There are several reasons why this error might occur. Third-party security software can block the update, or corrupted system files or Office itself can cause it. Other factors like connectivity issues, insufficient disk space, or incomplete installation of previous updates can also be the culprit.

  dism /online /cleanup-image /checkhealth
  dism /online /cleanup-image /restorehealth
• Restart your PC.

Fix 5. Disable or uninstall third-party software

Third-party security software, VPNs, and firewalls can cause Office update errors because they can interfere with the update process. These security programs are designed to protect the user's system by monitoring and controlling network traffic, which can sometimes block legitimate applications and updates from running properly.

When a user tries to update Office, the update program tries to establish a connection with Microsoft's servers to download and install the latest updates. However, security software, VPNs, and firewalls can mistakenly identify this connection as a potential threat and block it.

Additionally, some security software may not be compatible with Office updates or may interfere with certain files or components required for the update to run correctly. This can cause Office update error 30015-26 to occur.

Fix 6. Reinstall Office

If none of the above solutions helped, try reinstalling the app.

• Right-click on Start and pick Apps and Features.
• Scroll down to find the MS Office installation.
• Click Uninstall and confirm with Uninstall.
• Follow on-screen instructions to remove the app completely.
• Reboot the PC and then reinstall Microsoft office.

Note: if this doesn't work, you might have to use a thorough uninstall of the Office suite by using a special tool from Microsoft [download link]. You can also download it from the official website.
