About this tag
The fprpc block tag covers Microsoft 365 Apps for Windows version 2508 and its default blocking of FrontPage Remote Procedure Call (FPRPC) file access. The related guidance focuses on finding Office and SharePoint workflows that still depend on legacy web-folder paths, including Trusted Locations and older Office automation, before the August 26, 2025 release reaches users.

This archive is useful for administrators planning compatibility checks and updating inherited FrontPage-era publishing or file-open workflows.
