Copilot Redirect Loop Error | Fix

Facing a Copilot redirect loop error? Learn how to fix login redirects, authentication loops, and loading issues in Microsoft Copilot quickly and clearly.

What Is the Copilot Redirect Loop Error?

If you’ve tried to sign in to Microsoft Copilot and found yourself stuck in a continuous redirect cycle, you’ve likely encountered the Copilot redirect loop error. This issue typically occurs when you attempt to access Copilot via Word, Excel, Teams, or the web—only to be bounced back and forth between login pages or kept on a loading screen that never progresses.

Unlike errors that block features after login, this one prevents you from even reaching Copilot’s main interface. It’s often caused by broken authentication tokens, browser or app cache conflicts, or identity service misconfigurations. In some cases, it might look like Copilot is about to load, but it redirects again and again—creating a frustrating loop.

Let’s explore why this problem matters and how to fix it:

• 🔁 Blocks Access to Copilot Entirely: You can’t even begin using the tool if login fails repeatedly.
• 🛑 May Indicate Identity or Token Problems: This often means there’s a problem with your Microsoft account session.
• ⚠️ Interrupts Daily Workflow: Without access, you miss out on time-saving Copilot features.
• 🔄 Affects All Devices or Browsers: The error may follow you across platforms if not resolved properly.
• 🤯 Can Lead to Confusion and Delays: Many users think it’s a server issue when it’s local or session-related.

Thankfully, the Copilot redirect loop error can be fixed using clear steps. Let’s break it down.

Here’s a breakdown of the most common triggers:

🛠️ How to Fix Copilot Redirect Loop Error

Ready to get back into Copilot? These step-by-step solutions are simple, effective, and proven to stop the Copilot redirect loop error on both browser and desktop environments.

1. 🔁 Sign Out and Back Into Microsoft 365

🧠 Why it works:
Refreshes authentication tokens and forces a new secure session.

📌 How to do it:
• Sign out of all Microsoft 365 apps (Teams, Word, Excel, browser)
• Close the apps completely
• Reopen and sign back in with your main Microsoft account

2. 🧹 Clear Browser Cache and Cookies

🧠 Why it works:
Stale browser data causes Microsoft sign-in loops.

📌 How to do it:
• Open browser settings
• Clear cache, cookies, and site data
• Restart the browser and access Copilot again

3. 🧰 Reset Office or Teams Cache

🧠 Why it works:
Old session data conflicts with new login attempts.

📌 How to do it:
• Go to %appdata%\Microsoft\Teams
• Delete folders like Cache, blob_storage, and IndexedDB
• Restart Teams or Office and retry Copilot access

4.🔒 Fix Copilot Authentication Loop With InPrivate/Incognito

🧠 Why it works:
Bypasses stored login data that causes conflicts.

📌 How to do it:
• Open your browser in private/incognito mode
• Go to office.com or teams.microsoft.com
• Try launching Copilot

5.🔧 Disable VPN or Proxy Temporarily

🧠 Why it works:
VPNs and proxies can block authentication endpoints, leading to redirect loops.

📌 How to do it:
• Turn off your VPN or proxy from system or browser settings
• Restart your app and sign in again

6. 🌐 Use a Different Browser or Device

🧠 Why it works:
Isolates the issue to a specific environment (browser or desktop).

📌 How to do it:
• Try a different browser (Edge, Chrome, Firefox)
• Alternatively, test on another device using the same Microsoft account
• If it works elsewhere, clear cache and restart original device

📤 Update Microsoft 365 Apps

🧠 Why it works:
Older versions may have unresolved login or UI bugs.

📌 How to do it:
• Open Word or Teams > File > Account
• Click “Update Options” > “Update Now”
• Restart after installation completes

7. 🧪 Check Microsoft Copilot License Assignment

🧠 Why it works:
Misconfigured licenses cause failed authentication redirects.

📌 How to do it:
• Visit Microsoft 365 Admin Center
• Go to Users > Active Users
• Confirm your account has “Copilot for Microsoft 365” license assigned

8. 🧩 Remove Duplicate Microsoft Account Profiles

🧠 Why it works:
Multiple saved profiles can conflict and trigger authentication loops.

📌 How to do it:
• In Windows: Go to Settings > Accounts > Email & Accounts
• Remove unused or duplicate Microsoft accounts
• Keep only your main organizational profile

9. 🛠️ Fix Copilot Sign-In Error with OneDrive Reset

🧠 Why it works:
OneDrive cache sync problems can interfere with Office identity services.

📌 How to do it:
• Right-click OneDrive > Settings
• Click “Unlink This PC” and sign in again
• Relaunch Word or Excel and try using Copilot

🧪 Advanced Troubleshooting Tips

If the standard steps did not resolve your Copilot redirect loop error, these more advanced methods can help. Ideal for IT professionals or technically confident users.

1. 🧠 Clear Windows Credential Manager Entries

🧠 Why it works:
Stored credentials can contain expired tokens.

📌 How to do it:
• Open Control Panel > Credential Manager
• Remove any entries under “Windows Credentials” or “Generic Credentials” with Microsoft references
• Restart the device and log in again

2. 🔍 Use Fiddler or DevTools to Inspect Redirects

🧠 Why it works:
You can monitor what authentication call is looping.

📌 How to do it:
• Open Copilot in a browser
• Press F12 > Go to Network tab
• Look for repeated 302/401 redirects or failed tokens

3. 🔐 Verify Conditional Access Policies in Azure AD

🧠 Why it works:
Too strict access controls may cause redirect loops during login.

📌 How to do it:
• Log into Azure Portal > Azure Active Directory > Conditional Access
• Review policies affecting AI or Copilot services
• Temporarily disable for testing

4. ⚙️ Create a New Windows User Profile

🧠 Why it works:
Corrupt user profiles cause inconsistent login behavior across Microsoft apps.

📌 How to do it:
• Go to Settings > Accounts > Family & Other Users
• Add a new user and log in
• Try accessing Copilot under the new profile
