How to Fix Cannot Access Microsoft 365 Apps from the Web App Launcher

Product: Microsoft 365
Device & OS: not provided
Scenario: Attempting to launch web applications like Word, Excel, or PowerPoint via the Microsoft 365 portal's app launcher.
Observed behavior: The applications are missing or fail to open from the app launcher, even though direct links, Teams, and desktop applications continue to function normally.

Before you start

Ensure you have an active internet connection and that your Microsoft 365 business subscription is currently active. Standard users should be prepared to contact their IT department if admin-level checks are required.

Solution 1Recommended

Verify the Microsoft 365 Service Health Status

Check for global Microsoft service incidents causing web apps to disappear from the launcher.

Often, missing apps in the web launcher are caused by backend Microsoft server outages (such as incident MO544165). Checking the health dashboard will confirm if this is a known issue currently being fixed by Microsoft.

Log in to Admin Center

Navigate to the Microsoft 365 Admin Center using an account with administrator privileges.

Navigate to Service Health

In the left-hand navigation pane, click on 'Health' and then select 'Service health' from the dropdown menu.

Look for active incidents

Review the list of active advisories and incidents affecting app access. If a related incident is listed, you must wait for Microsoft to restore service.

Verify the Microsoft 365 Service Health Status

Admin Access Required: You must have administrator privileges to access the Service Health Dashboard. If you are a standard user, ask your IT department to check this for you.

Solution 2

Verify User Licenses and Application Assignments

Ensure the user account has the correct licenses assigned and that individual apps are enabled.
