System Requirements and Technical Considerations

Infrastructure

You can use the SuiteProjects Pro <> Exchange integration with an on-premise Windows domain network configuration, a cloud-based environment, or an hybrid configuration.

Review the following guidelines:

• Effective October 1, 2026, you may not be able to use EIM to integrate SuiteProjects Pro with Exchange Online. Microsoft will start blocking Exchange Web Services (EWS) requests from non-Microsoft apps to Exchange Online. For more information about Microsoft's plan, see Deprecation of Exchange Web Services in Exchange Online.

• Exchange Server 2016 reached end of extended support in October 2025. EIM does not officially support later versions, such as Exchange Server 2019 or SE. The integration between SuiteProjects Pro and later versions of Exchange Server, such as 2019 or SE, may work but we make no guarantees.

• If Active Directory is not available, you need to set up mapping between SuiteProjects Pro and Exchange Server users manually.

• If some or all mailboxes are stored in an on-premise Exchange organization, you should install EIM on a separate server or workstation on the same network as the company's Exchange server. This ensures the integration has access to Active Directory to query users, but does not store the integration configuration on the same server.

• If EIM is set up on a remote server outside the company network, the integration typically needs VPN access to the company network to be able to interface with the Exchange server.

System Requirements

The following requirements must be met to install, configure, and run EIM:

• Operating System

  • Microsoft Windows Server 2016 or 2019

    Note:

    EIM may run on later versions of Windows Server, such as 2022 or 2025, but we make no guarantees.

  • Microsoft Windows 10 or 11

• Microsoft .NET Framework Version 4.7.2.

  Note:

  The EIM installer automatically downloads it if it is not installed on your computer.

• RAM 1GB or more.

Communication Interfaces

EIM use the following communication interfaces:

• SuiteProjects Pro XML API to transfer information from and to SuiteProjects Pro over a secure layer using the HTTPS protocol (port 443). No incoming ports need to be opened in the firewall.

• Active Directory Services Interface (ADSI) and Lightweight Directory Access Protocol (LDAP) to communicate with on-premise Active Directory and retrieve the user information (email address and home mailbox server) required to map Exchange user mailboxes (and associated Active Directory user accounts) with SuiteProjects Pro user records.

• Exchange Web Services (EWS) to connect to Microsoft Exchange and create calendar events in user mailboxes.

  Important:

  Note the following compatibility guidelines:

  • Exchange Integration Manager 5.0 or later version does not support WebDAV.

  • Microsoft no longer supports Basic authentication for EWS to access Exchange Online. Exchange Integration Manager 5.1 introduced support for using OAuth 2.0 to connect to Exchange Online using EWS. To configure and run the integration between SuiteProjects Pro and Microsoft Exchange Online, you must use Exchange Integration Manager 5.1 or later version and register Exchange Integration Manager with Microsoft Entra ID. See Registering Exchange Integration Manager With Microsoft Identity Platform.

Role Permissions

To set up and run SuiteProjects Pro <> Exchange integration you must have user accounts with the following permissions:
