microsoft not properly work like word,excel

As your issue description is primarily written in English, I will provide my response in English for your convenience. Please feel free to let me know if you would prefer the information in another language.

Dear shubham,

As a forum moderator, I am not able to check your device or Office installation to diagnose and fix this directly. My role here is limited to providing general guidance you can apply from your side. Since both Word and Excel are affected, the problem is likely with the Office installation rather than a single app. As a first step, please try repair office:

1. Close all Office apps.
2. Go to Settings > Apps > Installed apps.
3. Find Microsoft 365, select the three dots, then select Modify > Quick Repair/Online repair

If you can't modify Office because the device is managed by your organization, please contact your IT administrator. If the issue continues, could you please share a few more details?

• What happens when you open Word or Excel?
• Is there an exact error message or code?
• Can you create a new blank document, or do the apps close immediately?
• Does the issue affect every Office application?
• Does Office show Unlicensed Product, Activation Required, or Product Activation Failed?
• Did the problem begin after an Office or operating-system update?
• Is this a personal, work, or school license?

A screenshot of what you see would also help a lot. Please mask any personal information such as your name, email address, or account details before posting it. Once you share these details, I will do my best to help you sort this out. Looking forward to your reply.
