Before you start

Ensure that your computer is connected to a stable internet network and save any ongoing work in your Office applications before attempting to run repairs or updates.

Solution 1

Temporarily Disable Network Security and VPN

Network security software or virtual private networks can sometimes block communication with Microsoft update servers, causing the update to fail.

Firewalls, antivirus programs, and VPNs monitor and sometimes restrict network traffic. Temporarily pausing these services can help determine if they are the root cause of the update blockage.

1
Disconnect VPN

Open your VPN client and disconnect from the active server.

2
Pause Antivirus/Firewall

Navigate to your antivirus settings or Windows Security and temporarily disable the firewall and real-time protection.

3
Retry the Update

Open any Office app like Word, go to File > Account > Update Options, and click Update Now.

4
Re-enable Security

Once the update is complete (or if it fails again), immediately re-enable your firewall and antivirus to keep your system secure.

Frequently Asked Questions

Why does Microsoft 365 say "Something is missing" during updates?

This error typically occurs due to network connectivity issues blocking the update servers, overactive antivirus or firewall software interrupting the download, or corrupted Microsoft 365 installation files on your system.

Will running an Online Repair delete my Office files?

No, running an Online Repair only fixes the application files, registry keys, and software settings. Your personal documents, spreadsheets, and presentations saved on your local hard drive or OneDrive remain completely safe and unaffected.

How long does the Microsoft 365 Online Repair take?

The Online Repair process usually takes 10 to 30 minutes, depending on your internet connection speed. Unlike the Quick Repair, it needs to redownload the necessary installation files directly from Microsoft servers.
