- **[Connect Einstein Activity Capture to Microsoft Exchange using User-Level Authentication](https://help.salesforce.com/s/articleView?id=sales.eac_setup_ms_exchange_user_level_connection.htm&release=264.0.0&type=5)**  
    The user-level authentication method is available for Microsoft Exchange on-premises servers and Microsoft Office 365. After users are assigned to Einstein Activity Capture, they’re prompted to connect their Microsoft account to Salesforce.
- **[Connect to Einstein Activity Capture with a Microsoft Exchange Service Account](https://help.salesforce.com/s/articleView?id=sales.aac_setup_service_account_parent.htm&release=264.0.0&type=5)**  
    The service account authentication method is available for Microsoft Exchange on-premises servers. A service account can help you scope authentication to a specific set of users and set up all Einstein Activity Capture users at the same time. The Salesforce admin works with their Exchange admin to create a service account with the impersonation role and give Salesforce access to the service account user’s data. Follow the steps based on the supported server that your company uses.
- **[Preparing to Connect to Einstein Activity Capture with a Microsoft Exchange Service Account](https://help.salesforce.com/s/articleView?id=sales.aac_setup_service_account_prep.htm&release=264.0.0&type=5)**  
    Before you can set up Einstein Activity Capture by using the service account connection method, make sure that you work with your Exchange admin to get things ready on the Microsoft side.
- **[Use a Service Account to Connect an Exchange On-Premises Server to Einstein Activity Capture](https://help.salesforce.com/s/articleView?id=sales.aac_setup_service_account_on_prem.htm&release=264.0.0&type=5)**  
    If your company uses Microsoft Exchange 2019, 2016, or 2013 on-premises, you can connect to Einstein Activity Capture by using a service account. The Salesforce admin works with their Exchange admin to create a service account with the impersonation role and give Salesforce access to the service account user’s data. By using a service account, you can scope authentication to a specific set of users and set up all Einstein Activity Capture users at the same time.
- **[Connect Salesforce to Your Microsoft Exchange Endpoint](https://help.salesforce.com/s/articleView?id=sales.aac_setup_manual_connection.htm&release=264.0.0&type=5)**  
    If your Exchange Web Service (EWS) isn’t exposed externally because the Microsoft Autodiscover setting isn’t on, Einstein Activity Capture or Inbox can’t find your Microsoft Exchange account. Manually connect your Microsoft Exchange endpoint to Salesforce so that your Microsoft Exchange users can benefit from Einstein Activity Capture or Inbox.
- **[Network Connection](https://help.salesforce.com/s/articleView?id=sales.aac_setup_allow_access.htm&release=264.0.0&type=5)**  
    When setting up Einstein Activity Capture with a Microsoft Exchange on-premises server (2019, 2016, or 2013) or Microsoft Office 365, make sure that you allow the necessary network access.
