How to Stop Acrobat from Prompting for SharePoint Credentials
Question details
Users need to prevent Acrobat XI Pro from continuously asking for login credentials when accessing files hosted on SharePoint.
- Product
- Adobe Acrobat XI Pro / SharePoint
- Device & OS
- Windows
- Scenario
- Opening PDF files directly from SharePoint or through Windows File Explorer.
- Observed behavior
- Acrobat XI Pro repeatedly prompts the user for SharePoint credentials, even though the PDF documents ultimately open successfully.
Verify that your Office 365 or SharePoint account is active and ensure you have administrative permissions on your Windows device to modify internet security settings.
Configure Windows Trusted Sites and Adobe Integration Settings
Adding your SharePoint URL to your Windows Trusted Sites and verifying Acrobat's SharePoint authentication settings resolves the most common cause of repeated credential prompts.
Acrobat relies on Windows internet settings to authenticate with SharePoint. When the SharePoint site is not recognized as a trusted source, the security integration continuously asks for credentials.
Click the Windows Start menu, search for 'Internet Options', and open the control panel utility.
Navigate to the 'Security' tab, select 'Trusted sites', and click the 'Sites' button. Type your SharePoint URL (e.g., https://yourcompany.sharepoint.com) and click 'Add'.
While still in the 'Security' tab with 'Trusted sites' selected, click 'Custom level'. Scroll to the bottom to 'User Authentication' and select 'Automatic logon with current user name and password'.
Open Acrobat XI Pro, go to Edit > Preferences > Tracker (or SharePoint integration settings, if available), and ensure the correct server authentication details are mapped.
Clear Stored Credentials in Windows Credential Manager
Clear outdated or corrupted SharePoint credentials stored in Windows that may be forcing Acrobat to prompt for new logins.
Read and Edit PDFs Seamlessly with WPS Office
If Acrobat continues to struggle with complex SharePoint integrations, consider switching to WPS Office. It offers a lightweight, robust PDF reader and editor that integrates effortlessly into your workflow, completely free from repetitive credential loops.
- 1. Download WPS Office: Visit the official WPS website and download the free WPS Office suite.
- 2. Install and Open: Run the installer. Once installed, launch the WPS Office application.
- 3. Open Your PDF: Drag and drop your PDF into the WPS workspace or use the 'Open' menu to bypass third-party authentication bugs.
Frequently Asked Questions
Why does Acrobat XI Pro repeatedly ask for my SharePoint password?
This happens when the authentication token between Windows, SharePoint, and Acrobat expires or fails to pass through correctly. It is usually caused by the SharePoint domain not being listed as a Trusted Site in your Windows internet security settings.
Will installing the latest Acrobat update stop the credential prompts?
Not necessarily. While keeping your software updated is highly recommended, this specific prompt loop is tied to Office 365 and SharePoint integration policies. You must manually configure your Trusted Sites and authentication settings to resolve it.
How can I open the PDF if I cannot fix the Acrobat integration issue?
You can bypass the Acrobat prompt by downloading the PDF file from SharePoint directly to your local computer's hard drive first, or by using a lightweight alternative like WPS Office to open the downloaded file.
