Guest users can’t see managed metadata values

Start time: February 2026
Published: 9 March 2026

Guest users in some tenants stopped seeing metadata values (terms) set on documents which they have access to. The issue affects not only MetaShare, but SharePoint sites as well. We’re in contact with Microsoft regarding the issue. It seems that a recent change in SharePoint changed how values are retrieved from Taxonomy Hidden List. Current solution/workaround seems to be adding guest users to a group that has read permissions on Taxonomy Hidden List.

Update: 2026-03-11

The issue seems now to be resolved by Microsoft. We’ll continue monitoring the issue and verify if the fix reached all affected tenants.
