Prerequisites and compatibility

This article lists CDM’s minimum software, hardware, and operating system requirements, along with other essential steps you should consider before deploying CDM.

System requirements

Essential Runtime components

You can’t deploy CDM successfully without first installing the following runtime components:

List of trusted URLs

You’ll need to add some URLs to your trusted list to avoid CDM’s traffic to Microsoft 365 or Bifrost (the IAM Cloud API) from being blocked. This is especially relevant when:

  • Your organization uses firewalls, proxies, web filters, or security software

  • Your Microsoft 365 tenant is based in a US Government Community Cloud (GCC), GCC High, or DoD

  • Your Microsoft 365 tenant is based in Germany or China

  • Your Microsoft 365 tenant is multi-geo-enabled

Guidance for organizations using network or security controls

If your organization uses firewalls, proxies, web filters, or security software, you’ll need to whitelist the following URLs:

  • https://graph.microsoft.com (Global)

  • https://login.microsoftonline.com

  • https://*.iamcloud.net: This is a wildcard domain. Ensure that traffic to this domain is allowed through your network or security controls.

    https://<tenant-name>.sharepoint.com: Replace <tenant-name> with your SharePoint Online tenant name.

  • https://<tenant-name>-my.sharepoint.com: This URL only applies to personal OneDrive sites. Replace <tenant-name> with your SharePoint Online tenant name.

Guidance for US government environments, Germany, or China

If your Microsoft 365 tenant is based in a US Government Community Cloud (GCC), GCC High, or DoD, Germany, or China, and it uses firewalls, proxies, web filtering, or security software, you’ll need to whitelist the following URLs:

  • https://login.microsoftonline.us (US Government GCC, GCC High, DoD)

  • https://login-us.microsoftonline.com (US Government Cloud)

  • https://login.microsoftonline.de (Germany)

  • https://login.partner.microsoftonline.cn (China 21Vianet)

  • https://login.chinacloudapi.cn (China 21Vianet)

Guidance for multi-geo environments

In multi-geo environments, SharePoint and OneDrive URLs may also include regional geo-locations. For example:

  • https://<tenant-name>nam.sharepoint.com

  • https://<tenant-name>eur.sharepoint.com

Therefore, if your organization uses firewalls, proxies, web filtering, or security software, please whitelist regional SharePoint URLs associated with your multi-geo locations.

Exclusion policy

If your Microsoft 365 tenant uses security software, you’ll need to add specific paths to your organization’s exclusion policy. These include the following:

  • C:\Program Files\IAM Cloud\Cloud Drive Mapper: The Cloud Drive Mapper folder contains application binaries essential for CDM to function.

  • C:\Windows\Temp\IAM Technology Group Limited\Cloud Drive Mapper: The Cloud Drive Mapper folder also contains temporary files that the CDM installer uses during installation, upgrade, and uninstallation.

  • %temp%\IAMCloud: The IAMCloud folder contains temporary files for the CDM.CoAuthHandler.exe, which are used for co-authoring in Microsoft Office apps.

  • C:\Program Data\IAM Cloud\Cloud Drive Mapper: The Cloud Drive Mapper folder contains gRPC domain socket files essential for CDM to function.

  • %localappdata%\IAM Cloud\Cloud Drive Mapper: The Cloud Drive Mapper folder contains CDM log files, the local database, and session data required by CDM to function correctly.

Tenant-level Microsoft 365 integration

Get your Entra admin to approve CDM's integration with your Microsoft 365 tenant.

  • If you have Entra admin permissions, click here and follow the steps.

  • If you don’t have Entra admin permissions and work in a large organization, request admin approval promptly. For step-by-step instructions, see Grant admin consent to CDM.
