We saw, creating a term set from the Navigation Settings in the previous articles. Now, let us see, how to make use of the same TermSet to the other site collections with read permission. This term set can be used to Re-use, Pin etc., Users cannot modify the terms inside this term set from other site collections.
Make sure that you’re a member of the Owners SharePoint group on the site that contains the term set.
On the Site Settings page, in the Site Administration section, select Term store management.
In the Term Store Management Tool, select the group that contains all term sets within the site collection.
In the Site Collection Access section, type the URLs of the site collections that you want to give access to the term sets.
