Microsoft 365 and its apps appear to be having issues

First verify that the same Microsoft account holding the active subscription can sign in online, because failures across Windows and iPhone apps should be separated from device-local Office problems before repairing either device.

1. Verify the account and subscription

1. Open the Microsoft account Services & subscriptions page in a private browser window and sign in with the email address used to purchase Microsoft 365.
2. Confirm that Microsoft 365 appears as Active. If it is missing, sign out and try any other Microsoft account you may have used for the purchase. Microsoft specifically requires signing in with the account associated with the subscription.^1^
3. In that same browser session, test Outlook, OneDrive, and the Microsoft 365 web apps. These web apps can provide temporary access to email, calendar, and documents while the installed applications are repaired.[^2^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID]'re-still-getting-notifications-after-renewing-or-buying-microsoft-365 "A subscription notice appears when I open a Microsoft 365 application | Microsoft Support")

If the account itself cannot sign in, use Microsoft’s sign-in helper or Get Help. Support agents cannot directly change account details or send password-reset links.^3^

The public consumer status currently reports Outlook.com, OneDrive, and consumer Copilot as operational, so there is no listed broad consumer outage matching all these symptoms.^4^

2. Repair Microsoft 365 on Windows 11

If the subscription and web apps work but the Windows applications still deny access:

1. Restart Windows first, then test Outlook again.
2. Right-click Start and select Installed apps.
3. Find Microsoft 365 or Office.
4. Select the … menu → Modify.
5. For a Click-to-Run installation, select Online Repair → Repair. For an MSI installation, select Repair → Continue.
6. Restart the PC when completed, open an Office application, and sign in with the account verified in step 1.

Online Repair repairs the entire Microsoft 365/Office installation, not only Outlook. It requires an internet connection, can take some time, and Windows may request administrator approval.^5^

If Office displays Product Deactivated, select Sign in and use the subscription-owning account. If it displays Couldn’t Verify Subscription, reconnect to the internet and select Retry.[^2^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID]'re-still-getting-notifications-after-renewing-or-buying-microsoft-365 "A subscription notice appears when I open a Microsoft 365 application | Microsoft Support")

3. Address OneDrive on the iPhone separately

An iPhone not appearing in the Microsoft account’s normal device list is expected: Microsoft currently does not support adding iOS devices to that list. Windows 11 PCs are added automatically when signed in; only Surface devices can be registered manually by serial number.^6^

For a OneDrive sign-in failure, first open OneDrive and sign in with the same verified account. If the credentials are rejected there too, use the Microsoft account sign-in helper rather than resetting the app.^7^

Only if sign-in succeeds but OneDrive has local sync, camera-upload, or similar app problems:

1. Open OneDrive → Profile → Settings → Account.
2. Select the affected account, then Reset.
3. If it remains broken, uninstall and reinstall OneDrive.^8^

4. Escalate if online access also fails

If the active subscription is visible but Outlook, calendar, OneDrive, and Designer also fail in a private browser session, contact Microsoft Support through Get Help and provide:

• Whether the account is Microsoft 365 Personal/Family or work/school
• Exact error text and codes
• Whether web access fails as well as installed apps
• When the problem began
• A screenshot with personal information removed

For a work or school account, only the organization’s Microsoft 365 administrator can inspect Microsoft 365 admin center → Health → Service health for tenant-specific incidents or reassign the license.^9^
