Question details

The user is unable to sign into Microsoft Office desktop applications because the process hangs indefinitely on a blank white dialog box covering a 'Just a moment' message.

Product: Microsoft Office Desktop Apps (Word, Excel, Outlook)
Device & OS: Windows
Scenario: Attempting to log into Microsoft Office desktop apps to activate or authenticate the software.
Observed behavior: A blank white window appears during sign-in and loads indefinitely. Office for the web and OneDrive continue to function normally, but the desktop applications display an 'Access denied' script error in the Recovery Assistant.

Before you start

Ensure your computer is connected to a stable internet connection and verify that you have administrative privileges to modify Windows network and account settings.

Solution 1Recommended

Change Network Connection and Reset Internet Options

Switching to an alternative network and resetting Windows internet configurations can bypass local network restrictions or proxy issues blocking the sign-in prompt.

Often, a blank sign-in screen occurs because the local network or router is blocking the specific authentication traffic required by Office.

Connect to a different network

Disconnect from your current Wi-Fi or Ethernet and connect your PC to a mobile hotspot to rule out router-level network restrictions.

Open Internet Options

Press the Windows key, type 'Internet Options', and press Enter to open the Internet Properties dialog.

Restore Advanced Settings

Navigate to the 'Advanced' tab, click on 'Restore advanced settings', then click 'Apply' and 'OK'. Restart your Office application and attempt to sign in again.

Solution 2

Perform a Windows Clean Boot

A clean boot helps determine if third-party startup software, firewalls, or security tools are interfering with the Office authentication module.

Solution 3

Create a New Local Windows User Account

Corrupted Windows user profiles can prevent Microsoft apps from successfully authenticating. Testing on a new local account can isolate this issue.

Frequently Asked Questions

Why does my Microsoft Office sign-in screen remain blank?

A blank sign-in screen is typically caused by network connectivity issues, outdated TLS security protocols, interference from third-party antivirus software, or a corrupted Windows user profile.

Will reinstalling Office fix the blank sign-in dialog?

Often, reinstalling Office will not fix this issue if the root cause lies within your network configuration or a corrupted local user profile. It is recommended to reset your Internet Options or try a mobile hotspot first.

How can I bypass the Office sign-in screen?

You cannot bypass the sign-in screen if you need to activate a Microsoft 365 subscription. However, ensuring your network is not blocking Microsoft's authentication servers usually allows the prompt to load correctly.

What should I do if the Microsoft Support and Recovery Assistant shows an 'Access denied' script error?

This specific error often indicates that your current Windows user profile lacks the necessary permissions or is corrupted. Creating and logging into a new local Windows administrator account is the most effective way to test this.
