Where to create the “harmon.ie Files” library
The harmon.ie Files library should be created in one of the following locations:
- Under the Root Site – Recommended for a simple, centralized setup. Requires that all users can access the root site.
- Under a “harmon.ie Admin” Subsite – Choose this option if root site access is restricted for some users.
1. (Optional) Create a “harmon.ie Admin” subsite:
If you don’t want or can’t create the harmon.ie Files library in the root site, you may create it under a subsite.
a. Create subsite:
- In the root site, go to Settings > Site contents > New > Subsite.
- Set Title to harmon.ie Admin. The name cannot be changed.
- Set URL name to harmon.ie Admin. The URL name cannot be changed.

b. Set permissions:
- Create or use an existing SharePoint group to specify the harmon.ie Admins.
- Use unique permissions for the subsite and remove all users except harmon.ie Admins and site owners.
c. (Recommended) Hide the “harmon.ie Admin” subsite:
- Remove it from the navigation bar.
- Exclude it from search indexing:
- Go to Site settings > Search and Offline Availability.

2. Create the “harmon.ie Files” document library

- Name the library harmon.ie Files. The name cannot be changed.

- Grant read-only access for all users: Add the group Everyone except external users with Read permissions.
- Grant edit access for harmon.ie Admins: Create or use an existing SharePoint group to specify the harmon.ie Admins. Add this group with Edit permissions.
