Configure SharePoint on-premises for harmon.ie access

harmon.ie can access SharePoint on-premises sites using basic authentication, forms authentication, NTLM authentication and Kerberos authentication. For custom authentication methods, contact support@harmon.ie.

There are three configuration requirements for accessing a SharePoint on-premises server from Outlook:

1. Web Service access

harmon.ie uses the Windows SharePoint Services Web Services to connect to a SharePoint site. You can verify they are accessible by visiting http://<SharePoint Server>/_vti_bin/sites.asmx.

2. Browsing subsites

The SharePoint administrator needs to grant Browse Directories permission for users to view subsites:

1. Open the Permission Levels page, from Site Settings > Site permissions > Permission Levels.
2. Click the permission level that you want to edit.
3. Check Permissions > Site Permissions > Browse Directories.
4. Click Submit.

3. Enabling client integration

Client integration is disabled by default when you use forms-based authentication, because client integration does not support forms-based authentication natively. To enable client integration:

1. Open the Permission Levels page, as explained above.
2. Click the permission level that you want to edit.
3. Check Permissions > Site Permissions > Use Client Integration Features.
4. Click Submit.
