In SharePoint Online, you can customize the error message that appears when a user does not have permission to access a specific library. By default, SharePoint displays a generic error message, but you can modify it to provide a more informative and user-friendly message.
To customize the error message in SharePoint Online, follow these steps:
- Navigate to the SharePoint site where the library is located.
- Click on the gear icon in the upper-right corner to open the Settings menu.
- Select "Site Settings" from the dropdown menu.
- Under the "Site Collection Administration" section, click on "Site collection features."
- Activate the "SharePoint Server Publishing Infrastructure" feature if it is not already activated. This feature provides additional customization options for the site.
- Go back to the Site Settings page, and under the "Site Collection Administration" section, click on "Site collection features" again.
- Activate the "SharePoint Server Publishing" feature.
- After activating the above features, go back to the Site Settings page, and under the "Site Actions" section, click on "Site collection features" once more.
- Activate the "SharePoint Server Publishing" feature.
- Go back to the site's homepage and click on the "Page" tab in the ribbon.
- Click on "Edit" to edit the page where the library button is located.
- Select the button and click on the "Insert" tab in the ribbon.
- Click on "Link" to insert a link into the button.
- In the link properties, enter the URL of the library that users do not have permission to access.
- Append "?NoRedirect=True" to the end of the URL.
- Save and publish the page.
Now, when a user without permission clicks on the button, they will see a custom error message like "Access denied" or "You don't have permission to view this library" instead of the generic error message. This helps provide more clarity to users who do not have the necessary permissions.
Please note that the above steps require the SharePoint Server Publishing Infrastructure and SharePoint Server Publishing features to be enabled. Additionally, customization options may vary depending on the specific version and configuration of SharePoint Online in your organization.
