Cannot log into or use copilot app on android.

Install or update the Microsoft Copilot app from its Google Play listing, then open it directly from the Play Store rather than using the button that keeps redirecting you.

The former Microsoft 365 Copilot app is now named Microsoft Copilot, with an updated name and icon. Android access is provided through this app, and the account used to sign in determines whether the personal or licensed work experience appears.^1^

1. Check the Play Store button

Open the official listing: Microsoft 365 Copilot on Google Play.

• Install — install it, then tap Open.
• Update — update it, then tap Open.
• Open — tap it directly. The app should open on the Chat home screen for an eligible Microsoft 365 subscriber.^2^
• Not compatible or unavailable — check the listing’s device or regional availability information. Microsoft notes that availability varies by country.^3^

2. If Open sends you back to the Play Store

Treat this as an installation/store loop rather than a license problem:

1. Open Android Settings → Apps → Google Play Store.
2. Tap Force stop, then Storage & cache → Clear cache.
3. Repeat those steps for Google Play services.
4. Return to Google Play and open or update Microsoft Copilot again.

If that does not resolve it, clear the Play Store’s data from Settings → Apps → Google Play Store → Storage → Clear data. This resets Play Store data, not your Microsoft 365 documents.^4^

3. Sign in with the licensed account

After the app opens:

1. Select Sign in.
2. For an organization-provided Microsoft 365 Copilot subscription, choose the work or school account carrying the license.
3. For a personal Microsoft 365 subscription, use the associated personal Microsoft account.
4. Check the profile/navigation pane for the Work or Personal label to verify which account is active.^1^

If multiple Microsoft accounts are present, signing in successfully with an unlicensed account will not provide the licensed experience.

Temporary workaround

While resolving the Android redirect, open the Copilot web app at https://www.copilot.com and sign in with the same licensed account. Microsoft supports Copilot through web, desktop, and mobile access.^1^

If the web version recognizes the subscription but the Android app does not after it opens, report the issue from an Office mobile app through side menu → Settings → Send Feedback or Online Help and Support.^3^
