
    BEMS
     is attempting to communicate with an
    Microsoft Exchange Server
     that is not using a trusted SSL Certificate. If your
    Microsoft Exchange Server
     is not set up to use a trusted SSL certificate, see "Importing CA certificates for BEMS" in the BEM-Core content.
