How to Repair Your Microsoft Office 365 Installation

Microsoft Office applications at some time or another will break. Examples include applications in the suite not opening, responding, or error messages. Fortunately, the suite includes tools you can use to fix these types of problems.

Recently, I had an issue with Outlook not launching at all; it just remained stuck on the splash screen. Disabling addons did not help either. So, I turned to the next best option which is to repair Office. Microsoft refined the repair options with the Office 365 release based on Click-to-Run technology that makes it easily to access repair files over the internet, no need for install media.

Repair Microsoft Office 365

Start by opening Programs and Features in the Control Panel. In Windows 10 you can get there by pulling up the hidden quick access menu.

Once you’re there, select Microsoft Office 365 in the program list and then Change/Repair on the command bar.

Now, wait while the repair wizard starts up.

Choose the type of repair you would like to perform. Depending on the severity or availability of your Internet connection, you could try the first option, Quick Repair, which is much faster and tries to fix the problem without a data connection.

If that doesn’t resolve the problem, then go back and try the Online Repair option. For my particular issue, I ultimately had to use the Online Repair.

The repair process is straight-forward following the wizard. Note that you’ll need to save your work and close all Office programs first, and then click Repair.

Then wait while the repair process runs.

You will notice the repair experience is similar to a fresh installation. The amount of time it takes will depend on your connection speed and what the issue is.

      Blame your computer then not the software. A faulty install or something is in fault here. Do a full uninstall, delete registry keys and do a reboot, then download and install from the website and try then. Allso do a sfc /scannow with cmd (admin rights aswell)

      Uh.. no.

      Either you have a bad hard drive (eek) or it’s puked on itself.

      I would reboot and try again. Shouldn’t take longer than 30 minutes (from my experience). I’ve ran it about… 5 or 6 times over the past few years.
