Credential prompt after you rest the mouse pointer over the name of a user in SharePoint Online

  • Article
  • Applies to:
    SharePoint Online, OneDrive for Business

Problem

Consider the following scenario:

  • You're using Microsoft Office 2016 Click-to-Run.

  • You're using a Microsoft 365 Exchange Online mailbox, with Modern Authentication enabled.

In this scenario, you may be prompted for credentials intermittently and multiple times in SharePoint Online. This behavior may start to occur when you browse to a SharePoint Online or OneDrive for Business library, and you rest the mouse pointer on the name of a user (such as the Modified By user).

Solution/Workaround

To work around this issue, disable the NameCtrl Class add-on in Internet Explorer. To do this, following these steps:

  1. Open Internet Explorer, click the Settings icon, and then click Manage add-ons.

  2. Under Add-on Types, select Toolbars and Extensions.

  3. Under Show, select All add-ons.

  4. Under the Microsoft Corporation section, select the NameCtrl Class add-on, and then click Disable.

  5. Click Close.
