Issue: When opening Excel files stored in SharePoint, users may encounter the following security warning in Microsoft Office:
"This content presents a potential security issue. Do you trust this content?"
This warning typically appears when accessing Excel files via a button or link in Active Workpapers that point to SharePoint-hosted documents. The warning may appear even when the content is safe.
Steps to Resolve:
Safe to Proceed: If the warning includes a trusted URL (such as an Active Workpapers SharePoint link), users can safely click Yes to proceed.
Microsoft's Acknowledgement: This issue has been identified by Microsoft as a known false-positive security warning. It appears when Excel files are opened from SharePoint through integrations like Active Workpapers.
Update Excel Version: Microsoft has resolved this issue in Excel version 2406 and higher. Encourage users to ensure they are using the latest version of Excel by following these steps:
Open any Office application (e.g., Excel).
Go to File > Account > Update Options.
Click Update Now to download and install the latest Office updates.
Temporary Workaround (if unable to update):
Users can manually select Yes on the security warning to proceed each time they encounter it. This is safe for links generated by Active Workpapers.
