Fortunately, there are simple ways to fix this issue. This guide will walk you through easy steps to stop Microsoft Office from constantly asking you to sign in.

Whether you are using Office 365, Office 2019, or other versions, these solutions apply broadly. The cause of the problem often relates to account settings, licensing, or corrupted files. Taking a step-by-step approach helps to find and fix the root cause.

Each solution here is explained in detail, so even if you are not very tech-savvy, you can follow along without confusion. Just take your time and try the steps in order from easiest to more advanced.

By the end of this article, you should be able to use Microsoft Office without annoying sign-in prompts popping up repeatedly.

Quick Note: Before You Start

  • Make sure your Windows 11 and Microsoft Office are fully updated. Updates often fix bugs.
  • Check your internet connection is stable because Office needs to verify your account online.
  • Have your Microsoft account email and password ready for any sign-in attempts.
  • Close all Office applications before performing the troubleshooting steps.

Step 1: Sign Out and Sign In Again in Office

Sometimes, Office can get “stuck” with an outdated account token. Signing out and back in refreshes your credentials and often solves the problem.

  1. Open any Office app like Word or Excel.
  2. Click on your profile icon in the top right corner.
  3. Select Sign out from the dropdown menu.
  4. Close all Office applications completely.
  5. Reopen any Office app and sign back in using your Microsoft account.

This step ensures your Office apps have a fresh connection to your account, which can stop repeated sign-in prompts.

Step 2: Clear Office Credentials from Windows Credential Manager

Windows Credential Manager stores your saved passwords and tokens. Sometimes old or corrupted credentials cause Office to keep asking for sign-in.

  1. Press Win + S and type Credential Manager, then open it.
  2. Click on Windows Credentials.
  3. Look for any credentials related to Microsoft Office, Office 365, or your email address.
  4. Click on each relevant entry and select Remove.
  5. After removing, restart your computer.
  6. Open an Office app and sign in again.

Removing outdated credentials forces Office to create new, valid tokens for your account.

Step 3: Check for Multiple Microsoft Accounts

If you have signed into multiple Microsoft accounts on your PC, Office might get confused about which account to use.

  1. Open any Office app and click your profile icon.
  2. Look at the list of signed-in accounts.
  3. If you see accounts you do not use or recognize, sign out of them.
  4. Make sure only your main working account remains signed in.

Cleaning up extra accounts can reduce sign-in conflicts and repeated prompts.

Step 4: Repair Microsoft Office Installation

If the problem persists, your Office installation files might be corrupted. Repairing Office can fix such issues.

  1. Press Win + I to open Settings.
  2. Go to Apps > Installed apps or Apps > Apps & features.
  3. Find Microsoft Office in the list and click the three-dot menu next to it.
  4. Select Modify.
  5. Choose Quick Repair first, then click Repair.
  6. If Quick Repair doesn’t fix the issue, repeat and choose Online Repair (requires internet).
  7. Once done, restart your PC and open Office to check if the sign-in prompt stops.

Repairing Office restores necessary files and settings that might be causing the sign-in loop.

Step 5: Disable Simplified Account Creation (Advanced)

Sometimes, Windows 11’s account settings can interfere with Office sign-in. Disabling simplified account creation can help.

  1. Press Win + R, type regedit, and press Enter to open Registry Editor.
  2. Navigate to: HKEY_CURRENT_USERSoftwareMicrosoftOffice16.0CommonIdentity
  3. If the EnableADAL DWORD exists, double-click it and set its value to 1.
  4. If it doesn’t exist, right-click on the right panel, choose New > DWORD (32-bit) Value, name it EnableADAL, and set the value to 1.
  5. Close Registry Editor and restart your computer.
  6. Try signing into Office again.

This setting enables modern authentication, which is more reliable and secure for Office 365 accounts.

Alternative Method: Use Microsoft Support and Recovery Assistant

Microsoft offers a free tool called Support and Recovery Assistant (SaRA) that can automatically diagnose and fix Office sign-in problems.

  • Download it from the official Microsoft website: Microsoft Support and Recovery Assistant
  • Run the tool and select the Office Sign-in issue.
  • Follow the on-screen instructions to let it detect and fix problems.

This is a helpful option if the manual steps feel too complicated or don’t resolve the issue.

Frequently Asked Questions (FAQs)

Why does Microsoft Office keep asking me to sign in?

Repeated sign-in prompts usually happen due to corrupted credentials, expired tokens, multiple signed-in accounts, or issues with Office licensing. Network problems or outdated software can also cause it.

Will signing out and back in delete my Office files?

No, signing out only affects your account login. Your documents and files saved locally or on OneDrive will remain safe.

Is it safe to clear credentials from Credential Manager?

Yes, it is safe. Clearing credentials removes saved passwords and tokens, forcing Office to ask for fresh login details. Just make sure you remember your Microsoft account password.

Do I need internet access to fix this issue?

Yes, Office sign-in requires a stable internet connection to verify your account and license status.

Can this problem happen on other versions of Windows?

Yes, but this guide focuses on Windows 11. Similar steps apply to Windows 10 and earlier versions.

When Nothing Works

If you have tried all the above steps and Microsoft Office still keeps asking you to sign in, consider the following:

  • Contact Microsoft Support: Visit Microsoft Support for personalized help.
  • Reinstall Office: Uninstall Office completely and then reinstall it from your Microsoft account portal.
  • Check Your Subscription: Ensure your Office 365 subscription is active and has no billing issues.
  • Use a Different User Account: Create a new Windows user profile and see if Office behaves normally there.

These last-resort options can often resolve deeper software or account problems.

Conclusion

Microsoft Office repeatedly asking you to sign in on Windows 11 is a common but fixable problem. Starting with simple actions like signing out and clearing credentials often solves the issue quickly. If needed, repairing Office or adjusting account settings helps as well.

Always keep your software updated and maintain a stable internet connection for smooth Office experience. If problems persist, tools like the Microsoft Support and Recovery Assistant or official support channels can provide additional assistance.

Following this step-by-step guide will help you get back to working in Office without interruptions from constant sign-in requests.
