Ensure you have your Microsoft 365 account credentials handy and a stable internet connection before attempting to repair your installation or verify your license status.
Verify Microsoft 365 License Status and Use Outlook on the Web
Check with your administrator or via the web portal to ensure your account has an active Microsoft 365 license assigned.
Often, the desktop application fails to recognize a license due to sync delays or administrative changes. Checking the web version confirms if the license is valid on the server side.
Open a web browser and navigate to outlook.office.com. Log in with your Microsoft 365 credentials to see if you can access your mailbox.
If you are part of a school or organization, ask your Microsoft 365 administrator to verify that your account has the correct Office desktop license assigned.
If the administrator has just assigned or renewed the license, keep in mind that newly assigned licenses can take up to 72 hours to fully replicate to the desktop apps.

Frequently Asked Questions
Why does Outlook say 'Unlicensed Product' when I have a subscription?
This can happen if Microsoft's activation servers fail to recognize your account, if your subscription recently expired, or if there is a local cache issue. Newly assigned licenses can also take up to 72 hours to reflect in the desktop application.
What is the difference between Quick Repair and Online Repair for Microsoft 365?
Quick Repair fixes minor issues using files already present on your computer and works offline. Online Repair completely reinstalls the Office applications by downloading fresh files from Microsoft's servers, making it much more effective for persistent licensing and crash errors.
Can I still access my emails if Classic Outlook won't open?
Yes, you can access your mailbox by logging into Outlook on the web (outlook.office.com) using your Microsoft 365 credentials. This allows you to work normally while you troubleshoot the desktop app.
