Hi,

, Remove MS Office first and reinstall:

https://yourwindowsguide.com/2026/02/how-to-uninstall-microsoft-office.html

Here is how to use it:

Go to https://aka.ms/SaRA-officeUninstallFromPC to open the Get Help App.
When the tool opens, select Yes, and then click Next.
Choose the option to uninstall Microsoft 365, then follow the steps.
The tool will automatically detect your Office version and remove Microsoft 365 completely using a PowerShell window. It may take 10 to 15 minutes.
Reinstall again.

I look forward to hearing from you to get the results of the troubleshooting.

Answer 2

Run an Online Repair of Microsoft 365 or Office, because it repairs the entire Office installation containing both Outlook and Excel rather than only the application displaying the message.

Repair Microsoft 365 or Office

Close Outlook, Excel, and all other Office applications.
Open the repair settings:
- Windows 11: Right-click Start → Installed apps.
- Windows 10: Right-click Start → Apps and Features.
Find Microsoft 365 or Microsoft Office.
On Windows 11, select the three dots beside it, and then select Modify. On Windows 10, select the product and then Modify.
If the installation is Click-to-Run, select Online Repair → Repair. This is more comprehensive than Quick Repair.
If an MSI-based repair window appears instead, select Repair → Continue.
Complete the prompts and restart Windows when finished.
Open Excel and Outlook normally and test them.

This repairs the whole Office suite even when only particular applications are failing. Online Repair requires an Internet connection and can take longer because it performs the more complete repair process.^1^

If Online Repair does not resolve it

Test each application in Office Safe Mode, which starts it without most add-ins:

Press Windows key + R.
Enter the following command for Excel:

excel /safe

Repeat with Outlook:

outlook /safe

The space before /safe is required. If an application opens in Safe Mode, an add-in is likely interfering with normal startup.^2^

For each application that opens in Safe Mode:

Select File → Options → Add-ins.
At the bottom, select COM Add-ins under Manage, and then select Go.
Record or take a screenshot of the enabled add-ins.
Clear their check boxes—disable them rather than selecting Remove.
Close and reopen the application normally.
If it now works, enable add-ins individually and restart the application after each one. Leave disabled the add-in that causes the error to return.^3^

If neither Outlook nor Excel opens in Safe Mode after Online Repair, the next supported path is to uninstall and reinstall Office.^4^
