Latest Message<\/th>\nTitle: Users may be unable to edit pages using SharePoint Designer<\/p>\n

User impact: Users may be unable to edit pages using SharePoint Designer.<\/p>\n

More info: Due to issues with the SharePoint Online Designer API, impacted users will need to utilize the following steps for updating SharePoint Online pages:<\/p>\n

1. Ensure the DenyACP aka NoScript security protection is currently off for the site
2. Download the ASPX file
3. Make edits to the aspx file as necessary using a text editor other than SP Designer or Visual Studio.
4. Upload the ASPX file<\/p>\n

Please note that step four will be impacted by the Support for Content Security Policy (CSP) in SharePoint Online, of which more details can be found at the following link:
learn.microsoft.com\/en-us\/sharepoint\/dev\/spfx\/content-securty-policy-trusted-script-sources<\/a><\/p>\n

Final status: We’ve determined that the API that allows editing within SharePoint Online Designer entered a problematic configuration state preventing us from restoring it. Users will need to utilize the steps outlined in the More Info portion of this communication for updating SharePoint Online pages. Users continuing to encounter problems editing SharePoint Online pages should contact one of our support representatives so we can continue our investigation into the problem.<\/p>\n

Scope of impact: This issue may prevent any user from editing SharePoint Online pages using SharePoint Designer.<\/p>\n

Start time: Wednesday, May 13, 2026, at 6:01 PM UTC<\/p>\n

This is the final update for the event.<\/td>\n<\/tr>\n
