Please sign in to reactivate this app.

No Subscription Found

We couldn't find a subscription connected to your account.

Cause

This issue occurs because a previously activated version of Office Mobile exists on the device, possibly from another subscription. Therefore, the new Office Professional Plus license cannot be applied.

Solution

To resolve this issue, follow these steps:

1. Verify that you have a license assigned to youin the Microsoft 365 portal. To do this, follow these steps:

   Note

   If you cannot sign in or do not see the Settings button, then you may not have administrative permissions or may not have a license assigned to you.

   1. Sign in to the Microsoft 365 portal.

   2. In the left pane, select Subscriptions.

      

   3. In the list of subscriptions and licenses, scroll down to the Office 365 <edition> section, and then look for The latest desktop version of Office. If you see this entry in the list, you have an Office subscription that's assigned correctly.

      Note

      If you don't see a vertical scroll bar, hover the pointer over the list, press and hold the left mouse button, and then scroll.

      

   4. If an entry for The latest desktop version of Office does not appear in the list, contact your administrator or go to the following website:
