Users are encountering Error 2604 when attempting to enter a password to log into Microsoft Office applications on Android devices.

How to Fix Microsoft Office Error 2604 on Android Devices

Product: Microsoft Office / Excel
Device & OS: Android
Scenario: Trying to sign into the Office or Excel app on an Android phone or tablet.
Observed behavior: The application displays a 'No Network Connection' error 2604 and blocks login, even though the device is connected to the internet and other apps like Outlook function normally.

Before you start

Verify that your Android device has a stable internet connection by toggling between Wi-Fi and mobile data to rule out local network blocking or router issues.

Solution 1Recommended

Clear Office App Cache and Update Services

This removes corrupted temporary files and ensures Google Play Services can properly handle the Microsoft authentication process.

Android authentication heavily relies on Google Play Services and local app data. A corrupted cache can cause the app to falsely report a lack of network connection during login.

Open App Settings

Navigate to your Android device's 'Settings', select 'Apps' or 'App Management', and locate the Microsoft Office or Excel app from the list.

Clear App Cache and Data

Tap on 'Storage' or 'Storage usage', then select 'Clear Cache'. If the issue persists, return here and select 'Clear Data' (note that this resets the app's local preferences).

Update Apps and Services

Open the Google Play Store, search for both 'Microsoft Office' and 'Google Play Services', and tap 'Update' to ensure you are running the latest versions.

Restart and Log In

Restart your Android device, launch the Microsoft Office app, and attempt to enter your password again.

Windows TLS Fix Incompatible: You may see advice online to change TLS settings via 'inetcpl.cpl' or Internet Options. This workaround only applies to Windows PCs and cannot be performed on Android devices.

Solution 2

Reinstall the Microsoft Office Application

A clean installation replaces missing or damaged installation files that cause persistent network connection errors.

Frequently Asked Questions

Why does Error 2604 say 'No Network Connection' when my internet works?

Error 2604 specifically targets the authentication server connection. Even if your internet is active, outdated Google Play Services, corrupted app caches, or temporary server outages can prevent the Office app from reaching Microsoft's login servers, triggering this error.

Can I fix Android Error 2604 using the Windows Internet Options method?

No. The popular fix involving enabling TLS 1.0, 1.1, and 1.2 through 'inetcpl.cpl' on Windows strictly applies to desktop PCs. Android manages its network security protocols independently through OS updates.

What should I do if standard Android troubleshooting doesn't fix Error 2604?

If clearing your cache, updating apps, and switching networks does not resolve the issue—especially if the error happens across multiple Android devices—there may be an issue with your specific Microsoft account or a backend service problem. In this case, you should contact Microsoft Support.
